MX-K-02: The 2013 Energy Reform and Its Reversal — Pemex, the Opening, and the Counter-Reform (2013–2026)

Status: DRAFTWords: 8,660

1. Key Takeaways

  • The 20 December 2013 constitutional amendments to Articles 25, 27, and 28 — passed by the Senate 95–28 on 11 December and the Cámara de Diputados 354–134 on 12 December 2013, ratified by the required majority of state legislatures within a week — ended the seventy-five-year exclusion of private and foreign capital from Mexican upstream hydrocarbons that had stood since the 18 March 1938 Lázaro Cárdenas expropriation. It was the most symbolically charged constitutional change of the post-2000 democratic period: the 1938 expropriation is Mexico's foundational economic-sovereignty myth, commemorated annually as a civic date, and Pemex its institutional embodiment. The 2013 decision deliberately modified the myth's legal core while preserving its doctrinal shell (subsoil hydrocarbons remained the Nation's property; private operators acquired contract rights, not concessions).

  • The reform was made possible by an unrepeatable political vehicle — the Pacto por México, the PRI-PAN-PRD agreement signed 2 December 2012 (MX-B-02) — and it was the reform that destroyed that vehicle. The PRD withdrew from the Pact on 28 November 2013 when the PRI and PAN agreed to include the licence modality; the constitutional amendment passed on PRI-PAN votes against the parliamentary left. The energy reform was therefore, alone among the Peña Nieto structural reforms, an elite two-party pact rather than a three-party consensus — a construction defect that defined its political vulnerability for the following decade.

  • The reform's operational case was real and largely uncontested even by critics: Pemex was in structural decline. National crude production had peaked at approximately 3.4 million barrels per day in 2004 [TBD-VERIFY: commonly cited peak is 3.38–3.4 mb/d in 2004; confirm against Sener/CNH series] and fell continuously thereafter as the Cantarell super-giant collapsed; the company carried a fiscal regime that had historically extracted the large majority of its operating profit — Pemex provided roughly one-third of federal budget revenue at its 2000s peak [TBD-VERIFY: federal-revenue share figures range ~30–40% mid-2000s, declining to under 20% by the late 2010s] — leaving it decapitalised, indebted, and technologically unable to develop deepwater and unconventional resources. The 2008 Calderón mini-reform (incentivised service contracts, the first CNH) had tested the limit of what was possible without constitutional change and found it insufficient.

  • The 2013 decision was sold internationally as "Mexico's moment" — the Economist and Time cover treatment, the Davos circuit, projections of 3 mb/d production by 2025 and tens of billions in annual investment — and sold domestically with a promise that proved fatal: that the reform would lower gasoline, gas, and electricity prices. The 1 January 2017 gasolinazo — the staged liberalisation of gasoline prices producing an approximately 14–20 per cent overnight increase, followed by nationwide protests, looting, and deaths [TBD-VERIFY: casualty and arrest figures for January 2017 protests] — delivered the reform's political bill before its economic benefits had materialised, and became López Obrador's single most effective campaign exhibit in 2018.

  • The reversal, 2019–2024, was administrative before it was constitutional. AMLO — who had framed the 2013 reform as traición a la patria (treason against the fatherland) from the moment of its passage, and whose movement had attempted and failed to force a 2014 popular consultation on repeal (blocked by the SCJN in October 2014) — did not abrogate the amendment or the 107 awarded contracts. Instead he suspended new auction rounds from December 2018, redirected fiscal resources into Pemex rescues and the Dos Bocas (Olmeca) refinery, inverted electricity dispatch in CFE's favour (the May 2020 Sener decree and the March 2021 Ley de la Industria Eléctrica amendments), and strangled the reform's regulators administratively when his April 2022 constitutional electricity counter-reform failed in the Chamber — his only major legislative defeat of the sexenio, consoled the same week by the lithium nationalisation passed by simple majority.

  • The reversal had an external price the reform's architects had built in: the July 2022 USMCA energy consultations, in which the United States and Canada formally challenged the CFE-prioritisation measures as violations of national-treatment and state-owned-enterprise commitments (MX-B-04, MX-E-02). The consultations never proceeded to a panel — successive US administrations judged the bilateral relationship too loaded with migration, fentanyl, and (after 2025) tariff files to detonate the energy dispute — but they fixed energy as a standing item in the 2026 USMCA review (MX-D-05, MX-D-06) [TBD-VERIFY: status of energy file within the 2026 joint-review process].

  • The Sheinbaum consolidation completed constitutionally what AMLO had achieved administratively. With the Morena supermajority delivered by the 2024 election, the October–November 2024 constitutional reform redefined Pemex and CFE from empresas productivas del Estado to empresas públicas del Estado — removing the 2013 settlement's commercial-governance category and re-entrenching state primacy, including CFE's guaranteed majority share of electricity supply [TBD-VERIFY: precise DOF dates and the codified CFE generation-share floor, commonly reported as 54%]. A companion reform dissolved the autonomous regulators — CNH and CRE absorbed into a new Comisión Nacional de Energía under Sener [TBD-VERIFY: institutional details of the 2024–25 regulatory reorganisation] — eliminating the independent-regulator architecture that had been the 2013 reform's institutional signature. The counter-reform passed in weeks, against a fragmented opposition, with none of the 2013 reform's negotiation.

