The Indian rupee appreciated 37 paise to open at 94.30 against the US dollar on June 25, recovering from the previous close of 94.67. The gains came as Brent crude prices declined to around $72 per barrel, their lowest levels since before the Iran conflict, reducing concerns over India's oil import costs and improving overall market sentiment.

A sustained decline in crude oil prices is considered supportive for the rupee as India imports a significant portion of its energy requirements. Lower oil prices help reduce the country's import bill, ease inflationary pressures, and improve the current account balance, thereby strengthening the domestic currency.

Market participants also attributed the rupee's strength to likely intervention by the Reserve Bank of India through state-run banks. The central bank has remained active in the foreign exchange market in recent sessions to curb excessive volatility and support orderly currency movements amid global uncertainty.

The improvement in the rupee coincided with broader optimism across Indian financial markets, as easing geopolitical concerns and softer crude oil prices boosted investor confidence. Analysts believe that continued stability in oil prices and sustained foreign capital inflows could provide further support to the domestic currency in the near term.
