The rupee strengthened by 73 paise and crossed the crucial 73 mark against the US dollar on Tuesday supported by a weak American currency and positive domestic equities.
Forex traders said the domestic unit gathered momentum after the Reserve Bank of India announced various steps to ease pressure on liquidity.
At the interbank forex market, the domestic unit opened at 73.18 against the US dollar, gained further ground during the trading session and finally settled for the day at 72.87 against the greenback, registering a surge of 73 paise over its previous close of 73.60.