  • The pair constitutes Mexico's clearest natural experiment in reform-and-reversal politics, and the institutional lesson cuts in both directions. The 2013 reform demonstrated that a determined executive with a two-party congressional coalition could amend even the most sacralised constitutional settlement — but that a constitutional change carried without social anchoring, tainted by corruption allegations (the Lozoya-Odebrecht confessions alleging that bribes financed the reform's legislative passage [TBD-VERIFY: judicial status of the Lozoya proceedings]), and front-loaded with consumer pain, would not survive the first hostile supermajority. The 2024 counter-reform demonstrated the converse: that the reversal inherited the same defect, entrenching state primacy by supermajority fiat against the investment community and the USMCA partners, and is in principle as reversible as its predecessor.

  • What neither decision changed is the underlying constraint both claimed to solve: Pemex itself. Production continued falling through both regimes — approximately 2.43 mb/d (2013), 1.93 mb/d (2018), 1.55–1.65 mb/d (2024) [TBD-VERIFY: 2024–2026 production series] — and the company's financial debt of approximately 100 billion US dollars, plus tens of billions in supplier arrears, made it the world's most indebted oil company under both the liberalising and the nationalising settlement [TBD-VERIFY: 2025–2026 debt and arrears figures]. The fiscal cost of the AMLO-Sheinbaum rescues — cumulatively in the 70–100 billion dollar range across direct transfers, tax relief, and refinancing support [TBD-VERIFY] — is the reversal's quantifiable price; the unrealised committed investment of the suspended rounds is the opening's unquantifiable counterfactual.

  • Both decisions spoke the same political language — energy sovereignty — and that continuity is the deepest finding of the paired arc. The 2013 reformers insisted the hydrocarbons remained the Nation's and that the reform rescued sovereignty from Pemex's incapacity; AMLO and Sheinbaum insisted sovereignty meant state operation, not state ownership alone. The 1938 Cárdenas inheritance proved capacious enough to legitimate both the opening and its reversal — which is why the energy question in Mexico is never settled by economics, and why the durable equilibrium that emerged by 2026 (state primacy with bounded, subordinated private participation through desarrollos mixtos) is best read as a political settlement denominated in sovereignty, not an energy policy denominated in barrels.

2. The 1938 Settlement and Its Long Decay

2.1 The Expropriation as National Myth

No constitutional provision in Mexico carried the symbolic charge of the petroleum reservation. The 18 March 1938 expropriation decree of Lázaro Cárdenas — transferring to the state the Mexican assets of seventeen foreign oil companies after they defied a Supreme Court-confirmed labour award — was, in the standard historiography (Krauze, Meyer), the moment the Mexican Revolution acquired its economic content. Article 27 of the 1917 Constitution had already vested subsoil resources in the Nation; the 1938 decree operationalised the reservation against the British and American majors, and the popular subscription campaign of April–May 1938 — citizens donating jewellery, livestock, and coins toward the companies' indemnification — converted a labour dispute into a founding act of economic sovereignty. The 18 March anniversary became a civic date; Pemex, founded 1 June 1938, became what Lorenzo Meyer called the revolution's cathedral — simultaneously an oil company, an employment system, a fiscal apparatus, and a national symbol. The 1940 constitutional amendment prohibited private concessions outright, and the 1960 López Mateos electricity nationalisation extended the same settlement to power generation under the CFE. (The full institutional genealogy is treated in MX-G-01 §2.)

The political consequence of the myth was a standing veto. Every president from de la Madrid onward who attempted to widen private participation — the 1986 secondary-petrochemicals opening, the 1992 Salinas subsidiary restructuring, the Fox-era governance proposals — worked at the margins of the constitutional reservation precisely because frontal amendment was assumed to be politically impossible. The assumption was tested most directly in 2008 and confirmed: when Felipe Calderón proposed an energy reform that did not even touch the constitutional text, López Obrador's Movimiento en Defensa del Petróleo mobilised mass civic resistance — including the women's brigades styled adelitas and the occupation of the congressional tribunes — and the reform that finally passed in October 2008 was confined to "incentivised service contracts" with no equity or production-share interest, plus the creation of the first, weak Comisión Nacional de Hidrocarburos. The 2008 episode established the script the 2013 debate would re-run: any opening, however bounded, would be framed by the nationalist left as the sale of the patrimony.

2.2 The Decay: Cantarell, the Fiscal Milk Cow, and the Capability Gap

By the time Enrique Peña Nieto took office on 1 December 2012, the gap between the myth and the operating reality had become the central fact of Mexican political economy. Three elements composed it.

The production collapse. Mexican crude production peaked at approximately 3.4 mb/d in 2004 [TBD-VERIFY: peak-year figure, commonly cited as 3.38–3.4 mb/d], carried overwhelmingly by the Cantarell super-giant complex offshore Campeche — at its 2003–2004 peak alone producing approximately 2.1 mb/d, briefly the second-most-productive field in the world. The nitrogen-injection programme that had boosted Cantarell's recovery accelerated its exhaustion; from 2005 the complex entered one of the steepest declines ever recorded for a super-giant, falling to a few hundred thousand barrels per day by the early 2010s [TBD-VERIFY: precise decline path; MX-G-01 records ~165,000 b/d by 2018]. National production fell to approximately 2.55 mb/d by 2012 and 2.43 mb/d in 2013. The Ku-Maloob-Zaap complex partially compensated but itself approached maturity. The reserve-replacement ratio had been below 100 per cent every year since 2002: Pemex was liquidating its reserve base.

The fiscal extraction. Pemex's structural problem was not geology alone but its function as the federal treasury's milk cow. Through the 2000s the company provided roughly one-third of federal budget revenue [TBD-VERIFY: SHCP series; the share is commonly cited at 30–40% mid-2000s], extracted principally through the Derecho de Utilidad Compartida and predecessor levies that taxed upstream operating profit at marginal rates above 70 per cent. The arrangement, inherited from the PRI hegemonic era, allowed Mexico to maintain one of the OECD's lowest non-oil tax takes while Pemex booked accounting losses in most years, accumulated debt to fund even maintenance capital expenditure, and systematically under-invested in exploration. The company that was asked to arrest the Cantarell decline was simultaneously decapitalised by the state that owned it — a contradiction every finance ministry understood and none could resolve, because resolving it required either a politically impossible tax reform or a politically impossible energy opening. The 2013 package attempted both at once.

