India’s government bond market is running out of places to hide. Inflation is rising, rate-hike expectations are building, the Reserve Bank of India is preparing to sell bonds and government borrowing remains heavy. Crude oil is elevated and US Treasury yields offer little relief. Each of those forces would normally be enough to unsettle the market. This time, they are arriving together.

The result could be a bear-flattening of the yield curve, with shorter-tenor yields rising faster than longer ones. Traders see the benchmark 10-year gilt yield moving towards 7.15%, while the spread between the 10-year and five-year bonds could narrow to around 20 bps or less. The short end appears particularly vulnerable because monetary policy repricing and the RBI’s open market sales are hitting the same part of the curve.

Inflation & Rate Debate
August inflation has made the RBI’s next move harder to ignore. Consumer inflation accelerated to 4.82% from 4.45% in July, marking a third consecutive month above the central bank’s 4% target. More importantly, the pressure is broadening. Core inflation rose to 4.2% from 3.86%, food inflation accelerated to 5.95% from 5.52%, and several categories including clothing, household goods and education remained close to or above 4%.

The swaps market has noticed. The one-year overnight indexed swap is now pricing as much as 75-80 bps of cumulative tightening, according to traders, as expectations build that the RBI could begin raising rates as early as October. For short-dated bonds, that is already an uncomfortable backdrop. The RBI’s plan to sell ₹1 trillion of government securities through open market operations makes it worse because much of that supply is concentrated in shorter-tenor bonds.

“The short end was anchored by foreign demand in June, and after that surplus liquidity sustained it,” said an assistant general manager of treasury at a state-owned bank. “Looking ahead, neither support is present, so the short end will bear the brunt.” Banks also face the challenge of balancing asset-liability requirements against mark-to-market risk. Securities of up to around seven years are normally useful for ALM, but adding duration becomes harder when the market is pricing higher policy rates.

Supply Glut
Further along the curve, the problem shifts from monetary policy to sheer supply. The central government is scheduled to borrow a gross ₹7.9 trillion in October-March, while state borrowing over the same period is estimated at ₹7.67 trillion-₹8.27 trillion. Combined, Centre and states could bring ₹15.57 trillion-₹16.17 trillion of bonds to market in the second half of 2026-27.

That is a large amount of paper to absorb just as the rate environment is becoming less friendly. The 10-year segment may need to cheapen further to draw demand from banks, mutual funds, insurers and other investors. The long end, however, has one advantage: insurance companies and pension funds need duration. Their structural demand is less sensitive to day-to-day banking system liquidity and could provide some support even as supply builds.

That difference helps explain the flattening view. The short end is being hit by policy repricing and RBI sales. The long end faces heavy issuance too, but it has a more natural buyer base.

Thinning Liquidity, FPI Cushion
Surplus banking system liquidity would ordinarily help absorb some of the borrowing. But the RBI is now actively draining that surplus. OMO sales remove liquidity while simultaneously adding bonds to the market, just as banks are becoming more cautious about adding duration.

The cushion has not disappeared, but it is becoming thinner precisely when the borrowing calendar is getting heavier. That leaves the market more exposed to any further shift in inflation expectations or policy pricing.

There is little comfort overseas either. Elevated crude oil prices are adding to domestic inflation concerns, while high US Treasury yields are weighing on the relative attractiveness of Indian debt. A sustained decline in either could change the mood quickly: cheaper crude would ease fears of inflation pass-through, while lower US yields could reduce external pressure on domestic bonds.

Strong demand at the RBI’s OMO sales could also provide some near-term comfort by showing that the additional supply can be absorbed without disorderly repricing. But traders see that as unlikely to trigger a meaningful rally while the broader rate and supply backdrop remains adverse.

The problem for gilts is therefore not one isolated shock. It is the combination. Rate hikes threaten the short end, RBI sales add supply there, heavy government borrowing weighs further out and crude and US yields keep the global backdrop hostile. For now, the curve may flatten not because the long end is safe, but because the short end has more to lose.
