A higher opening of domestic equity market, however, capped the loss, brokers said.
At the Interbank Foreign Exchange, the rupee opened sharp lower at 70.27 a dollar against the previous close of 70.06. The domestic unit moved in a tight range of 70.31 to 70.22 in the morning trade.
Wednesday, the rupee trimmed its early gains to settle 8 paise higher at 70.06 against the US currency.
Brent crude, the international benchmark, was down 1.18 per cent at USD 54.64 per barrel.
On a net basis, foreign portfolio investors (FPIs) bought shares worth Rs 80.28 crore Wednesday, while domestic institutional investors (DIIs) were net sellers to the tune of Rs 137.63 crore.
