The rupee appreciated 4 paise to 75.69 against the US dollar in the opening trade on Wednesday, following a rally in domestic equities amid hopes of a breakthrough in Russia-Ukraine talks. A weak American currency in the international market also helped the local unit, forex traders said. However, surging global crude prices restricted the gains of the domestic currency, they added. At the interbank foreign exchange, the rupee opened strong at 75.65 against the US dollar but lost some ground to quote at 75.69, a rise of 4 paise over the last close. It was moving in a close range of 75.69 and 75.62 in the morning trade. In the previous session, the rupee had settled at 75.73 against the greenback.
