Peru Mining Under Boluarte: Political Risk Through the 2026 Election Cycle

Boluarte as a holding pattern #

Dina Boluarte assumed the presidency on 7 December 2022 under Article 115 of the Peruvian Constitution after Congress impeached Pedro Castillo for attempting to dissolve the legislature. She inherited a five year term that runs through 28 July 2026 and a constitutional architecture in which the presidency is structurally weak. Article 117 limits criminal prosecution of a sitting president to a narrow set of charges, while Article 113 sets out the grounds for vacancia, including the open ended permanent moral or physical incapacity clause that Congress has invoked three times since 2017 to remove or threaten to remove a head of state.

Boluarte's approval has hovered between 4 and 8 percent through 2024 and 2025 in IEP and Ipsos tracking, the lowest sustained reading for any Peruvian president since polling began. The paradox is that she has survived. A Congress fragmented across more than ten parties has rejected every formal vacancia motion against her because no plausible successor commands a working majority and early elections would dissolve the current legislature. The result is a de facto pact: the executive does not push reform, the legislature does not push removal, and neither side controls the street. For the mining sector this equilibrium has been useful. The 2011 royalty regime, the special mining tax stack, and the IGV input refund mechanism have all remained intact across six prime ministers and four energy and mines ministers. What the equilibrium has not delivered is permitting throughput, conflict resolution capacity, or any meaningful response to illegal mining.

The 2022 to 2023 protest cycle and its sediment #

The protest wave following Castillo's removal killed at least 49 civilians and one police officer between December 2022 and March 2023, concentrated in Ayacucho, Apurimac, Cusco, Puno, and Arequipa. The Ombudsman and the Inter American Commission on Human Rights have documented the cases. No senior official has been convicted, criminal investigations remain open at the Fiscalia de la Nacion, and Boluarte herself has been named in preliminary inquiries that Article 117 currently shields from indictment. The protests crippled mining logistics for roughly eleven weeks. Las Bambas suspended from late January through early March 2023, Antapaccay halted multiple times, and the southern corridor from Apurimac and Cusco to the port of Matarani was blockaded at more than 100 points. MINEM later estimated lost output at roughly 90 thousand tonnes of contained copper, with concentrate stockpiles at Matarani and alternative routing through Ilo absorbing most of the gap.

The political sediment matters more than the lost tonnes. Communities along the Apurimac corridor learned that a sustained blockade can extract concessions, including the 2024 Las Bambas community fund expansion and renegotiated road use agreements with eleven of the 75 communities. Operators learned that the central government has limited capacity to clear corridors when the National Police is overstretched. The 2026 candidate field has been calibrated by both lessons.

Las Bambas, Quellaveco, and the next pipeline #

Las Bambas, owned by MMG, produced 322 thousand tonnes in 2024 against a nameplate range of 380 to 420. The 2024 reopening followed a community agreement that raised annual social spend, formalized truck routing windows, and committed to negotiate the long discussed mine life extension into the Chalcobamba pit. Chalcobamba is the single most important mining decision pending before SENACE and is unlikely to be resolved before the new administration takes office on 28 July 2026. Quellaveco, Anglo American's USD 5.5 billion Moquegua operation, completed its ramp through 2023 and 2024 and now runs near nameplate at roughly 320 thousand tonnes per year. It is the only large new copper mine commissioned in Peru since Las Bambas, and its operation in a region with comparatively constructive community relations is the case that next pipeline projects must replicate.

The pipeline itself is shallow. Tia Maria, Southern Copper's USD 1.4 billion Arequipa project, has held an approved EIA since 2014 but has never broken ground because of community opposition that turned violent in 2015 and 2019. Conga, Newmont's Cajamarca project, has been frozen since 2016 and is no longer carried as an active asset. Yanacocha, Newmont's gold operation, is transitioning to a sulfide ore body that requires roughly USD 2 billion of incremental capital, a decision the company has deferred multiple times. Antamina is in the late stages of a mine life extension whose final permits depend on the same SENACE queue holding up Chalcobamba. Cerro Verde is the volume base and faces water permitting questions that are slow but tractable.

The fiscal stack and the comparison with Chile #

Peru taxes mining through a layered structure. Corporate income tax sits at 29.5 percent. The regalia minera, recalibrated in 2011 from the prior contract regime, applies a sliding scale of 1 to 12 percent on operating margin. The Impuesto Especial a la Mineria adds a 2 to 8.4 percent margin scale for operations without legal stability agreements, while the Gravamen Especial a la Mineria covers stability agreement operators at 4 to 13.12 percent. The IGV at 18 percent applies to inputs and is recoverable on exports. Total government take runs at roughly 40 to 47 percent of operating margin at copper prices above USD 4 per pound.

