1. Hedging: Commercial banks can use foreign exchange derivatives to reduce exchange rate risk. Hedging refers to hedging positions with potential foreign exchange exposure to protect the interests of commercial banks.

2. Actively manage exposure: Commercial banks can reduce exchange rate risk by actively managing exposure. For example, commercial banks can adjust their balance sheets, adjust the amount of foreign currency on the balance sheet to a more suitable currency, or choose a more stable currency for investment.

3. Diversified investment: Commercial banks can reduce exchange rate risk through diversified investment. For example, commercial banks can invest their funds in foreign exchange derivatives to avoid excessive risk of a single asset portfolio.
