MUMBAI: The rupee appreciated 34 paise to close at 81.38 (provisional) against the US dollar on Wednesday as a weak greenback in the overseas market and a rally in domestic equities boosted investor sentiment.
At the interbank foreign exchange market, the local unit opened at 81.63 and touched an intra-day high of 81.38 and a low of 81.64 against the greenback.
The local unit finally settled at 81.38, registering a rise of 34 paise over its previous close.
On Tuesday, the rupee declined 4 paise to close at 81.72 against the US dollar.
The Indian rupee registered the first monthly gains in the past eleven-months following a rebound in the risk assets, lower crude oil prices and foreign fund inflows, said Dilip Parmar, Research Analyst, HDFC Securities.
"It is poised to end the month 1.6 per cent higher, its biggest gain since August 2021," Parmar said.
Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, slipped 0.29 per cent to 106.51.
According to Parmar, the dollar index slipped, weighed by ongoing demand for riskier assets as investors speculated that China may gradually unwind its COVID curbs.
