The size and management of these reserves influence the confidence of investors and traders in the stability of a country's currency.

Many central banks follow inflation targeting as a key component of their monetary policy. By aiming for a specific inflation rate, central banks seek to create price stability. Changes in inflation rates can impact currency values, and central banks may adjust interest rates to maintain their inflation targets.
