Record foreign-currency deposits could ease pressure from elevated credit-deposit ratios, strengthen medium-term liquidity and help banks manage asset-liability mismatches

Indian banks have received a significant funding boost after mobilising a record $127 billion through Foreign Currency Non-Resident Bank (FCNR(B)) deposits between June 8 and August 31, 2026, according to S&P Global Ratings.

The rating agency described the mobilisation as a “shot in the arm” for Indian banks, saying the inflow has eased funding pressures at a time when credit growth has been running ahead of deposit growth for several years.

The amount mobilised is equivalent to around 4.5 per cent of the Indian banking system’s deposit base as of March 31, 2026, highlighting the scale of the exercise.

RBI Incentive Helped Attract Overseas Deposits

The sharp increase in FCNR(B) deposits followed measures by the Reserve Bank of India (RBI) designed to encourage foreign-currency inflows.

Between early June and August, the RBI absorbed the full hedging cost for the principal amount of eligible three-to-five-year FCNR(B) deposits. This allowed Indian banks to offer more attractive interest rates to non-resident depositors while reducing the cost associated with managing the currency exposure.

The higher rates encouraged the Indian diaspora and other eligible depositors to channel a substantial amount of foreign-currency savings into Indian banks.

For banks, the result was a sizeable pool of relatively stable foreign-currency funding.

Deposit Growth Has Been a Key Challenge

The importance of the FCNR(B) mobilisation becomes clearer against the backdrop of India's banking-sector funding environment.

Credit growth has exceeded deposit growth for much of the past four years, putting pressure on banks to compete aggressively for deposits.

Banks have increasingly had to offer competitive deposit rates to attract and retain customers, while strong loan demand has continued to consume balance-sheet liquidity.

The inflow of FCNR(B) deposits provides banks with an additional funding source without relying exclusively on domestic retail deposits.

Three-to-Five-Year Tenor Improves Funding Stability

According to S&P, the three-to-five-year tenor of the FCNR(B) deposits is particularly beneficial because it provides banks with medium-term funding.

Longer-duration liabilities can help banks better match the maturity profile of their assets and reduce asset-liability duration mismatches.

S&P credit analyst Geeta Chugh said the deposits should improve funding stability and help banks bridge asset-liability duration gaps.

This can be particularly relevant for banks that have expanded their loan books faster than their deposit franchises.

Liquidity Emerges as the Biggest Beneficiary

S&P identified liquidity as the clearest beneficiary of the record FCNR(B) mobilisation.

Indian banks have been operating with elevated credit-deposit ratios, meaning a relatively large proportion of deposits is being deployed into loans.

The additional foreign-currency funding gives banks greater flexibility in managing liquidity and funding requirements.

It can also reduce some of the immediate pressure to compete for domestic deposits, although the impact will vary from bank to bank depending on the size and composition of their FCNR(B) mobilisation.

Potential Balance-Sheet Impact Could Be Larger Than $127 Billion

The impact of the programme could extend beyond the headline $127 billion deposit figure.

S&P said bank balance sheets could expand by considerably more if customers borrow against their FCNR(B) deposits.

The rating agency estimated that the overall balance-sheet increase could potentially reach $190 billion-$220 billion, assuming around 50-75 per cent of the deposits are leveraged through loans against pledged FCNR(B) deposits.

This means the deposit mobilisation could create additional lending activity within the banking system.

Loans Against Deposits Could Amplify the Impact

FCNR(B) deposits can also serve as collateral for loans.

When depositors borrow against their foreign-currency deposits, banks can generate additional assets while retaining the underlying deposit liability.

S&P noted that low-spread loans and offshore borrowings used to fund them would appear on bank balance sheets.

Consequently, the overall balance-sheet effect could be larger than the initial amount of foreign-currency deposits mobilised.

Funding Cost Remains an Important Consideration

While the FCNR(B) inflow is positive from a liquidity perspective, banks will still need to manage the cost of these deposits carefully.

The special RBI measures enabled banks to offer more attractive rates, but the deposits are not cost-free funding.

Banks will need to deploy the funds efficiently enough to generate adequate spreads while maintaining appropriate liquidity and risk controls.

A rise in FCNR(B) deposit costs could therefore partly offset the benefits of improved funding availability.

Implications for Net Interest Margins

The impact on net interest margins (NIMs) could differ across banks.

If banks deploy the additional funding into higher-yielding assets, the incremental liquidity could support interest income. However, if funds are deployed into lower-yielding assets or if competition pushes up deposit costs elsewhere, the benefit to margins could be more limited.

Banks with stronger loan demand and better asset-liability management may therefore be better positioned to convert the additional liquidity into profitable balance-sheet growth.

Could Reduce Pressure on Domestic Deposits

One of the indirect benefits of the FCNR(B) inflow is that it could moderate competition for domestic deposits.

Indian banks have been competing aggressively for deposits as loan growth has outpaced deposit mobilisation. Higher deposit rates can raise the overall cost of funds and place pressure on margins.

Foreign-currency deposits provide an additional source of funding and could give banks more flexibility in managing their domestic deposit pricing.

However, the extent of this benefit will depend on how long FCNR(B) inflows remain elevated and whether the special incentives continue.

Currency and Asset-Liability Management Remain Important

Foreign-currency funding also requires careful risk management.

Banks must manage currency exposures, interest-rate risks and maturity mismatches associated with foreign-currency deposits and related lending.

The RBI's hedging support played an important role in making the mobilisation more attractive, but banks will still need to ensure that their balance sheets remain appropriately hedged and that foreign-currency liabilities are matched with suitable assets or hedging arrangements.

What It Means for Indian Banks

The FCNR(B) mobilisation can potentially benefit banks through several channels:

• Improved medium-term liquidity

• Greater funding diversification

• Lower pressure on domestic deposit mobilisation

• Better asset-liability duration matching

• Potential balance-sheet expansion

• Greater flexibility in supporting credit growth

• Additional lending opportunities against pledged deposits

However, the ultimate financial benefit will depend on deposit costs, loan pricing, credit quality, currency management and the ability of banks to deploy the funds productively.

Credit Growth Could Get Additional Support

The additional funding comes at a time when India's banking system continues to support credit expansion.

If banks use part of the additional liquidity to support incremental lending, sectors such as retail, infrastructure, manufacturing and businesses could potentially gain from improved availability of funds.

At the same time, banks will need to maintain underwriting standards. Faster balance-sheet growth without adequate credit discipline could create asset-quality risks over the longer term.

Market Outlook

The mobilisation of $127 billion in FCNR(B) deposits marks a significant development for India's banking sector. S&P's assessment suggests that the immediate benefit is likely to be through improved liquidity and more stable medium-term funding rather than simply an increase in deposits.

The potential for the overall banking-system balance sheet to expand to $190 billion-$220 billion under S&P's assumptions makes the programme even more significant for credit and liquidity conditions.

For investors, the key factors to monitor will be FCNR(B) funding costs, loan deployment, credit-deposit ratios, net interest margins, foreign-currency risk management and the sustainability of deposit inflows after the special RBI measures expire.

The programme has provided Indian banks with an important additional funding channel, but the longer-term benefit will ultimately depend on how efficiently banks convert that liquidity into sustainable, well-priced and high-quality assets.
