Rupee vs Dollar Today 18 August 2026: Rupee Opens at Rs 95.66 Down 6 Paise on Crude Surge and RBI Swap Action

The rupee vs dollar today opened 6 paise lower at Rs 95.66 on 18 August 2026, under pressure from three simultaneous headwinds: rising crude oil prices as the US-Iran ceasefire collapsed, higher US Treasury bond yields making dollar assets more attractive, and the Reserve Bank of India's decision to shorten its foreign-currency deposit swap facility. The the exchange rate weakness is mechanically linked to the same geopolitical risk premium driving Brent crude to $91.14 per barrel, as a weaker rupee is partly a consequence of higher dollar demand for oil imports.

The RBI decision to shorten the foreign-currency deposit swap facility reduces dollar liquidity support in the system, allowing the the exchange rate to move more freely in response to external factors. The Sensex was also negative on 18 August at 77,385.57 (-0.44%), reflecting the same macro headwinds that are weighing on the rupee vs dollar today. Currency and equity markets are responding in tandem to the elevated geopolitical risk environment.

Drivers of this reading Weakness

Crude Oil Prices Mechanically Weaken the Rupee vs Dollar Today

India imports approximately 85% of its crude oil requirement and pays in US dollars. When Brent crude rises to $91.14 per barrel on US-Iran geopolitical tensions, Indian oil importers need more dollars to pay for the same volume of crude, increasing dollar demand and weakening the rupee vs dollar today. This is the most direct driver: the the exchange rate level is partly determined by the size of India's oil import bill in dollar terms, which rises when crude prices rise.

US Bond Yields Pull Capital Toward Dollars

Higher US Treasury yields make dollar-denominated bonds more attractive relative to emerging market assets. When yields rise, global capital gravitates toward dollar assets and away from currencies like the rupee. The rupee vs dollar today weakness on this account is a global emerging market phenomenon rather than India-specific: most Asian and EM currencies weakened alongside the Indian rupee when US yields moved higher in the current session.
