In 2026, the Reserve Bank of India's (RBI) special foreign-exchange swap facility for FCNR(B) deposits emerged as a big source for mobilisation of foreign-currency. As at August 31, 2026, the banks had been mobilised $127.226 billion through FCNR(B) deposits and $136.4 billion through the overall facility. The mobilisation strengthened India’s foreign-exchange resources and external liquidity position, while the associated RBI swaps also created substantial rupee liquidity in the domestic banking system. It has ramifications for government securities, money-market rates and bond yields in India. The effect is different, however, for short- and long-term bonds.
What are FCNR(B) deposits and Why Do They Matter?
Foreign Currency Non-Resident (Bank) (FCNR(B)) deposits are term deposits accepted by authorised Indian banks from eligible non-residents in permitted foreign currencies. These accounts are in foreign currency, and the principal and interest will be paid accordingly, subject to the applicable regulations, compared with NRE deposits which are maintained in rupees.
These deposits provide Indian banks with access to foreign-currency funding. Under the special 2026 arrangement, the RBI provided rupee liquidity to eligible banks against eligible foreign currency resources through USD-INR forex swaps.
The importance of FCNR deposits increased considerably in 2026 because the scale of mobilisation was much larger than initially anticipated.
Why the RBI Reopened the FCNR(B) Window in 2026
The RBI introduced the special facility on June 8, 2026, against the backdrop of the need to strengthen foreign-exchange inflows and external sector resilience.
Under the arrangement, the RBI policy offered a USD/INR forex swap facility linked to FCNR(B) deposits. It also introduced concessional arrangements for eligible external commercial borrowings and overseas foreign-currency borrowings.
The facility included temporary changes to interest-rate restrictions for fresh three-to-five-year FCNR(B) deposits, making it easier for banks to attract longer-term foreign-currency resources.
The response was considerably larger than expected. Provisional data showed $127.226 billion had been mobilised through FCNR(B) deposits by August 31, 2026. The FCNR(B) window was closed early on August 31, 2026 after the RBI said its objective had been achieved.
How the $127 Billion FCNR(B) Inflows Triggered a Surge in India's Liquidity Conditions
The effect on domestic liquidity can be understood in a few stages:
Step 1: Foreign currency enters Indian banks
Eligible non-residents place foreign currency with Indian banks through FCNR(B) deposits.
Step 2: The RBI swap provides rupee liquidity
Under the special arrangement, banks receive rupees against their foreign-currency resources. This increases rupee liquidity in the banking system.
Step 3: Banks receive additional funds
Banks can use the additional rupee funds for lending, investments or other eligible purposes.
Step 4: Surplus funds enter financial markets
When immediate credit demand does not absorb the additional liquidity, banks may keep funds with the RBI or invest in short-duration securities.
The result was a sharp increase in banking-system liquidity. Reports indicated that surplus liquidity reached around ₹9.70 lakh crore after the initial $127.23 billion mobilisation and subsequently rose further.
The Link Between FCNR(B) Inflows, Government Bonds and Bond Yields
Large changes in banking liquidity can influence demand for government securities. When banks have surplus funds, they may increase their holdings of Treasury bills, short-term government securities, and other high-quality debt instruments.
Higher demand for bonds generally supports their prices. Since bond prices and yields move in opposite directions, increased demand can put downward pressure on yields.
The impact was particularly visible in short-term money-market rates. Reports showed a decline in certificate-of-deposit rates during the period of abundant liquidity.
However, the effect on government bonds is not one-directional. The RBI also uses government bond sales to absorb excess liquidity. Higher bond supply can place upward pressure on yields.
This means FCNR(B) inflows can create two opposing forces: additional banking liquidity may increase bond demand, while RBI operations can increase the supply of securities available to investors.
Short Term and Long Term bonds are Reacting Differently
Short-term government bond yeilds are generally more sensitive to near-term money-market and liquidity conditions. When banks have excess funds, demand for Treasury bills and other short-maturity government securities can increase, potentially reducing short-term yields.
Long-term bonds respond to a broader set of factors. These include inflation expectations, government borrowing, fiscal conditions, global interest rates and expectations about future monetary policy.
This difference is important because excess liquidity does not automatically result in lower yields across the entire yield curve. Short-term yields can respond quickly to changes in rupee liquidity, while longer-term yields may remain influenced by government borrowing and global market conditions.
Consequently, investors should examine the maturity segment separately when assessing changes in bond yields India.
The Investment Implications of the FCNR(B) Window for Bond Investors
For bond investors, the introduction of the FCNR(B) window highlights the importance of tracking liquidity alongside the RBI’s interest-rate stance. Surplus rupee liquidity can support demand for short-duration debt, while subsequent liquidity absorption can alter market conditions.
Investors also need to distinguish between temporary liquidity changes and longer-term changes in interest rates. A temporary surplus may influence short-term yields without changing the underlying factors affecting long-term borrowing costs.
Long-duration investors remain exposed to inflation expectations, government borrowing requirements and global bond yields. Therefore, FCNR(B) flows should be considered alongside these factors rather than treated as a standalone indicator for future bond-market movements.
The Repayment Cycle, Liquidity Risks and Market Opportunities
The liquidity created by the FCNR(B) facility is not permanent. FCNR(B) deposits have defined maturities, creating future foreign-currency repayment obligations for banks.
The cycle can be understood as follows:
1. Mobilisation: Banks attract foreign-currency deposits from eligible non-residents.
2. Swap: The RBI policy provides rupee liquidity against the foreign-currency resources.
3. Deployment: Banks use or invest the rupee funds.
4. Liquidity management: The RBI absorbs excess rupee liquidity through instruments such as reverse repos, foreign-exchange operations and bond sales.
5. Maturity and repayment: At maturity, banks must meet their foreign currency repayment obligations to depositors. Under the swap structure, the corresponding unwinding of the transaction also involves the return of rupee funds to the RBI, thereby potentially reducing rupee liquidity.
This makes both rupee and dollar liquidity important considerations. Large initial inflows can ease domestic funding conditions, while repayments can create fresh foreign-currency requirements for banks.
Conclusion
The 2026 FCNR(B) exercise has strengthened the connection between foreign-currency mobilisation, domestic liquidity and India’s debt markets. The first tranche of $127.2 billion mobilisation saw creation of a significant rupee liquidity surplus, and subsequent RBI operations illustrated the ability to manage the liquidity through various instruments. Whether it has a long-term impact on bond yields will be determined by the repayment cycle, borrowing by the government, inflation, RBI operations and global interest rates. When considering yield changes, liquidity and the overall government securities market, bond investors should look at these factors in combination.
Frequently Asked Questions About the RBI's FCNR(B) Window
How does the FCNR(B) window differ from other forms of foreign capital inflows?
FCNR(B) Deposit means foreign currency deposits raised by Indian banks from eligible non-residents of India which constitute a liability of the bank, with repayment due according to the deposit terms and there is a commitment to repayment on maturity.
Could FCNR(B) inflows affect India's foreign exchange reserves?
Yes. This type of inflow can help increase external liquidity and can affect the country's external liquidity and foreign-exchange position despite the fact that there are a number of other factors that impact the foreign exchange reserves.
What impact could the FCNR(B) window have on India's bond market?
Some of this effect can be offset by RBI's liquidity absorption operations and additional rupee liquidity can raise demand for short-term government securities to impact the money-market rates.
Can higher FCNR(B) inflows reduce pressure on India's government bond yields?
They can contribute to the demand for bonds by increasing the liquidity of the banking system, particularly at the short end. Borrowings, inflation, RBI actions and global yields also play a part in the overall effect.
