<h1>Indian rupee gains 21 paise to 85.73 against dollar amid falling crude prices and weaker greenback</h1> The Indian rupee strengthened 21 paise to close at 85.73 against the US dollar, recovering from Monday's 54-paise decline. The currency gained support from falling global crude oil prices, a weaker dollar against major currencies, reduced foreign fund outflows, and firm domestic equity markets. Brent crude dropped 0.55% to $69.20 per barrel while the dollar index fell 0.18% to 97.30. Domestic markets performed well with indices posting gains. Analysts expect the rupee to trade between 85.30-86.00, though trade tariff uncertainties may limit further gains.
