The US dollar traded at S/3.350 for purchases and S/3.375 for sales in Peru's parallel currency market on Saturday, September 12, 2026, according to the financial website cuantoestaeldolar.pe.
The figure was one of several exchange rates recorded in Peru that day, as commercial banks, the tax agency Sunat and the financial data provider Bloomberg each published their own reference prices for the US currency.
Exchange rate at Peru's banks
Peru's leading banks quoted a range of buy and sell prices for the dollar on Saturday. Banco de Credito del Peru (BCP), the country's largest bank by assets, offered S/3.525 for purchases and S/3.540 for sales. Interbank quoted S/3.493 to buy and S/3.576 to sell, while Banco de la Nacion, the state-owned bank, set its rate at S/3.480 for purchases and S/3.600 for sales.
BBVA, the Peruvian unit of the Spanish banking group, offered S/3.468 to buy and S/3.608 to sell. Scotiabank, the local arm of the Canadian lender, quoted S/3.519 for purchases and S/3.558 for sales.
Sunat and Bloomberg reference rates
The National Superintendency of Customs and Tax Administration, Sunat, which uses its own exchange rate to calculate customs duties and other levies, listed the dollar at S/3.363 for purchases and S/3.371 for sales on Saturday. Separately, Bloomberg reported that the exchange rate opened the day at S/3.3633.
What the buy and sell prices mean
The buy price is the amount a bank or exchange house pays to receive dollars from a customer, while the sell price is what it charges to hand dollars over. The difference between the two rates is known as the spread, and it can vary depending on the bank, exchange house or platform used.
Peru's currency, the sol, floats against the dollar and is tracked daily by consumers, importers and exporters. Sunat's official rate is widely used for customs and tax purposes, while bank and parallel-market rates reflect commercial supply and demand for dollars on a given day.
