Record Inflows Stabilize Rupee
India’s recent dollar-mobilization drive has yielded results far exceeding initial projections. The special Foreign Currency Non-Resident (B) (FCNR(B)) window, launched in June 2026 to alleviate pressure on the rupee, attracted $127 billion by the end of August 2026. When combined with $9 billion from external commercial borrowings and offshore financial centers, total mobilization reached approximately $136 billion.
The response was so robust that the RBI closed the FCNR(B) scheme a month ahead of its original September 30, 2026, deadline. Consequently, foreign exchange reserves have climbed by $103 billion since May 2026, reaching a record high of $786 billion. The rupee has stabilized within the ₹94-96 per dollar range, reversing the sharp depreciation seen between May 2024 and May 2026.
The Liquidity Dilemma
While the currency stabilization is a clear success, it has triggered a significant second-order effect: a massive surplus of rupee liquidity in the banking system. As overseas investors converted dollars to rupees, the banking system’s liquidity moved from near-neutral levels to approximately ₹11 trillion. After adjusting for government cash balances, durable liquidity estimates have risen from about ₹5 trillion to at least ₹14 trillion, representing nearly 5% of bank net demand and time liabilities.
This surge has led to a "pseudo rate cut" in the domestic market. Weighted average overnight rates have fallen below 5%, and collateralized market repo rates have traded around 4.5-4.65%. This occurs despite the Monetary Policy Committee not cutting the policy rate, creating an unintended easing of financial conditions at a time when inflation risks are rising.
RBI’s Sterilization Strategy
The RBI faces a complex balancing act to absorb this excess liquidity without undermining the attractiveness of the deposit scheme or pushing government bond yields too high. The central bank has announced Open Market Operation (OMO) sales of ₹1 trillion in three tranches during September. This is a critical step to sterilize the surplus, though other tools like Cash Reserve Ratio (CRR) adjustments or forex swaps carry their own costs and risks.
Analysts note that the scale of this operation is unprecedented compared to the 2013 FCNR(B) exercise, which attracted only $34 billion. The current liquidity impact is roughly 6.5 times larger, making natural absorption impossible and requiring active central bank intervention.
Impact on Banks and Bond Markets
For the banking sector, the inflows are a significant positive. Deposit growth has surged to 17.8% year-on-year, well above the previous 11-12% trend. Between June and August, banks mobilized ₹18.7 trillion in deposits, compared to a historical average of ₹4 trillion for the same period. This reduces dependence on expensive wholesale funding, with NRI deposits potentially meeting nearly one-third of the estimated ₹34 trillion lending requirement if credit growth reaches 16% by year-end.
However, the bond market faces mixed signals. While strong liquidity typically supports lower yields, heavy government borrowing in the second half of FY27 and elevated global rates are exerting upward pressure. The 10-year government bond yield is hovering around 7%, with short-end curves steepening. Investors are advised to monitor how aggressively the RBI manages the rupee liquidity, as this will be a key determinant for future yield trajectories and monetary conditions.
