The Indian banking system is currently swimming in cash. As of August 31, 2026, the total liquidity surplus (excess cash available with banks) reached a massive ₹6.65 lakh crore. This huge pile of money entered the system mainly because of Foreign Currency Non-Resident (Bank) or FCNR (B) deposits. These are fixed deposits kept in foreign currency by NRIs, and they saw a big jump due to a special swap facility (a deal to exchange currencies) offered by the Reserve Bank of India (RBI) between June and August 2026.

To handle this extra cash, the RBI stepped in on Tuesday with two Variable Rate Reverse Repo (VRRR) auctions. A VRRR auction is a tool where the RBI takes money from banks for a short time and pays them interest. This helps the central bank control the total money circulating in the economy. The RBI offered to take back ₹6 lakh crore and ₹4 lakh crore in two separate rounds to keep the market stable.

The results of these auctions showed that banks are feeling cautious. In the first auction, which was for seven days, banks only parked ₹1.14 lakh crore. However, in the second auction for just one night (overnight), banks parked much more, totaling nearly ₹2.60 lakh crore at an interest rate of 5.24 per cent. This shows that bank officers prefer to keep their money available for immediate use rather than locking it up for a full week.

K. Arvind from Tamilnad Mercantile Bank explained that banks want to keep their 'powder dry' (stay ready with cash). They do not want to lock money away for long because they need to be ready if a good loan opportunity comes up suddenly. Because there is still so much extra money left, the RBI has scheduled another one-day auction for September 2, 2026, to take out an additional ₹5 lakh crore from the system.

If these short-term auctions do not work, the RBI has other ways to mop up the cash. They can perform Open Market Operations (OMO) by selling government bonds to banks. The very last option is raising the Cash Reserve Ratio (CRR), which is the fixed percentage of deposits banks must keep with the RBI without earning interest. Raising CRR is usually avoided because it locks away money for a very long time.

RBI Governor Sanjay Malhotra previously mentioned that this surplus was expected. Factors like people putting cash back into banks during the monsoon and high foreign investment have all added to the pile. For regular bankers, this surplus means there is no shortage of funds to lend, but it also means the RBI will be very active in the market to ensure interest rates stay in line with their main policy goals.
