The outcome of Peru’s presidential election remained unresolved on Monday, with both leading candidates claiming victory in a contest that has exposed deep political divisions and raised concerns over the security of British investments in the country’s mining and energy sectors.
With 95% of votes counted, nationalist candidate Marco Arana held a narrow lead over centrist economist Julio Guzmán, separated by less than one percentage point. The electoral authority has yet to declare a winner, citing a backlog of votes from rural and overseas districts. Final results are not expected before Wednesday.
The deadlock has triggered volatility on the Lima Stock Exchange, where the benchmark index fell 4% on Monday. The Peruvian sol weakened against the dollar for the third consecutive day. Bond yields rose, reflecting investor unease over potential policy shifts under either candidate.
Arana, a former environmental activist, has pledged to renegotiate contracts with foreign mining companies, increase state control over natural resources, and raise taxes on extractive industries. British firms, including Anglo American and BHP, hold substantial assets in Peru’s copper and gold mines. Guzmán, a former finance minister, has proposed gradual reform and fiscal discipline. He has sought to reassure investors, promising to maintain existing contracts and respect the independence of the central bank.
“The risk of a Arana victory is that it could lead to a wave of resource nationalism,” said Fiona Davenport, Latin America analyst at Control Risks. “British companies are particularly exposed given the concentration of UK investment in mining. Any disruption to operations would have significant repercussions for their shareholders and for Peruvian government revenues.”
Peru is the world’s second-largest copper producer. The mining sector accounts for 10% of GDP and 60% of export earnings. British investment in Peru has grown steadily since the signing of a free trade agreement between the UK and the Andean Community in 2020. The UK is now the fifth-largest foreign investor in Peru, with total assets exceeding £4 billion.
The political uncertainty has also delayed the passage of a long-awaited mining royalty bill, which the government had hoped to finalise before the election. The bill, which seeks to increase fiscal revenues from mining, has been opposed by industry groups who argue it would deter investment.
British diplomats in Lima have been monitoring the situation closely. The Foreign Office has issued a statement urging all parties to respect the electoral process and avoid violence. Protests have been reported in several cities, but no major incidents have been confirmed.
The new president will take office in August, at a time of economic strain. Peru’s economy contracted by 11% in 2020 due to the pandemic. The International Monetary Fund has warned that policy instability could derail recovery.
“Peru has a strong track record of macroeconomic stability, but this election is testing that reputation,” noted James Buckley, senior sovereign analyst at Moody’s. “Investors are looking for clarity and continuity. The longer the delay, the greater the risk of capital flight and a downgrade in Peru’s credit rating.”
Both candidates have called for calm, but their rhetoric remains combative. Arana accused Guzmán of representing “corrupt elites”, while Guzmán warned of “economic ruin under a radical regime”. The electoral authority has urged candidates to refrain from declaring victory prematurely. Recounts are possible if the margin falls within the legal threshold.
For now, British businesses operate in a state of suspended animation. Project expansions are on hold. New investment decisions are deferred. The cost of political uncertainty is rising by the day.