Chile, by comparison, moved through a 2023 reform that introduced an ad valorem royalty plus a margin component, with combined government take projected by the IMF and Cochilco at 44 to 50 percent for large operators. Mexico, Indonesia, and the Democratic Republic of Congo cluster wider, between 35 and 55 percent depending on contract specifics. Peru therefore sits in the competitive middle of the comparator set, and the candidate field for 2026 has so far avoided concrete proposals to push the regime higher. Stability agreements remain a strategic asset. Operators that secured them under the 1990s regime, including Cerro Verde and Toromocho, retain a regulatory hedge against future reform, and the next administration's posture on negotiating new agreements will be the first signal of how investor friendly or investor neutral the post Boluarte settlement turns out to be.

SENACE, water, and the permitting bottleneck #

SENACE, the Servicio Nacional de Certificacion Ambiental para las Inversiones Sostenibles, certifies environmental impact assessments for major projects. Processing times for detailed mining EIAs have lengthened from roughly 14 months in 2018 to over 24 months by 2025, with several Las Bambas and Antamina modifications running past 30. The bottleneck reflects both technical capacity gaps and political caution: approving a permit that triggers a community blockade is more costly to the bureaucracy than letting the file age.

Water permitting, administered by the ANA under the Ministry of Agriculture, is the second binding constraint. The Cerro Verde dispute with the Arequipa regional government, the Cuajone bypass system after the 2022 Moquegua valley blockade, and the Antamina San Marcos negotiation all illustrate that water rights in the southern Andes are now the most contested resource for any expansion case. With glacier mass in the Cordillera Blanca down close to 50 percent since 1980 on INAIGEM and IRD measurements, water sharing agreements settled in the 2000s are open for renegotiation. The next administration will inherit roughly 25 active EIA modifications and four major new project files at SENACE. The throughput rate determines whether 2027 and 2028 production approaches 2.95 million tonnes or stalls below 2.7 million. Boluarte's MEF and MINEM have not pushed an emergency permitting decree, and there is no realistic legislative path to one before the election.

Illegal mining, Madre de Dios, and the sol #

Illegal artisanal mining in Madre de Dios produces roughly 30 to 40 tonnes of gold annually on Ministry estimates, more than the legal artisanal sector. It drives mercury contamination of the Madre de Dios and Inambari rivers, deforestation that MAAP and Conservacion Amazonica satellite tracking documents at roughly 25 thousand hectares per year, and a parallel financial economy the SBS and UIF have repeatedly flagged. Boluarte's Operativo Mercurio interdictions have been sporadic and have not altered the incentive structure.

The macro frame is steadier. The Peruvian sol has been the strongest emerging market currency in Latin America under BCRP president Julio Velarde and long tenured technical leadership including Adrian Armas. Reserves at roughly USD 78 billion, an inflation track record inside the 1 to 3 percent target band, and a flexible exchange rate regime together deliver ten year sovereign yields below comparator Brazil and Colombia. BCRP independence remains the most credible institutional anchor in the country. The risk is that a populist successor pressures the BCRP through board nominations, since the seven member board is appointed by the executive and confirmed by Congress, or through fiscal dominance via off budget transfers from FONAFE entities. None of the leading candidates has explicitly proposed either path, but the late 1980s record and the 2021 to 2022 Castillo cabinet remain tail risks that markets will price as the campaign sharpens.

April 2026, June 2026, and the post Boluarte settlement #

Peruvians vote on 12 April 2026 in the first round, with a runoff on 7 June 2026 if no candidate clears 50 percent. The field is wide and unstable. Rafael Belaunde Llosa, a right of center institutional reformer, polls in the low double digits. Martin Vizcarra, the former president whose disqualification was lifted by the JNE in late 2025, has reentered the race and consolidates centrist anti establishment voters. Rafael Lopez Aliaga, the Lima mayor on the populist right, leads in some Lima centric polls but performs weakly in the southern Andes. Veronika Mendoza of Nuevo Peru anchors the left and inherits the Castillo voter base on a platform that proposes royalty regime review and a constituent assembly. Keiko Fujimori of Fuerza Popular is testing a fourth candidacy. Several regional governors and former ministers fill out the first round.

The runoff matters more than the first round. A Mendoza versus Lopez Aliaga or Mendoza versus Belaunde matchup frames the vote as a referendum on the mining fiscal regime and the constitutional order. A Vizcarra versus Lopez Aliaga matchup defers the substantive policy question and concentrates the campaign on corruption and institutional reform. Castillo, in pretrial detention on rebellion and conspiracy charges, is constitutionally barred from running and his Peru Libre party is unlikely to clear the electoral threshold without a unifying figure.

Across plausible runoff outcomes, the central scenario for the mining sector is continuity. The royalty and special tax stack survives because no Congress assembled out of the April first round will deliver the votes to change it within the first 18 months. SENACE throughput improves marginally as a new administration appoints fresh leadership, Las Bambas Chalcobamba is approved by mid 2027, and Tia Maria remains frozen. The downside scenario, at roughly 25 percent probability, has Mendoza winning the runoff, calling a constituent assembly referendum within the first year, and triggering a 12 to 18 month regime uncertainty during which capital decisions on Yanacocha sulfide, Antamina extension, and the Las Bambas pipeline are deferred. The upside scenario, at roughly 20 percent probability, has Belaunde or a similar institutionalist winning, clearing the SENACE backlog and allowing Tia Maria on revised community terms.