The capability gap. Mexico's remaining resource endowment lay where Pemex could not reach it: the deepwater Gulf (the Perdido fold belt adjoining producing US acreage), the Burgos basin shale formations contiguous with the Texas Eagle Ford, and enhanced recovery in mature onshore fields. Pemex had drilled deepwater exploration wells but had no deepwater production experience, no shale programme, and — under the procurement and fiscal regime then governing it — no realistic prospect of acquiring either. The 2008 reform's service-contract instrument had been tested through the 2011–2012 contratos integrales in Chicontepec and produced disappointing results: the binding constraint was not contractor incentive but the prohibition on the risk-bearing equity participation through which the international industry deploys capital and technology. This was the operational case for constitutional amendment, and it is important to the analysis of the 2013 decision that the diagnosis itself was broadly shared — AMLO's alternative was not a defence of the status quo but a Pemex-restoration programme (fiscal relief, refining investment, corruption removal) that accepted the decline diagnosis while rejecting the opening prescription.

2.3 The Decision Space in 2012

The Peña Nieto team thus inherited a problem with a known shape and a forty-year-old political constraint. What changed in 2012 was not the problem but the political opportunity: a returning PRI with plurality but not majority, a PAN ideologically committed to the opening and willing to trade, a PRD leadership under Jesús Zambrano's Nueva Izquierda current willing to negotiate institutional reforms, and a defeated AMLO who had left the PRD's orbit and not yet built Morena into a party. The window in which a two-thirds constitutional coalition could be assembled against the nationalist left was, in retrospect, open for roughly eighteen months. The energy reform was deliberately sequenced last among the Pacto reforms — after the education, telecommunications, and fiscal packages — both because it was the hardest and because the Pact's architects understood that it would break the Pact. It did.

3. The 2013 Decision

3.1 The Pacto Vehicle and the Negotiation

The Pacto por México, signed at the Castillo de Chapultepec on 2 December 2012 (treated fully in MX-B-02), contained energy commitments (points 54–60) drafted with deliberate ambiguity: Pemex would become a "productive public enterprise"; the legal framework would be modified so the state could "establish associations with the private sector" — language compatible with anything from the PRD's governance-only reform to the PAN's full concessions model. Through 2013 the three parties tabled rival initiatives along exactly that spectrum: the PAN's 31 July initiative proposing licences and concessions; Peña Nieto's 12 August executive initiative proposing profit-sharing but excluding licences — and invoking, in a calculated act of symbolic appropriation, Cárdenas's own 1940 regulatory law as precedent for state contracts with private parties; and the PRD's 19 August initiative, presented by Cuauhtémoc Cárdenas Solórzano, the expropriator's son, proposing fiscal and governance reform of Pemex with no constitutional change.

The endgame was a PRI-PAN convergence upward, toward the more liberal design. The PAN conditioned its energy votes on the political-electoral reform (re-election of legislators, the INE's creation from the IFE) being passed in parallel — a genuine cross-issue trade that explains the December 2013 legislative compression. When the consolidated PRI-PAN dictamen incorporated the licence modality — under which the contractor takes title to extracted hydrocarbons at the wellhead — the PRD's position became untenable, and Zambrano announced the party's withdrawal from the Pacto on 28 November 2013. The amendment then moved with deliberate speed: Senate approval 95–28 on 11 December 2013 (after the PRD-PT minority's tribune occupation was circumvented by relocating the session), Chamber approval 354–134 on 12 December, ratification by a majority of state legislatures — overwhelmingly PRI-governed — between 16 and 19 December, and promulgation in the Diario Oficial on 20 December 2013. From PRD withdrawal to constitutional promulgation took twenty-two days. The speed was a political choice: the reform's managers judged, correctly, that an extended ratification calendar would have given the opposition time to mobilise the 2008-style street resistance that the December compression pre-empted.

3.2 The Architecture, in Brief

The amendment's design (full treatment in MX-G-01 §§3–4) had five load-bearing elements relevant to the decision analysis. First, the doctrinal preservation: subsoil hydrocarbons remained the Nation's property, the contracts were declared not to be concessions, and the 18 March inheritance was formally honoured even as its operational content was removed — the construction through which the PRI reconciled the reform with its own historical identity. Second, the four contract modalities (service, profit-sharing, production-sharing, licence) with the licence as the politically explosive outer bound. Third, Ronda Cero: Pemex's pre-emptive retention, resolved on 13 August 2014, of essentially all producing fields and approximately 83 per cent of 2P reserves — the design feature intended to demonstrate that the reform strengthened rather than dismantled the national company. Fourth, the independent-regulator architecture — a strengthened CNH and CRE with constitutional anchoring, the new ASEA, the Banxico-administered Fondo Mexicano del Petróleo — which placed the rounds' integrity outside direct executive control and was, precisely for that reason, the first target of the later reversal. Fifth, the electricity opening: CFE unbundled, a wholesale market under the new CENACE, and competitive generation — the component that delivered the reform's most unambiguous early results and provoked the reversal's most aggressive counter-measures.

