A massive foreign currency inflow of $136.38 billion, driven primarily by the Reserve Bank of India’s special Foreign Currency Non-Resident deposit window, has flooded the domestic banking framework with unprecedented cash, forcing the central bank to launch a historic ₹7 lakh crore liquidity drain that will carry an estimated monthly interest bill of over ₹3,000 crore.
The central bank announced on Friday that it will conduct a 30-day Variable Rate Reverse Repo auction on Monday, September 7, to suck out excess domestic cash after net banking system surplus liquidity soared to an all-time peak of ₹10.32 lakh crore on September 3.
The cash glut stems directly from the RBI’s dollar-mobilisation campaign aimed at bolstering national foreign exchange reserves. Between June and August, the central bank offered zero-cost currency-hedging swap facilities to commercial banks, allowing lenders to offer non-resident Indians interest rates up to 7% on 3-to-5-year deposits. The special window drew $127.23 billion in FCNR(B) deposits before closing a month early on August 31, while overseas borrowings brought total scheme inflows to $136.38 billion.
As the central bank converted those foreign dollars into domestic rupees to credit commercial bank balances, total foreign exchange reserves expanded to a record $729.3 billion. However, this massive dollar purchase simultaneously created a domestic cash surplus, dragging interbank call money rates down into the 4.00–4.95% band—well below the official 5.25% Repo Rate floor.
Daily Interest Bill Crosses ₹100 Crore
To restore control over short-term interest rates, the central bank must now pay commercial lenders to lock away that excess rupee liquidity.
If Monday's 30-day VRRR auction clears around the 5.24% cut-off rate established across 32 separate operations in August, absorbing ₹7 lakh crore for a full month will require the monetary authority to pay out approximately ₹3,015 crore in interest—amounting to roughly ₹100.5 crore per day. Even if the clearing yield settles at a lower rate of 5.00%, the 30-day interest cost to the central bank will reach ₹2,876.71 crore.
Financial analysts point out that while the RBI succeeded in building a formidable foreign exchange cushion, managing the resulting domestic liquidity consequences represents a costly balancing act for central bank balance sheets.
Transition to 30-Day Lock-In
The upcoming operation marks a strategic pivot away from short-term liquidity management. Over the past month, the RBI conducted overnight and short-term VRRR auctions with cumulative notified amounts exceeding ₹41 lakh crore. Just this week, it absorbed ₹6.02 lakh crore in a single day across two 3-day windows.
Because temporary absorptions failed to permanently drain the surplus, short-term money market instruments continued to trade at depressed yields. By shifting to a longer 30-day tenor, the central bank is locking away durable liquidity until October 7.
To prevent structural liquidity stress among commercial lenders, the RBI has introduced a premature exit mechanism via the E-Kuber portal, allowing participating banks to request partial or full early reversals with two working days' advance notice.
The auction window will open between 9.30 AM and 10.00 AM IST on Monday, September 7, with funds scheduled for reversal on October 7.
