USDCHF USD/CHF is the currency pair that represents the exchange rate between the U.S. dollar (USD) and the Swiss franc (CHF). It shows how many Swiss francs are needed to buy one U.S. dollar. This pair is often influenced by U.S. and Swiss economic data, interest rate policies, and global risk sentiment. The Swiss franc is considered a safe-haven currency, meaning USD/CHF tends to decline in times of market uncertainty and rise when risk appetite increases.