3.3 The Selling: "Mexico's Moment" Abroad, Cheaper Energy at Home

The reform's international marketing was as deliberate as its legislative engineering. The Peña Nieto government and its allies cultivated the "Mexico's moment" frame across 2012–2014 — the Economist's late-2012 special report on the rising Mexico, the February 2014 Time international cover presenting Peña Nieto under the headline "Saving Mexico" [TBD-VERIFY: the Time cover ran on international editions, February 2014; its domestic reception was largely derisive], the Davos and investor-conference circuit, and projections — embedded in the reform's own transitory-article targets — of production recovering to 3 mb/d by 2025 and investment inflows in the tens of billions annually. The international campaign succeeded on its own terms: Mexico's reform was the most praised emerging-market structural package of the decade, and the December 2016 deepwater round drew every supermajor.

The domestic selling was different and, in retrospect, fatal. The reform was marketed to Mexican households on consumer prices: official campaign material promised that the reform would lower electricity tariffs and gas prices, with gasoline-price liberalisation presented as a transition to market prices that competition would discipline downward. The promise inverted the reform's actual sequencing — liberalisation would remove subsidised administered prices before any competitive infrastructure existed to discipline them — and it gave the opposition a falsifiable claim with a date attached. No element of the 2013 communication strategy cost more than this.

3.4 The Opposition: Treason, the Consultation, and the Birth of Morena's Cause

López Obrador's framing was immediate and never varied: the reform was traición a la patria, the reversal of Cárdenas, the delivery of the patrimony to foreigners — he publicly invited Peña Nieto to choose between being remembered with Cárdenas or with Santa Anna, the president who sold national territory. The constitutional channel available to the opposition was the popular-consultation mechanism created by the 2012 political reform, and through 2014 both Morena (registered as a party in July 2014) and the PRD gathered signatures — Morena claiming several million [TBD-VERIFY: signature counts] — to force a 2015 referendum on the reform. On 30 October 2014 the SCJN ruled the consultation unconstitutional on the ground that the constitution excludes federal revenues from consultation subjects and the energy reform was revenue-implicated — a juridically defensible but politically consequential ruling that closed the institutional channel and converted repeal into Morena's founding electoral cause. The 2014 blockage matters for the arc's analysis: the reform's defenders won every institutional battle between 2013 and 2018 and thereby guaranteed that the verdict, when it came, would be delivered through the presidency itself.

AMLO suffered a heart attack in December 2013, days before the amendment's promulgation; the movement against the reform was carried through 2014–2015 by Morena's organisational build-out, for which energy nationalism served as the central recruiting narrative. By 2018, the gasolinazo (§4.3) had fused the reform, corruption (§7.1), and household energy costs into a single electoral indictment. The 2013 decision was constitutionally entrenched and politically undefended — passed by parties whose combined presidential vote in 2018 would fall to barely a third, against a movement whose victory would be read, by its leader, as the mandate the blocked 2014 consultation never delivered.

4. The Implementation (2014–2018)

4.1 The Rounds and the Headline Successes

The implementation record is documented in full in MX-G-01 (§§5–8); what matters for the decision analysis is its shape. The secondary legislation of 11 August 2014 and Ronda Cero of 13 August 2014 were delivered on the constitutional calendar. The competitive rounds then ran against the worst possible macro backdrop: Brent crude fell from approximately 100 dollars per barrel in mid-2014 — within weeks of the secondary legislation's promulgation — to below 30 dollars by January 2016. The first shallow-water auction in December 2015 awarded only two of fourteen blocks; recalibrated terms produced progressively stronger results through 2016–2018, culminating in the 5 December 2016 deepwater round — the BHP Billiton–Pemex Trion farm-out, awards to ExxonMobil, Chevron, Total, Statoil, and CNOOC, and committed minimum work of roughly 34 billion dollars [TBD-VERIFY: figures vary ~30–41bn across CNH communiqués] — and the January 2018 deepwater round in which Shell took nine blocks. By the programme's suspension, 107 contracts had been awarded to 73 operators from eighteen jurisdictions, with projected committed investment across contract terms of approximately 161 billion dollars [TBD-VERIFY: 150–200bn range depending on method].

The single most consequential operational validation came on 12 July 2017, when Talos Energy announced the Zama discovery in shallow-water Block 7 — initially estimated at 1.4–2.0 billion barrels of oil equivalent in place [TBD-VERIFY: in-place vs recoverable figures; recoverable commonly cited at 600–800 million barrels], the largest shallow-water Gulf discovery in roughly two decades and the first major find by a private operator in Mexico since 1938. Zama proved the reform's central premise — that opened acreage plus international risk capital would generate reserves Pemex alone would not — and then, through the Talos-Pemex unitisation dispute resolved by the AMLO administration in Pemex's favour in July 2021, became a symbol of the reversal instead. The electricity side delivered faster: three long-term clean-energy auctions (2015–2017) contracted approximately 7 GW of mostly solar and wind capacity at what were then world-record-low prices (the November 2017 solar average near 20.6 dollars per MWh).

4.2 What Did Not Materialise

Against these successes stood the indicator the public could see: production kept falling. National crude output declined from approximately 2.43 mb/d (2013) to approximately 1.93 mb/d (2018) — a decline driven by Cantarell's and Ku-Maloob-Zaap's geology and by Pemex's continuing capital compression, not by the reform, whose new contracts could not plausibly have reached production within the window [TBD-VERIFY: private-operator production by end-2018 was on the order of 50,000–85,000 b/d]. Realised investment by end-2018 was approximately 17 billion dollars of the 161 billion committed — normal for upstream deployment cadence, ruinous against the expectations the 2013 selling had set. The reform's authors had promised visible abundance on a political timeline while building a programme that could only deliver on a geological one. By the July 2018 election, the gap between promise and dashboard was the opposition's evidence-in-chief, and the defence — that the reform was working exactly as a fifteen-year programme should at year four — was true, unprovable, and politically worthless.

