Peru Election 2026: Keiko Fujimori Wins Runoff and Takes Office
Peru: Election Watch
Key Facts
—Result. Keiko Fujimori won Peru’s June 7, 2026 presidential runoff with 50.135% (9,223,396 votes) against leftist Roberto Sánchez’s 49.865% (9,173,755 votes), per ONPE’s final count on June 29. The JNE proclaimed her president-elect on July 3, and she was sworn in on July 28.
—Congress. Peru’s Congress is bicameral again in 2026, with 130 deputies and 60 senators. Popular Force won 41 deputies and 22 senators, and together with its ally Popular Renovation it will hold about half the Senate seats — enough to shield Fujimori from removal attempts.
—Economy. Peru’s GDP grew 1.9% year-on-year in Q2 2026, according to the Central Reserve Bank (BCRP). Copper production fell 3.1% in the same period due to protests at the Las Bambas mine. The sol weakened 4.2% against the dollar in the first half of 2026.
—Corruption cases. Dina Boluarte was removed by Congress in October 2025 and remains under investigation for illicit enrichment. Interim presidents José Jerí and José María Balcázar bridged the gap to Fujimori’s inauguration. Pedro Castillo remains in pre-trial detention on rebellion charges.
—Mining. Peru is the world’s second-largest copper producer. Las Bambas (MMG/China) and Antamina (Glencore/BHP) account for roughly 35% of national output. Community protests over royalties and environmental damage have disrupted operations at both mines since 2022.
Keiko Fujimori’s razor-thin victory in Peru’s June 2026 runoff — and her swearing-in on July 28 — restored her family to the presidency three decades after her father’s authoritarian rule. She now faces a divided country, a slowing economy, and unresolved corruption cases that could test her government from day one.
The Election: How Fujimori Won by Fewer Than 50,000 Votes
Peru’s June 7, 2026, presidential runoff was the closest in the country’s modern history. Keiko Fujimori received 50.135% of the vote (9,223,396) against Roberto Sánchez’s 49.865% (9,173,755), a margin of just 49,641 votes. The National Office of Electoral Processes (ONPE) completed its count on June 29 after weeks of reviewing contested tally sheets, and the National Elections Jury (JNE) proclaimed Fujimori president-elect on July 3.
Sánchez, a leftist senator and close ally of imprisoned former president Pedro Castillo, contested the result, alleging irregularities in votes counted at Peruvian consulates abroad. Electoral authorities dismissed his complaints, and international observers reported no systemic irregularities. Sánchez nonetheless said he would not recognize a Fujimori government and led marches in Lima to “defend the vote.”
The geography of the vote was starkly divided. Fujimori won Lima, the northern cities, and the vote of Peruvians abroad, where middle-class voters responded to her promises of order and economic stability. Sánchez dominated the rural Andean highlands and the south, including Arequipa, Cusco, and Huancayo, where voters backed his left-wing platform. The split mirrors a deeper fracture in Peruvian society: between the formal, urban coast and the poorer, largely Indigenous interior.
Congressional Arithmetic: Power Without a Mandate
Peru returned to a bicameral legislature in 2026: 130 deputies and 60 senators. Fujimori’s Popular Force won 41 deputy seats and 22 Senate seats, making it the largest bloc in both chambers. Together with its ally Popular Renovation, it will hold about half the Senate seats once the new legislature is installed — a buffer that makes it far harder for opponents to remove her, the fate that befell several of her predecessors.
This arithmetic matters because Peru’s Congress has a recent history of removing presidents. Since 2018, Peru has burned through presidents at a rate of nearly one a year: Kuczynski resigned in 2018, Vizcarra was removed in 2020, Castillo in 2022, Boluarte in October 2025, and interim president José Jerí in February 2026 — after which Congress installed José María Balcázar as caretaker until Fujimori’s inauguration. Fujimori is the country’s tenth president in a decade. Her Senate cushion protects her only as long as she keeps her allies happy; any defection on mining policy, corruption investigations, or social spending could leave her vulnerable.
The opposition is fragmented. Sánchez’s allies and the parties linked to Castillo underperformed in the congressional vote, and a collection of regional parties and independents holds the balance. These groups have little in common but share a suspicion of Fujimori, whose father’s presidency (1990–2000) was marked by authoritarianism, corruption, and human rights abuses.
The Corruption Shadow: Castillo, Boluarte, and the Judiciary
Fujimori’s presidency is shadowed by unresolved corruption cases against her predecessors. Former president Pedro Castillo, who was impeached and arrested in December 2022 after attempting to dissolve Congress, remains in pre-trial detention on charges of rebellion and conspiracy. His trial, which began in March 2025, has been delayed repeatedly by defense motions. If convicted, he faces up to 20 years in prison.
More politically explosive is the case of Dina Boluarte, Castillo’s vice president, who succeeded him and was herself removed by Congress in October 2025 amid a crime wave and rock-bottom approval ratings. She remains under investigation by the Attorney General’s Office over alleged illicit enrichment, including undeclared luxury watches and jewelry. Boluarte denies wrongdoing and argues the investigations are politically motivated.
The cases matter for Fujimori because they set the tone for how her government will handle corruption. If she pushes for aggressive prosecution of Boluarte and Castillo, she risks being seen as vindictive. If she slows the investigations, she risks being accused of covering up for allies. Her father, Alberto Fujimori, was himself convicted of human rights abuses and corruption in 2009; he was released in December 2023 and died in September 2024, a legacy that complicates any position she takes on judicial independence.
The Copper Problem: Mining, Protests, and Fiscal Pressure
Peru’s economy is fundamentally a mining economy. The country is the world’s second-largest copper producer, behind Chile, and mining accounts for roughly 60% of export earnings and 15% of government revenue. The Central Reserve Bank (BCRP) reported GDP growth of 1.9% year-on-year in Q2 2026, but the figure masks significant sectoral divergence: agriculture and services grew, while mining contracted.
The contraction was driven by protests. Community groups near the Las Bambas mine (operated by China’s MMG) and the Antamina mine (joint venture between Glencore and BHP) have repeatedly blocked roads and occupied facilities, demanding higher royalty payments and stricter environmental controls. Las Bambas alone lost an estimated 45 days of production in the first half of 2026, equivalent to roughly 120,000 tonnes of copper.
The protests are not new — they have been ongoing since 2022 — but they have intensified as global copper prices have risen. When copper trades above US$9,000 per tonne, as it has for most of 2026, the incentive for communities to demand a larger share increases. Fujimori has promised to negotiate new “social licenses” for mining projects, but any increase in royalties or community payments will reduce the government’s fiscal take and could deter new investment.
The Currency and the Fiscal Squeeze
The Peruvian sol has weakened 4.2% against the US dollar in the first half of 2026, according to BCRP data. The depreciation reflects multiple pressures: lower copper exports, political uncertainty, and the Central Bank’s decision to cut interest rates from 6.0% to 5.25% between January and June 2026 to support growth. The weaker sol increases the local-currency cost of imported goods, particularly fuel and food, which has fueled inflation that reached 3.4% in June — above the BCRP’s 1–3% target range.
Fujimori faces a fiscal bind. Peru’s public debt is relatively low at roughly 35% of GDP, but the government’s ability to borrow is constrained by political risk premiums. Any attempt to increase social spending to address the protests will require either higher taxes — politically difficult — or deficit financing, which could trigger a credit rating downgrade. Moody’s currently rates Peru at Baa1 with a stable outlook, but it has warned that “persistent social unrest and policy uncertainty” are key downside risks.
