The rupee depreciated by 18 paise to close at 82.12 (provisional) against the US dollar on Tuesday amid fresh foreign capital outflows and rising crude prices in the international market.

At the interbank foreign exchange, the domestic unit opened weak at 82.03 and touched the intra-day low of 82.17.

The domestic unit settled at 82.12 (provisional) against the US dollar, registering a loss of 18 paise over the previous close.

On Monday, the rupee settled at 81.94 against the dollar.

The decline in the rupee can be attributed to the recovery in the dollar index and an increase in crude oil prices, which put pressure on the rupee, said Jateen Trivedi, VP Research Analyst at LKP Securities.

He said market participants were eagerly awaiting US Federal Reserve Chair Jerome Powell's upcoming speech, "as it is expected to provide important insights".

"In the short term, the rupee is expected to trade within the range of 81.70 to 82.25. After experiencing a strong rally over the past couple of weeks, the rupee witnessed profit booking ahead of the significant speech. However, the overall trend for the rupee remains positive as long as it holds above 82.40," Trivedi added.

Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, was down 0.07 per cent at 102.45.

Crude oil price benchmark Brent crude was up 0.92 per cent to USD 76.79 per barrel.

In the domestic equity market, the 30-share BSE Sensex climbed 159.40 points or 0.25 per cent to settle at 63,327.70, while broader NSE Nifty went up 61.25 points or 0.33 per cent to close at 18,816.70.