4.3 The Gasolinazo, January 2017

The reform's political bill arrived on 1 January 2017, when the staged liberalisation of gasoline prices — scheduled under the 2014 fiscal package and accelerated by the SHCP to limit the fiscal cost of the subsidy at post-2016 exchange rates — produced an overnight increase of approximately 14–20 per cent in maximum gasoline prices. The gasolinazo triggered the most serious social unrest of the Peña Nieto sexenio: highway blockades, fuel-station seizures, looting of stores across multiple states, several deaths, and over a thousand arrests in the first week [TBD-VERIFY: casualty figures range from 4 to 6 deaths; arrest figures ~1,500 in early-January reporting]. The proximate cause was fiscal-calendar management rather than the constitutional reform itself — administered prices had been raised repeatedly under the old regime too — but the political coding was instantaneous and irreversible: the reform that had promised cheaper energy had delivered the largest single fuel-price increase in living memory, while (as the huachicoleo crisis simultaneously revealed) Pemex's pipeline network haemorrhaged stolen fuel. Peña Nieto's approval fell to the low teens [TBD-VERIFY: January 2017 approval polling, commonly cited at 12–17%]. Eighteen months later, AMLO won 53 per cent of the presidential vote carrying a single, endlessly repeated energy promise: no more gasolinazos, and the restoration of Pemex. The gasolinazo is the hinge of the whole arc — the moment the 2013 decision lost the public argument it had never properly made.

5. The Reversal (2018–2024)

5.1 The Pausa: Suspension Without Abrogation

The reversal began within a week of AMLO's 1 December 2018 inauguration: on 7 December 2018, Sener and the CNH postponed the pending Ronda Cuatro bid deadlines, and across 2019 the postponement hardened into indefinite suspension of all new rounds and farm-outs. The design of the reversal's first phase is analytically important: AMLO did not send a repeal amendment (he lacked the two-thirds majority until 2024 and, after the failed 2014 consultation, framed his election itself as the mandate), did not abrogate the 107 existing contracts (he repeatedly threatened review for corruption, then honoured them — the BHP/Woodside Trion final investment decision of June 2023 proceeding under his government), and did not formally dismantle the regulators. The instrument was administrative: no new allocations, slow-walked permits, and the redirection of the state's fiscal and discursive resources into the restoration of the 1938 imaginary. AMLO's chosen term was the pausa — and its corollary was a production test he set publicly for the private contract holders, whose failure to lift output quickly became his standing justification for not resuming rounds.

The restoration programme had three monuments. First, the Dos Bocas refinery (Olmeca) in AMLO's home state of Tabasco — announced in 2019 against the advice of the SHCP's own cost-benefit analysis, budgeted at approximately 8 billion dollars, inaugurated symbolically on 1 July 2022, and ultimately costing roughly twice the budget [TBD-VERIFY: cumulative cost figures range ~16–20bn] while reaching meaningful throughput only years late — the physical embodiment of the doctrine that sovereignty meant refining one's own gasoline. Second, the Pemex fiscal rescue: successive reductions of the DUC (from 65 per cent toward 30 per cent by 2024 [TBD-VERIFY: rate path]), repeated capital injections, and debt-service support cumulatively in the 70–100 billion dollar range across the sexenio [TBD-VERIFY: cumulative support estimates vary with method] — a transfer that stabilised Pemex's debt stock near 100–110 billion dollars without restoring either production or reserve replacement. Third, the cancellation of the institutional complements: the clean-energy auctions were suspended, the Zama operatorship was awarded to Pemex over the discoverer Talos in July 2021, and the CNH and CRE were starved — vacancies left unfilled, then filled with loyalists; budgets cut; permit queues lengthened into de facto denial.

5.2 Electricity: The Frontal Assault and the One Defeat

The electricity sector, where the 2013 reform had worked best, drew the reversal's hardest measures. The May 2020 Sener reliability decree and then the 9 March 2021 Ley de la Industria Eléctrica amendments inverted the wholesale market's economic-merit dispatch in favour of CFE plants regardless of cost — striking directly at the private renewable generation the 2015–2017 auctions had contracted. The courts pushed back: injunctions suspended much of the 2021 LIE, and the SCJN's 7 April 2022 ruling on acción de inconstitucionalidad 64/2021 left the amendments in contested partial effect [TBD-VERIFY: the precise post-2022 enforceability of the LIE amendments was litigated amparo by amparo].

Blocked judicially, AMLO escalated constitutionally — and lost. The constitutional electricity initiative sent in October 2021 would have guaranteed CFE 54 per cent of generation, dissolved the CRE and CNH, cancelled the self-supply and independent-producer contracts, and subordinated the market to CFE as a single vertically reintegrated state entity. On 17 April 2022 — Easter Sunday, scheduled in the hope of opposition absences — the Chamber voted 275–223, fifty-nine votes short of the two-thirds threshold. It was the only major legislative defeat of AMLO's six years, delivered by a disciplined PRI-PAN-PRD-MC bloc that had campaigned under the va por México coalition's first and only fully successful veto. The consolation was immediate and deliberate: within days, AMLO's government passed by simple majority the mining-law amendment nationalising lithium (April 2022), creating the state company LitioMx by August 2022 — symbolically extending the Cárdenas template to the energy mineral of the coming century, whatever the commercial reality of Mexico's clay-hosted deposits.

The April 2022 defeat set the reversal's final logic. Unable to amend, the government governed against the 2013 framework administratively — what critics called regulatory strangulation: permits for private import, storage, and generation delayed or denied; CRE tariff and permit decisions aligned with CFE's commercial interest; inspections and closures deployed against private terminals. The strategy achieved much of the counter-reform's effect without its text — at the price of legal exposure under the USMCA.

