Mumbai, Jun 29 (PTI) The rupee pared initial gains and settled lower by 6 paise at 94.51 against the US dollar on Monday, as renewed geopolitical tensions hit investors' risk appetite.

Forex traders said the rupee opened on a positive note with crude oil prices remaining supportive and foreign inflows improving, but a renewed flare-up in geopolitical tensions after fresh military exchanges between the US and Iran dented investor sentiment.

At the interbank foreign exchange market, the rupee opened at 94.36, then gained momentum and touched an intraday high of 94.25 and a low of 94.56 against the American currency.

At the end of Monday's trade, the rupee was quoted at 94.51, down by 6 paise over its previous close.

On Thursday, the rupee settled at 94.45 against the US dollar.

Indian stock, currency and commodities markets were shut on Friday on account of Muharram.

"We expect the rupee to trade with a negative bias on renewed geopolitical tensions between the US and Iran. Overall strength in the US dollar on a hawkish Fed may also pressurise the rupee.

"However, a decline in crude oil prices and easing concerns over inflation may support the rupee at lower levels. USDINR spot price is expected to trade in a range of 94.20 to 94.80," said Anuj Choudhary, Research Analyst, Mirae Asset ShareKhan.

Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, was trading at 101.14, down 0.21 per cent.

Brent crude, the global oil benchmark, was trading higher by 1.4 per cent at USD 73.62 per barrel in futures trade. ​ Iran again launched drone and missile attacks targeting Bahrain and Kuwait on Sunday following new US airstrikes against the Islamic Republic.

Rupee weakness reflects geopolitical tensions, dollar strength, and shifting crude oil trends in the foreign exchange market. The rupee weakened against the US dollar after giving up early gains, with renewed geopolitical tensions reducing investor risk appetite and weighing on sentiment in the foreign exchange market. Traders said supportive crude oil prices and improved foreign inflows initially helped the currency, but broader dollar strength kept pressure on the exchange rate. Market commentary also noted that lower crude prices and easing inflation concerns could support the rupee at weaker levels.
