Peruvian currency and international reserves trends

In mid-August 2026, the Peruvian sol demonstrated strength against the US dollar. During this period, exchange rates varied across different sectors, with the informal parallel market quoting the dollar at approximately S/3.35 for purchase and S/3.37 for sale, while official Sunat reference rates were slightly higher. Major commercial banks, such as Banco de Crédito del Perú, maintained significantly higher rates and wider spreads than the parallel market.

By late August 2026, Peru’s net international reserves reached US$99.094 billion, approaching the US$100 billion milestone and suggesting a potential reversal of a downward trend that began in 2021. In the foreign exchange market, the parallel market rate saw a slight decrease, trading at 3.340 soles for purchases and 3.360 soles for sales, while official Sunat reference rates remained near 3.342 and 3.356 soles respectively. Commercial bank rates continued to remain higher than both official and parallel market quotations.

As of August 28, 2026, the Central Reserve Bank of Peru reported an official closing exchange rate of 3.358 soles. Commercial institutions maintained higher rates; for example, Banco de Crédito del Perú listed a buying price of 3.525 soles and a selling price of 3.540 soles.

During the first ten days of September 2026, the US dollar exhibited slight fluctuations but maintained relative stability. On September 8, the Superintendencia de Banca, Seguros y AFP (SBS) recorded average rates of S/3.351 for purchases and S/3.360 for sales. The parallel market on September 9 showed a purchase price of S/3.340 and a sale price of S/3.365. By September 10, SUNAT reported a purchase price of S/3.355 and a sale price of S/3.362. Throughout this period, purchase values fluctuated between S/3.351 and S/3.360, while sale prices moved between S/3.360 and S/3.372.
