Twenty-two days after Peru's June 7 run-off, the Office of National Electoral Processes (ONPE), the body that tallies the country's votes, closed its count at 100%. Keiko Fujimori of Fuerza Popular finished with 50.135% (9,223,396 votes) against leftist Roberto Sánchez of Juntos por el Perú on 49.865% (9,173,755), a margin of just 49,641 votes.

The result conceals a sharper story for readers outside Peru. Within the country's borders, Fujimori lost by 32,014 votes. Her win was, in fact, manufactured abroad: Peru's expatriate diaspora handed her an 81,655-vote advantage, enough to flip the national result. The president-elect was put in office by citizens who do not live in the country she will run. 

It is Fujimori's fourth presidential bid, after three narrow losses since 2011. Her father, Alberto Fujimori, ruled Peru as an autocrat through the 1990s and was later convicted of crimes against humanity and corruption; his shadow has trailed her candidacies ever since. Under congressional majorities aligned with her party in recent years, courts and watchdog bodies seen as checks on executive power have been steadily reshaped, drawing criticism that Fuerza Popular has weakened, rather than strengthened, Peru's institutions.

Sánchez digs in, contests the result

Sánchez refuses to concede. He alleges a "fraude en desarrollo" (fraud in development), pointing to consulate tally sheets that, unlike in the first round, were not digitised before being shipped physically to Peru. He has filed an injunction, an acción de amparo, and signalled he will take his case to the inter-American human rights system.

A lawyer tied to a key Sánchez ally, the radical nationalist leader Antauro Humala, has separately sued to block Fujimori's proclamation until she formally renounces Japanese nationality, citing her father's use of a Japanese passport after fleeing Peru in 2000. The National Jury of Elections (JNE), Peru's top electoral court, is due to make its official proclamation by July 3.

Fujimori takes office with zero honeymoon. Her own remarks have acknowledged a country "practically divided." Fuerza Popular won outright in just nine of Peru's 25 regions.

An institutional fortress, and looming risks

Fujimori is not inheriting a standard executive presidency; she is stepping into an institutional fortress built to shield the ruling elite. A right-wing congressional coalition recently restored Peru's bicameral system, creating a super-Senate with sole power to appoint and impeach the heads of autonomous state bodies, from the constitutional court to the central bank, and which the president cannot dissolve under any circumstances.

Internationally, the result is being read as a relief. Markets and right-wing leaders, including Argentina's Javier Milei, have welcomed an outcome that locks in stability for major foreign assets, among them the Chinese state-controlled Chancay megaport and the US-Peru F-16 fighter jet deal. OAS Secretary-General Albert Ramdin has already spoken with Fujimori and is due to attend her July 28 inauguration.

But domestically, the picture is bleaker. Fujimori faces a hostile Andean south that voted overwhelmingly for Sánchez, and the World Meteorological Organization (WMO) puts the odds of a severe El Niño event by southern-hemisphere summer at 60%, a threat to the coastal infrastructure her investment agenda depends on.

Fujimori's win extends a rightward shift that has now reached South America's largest economies within a single year. Milei set the template in Argentina back in 2023; José Antonio Kast's victory in Chile's December run-off and Abelardo de la Espriella's narrow triumph in Colombia's election this month have reinforced it, each welcomed by investors and fellow conservatives as further evidence that the region's "pink tide" is receding. Peru's result fits that pattern rather than breaking it: a market-friendly conservative narrowly prevailing over a fractured left, propped up by an institutional architecture designed to outlast her.

The difference is that Fujimori takes office having lost the vote of the country she will govern, and won it only abroad. Whether a presidency built that way can command authority at home, rather than merely reassurance in Washington and on trading floors, is the question Peru now has five years to answer.
