A central bank cuts its policy rate. Which sequence best describes the interest-rate channel of the transmission mechanism that follows?

The correct sequence is lower market and lending rates, cheaper borrowing, more consumption and investment, and therefore higher aggregate demand. A rate cut reduces the cost of credit and the reward for saving, so interest-sensitive spending expands. The alternatives describe tightening effects or fiscal channels unrelated to the rate cut.

  1. ALower money market and bank lending rates, cheaper borrowing for firms and households, higher consumption and investment, higher aggregate demandCorrect
  2. BHigher bank deposit rates, greater saving, lower consumption, lower aggregate demand
  3. CLower government spending, smaller budget deficit, lower aggregate demand
  4. DAppreciating currency, cheaper imports, lower net exports, lower aggregate demand
  5. Higher reserve requirements, reduced lending, lower investment, lower aggregate demand

Explanation

A policy rate cut lowers short-term market rates and then bank lending rates. Cheaper credit raises interest-sensitive spending such as business investment, housing and durable goods, increasing aggregate demand. The other options describe contractionary effects or are unrelated to a rate cut.
