Benchmark 10-Year Bond Yield Climbs to 7.07% as Indian Sovereign Debt Marks Fifth Weekly Fall on Fed Rate Hike and RBI Tightening

Indian sovereign debt markets logged their fifth straight week of losses on Friday, hit by a compounding series of domestic liquidity curbs and tightening global monetary conditions. The benchmark 6.94% 2036 bond yield closed at 7.0686%, up from 7.0463% on Thursday, registering a weekly increase of 4.5 basis points and extending a prolonged selloff that has kept domestic debt bears firmly in control.

Market participants faced a triple blow over the trading week: surging global debt yields, a hawkish US central bank rate increase, and direct supply absorption pressure stemming from the Reserve Bank of India's (RBI) open market operations.

Fed Moves and Global Spillovers

The US Federal Reserve lifted the target federal funds rate by 25 basis points on Wednesday—its first rate hike since July 2023—and signaled the potential for another rate increase before the end of the year as it combats persistent inflation. The move pushed the US 10-year Treasury yield firmly past 5%, while the 2-year yield hovered near 4.75%.

The hardening of US yields has narrowed the interest rate differential between India and the United States, raising concerns over foreign capital outflows from emerging debt markets. In response, Overnight Indexed Swap (OIS) rates in India advanced by roughly 5 basis points across major tenors, with the one-year swap rate standing at 6.14% and the five-year rate rising to 6.67%.

RBI Liquidity Squeeze Weighs on Sentiment

Adding to the selling pressure, domestic bond supplies expanded after the RBI initiated open market sales of government securities to actively absorb excess banking system liquidity. The central bank outlined plans to sell bonds worth an aggregate of ₹1 trillion ($10.42 billion) over a two-week period, executing the first tranche of ₹500 billion on Thursday.

The introduction of sovereign debt supply directly into a demand-light secondary market exacerbated the downward pressure on bond prices, forcing primary dealers and state-run banks to mark down portfolios.

Heightened Odds of an October Policy Hike

The combination of overseas monetary tightening and domestic inflation trends has prompted multiple brokerage firms and institutional lenders—including Citi and Deutsche Bank—to bring forward their projections for an RBI rate hike to the upcoming October Monetary Policy Committee (MPC) meeting.

Domestic macro indicators and upcoming policy triggers influencing bond yields include:

• Consumer Price Index Inflation: India's retail inflation accelerated to 4.82% in August from 4.45% in July, reducing the central bank's policy leeway to keep interest rates steady.
• Currency and Outflow Protection: An October rate increase is seen by market participants as an essential tool to defend the rupee and protect yield spreads against higher US Treasury returns.
• Credit Market Ripple Effects: As sovereign yields climb past the 7.05% threshold, corporate bond issuance costs and bank lending benchmarks are expected to adjust upwards, increasing financial costs for corporate borrowers across infrastructure and manufacturing sectors.

With the central bank's liquidity tightening underway and external rate dynamics remaining restrictive, traders anticipate benchmark yields to trade with an upward bias heading into the MPC's early October decision.
