US dollar rises to 3.361 soles in Peru

The US dollar closed at 3.361 Peruvian soles on Friday, September 18, 2026, rising from the previous interbank close of 3.358 soles. The US Dollar Index (DXY) rose 0.07% to around 100.23 points as global markets adopted a defensive stance.

Jorge Luis Huayta, FX trader at Kambista, stated that US Treasury yields resumed their upward path following the Federal Reserve's recent interest-rate decision. The 10-year Treasury yield rose 6.5 basis points to 5.004%, while the 30-year yield gained 4.6 basis points to 5.336%.

In commodities, WTI crude oil fell 6.30% to 95.49 dollars per barrel, marking its third consecutive decline. Gold rose 0.92% to 4,380 dollars per ounce, silver advanced 1.90% to 66.42 dollars per ounce, and copper climbed 1.28% to 6.72 dollars per pound.

In the local market, the Central Reserve Bank of Peru (BCR) did not roll over an expiring foreign-exchange swap of 500 million soles, creating indirect supply. Dollar sales from companies paying monthly taxes to Sunat also helped temper exchange-rate pressures. Huayta noted that the estimated economic impact of the El Niño phenomenon on GDP increased from -0.7% to -0.9%, affecting agro-exports, fishing, and hydrocarbons. Peru's September inflation data is expected on October 1, projected at 0.30% monthly and 4.70% annually, ahead of the BCR interest rate decision scheduled for October 7.
