Context
Surplus liquidity in India’s banking system rose to about ₹5.05 lakh crore as of August 30, 2026, the highest in over four months. The increase was mainly supported by month-end government expenditure and strong foreign-currency deposits.

Explanation
- Banking system liquidity refers to funds readily available with banks to meet their short-term obligations and lending requirements.
- Surplus liquidity occurs when banks collectively hold more funds than their immediate requirements; a deficit implies shortage of funds.
- Government spending injects liquidity when money moves from government balances with the RBI into bank accounts of firms and individuals.
- Foreign-currency inflows can add rupee liquidity when the RBI purchases foreign exchange and releases rupees into the system.
- The RBI manages liquidity through its Liquidity Adjustment Facility (LAF) and other monetary-policy instruments.
- Under the Standing Deposit Facility (SDF), banks can park excess funds with the RBI without providing collateral.
- The RBI can also use Variable Rate Reverse Repo (VRRR) operations to absorb surplus liquidity.
- Persistent excess liquidity can lower short-term interest rates and influence monetary-policy transmission, credit and inflation.
