Indian Rupee and Bonds Fall as Oil Prices Surge

The Reserve Bank of India triggered market volatility on August 18, 2026, by closing its concessional FCN (B) zero-cost forex-swap facility a month earlier than expected. This facility had provided a critical hedge for banks managing foreign-currency deposits from non-resident Indians, which had previously injected over $50 billion into the system and supported bond demand.

Simultaneously, the Indian rupee depreciated 7 paise to close at 95.68 against the U.S. dollar. This decline coincided with a drop in government bond values and a rise in benchmark yields. Both trends were driven by Brent crude oil prices surging above $90 per barrel following the expiration of a 60-day ceasefire between the United States and Iran on Monday. The lack of progress on a peace deal to reopen the Strait of Hormuz further pressured market sentiment.

Domestic equity markets also fell, with the Sensex settling at 77,235.46 and the Nifty at 24,154.90. Additional pressure came from elevated U.S. 10-year Treasury yields and foreign institutional investors selling ₹2,535.10 crore in equities, the highest volume in three weeks. Traders are now monitoring an upcoming 202-billion-rupee state debt sale to assess investor appetite.
