In the monetary policy transmission mechanism, what effect does lowering the cash rate typically have?

• A. It reduces borrowing costs and stimulates spending and investment.
• B. It immediately decreases unemployment rates.
• C. It directly changes government tax revenue.
• D. It increases the exchange rate.

Answer: (A)

Lowering the cash rate works by easing the cost of borrowing. When the central bank lowers this rate, banks typically reduce their lending rates, making loans for homes, cars, and business investments cheaper. With cheaper credit, households are more likely to spend and firms are more likely to invest, boosting overall demand in the economy. This can lift production and push inflation toward a higher target over time.

Other channels can reinforce the effect: lower rates can raise asset prices and improve confidence, and a weaker currency from lower rates can make exports more competitive abroad. But the impact on unemployment isn’t immediate—the job market responds with lags as firms adjust hiring to new levels of demand. Monetary policy also doesn’t directly change government tax revenue, which is a fiscal matter. And lowering the rate usually doesn't push the exchange rate up; it tends to weaken the domestic currency.
