Inside India’s FCNR(B) Rush: From Early Closure to Record Inflows

If you’ve been following the banking news through August, you will remember the headlines that caught markets off guard- “RBI shuts FCNR (B) swap early”. On 14^th August 2026, RBI through its press release announced that the FCNR (B) swap will be ending on August 31, 2026, instead of September 30, 2026. 

The immediate market response to the announcement came on Monday, when the rupee opened at around ₹95.48/$, before weakening further to ₹95.61/$. The 10-year G-sec yield also rose from 6.76% to 6.81%, as markets factored in the impact of an earlier-than-expected closure on prospective foreign-currency inflows and domestic liquidity conditions. 

When the window closed, the final numbers came in, and they turned out to be far more than what was anticipated. Here's the full picture: what FCNR(B) is, why the RBI pulled the plug early, what happened between the announcement and the close

First, what even is FCNR(B)?

FCNR(B) stands for Foreign Currency Non-Resident (Bank) deposits. It's a scheme that lets Non-Resident Indians (NRIs) park their foreign currency savings in fixed deposits with Indian banks, without converting them into rupees. But there's a catch: banks must hedge the currency risk they take on, and that hedging isn't free.

How it works- 

To make FCNR(B) deposits more attractive to banks, the RBI launched a special zero-cost dollar-rupee swap facility on June 8, 2026. In simple terms: banks could swap the dollars they raised through FCNR(B) deposits for rupees with the RBI itself, instead of hedging in the open market. This made it cheaper for banks to offer NRIs better rates, which in turn encouraged more inflows.

Why the early closure?

At the time of the announcement, the swap facility had already mobilised US$52.3 billion. This was broadly in line with expectations. On July 1, with the outstanding FCNR(B) deposit base at around US$33 billion, expectations were that a response like the 2013 scheme could potentially generate an additional US$40–50 billion of inflows.

The RBI’s own explanation was that the scheme had worked faster than expected. The central bank had already attracted as much foreign currency as it was willing to absorb onto its own balance sheet, leaving limited rationale for continuing to take on additional swap liabilities.

Beyond the stated rationale, there are a few broader macroeconomic considerations that could also help explain the early closure. Continued inflows could have created excess liquidity in the banking system, putting downward pressure on short-term interest rates and, over time, potentially translating into demand-led inflation through the credit channel. This creates a trade-off for the RBI: the same mechanism that strengthens the external balance can, at the margin, loosen domestic financial conditions.

This also brings in the concept of diminishing marginal benefit. The economic value of each additional dollar is now materially lower than it was at the beginning of the programme, as the external liquidity buffer has already strengthened substantially. When the facility was introduced, additional foreign-currency inflows provided a significant buffer against external-sector risks. However, once inflows had reached US$52.3 billion, further accumulation offered progressively less incremental protection, while the liquidity and balance-sheet consequences of absorbing those flows continued to increase.

There are also a cost-of-hedging considerationSBI Research estimates the cost of the swap to the RBI at around US$10 billion. Against the current FCNR(B) mobilisation of US$52.3 billion, this represents a sizeable cost. While this cost should not be viewed in isolation, it becomes increasingly relevant when the marginal benefit of additional inflows has already declined.

Finally, the reserve accumulation needs to be viewed alongside the external liabilities created by the inflows. Every additional inflow strengthens India’s foreign exchange reserves but also adds to the banking system’s external liabilities. A larger FCNR(B) mobilisation would have further boosted the headline reserve position while increasing foreign-currency obligations falling due in 2029–31. The immediate reserve gain therefore comes with a future external liability, making the net benefit of continued accumulation less straightforward.

The scale of the scheme after the closure was visible in the foreign exchange reserves. In the week ended Sept 4, reserves jumped by a record $44.9 billion to $785.7 billion, according to RBI data, the largest weekly increase on record. The surge was large enough to push India past Russia into fourth place globally in foreign exchange reserves, behind China, Japan and Switzerland.

But rupee had a different story.

Despite the stronger reserve position, the rupee remained, around ₹95.5–96 per dollar, in the aftermath, with higher crude prices, a firm USD and global interest rate pressures. The distinction here matters, a higher and stronger reserve position does not automatically translate to a stronger rupee. The FCNR (B) scheme brings dollar into the system and aids the external buffer, but the currency continues to be affected by a much broader set of forces. In other words, the programme has strengthened the country's reserve cushion without eliminating the underlying forces that determine the rupee's day-to-day value.

Taken together, the early closure appears less to be a shift away from attracting foreign capital and more a recalibration of its marginal value. With external buffers strengthened, the focus now shifts to managing its implications for liquidity, bank balance sheets and future external liabilities.
