### Definition

A base rate, in the context of finance and banking, refers to a benchmark interest rate that serves as a reference point for determining the interest rates on various financial products.

### What is a base rate?

Central banks or monetary authorities typically set the base rate as a tool to influence economic conditions, particularly to control inflation.

The base rate is often set by a country’s central bank. Central banks use the base rate as a monetary policy tool to regulate borrowing costs and money supply in the economy. The interest rates on loans and other financial products are commonly linked to the base rate. When the base rate changes, financial institutions adjust their interest rates accordingly. For example, a rise in the base rate may lead to higher borrowing costs for consumers and businesses.

The base rate also affects interest rates on savings accounts and other interest-bearing deposits. When the base rate increases, savers may see higher returns on their deposits, while a decrease in the base rate could result in lower interest earnings.

Changes in the base rate are often seen as indicators of the central bank’s stance on monetary policy. A higher base rate may indicate a desire to lower inflationary pressures, while a lower base rate is typically employed to stimulate economic activity and lending. Central banks periodically review and adjust the base rate based on economic conditions, inflation targets, and other relevant factors. These adjustments are communicated to the public and financial institutions.

### Example of base rate

A commercial bank, XYZ Bank, decides to offer a loan to a customer. It may determine the interest rate for the loan by adding a margin to the central bank’s base rate. Suppose XYZ Bank adds a margin of 2% to the base rate.

• XYZ Bankâ€™s lending rate = Central bank base rate + margin
• XYZ Bank’s lending rate = 3% = 2% = 5%

Therefore, XYZ Bank offers the loan to the customer with an interest rate of 5%, where 3% represents the central bank’s base rate, and 2% is the bank’s margin.