5.3 The USMCA Consultations, July 2022

On 20 July 2022 the United States Trade Representative requested formal consultations under USMCA Chapter 31, alleging that the LIE dispatch preference, the permitting freeze, and measures favouring Pemex and CFE violated national-treatment and market-access commitments; Canada joined on 21 July (the trade-architecture context is treated in MX-B-04 and the Trump-2 escalation in MX-E-02). AMLO's response — delivered on 16 September — was to frame the dispute as a sovereignty question, complete with the rhetorical flourish that Mexico's energy policy was not negotiable. The consultations were never escalated to a panel: the Biden administration weighed the near-certain legal win against the migration and fentanyl cooperation it needed from AMLO and chose indefinite deferral, and the second Trump administration subsumed the energy file into its broader tariff confrontation (MX-E-02). But the unresolved consultations carried forward as a standing liability into the July 2026 joint review (MX-D-05, MX-D-06), where the energy chapter is among the US side's enumerated grievances [TBD-VERIFY: the formal status of the 2022 consultations and the energy file's placement in the 2026 review agenda]. The deeper point for the decision analysis: the 2013 reform's architects had deliberately hard-wired the opening into NAFTA's successor precisely to raise the cost of reversal — and the mechanism worked partially, constraining the reversal's form (no expropriations, contracts honoured) without preventing its substance.

5.4 What the Reversal Did Not Reverse

By the end of AMLO's term the de jure 2013 framework still stood: the constitutional text unamended, the contracts alive, the regulators formally autonomous. Production had continued to fall — approximately 1.55–1.65 mb/d by 2024, with private operators now contributing on the order of 110,000 b/d [TBD-VERIFY: 2024 private-operator share] — and Pemex's debt, supplier arrears, and single-digit-rated credit had become a permanent contingent liability of the sovereign. The reversal had succeeded politically (energy sovereignty polled as one of AMLO's most popular causes, and no gasolinazo recurred — fuel prices were smoothed by fiscal subsidy at multi-billion-dollar annual cost [TBD-VERIFY]) while failing on its own stated metric, the restoration of Pemex's productive capacity. It remained for the successor — armed with the supermajority AMLO never had until his final month — to decide whether to constitutionalise the reversal. She did.

6. The Sheinbaum Consolidation (2024–2026)

6.1 The October 2024 Constitutional Counter-Reform

The June 2024 election delivered what April 2022 had denied: a Morena-PT-PVEM supermajority in the Chamber and a near-supermajority in the Senate, completed by defections (MX-D-01). Within the Plan C constitutional programme that the outgoing AMLO and incoming Sheinbaum administrations executed jointly in September–November 2024 — alongside the judicial election reform and the welfare constitutionalisation (MX-G-02) — the energy counter-reform passed essentially without resistance. The amendments to Articles 25, 27, and 28, approved in October 2024 and published in the Diario Oficial on 31 October 2024 [TBD-VERIFY: promulgation date], redefined Pemex and CFE from empresas productivas del Estado — the 2013 settlement's commercial-governance category — to empresas públicas del Estado, entities whose constitutional purpose is the fulfilment of the state's social and strategic responsibilities rather than the generation of economic value. The amendment restored the principle of state prevalencia (primacy) in strategic energy activities: CFE was guaranteed the dominant share of electricity supply — codified in the secondary legislation at a 54 per cent floor of generation [TBD-VERIFY: the 54% figure appears in the March 2025 secondary laws; confirm codification form] — with private generation permitted in the remainder under state planning, and Pemex confirmed as the state's preferred upstream vehicle. The vote that had failed 275–223 in April 2022 passed in October 2024 by margins exceeding two-thirds in both chambers within weeks [TBD-VERIFY: precise vote counts], a measure of how completely the 2024 election had resolved the constitutional arithmetic.

The companion reform completed the institutional reversal: the November–December 2024 constitutional amendment dissolving the autonomous bodies (COFECE, IFT, INAI, and the energy regulators among them) eliminated the CNH and CRE as constitutionally autonomous organs, with the March 2025 secondary legislation absorbing their functions into a new Comisión Nacional de Energía (CNE) under Sener's coordination [TBD-VERIFY: details of the CNE's design and the CNH/CRE wind-down calendar]. The 2013 reform's institutional signature — round allocation and tariff regulation placed deliberately outside executive control — was thus erased not by neglect, as under AMLO, but by design. The new framework's eight secondary laws, published in March 2025, simultaneously created the instrument that defines the Sheinbaum settlement's distinctiveness: the desarrollos mixtos (mixed-development schemes), under which private capital may participate in upstream projects in minority association with Pemex — Pemex holding no less than 40 per cent and retaining strategic control [TBD-VERIFY: the minimum-participation calibration and the modalities of the mixed-contract framework] — together with continued private participation in generation, storage, and import under permit. The opening of 2013 was thus not closed but inverted: where the 2013 framework made the state one competitor within a market it regulated at arm's length, the 2025 framework makes private capital a minority partner within a state plan.

