Which policy instrument is most directly used to influence inflation and the cost of borrowing?

• A. Monetary policy; central bank actions on money supply and interest rates.
• B. Fiscal policy; tax and spending changes.
• C. Industrial policy; subsidies for sectors.
• D. Trade policy; tariff adjustments.

Answer: (A)

Monetary policy is the tool most directly used to influence inflation and the cost of borrowing because it directly controls the money supply and the interest rates that lenders charge and borrowers pay. By adjusting the policy rate and using instruments like open market operations or reserve requirements, the central bank shifts liquidity in the financial system. Lowering rates and expanding money supply makes borrowing cheaper, tends to boost demand, and can raise inflation. Raising rates and reducing liquidity makes borrowing more expensive, cools demand, and helps lower inflation. Fiscal policy, industrial policy, and trade policy influence inflation and borrowing costs only indirectly: taxes and government spending affect overall demand and deficits, while industry and trade measures affect prices through sectoral changes and competitiveness, but they don’t set credit conditions as directly as monetary policy. So the central bank’s actions on money supply and interest rates are the most direct way to target inflation and the cost of borrowing.
