Minimum reserve system
Also called: MRS · Topic: Money: From Barter to Digital Currency · NCERT: Beyond NCERT
Meaning
The minimum reserve system is the rule that decides what backing India's currency notes need. Under it, the RBI must hold at least ₹200 crore of gold and foreign assets. At least ₹115 crore of this must be gold. India adopted it in 1956-57. Once this fixed floor is met, the RBI can issue notes without any further link to its gold stock.
Example
Under the older rule, a rise in note issue meant the RBI had to add more gold or sterling backing. Under the minimum reserve system, the ₹200 crore floor stays the same whatever the amount of currency. This floor is tiny next to today's currency stock. For example, currency in circulation was ₹37.24 lakh crore in 2024-25. So gold does not really limit note issue. Trust in the RBI and monetary policy are the real anchors.
Don't confuse with
- Proportional reserve system (1935-56): the backing grew with the notes issued. 40% of the assets behind notes had to be gold coin, gold bullion or sterling securities. The minimum reserve system uses a fixed amount, not a percentage.
