The rupee witnessed a range-bound trading in early trade on Thursday as a firm American currency and concerns about hawkish US Fed offset the support from positive domestic equities.

At the interbank foreign exchange, the domestic unit opened at 79.53 against the dollar, then touched 79.47 in initial deals, registering a gain of 5 paise over its previous close.

On Wednesday, the rupee declined by 35 paise to close at 79.52 against the US currency.

The dollar index, which gauges the greenback's strength against a basket of six currencies, rose 0.06 per cent to 109.72.

Brent crude futures, the global oil benchmark, fell 0.11 per cent to USD 94 per barrel.

In the domestic equity market, the 30-share BSE Sensex was trading 275.51 points or 0.46 per cent up at 60,622.48. Similarly, the broader NSE Nifty rose 36.15 points or 0.2 per cent to 18,039.90.

Foreign Institutional Investors (FIIs) were net sellers in the capital markets, as they offloaded shares worth Rs 1,397.51 crore on Wednesday, according to provisional data.

"Asian currencies are still on the weaker side against USD which will not allow the rupee to gain much against the dollar. The range for the day is expected between 79.30 to 79.80 as the market braces for a 75 basis points rate hike by FED," said Anil Kumar Bhansali, Head of Treasury, Finrex Treasury Advisors.

India's trade deficit was wider though export figures were also revised to slightly higher. "Trade deficit still remains a matter of concern for the country," Bhansali said.

India's exports rose marginally by 1.62 per cent to USD 33.92 billion, while the trade deficit more than doubled to USD 27.98 billion in August due to increased crude oil imports, the commerce ministry data showed on Wednesday.

The revised data showed that imports rose by 37.28 per cent to USD 61.9 billion in August this year.
