Banking liquidity surplus shrinks to Rs 541 crore

Why banking liquidity dried up

Banking liquidity in the system has shrunk, with the liquidity surplus down to Rs 541 crore as of October 21, as banks set aside extra funds to meet the daily cash reserve requirement of 99 per cent. The figure, reported by the Economic Times, marks a dramatic tightening from just weeks ago and has pushed short-term borrowing costs higher across the money market.

The immediate trigger is straightforward. When banks park more cash with the Reserve Bank to meet reserve norms, less money sloshes around the interbank market. The weighted average call rate, the rate at which banks lend to each other overnight, rose to 5.65 per cent on Thursday, a full 15 basis points above the repo rate, according to CCIL data. That spread is the market's way of saying cash is scarce.

The Reserve Bank has stepped in with variable rate repo operations to infuse Rs 50,000 crore of liquidity, and the response shows how tight things are. Banks bid Rs 1.62 lakh crore for the funds on offer, more than three times the amount available. The central bank will conduct another three-day VRR auction on Friday. Banking liquidity this thin leaves little buffer for sudden outflows.

Banking liquidity and the call rate

The call rate is where the cash crunch shows up first. In normal times, the overnight rate hovers close to the repo rate, since the repo rate is meant to anchor overnight borrowing costs. A 15-basis-point premium means banks with surplus cash are charging more, and banks short of cash are paying up.

The variable rate repo is the RBI's standard tool for such moments. Unlike the fixed-rate repo window, the variable rate repo lets banks bid for funds at rates they choose, which helps the central bank discover where the market actually needs the money. Heavy bidding at these auctions is a reliable sign that the system wants more liquidity than is currently available.

For borrowers, the direct impact is limited for now. The cash crunch is concentrated in the interbank market rather than in retail lending, and the RBI's operations are designed to keep it there. But if the tightness persists, it can feed through to short-term rates on commercial paper and certificates of deposit, raising funding costs for companies.

What the forex outflow reversal did

The contrast with mid-September could hardly be sharper. Back then, the banking liquidity surplus peaked at Rs 11 lakh crore, an extraordinary figure by any standard. That glut followed the RBI's decision to end an incentives-laden forex-inflow programme, and the unwinding of those forex inflows drained rupees from the system almost as quickly as they had arrived.

The mechanics behind the banking liquidity swing are worth spelling out. When forex inflows surge, the RBI buys dollars and releases rupees, swelling banking liquidity. When the programme ended and the flows reversed, the central bank sold dollars and absorbed rupees, shrinking the surplus. The swing from Rs 11 lakh crore to Rs 541 crore in about five weeks shows how sensitive the system has become to these flows.

Festival-season currency demand has added to the pressure. Households withdraw more cash around Diwali, which pulls money out of the banking system and into circulation. Combined with tax outflows and the forex reversal, the seasonal demand has left the system running on empty.

What banking liquidity looks like next

The RBI's Friday auction will offer some relief, but the underlying drivers will take longer to fade. Currency in circulation typically stays elevated through the festival season, which keeps banking liquidity under pressure, and the forex-inflow reversal has structurally reduced the surplus. Another such operation, or a longer-tenor infusion, remains on the table if bidding stays heavy.

For now, the cash crunch is a money-market story rather than a credit story. Lending rates for households and businesses have not moved, and the central bank has ample tools to add liquidity if needed. But the speed of the swing, from an Rs 11 lakh crore liquidity surplus to Rs 541 crore, is a reminder of how quickly comfort can turn into constraint.
