Understanding RBI's Money Supply Measures

The Reserve Bank of India (RBI) plays a crucial role in managing the Indian economy, and one way it does this is by monitoring the money supply. Money supply refers to the total stock of money circulating in an economy at a specific point in time. The RBI publishes figures for different measures of money supply to understand the liquidity situation and help in formulating monetary policy.

Historically, the RBI has revised its measures of money supply. Currently, based on the recommendations of the Working Group on Money Supply (1998), the RBI publishes data on four measures of money supply. These measures are categorised based on their liquidity, ranging from the most liquid (M1) to the least liquid (M4).

Let's look at these four measures:

• M1 (Narrow Money): This is the most liquid measure. It includes currency held by the public, demand deposits with banks (savings and current accounts), and 'other deposits' with the RBI.
• M2: This measure is slightly less liquid than M1. It includes M1 plus savings deposits with post office savings banks.
• M3 (Broad Money): This is a broader measure of money supply. It includes M1 plus time deposits with banks (like Fixed Deposits and Recurring Deposits). M3 is the most commonly used measure of money supply.
• M4: This is the broadest measure. It includes M3 plus total deposits with the post office savings organisation (excluding National Savings Certificates). This is the least liquid of the four measures.

Here is a simple overview of the components:

Understanding these different measures helps economists and policymakers analyse the levels of liquidity in the economy and make informed decisions regarding monetary policy.

Additional Information on Money Supply

Besides M1, M2, M3, and M4, the RBI also tracks other liquidity aggregates. These include L1, L2, and L3, which are even broader measures of liquidity in the economy. They include components like term deposits with term lending institutions and refinancing institutions, term borrowing by these institutions, and certificates of deposit issued by financial institutions.

The different measures of money supply (M1, M2, M3, M4) are important indicators for understanding the monetary situation in India. Changes in these measures can indicate shifts in economic activity, inflation pressures, and the effectiveness of monetary policy actions taken by the RBI.

The current classification (M1, M2, M3, M4) was introduced following the recommendations of the Second Working Group on Money Supply, constituted in 1998. This framework is used to analyse and report monetary data regularly.
