Bank stocks rally as RBI FCNR(B) swap cuts hedging costs

Why bank stocks moved to the front again

Bank stocks returned to the centre of market action after the Reserve Bank of India (RBI) rolled out operational guidelines for a special foreign currency non-resident (bank), or FCNR(B), swap window. Traders also shifted their derivatives positioning, adding bullish bets on banks and reversing part of the earlier bearish stance. The combination helped banks outperform broader indices during the market rebound. Analysts linked the renewed interest to measures designed to mobilise foreign currency borrowings and reduce hedging costs for lenders.

Bank Nifty outperforms Nifty during the rebound

Bank stocks were among the top performers in the latest leg of the rebound. Over the week referenced in the coverage, the Bank Nifty gained 4.25%, beating the Nifty’s 1% rise. In the same period, most constituents of the banking index advanced between 1% and 7%, with Yes Bank and Punjab National Bank (PNB) cited as the exceptions.

A sharper move was seen on Friday, when the Bank Nifty jumped 3% to close at 56,814.8, while the Nifty ended 2% higher at 23,622.9. Derivatives activity also turned supportive, with JM Financial Services’ Akshay Bhagwat pointing to the RBI’s FCNR(B) deposit rate mechanism driving “long delta additions” in banking stocks.

Tuesday’s rally after RBI operational guidelines

The stronger near-term trigger came on Tuesday after the RBI issued operational guidelines for the FCNR(B) swap window. Bank shares surged broadly, with public sector lenders leading.

In the moves highlighted:

• Bank of Baroda rose 5.7%
• Canara Bank gained 4.3%
• Punjab National Bank added 3.7%

BSE’s banking index Bankex climbed 2.2%, while the Sensex rose a more modest 0.5%. The Sensex closed 395 points (0.5%) higher at 73,919.

What the RBI’s FCNR(B) swap window does

The RBI opened a US dollar-rupee forex swap facility for fresh FCNR(B) deposits mobilised by banks. The facility is designed to make foreign currency deposit mobilisation more attractive by reducing the cost of hedging.

Key operational features mentioned in the coverage include:

• The swap facility is for fresh and renewed FCNR(B) deposits with maturities of three to five years.
• The facility covers deposits mobilised between June 8 and September 30, 2026, including eligible renewals.
• It will remain available until October 16, 2026, as per the measures announced earlier.
• The swap is conducted at par, allowing banks to swap foreign currency inflows with the RBI.
• The swap window is available to AD Category I banks.
• While deposits may be in any freely convertible currency, the RBI swap under the scheme is available in US dollars only.
• The RBI guidelines stipulate a one-year lock-in for deposits and prohibit cancellation of swap transactions.

Hedging costs: what changes for banks

Banks and analysts described the framework as a positive development because it addresses a persistent mismatch in which credit growth has outpaced deposit growth. Under the facility, RBI is effectively absorbing the entire hedging cost, which the coverage described as historically in the range of 2.5% to 3.5% annually.

In a comparison to an earlier period, the coverage noted that hedging costs were around 3.5% during a similar programme in 2013. Another part of the reporting described the RBI’s at-par swap as translating into a hedging cost concession of around 280 to 300 basis points versus prevailing market rates.

The framework also exempts FCNR(B) deposits under the scheme from Cash Reserve Ratio (CRR) and Statutory Liquidity Ratio (SLR) requirements, which analysts said can help banks offer competitive rates to non-resident Indian (NRI) depositors without eroding net interest margins.

ECB-related swap support and NOP-INR treatment

Alongside FCNR(B) steps, the RBI also offered a concessional swap facility for eligible External Commercial Borrowings (ECBs), with the hedging cost fixed at 1.5% per annum for eligible overseas borrowings cited in the coverage. The concessions were described as aimed at encouraging overseas fund raising by banks and public sector enterprises.

Separately, the RBI allowed banks to exclude positions arising from its newly announced swap facilities for FCNR(B) deposits, ECBs and overseas foreign-currency borrowings from the calculation of their net overnight open position in rupee (NOP-INR) limits.

Market backdrop: oil down, rupee stronger, global cues steadier

The bank-led move came amid a broader improvement in risk sentiment. The coverage cited a relatively calm West Asia stabilising global markets and oil prices falling about 3%. It also said the rupee strengthened by 35 paise to 95.36-to-the-dollar. These factors coincided with the day’s broader market rebound, though banks remained the clear outperformers.

How the move showed up in index levels

The rally lifted the banking index back above the 55,000 mark after a stretch below it. In one snapshot, Bank Nifty rose 2.1% to 55,194.50, closing above 55,000 after two weeks. Another update noted that at 09:55 am, the Nifty Bank index was up 1.28% at 54,758. A separate market update described NIFTY Bank surging as much as 1.77% or 960 points to an intraday high of 55,024, its biggest single-day gain since April 10.

What banks and analysts said about deposits and funding costs

Analysts said the RBI measures are likely to support deposit mobilisation and reduce funding costs. Dharmesh Kant, head of research at Cholamandalam Securities, said the measures may drive a healthier deposit base for banks and lead to a cheaper cost of funds because the hedging cost on FCNR(B) is borne by the central bank.

Banks and analysts also pointed to the potential scale of the opportunity. If banks succeed in raising the estimated $10 billion through the FCNR(B) route, the coverage said this could translate into nearly Rs 5 lakh crore of additional deposits.

Key figures at a glance

Why this matters for bank investors and traders

The RBI’s approach targets two constraints that the coverage highlighted repeatedly: deposit growth lagging credit growth, and the cost of hedging foreign currency liabilities. By allowing banks to swap fresh three-to-five-year FCNR(B) deposits with the central bank at par, the RBI shifts much of the hedging burden away from banks. Coupled with CRR and SLR exemptions, the measures can change how competitive banks can be when raising NRI deposits, while preserving net interest margins.

On the market side, the response was immediate: bank indices outperformed, PSU banks led gains, and derivatives positioning turned more supportive through “long delta” additions. The next set of signals for investors is likely to come from how much foreign currency deposit mobilisation banks achieve during the eligible window through September 30, 2026, and how the scheme is utilised through October 16, 2026.
