Unstable exchange rates have forced countries 'central banks to make increasing use of interest rates to adjust and stabilize exchange rates: By raising interest rates they attract money into the country and so shore up the value of the currency, while by cutting interest rates they suppress rises in exchange value.
由於匯率不穩，為了調節匯率、避免暴升暴跌，各國央行又祭出利率為武器：藉提高利率、吸引資金流入來守住幣值，或是藉降低利率來抑止升值。
