What does the central bank do to conserve the foreign exchange reserves?

To conserve foreign exchange reserves, a central bank typically engages in careful management of its currency's exchange rate, often intervening in the foreign exchange market to stabilize the local currency. It may also implement monetary policies that promote economic stability, thereby reducing the need for foreign currency to stabilize trade balances. Additionally, the central bank can impose capital controls to manage the outflow of foreign currency and prioritize the use of reserves for essential imports and debt servicing.
