The Reserve Bank of India (RBI) recently held two Variable Rate Reverse Repo (VRRR) auctions to soak up extra cash from the banking system. In these auctions, banks lend their surplus money to the RBI to earn interest. However, a clear trend emerged: banks prefer the one-day option over the 30-day option. Even though the RBI wanted to take in more money for the longer period, bankers chose to keep their funds flexible.

At the 30-day auction, the RBI aimed to absorb 7 lakh crore rupees, but banks only offered 2,59,276 crore rupees. In contrast, during the one-day auction, banks were much more active, offering 3,53,390 crore rupees against a target of 5 lakh crore rupees. Both auctions resulted in a Weighted Average Rate (WAR) of 5.24 percent. This shows that banks are not looking for higher rates, but rather for liquidity (the ability to get cash quickly).

The main reason for this behavior is the upcoming quarter-end. Bankers want to 'keep their powder dry,' which means they want to have cash ready to give out as loans. If a bank locks its money away for 30 days, it might miss out on a big corporate loan opportunity that pays a much higher interest rate than the RBI's 5.24 percent. By using the overnight window, they can get their money back the very next day if a borrower walks in.

There is a massive amount of extra cash in the system right now. Between late August and September 6, excess liquidity (surplus cash) jumped by over 4.5 lakh crore rupees to reach a total of 11,16,006.50 crore rupees. Experts believe this surplus could swell even further to 12 lakh crore rupees very soon. This is a huge amount of idle money sitting in the banking corridors.

Where did all this money come from? It mostly came from FCNR(B) deposits (Foreign Currency Non-Resident deposits). These are deposits made by NRIs in foreign currency. The RBI had offered a special 'concessional swap facility' from June to August. This scheme allowed banks to swap foreign currency for Indian rupees at a good rate. Because of this, banks collected a staggering $127.23 billion in these deposits alone.

For bank officers on the ground, this situation means there is no shortage of funds to meet lending targets. However, the challenge is managing the 'cost of carry' (the cost of holding onto money that isn't yet earning a high return). Treasury heads, like K Arvind from Tamilnad Mercantile Bank, noted that banks are being cautious. They would rather earn a small amount overnight than be stuck in a long-term commitment while loan demand is picking up.

Looking ahead, the market is watching September 11 closely. This is the final day for banks to complete their currency swaps with the RBI. After this date, we will see if the liquidity surplus stabilizes. Customers might find it easier to get loans approved quickly since banks are sitting on record levels of cash and are eager to deploy it into productive assets rather than leaving it with the RBI.