6.2 Plan México and the Investment Framing

Sheinbaum's presentation of the settlement differed sharply from AMLO's in register while preserving its substance. The January 2025 Plan México industrial strategy and the accompanying Plan Estratégico de Pemex 2025–2035 and CFE investment programme framed energy as the enabling infrastructure of nearshoring: a commitment to stabilise crude production at approximately 1.8 mb/d [TBD-VERIFY: the 1.8 mb/d target appears in the Pemex strategic plan; actual 2025 production ran below 1.65 mb/d], petrochemical and fertiliser recovery, approximately 13.6 billion dollars in announced mixed-scheme upstream projects [TBD-VERIFY], and a CFE expansion plan adding generation and transmission capacity of roughly 22–29 GW to 2030 [TBD-VERIFY: figures from the CFE 2025–2030 expansion programme]. The fiscal treatment of Pemex was systematised rather than improvised: the 2025 consolidation of the upstream fiscal regime into a single derecho petrolero para el bienestar [TBD-VERIFY: design details], continued amortisation support through vehicles including a multi-billion-dollar pre-capitalised investment fund [TBD-VERIFY: the 2025 Pemex funding vehicle, reported ~$12bn equivalent], and the explicit sovereign embrace of Pemex's debt service. The company's financial debt stood near 100 billion dollars with supplier arrears near 20 billion [TBD-VERIFY: 2025–2026 figures] — the permanent constraint within which every Mexican energy decision since 2013 has been taken, and which neither the opening nor the reversal has materially relieved.

6.3 The Renewables Paradox

The Sheinbaum consolidation contains the arc's most discussed irony: the climate scientist president — a PhD in energy engineering, a contributing author to IPCC assessment reports — inherited and constitutionalised a fossil-restoration project built around a refinery and a state oil company. Her adjustments are real but bounded, and the corpus line (MX-D-02, MX-D-05, MX-D-06) reads them as recalibration within the sovereignty settlement rather than departure from it: the resumption of large-scale renewable procurement through CFE-led and mixed schemes rather than the 2015-style private auctions; a stated goal of raising the clean share of generation toward 45 per cent by 2030 [TBD-VERIFY: target formulation in the Sener sectoral programme]; solar programmes including the Sonora-anchored public projects and distributed-generation expansion; and the cap-not-cut treatment of Pemex — production held at 1.8 mb/d for energy security rather than expanded for export [TBD-VERIFY: 2025–2026 policy statements and delivery against them]. Readings divide. The sympathetic reading: Sheinbaum is decarbonising the only way Mexican politics permits — through the state, at the pace the state's finances allow, without re-litigating sovereignty. The critical reading: the constitutional entrenchment of CFE's 54 per cent floor, the regulators' absorption, and the Pemex fiscal burden cap Mexico's energy transition at the speed of its slowest state enterprise, precisely as nearshoring demand makes reliable clean power the binding constraint on the industrial strategy (MX-D-05). Both readings agree on the structural fact: the energy-transition question in Mexico is now decided inside the state, which is exactly what the 2024–2025 counter-reform was designed to ensure.

7. The Paired Decisions in Analysis

7.1 What the 2013 Reform Got Wrong Politically

The 2013 reform failed politically before it could succeed economically, and the failure had identifiable design causes. First, the elite pact without social anchoring. The reform was negotiated among three party leaderships, passed in twenty-two days against the left's parliamentary resistance, and never submitted to the public argument its symbolic weight demanded — the SCJN's October 2014 consultation blockage completing the pattern. Its beneficiaries (future investors, future consumers of cheaper energy) were diffuse and prospective; its narrative enemies (foreign oil companies at the gates of the patrimony) were concentrated and mythically pre-loaded. No durable constituency was built to defend it: by 2018 the reform had contracts but no voters.

Second, the timing of the pain. The gasolinazo of January 2017 delivered the reform's costs to every household with a vehicle eighteen months before the election, while its benefits sat in committed-investment tables and undeveloped deepwater blocks. The sequencing was partly fiscal accident, but the underlying choice — promising consumer-price relief from a producer-side reform — was the architects' own.

Third, the corruption taint. Emilio Lozoya Austin — Peña Nieto's campaign aide and Pemex CEO 2012–2016 — was arrested in Spain in February 2020 and extradited in July 2020; his cooperation statements to the FGR alleged that Odebrecht money received through the 2012 campaign was used in part to bribe opposition legislators to support the structural reforms, the energy reform among them, naming PAN senators among the recipients [TBD-VERIFY: the Lozoya allegations remain judicially unresolved; the case's procedural status as of 2025–2026, including the Odebrecht and Agronitrogenados tracks, should be confirmed]. The allegations were never proven at trial, and their airing was itself an instrument of the AMLO government's politics; but they fused, in public memory, the reform's passage with the sexenio's broader corruption record — Odebrecht, the Casa Blanca affair, Agronitrogenados — and retroactively delegitimised the two-thirds majorities of December 2013. A constitutional change is only as durable as the perceived integrity of its enactment; the Lozoya confessions, whatever their ultimate judicial fate, stripped the 2013 amendment of that protection.

7.2 What the Reversal Cost Economically

The reversal's costs are of three kinds, each partially quantifiable. The investment freeze: no new upstream rounds after 2018 means the committed-investment pipeline stopped at approximately 161 billion dollars projected and a small realised fraction; the clean-energy auctions' suspension halted what had been among the world's cheapest renewable procurement; and total energy-sector FDI ran far below both the reform's projections and regional peers through 2019–2024 [TBD-VERIFY: comparative FDI figures]. The fiscal transfer: 70–100 billion dollars of Pemex support across the AMLO years [TBD-VERIFY], plus Dos Bocas's cost overrun and the ongoing fuel-price-smoothing subsidies — resources with measurable opportunity cost in a state whose tax take remains among the OECD's lowest and whose 2025–2026 fiscal consolidation (MX-D-05) has had to cut elsewhere. The friction costs: the USMCA consultations' standing liability, the arbitration exposure from disputes including Talos/Zama's aftermath [TBD-VERIFY: status of energy-sector investor-state claims], and — most consequentially for the 2025–2026 conjuncture — the energy-cost-and-reliability burden on the nearshoring strategy, in which industrial investors cite electricity availability and clean-power scarcity among the principal constraints on relocation to Mexico [TBD-VERIFY: survey evidence]. Against these costs the reversal's defenders enter real items: no gasolinazo recurred; energy prices to households were stabilised; sovereignty over the system was restored before the 2025–2026 trade confrontation made dependence dangerous; and the 2013 programme's own production promises had failed on their stated timeline. The ledger is genuinely mixed in politics even where it is lopsided in economics — which is the finding.

