What does sterilization aim to achieve in macroeconomic policy?

• A. To enhance the banking sector's profit margins
• B. To stabilize the economy after an economic event
• C. To increase governmental revenue
• D. To promote higher national savings rates

Answer: (B)

Sterilization in macroeconomic policy refers to the action taken by central banks to neutralize the effect of foreign exchange interventions on the money supply. When a central bank engages in foreign exchange operations, such as buying or selling currency to influence exchange rates, it can inadvertently affect the domestic money supply. Sterilization aims to counter those effects to maintain control over inflation and interest rates.

By implementing sterilization measures, a central bank can stabilize the economy after an economic event. For example, if a central bank sells foreign reserves to support the domestic currency, it must absorb the resulting liquidity in the domestic market to prevent an increase in the money supply, which could lead to inflation. This stabilization can help ensure that the broader economy remains balanced and can recover more effectively from shocks or fluctuations, ultimately aiming for a stable economic environment conducive to growth.

In contrast, enhancing banking sector profit margins, increasing governmental revenue, or promoting higher national savings rates do not directly relate to the objectives of sterilization. These aspects focus on other areas of economic policy or financial sector performance, rather than the immediate goal of moderating currency volatility and maintaining monetary control through sterilization.
