Summary:
India’s 10-year government bond yield rose from 7.18% at September-end to 7.44% on October 28, 2026. Higher crude prices, tighter banking liquidity and monetary policy expectations pressured bond markets, raising concerns about bank treasury valuations and government borrowing costs.
India's government bond market witnessed a sharp rise in borrowing costs during October 2026, with the benchmark 10-year government security (G-Sec) yield climbing around 30 basis points (bps) to nearly 7.49% before easing to 7.44% on October 28. Higher crude oil prices, tightening liquidity, foreign investor outflows and expectations of further interest rate hikes contributed to the increase. The development has raised concerns over government borrowing costs and banks' treasury profitability.
Why Are Government Bond Yields Rising?
India's benchmark 10-year bond yield increased from approximately 7.18% at the end of September to 7.44% on October 28, representing a rise of around 26 bps. During the month, yields briefly approached 7.50%.
Several factors contributed to the movement.
Global crude oil prices remained elevated, increasing inflation concerns for India, which depends heavily on imported petroleum. Higher US Treasury yields and geopolitical uncertainty also reduced demand for emerging-market debt.
Domestic monetary conditions added pressure. On October 7, 2026, the Reserve Bank of India (RBI) increased the repo rate by 25 bps to 5.50% and adopted a calibrated tightening stance.
Expectations of further monetary tightening pushed bond yields higher.

Tight Liquidity Adds Pressure on Bond Markets
Liquidity conditions have tightened considerably since September.
Banking system liquidity declined to approximately ₹30,419 crore on October 27, compared with a peak of nearly ₹11 lakh crore in early September.
Foreign institutional investor outflows and measures aimed at managing currency volatility have contributed to the liquidity squeeze.
The pressure was also visible in short-term government borrowing.
On October 21, the RBI rejected all bids at a ₹23,000 crore Treasury bill auction as investors demanded higher yields.
Tighter liquidity generally reduces demand for bonds, forcing issuers to offer higher returns to attract investors.
How Rising Bond Yields Affect Banks and Government Borrowing
Government bond yields and bond prices move in opposite directions. When yields increase, the market value of existing fixed-rate bonds falls.
This creates mark-to-market losses for banks holding government securities in portfolios valued at prevailing market prices.
Banks with larger long-duration bond holdings may face greater valuation pressure, potentially reducing treasury income.
However, the impact differs according to portfolio classification, hedging arrangements and the proportion of securities held until maturity.
Higher yields also increase the government's cost of issuing fresh debt and refinancing maturing securities.
For example, a 30 bps increase in borrowing costs on ₹1 lakh crore of newly issued debt translates into approximately ₹300 crore of additional annual interest expense.
The increase can eventually influence corporate bond yields and borrowing rates across the financial system.
Bond Market Outlook: Will Yields Remain Elevated?
Bond yields are likely to remain sensitive to inflation, crude oil prices, foreign investment flows and RBI monetary policy.
The benchmark yield has remained close to its highest levels in several years, reflecting uncertainty over future interest rates.
Any improvement in banking liquidity or moderation in crude prices could reduce pressure. Conversely, further policy tightening and sustained foreign outflows may keep yields elevated.
The next RBI Monetary Policy Committee meeting, scheduled for December 2026, will be an important event for bond markets.
Conclusion
The October rise in government bond yields reflects growing pressure from inflation risks, tighter liquidity and monetary policy expectations.
While higher yields increase returns available on newly issued bonds, they also create valuation losses for existing bondholders and raise borrowing costs. Future movements will depend largely on liquidity conditions, inflation and the RBI's policy direction.