7.3 The Institutional Lesson: The Mexican Pendulum

Read as a pair, the two decisions teach a precise constitutional lesson: in a system where a single coalition can reach two-thirds, constitutional entrenchment without cross-bloc consensus is not entrenchment at all — it is a wager on never losing a supermajority election. The 2013 reformers amended the constitution against the organised left and lost the wager within eleven years. The 2024–2025 counter-reformers amended it back against the organised market — and their settlement is, in strict institutional terms, exactly as contingent, secured only so long as Morena's electoral dominance (MX-D-01, MX-D-04) holds. The contrast with the Chilean case is instructive: Chile's 1980 constitution entrenched its economic model behind supermajority locks so high that even two successive constituent processes (2022, 2023) failed to replace it, producing rigidity and frustrated reform; Mexico's 1917 constitution, amended more than 700 times, entrenches almost nothing against a determined supermajority, producing the pendulum — reform and counter-reform written successively into the same articles. Neither pole is obviously superior; but the Mexican energy arc shows the pendulum's specific cost: fifteen-to-thirty-five-year capital does not flow into five-year constitutional settlements, and both the 2013 opening and the 2025 desarrollos mixtos have had to price that discount.

The arc also clarifies what did bind. The contracts survived both presidents — protected by the USMCA's investment disciplines, by Pemex's need for partners (Trion's 2023 FID, the mixed schemes' explicit courtship of the same majors the rounds had brought), and by the reputational cost of expropriation that the 1938 precedent itself, paradoxically, taught Mexican governments to avoid repeating. The durable layer of the 2013 reform was not its constitutional text, which proved fully reversible, but its contractual and treaty layer, which proved sticky. Students of reform design should note the inversion: the instrument assumed strongest (constitutional amendment) was weakest, and the instruments assumed technical (contract law, trade treaty) carried the load.

7.4 Energy Sovereignty as the Common Language

The final analytical observation is the one with which the Key Takeaways closed: both decisions were argued in the same vocabulary. Peña Nieto promulgated the 2013 reform standing beside portraits of Cárdenas, insisting the hydrocarbons remained the Nation's and invoking Cárdenas's own 1940 contracting law; AMLO reversed it in Cárdenas's name; Sheinbaum constitutionalised the reversal as the recovery of what the neoliberal period had alienated. No major actor in the thirteen-year arc argued against energy sovereignty — they argued about its content: ownership versus operation, state-as-regulator versus state-as-operator, sovereignty-through-capacity versus sovereignty-through-control. This is the sense in which the 1938 settlement never decayed at all. Its operational core — Pemex's monopoly — decayed into the 2013 reform; its symbolic core proved strong enough to power the reversal; and any future re-opening, which Pemex's finances make less than hypothetical, will have to be argued in the same language. The cuarta transformación's energy politics (MX-C-02) are, on this reading, less an aberration from Mexico's modernisation than the reassertion of its oldest post-revolutionary constant.

8. Conclusion

Between December 2013 and March 2025, Mexico amended the constitutional core of its energy settlement twice, in opposite directions, each time by supermajority, each time invoking Lázaro Cárdenas. The 2013 decision was a technically sophisticated answer to a real problem — a national oil company in geological and financial decline, holding resources it could not develop — carried through an elite pact that could assemble two-thirds of Congress but not a third of public sentiment, sold on consumer promises it could not keep on a political timeline, and tainted in retrospect by the corruption allegations surrounding its passage. It produced genuine results — Zama, Trion, 107 contracts, world-record renewable prices — on a schedule its own politics could not survive. The 2019–2025 reversal was a politically sophisticated answer to the 2013 reform's political failure: administratively executed where amendment was unavailable, constitutionally completed when the 2024 supermajority arrived, popular throughout, and economically unable — on its own evidence through 2026 — to arrest the decline of the company in whose name it was conducted.

The natural experiment's result, as far as it can be read in 2026, is uncomfortable for both schools. The liberalisers were right that Pemex alone cannot reverse Mexico's production decline, and wrong that constitutional engineering plus international capital could be made politically self-sustaining without a domestic constituency. The nationalists were right that energy sovereignty is the only language in which Mexican energy policy can be durably legitimated, and wrong — so far — that state primacy plus fiscal transfusion can restore the productive capacity that legitimacy is supposed to protect. The Sheinbaum settlement of 2025–2026 — state prevalencia with subordinated private participation, a capped Pemex, a CFE-led transition, and roughly 100 billion dollars of debt standing permanent guard over every option [TBD-VERIFY] — is the synthesis the pendulum has currently produced. Whether it is an equilibrium or merely the pendulum's present position will be determined by the same three forces that drove both prior decisions: Pemex's geology, the federal balance sheet, and the next supermajority.

For the corpus, MX-K-02 pairs with MX-K-01 as the second study in how Mexican sexenio-scale decisions are made and unmade: where the Tequila-crisis arc shows a crisis decision producing durable institutions because its reforms (the 1996 electoral architecture) were negotiated across the whole spectrum, the energy arc shows the inverse — two constitutional decisions, each taken against a major bloc, each undone or contingent within a political generation. The comparison is the K-block's standing argument: in Mexico, how a decision is passed predicts its half-life better than what it contains.
