The rupee gained 6 paise to 82.02 against the US dollar in early trade on Thursday supported by steady foreign fund inflows.

However, a surge in crude oil prices capped sharp gains for the local unit, forex traders said.

At the interbank foreign exchange, the domestic unit opened at 82.05, then touched a high of 82.02 against the American currency, registering a rise of 6 paise over its last close.

On Wednesday, the rupee had settled at 82.08 against the dollar.

Softness in the US dollar and sustained FII inflows supported the rupee, forex traders said, adding that the strength in crude oil prices remains a concern for the local unit, as a sharp surge in prices could limit its gains.
