I propose and test a new channel through which bank lending is affected in an emerging markets setting. This channel is that when banks arbitrage covered interest rate parity (CIP) deviations, they need to borrow in a particular currency. In the presence of borrowing frictions, they shift part of the resources used to lend to households and firms to fund their arbitrage activities. I exploit differences the abilities of Peruvian banks to arbitrage CIP deviations to show that banks that have greater ability to arbitrage reduce their lending in the currency they need to fund their CIP arbitrage. This is compensated by lending in a different currency. Therefore, arbitraging CIP deviations lead to changes in the currency composition of lending.
