Mumbai: The Indian rupee appreciated by 27 paise to 70.87 against the US dollar in early trade on Tuesday as optimism about US-China trade talks and easing crude oil prices enthused investors.

At the interbank foreign exchange, the rupee opened at 70.90, then gained further ground and touched a high of 70.87 against the US dollar, registering a rise of 27 paise over its previous close.
