Solution:Bank Rate implies the rate of interest at which the RBI discount the Bills of Exchange. In other words, it is the rate of interest at which RBI provides loans to the commercial banks. It is an instrument of monetary policy to influence money supply in the economy.The concept of the bank rate may vary in different economies based on monetary policy frameworks. Here are some variations:
1. Nominal Bank Rate: This is the stated rate of interest inflation into account. It reflects the without taking percentage at which banks borrow from the central bank, unaffected by inflationary pressures
2. Effective Bank Rate: The effective bank rate reflects the actual cost of borrowing for commercial banks, taking into account compounding effects and other hidden costs.
3. Discount Rate: In some countries, particularly the United States, the term "discount rate" is used in a similar context. The Federal Reserve lends to banks at the discount rate. Although different from the bank rate in a technical sense, both have similar functions of influencing monetary policy.
4. Penal Rate: Sometimes, a higher rate than the standard bank rate is applied to banks when they borrow beyond a prescribed limit or fail to maintain required reserves. This is known as the penal rate.
