India-US bond yield gap narrows to 22-year low despite rate action

The spread between Indian and American government bond yields has contracted to its tightest level in more than two decades, as rapid US Treasury gains outpace Reserve Bank of India tightening moves. The narrowing gap threatens to deter foreign portfolio investment and sustain depreciation pressure on the rupee.

India-US bond yield gap narrows to 22-year low despite rate action

The yield differential between Indian and US government securities has compressed to near 22-year lows, creating headwinds for India's external account and currency valuation despite the RBI's monetary tightening campaign. The gap—a key metric for foreign investor returns—has shrunk as US Treasury yields have climbed at a faster pace than Indian benchmark rates, reducing the relative attractiveness of domestic fixed-income assets.

Rapid gains in US yields reflect broader global economic shifts and the Federal Reserve's monetary stance, which has outpaced the RBI's incremental rate increases. This dynamic has squeezed the interest rate advantage that typically draws foreign capital into Indian markets, analysts said. The narrower spread is likely to temper inflows of foreign direct and portfolio investment that India's capital account depends upon.

The compression comes as the rupee faces sustained selling pressure from both portfolio outflows and weak domestic demand. Economists cautioned that widening external imbalances could emerge if the yield gap remains compressed for an extended period. The situation underscores the RBI's challenge in calibrating monetary policy amid competing domestic inflation concerns and external sector vulnerabilities.

Market participants are watching for signals on the trajectory of US yields and any adjustments to the RBI's policy pathway. Investors said a reversal in the India-US yield spread would likely restore some appeal to Indian securities and support the currency, though near-term pressures appear entrenched.
