Mumbai, Nov 5: The rupee appreciated 47 paise to 74.29 against the US dollar in opening trade on Thursday, as investor sentiments strengthened amid expectation of Joe Biden's victory in the US Presidential elections.
Traders said positive domestic equities and weak American currency also supported the local unit.
At the interbank forex market, the domestic unit opened at 74.35 against the US dollar, then gained further ground and touched 74.29, registering a rise of 47 paise over its previous close.
On Wednesday, the rupee had plunged by 35 paise to close at its weakest level in over 10 weeks at 74.76 against the US dollar.
"Risk assets have rallied overnight as things have turned around for Biden. He is now seen as winning Michigan and Wisconsin and is just 6 votes short of 270," said Abhishek Goenka, Founder, and CEO, IFA Global.
Goenka further noted that "the deficit between Trump and Biden is widening and it does not seem like a Trump challenge would do much to alter what looks like an almost certain Biden win".
