Indian rupee hits one-month low as oil lifts bond yields

Indian rupee fell 0.4% to 95.92 per dollar on Tuesday, a more than one-month low, after Brent crude neared $108 and US rate bets firmed.

At 12:30 p.m. IST, the rupee was quoted at 95.92 to the dollar, weaker on the day and in line with losses across most regional currencies. Likely dollar sales by the Reserve Bank of India through government-owned banks limited the decline, according to the market account.

Brent nears $108

Brent crude rose nearly 2% to $107.7 a barrel after attacks on Saudi Arabian energy infrastructure left the East-West Pipeline offline. The disruption added pressure to shipping risk in the Gulf, a route central to energy flows into Asia.

Oil has climbed nearly 20% so far this month, an increase that matters more for economies that buy much of their energy abroad. For India, higher crude prices can feed into the import bill, transport costs and inflation expectations.

The bond market moved in the same direction as the currency pressure. The yield on India's 10-year benchmark government note rose 7 basis points to 7.09% on Tuesday, from about 7.02%, meaning bond prices fell as yields climbed.

RBI bond sales loom

The currency move came as the RBI appeared to remain active in both the foreign-exchange and liquidity markets. The central bank likely conducted dollar-rupee sell-buy swaps for a fourth straight trading session, a tool used to absorb excess rupee liquidity from the banking system.

RBI Governor Sanjay Malhotra said Friday that open-market bond sales and foreign-exchange swaps were among the tools available to drain liquidity. Later that day, the RBI announced bond sales worth 1 trillion rupees, or $10.43 billion at the stated exchange rate, for September.

MUFG said in a note that it forecasts USD/INR at 95.50 by December 2026 and 96.50 by June 2027, compared with Tuesday's 95.92 quote. The bank described that path as gradual rupee depreciation against the dollar and modest underperformance versus other Asian currencies.

Scenarios turn on oil and swaps

If oil holds near current levels, the mechanism is straightforward: India's import costs rise, inflation expectations become harder to contain and the RBI has less room to tolerate loose rupee liquidity. Globally, that would keep energy-importing Asian economies more exposed to US rate pricing; domestically, refiners, airlines and bond investors would face higher input or funding costs.

If crude prices ease and Federal Reserve rate expectations soften, pressure on the rupee would be more likely to pass through the RBI's liquidity operations than through the trade bill. In that path, global macro stress would be lower, the RBI could rely more on measured swaps and bond sales, and Indian rate-sensitive sectors would get some relief from yield pressure.

The main uncertainty is whether the oil shock persists long enough to alter inflation expectations before the RBI's September bond sales take effect. A second uncertainty is whether dollar demand across Asia continues to weigh on regional currencies, limiting the impact of any India-specific intervention.
