Mumbai: The rupee stayed on the upward track for the second straight session and appreciated 6 paise to 83.37 against the US dollar in early trade on Wednesday boosted by sustained inflow of foreign capital and firm equity markets.

The local unit, however, faced resistance due to a stronger American currency and higher crude oil prices overseas, forex traders said.

At the interbank foreign exchange market, the local unit opened strong at 83.39 and gained further to 83.34 against the greenback in initial deals. It later traded at 83.37 against the American currency, registering a rise of 6 paise from its previous close.

On Tuesday, the rupee had settled 12 paise higher at 83.43 against the US dollar.

Meanwhile, the dollar index, which gauges the greenback’s strength against a basket of six currencies, was trading marginally higher by 0.02 per cent at 104.90.

Analysts said the dollar index fell initially as the US data showed the growth in retail sales was lower than expected, though the currency recovered with May industrial output numbers topping the forecast.

Officials of the US Federal Reserve indicated a hawkish stance to continue, dousing hopes of an interest rate cut until December.

“The dollar eased against the euro on Tuesday after US retail sales data showed slower growth, suggesting potential Federal Reserve rate cuts later this year,” said Anand James, Chief Market Strategist, Geojit Financial Services.

Brent crude futures, the global oil benchmark, rose 0.02 per cent to USD 85.35 per barrel.

In the domestic equity markets, the 30-share BSE Sensex rose 199.63 points, or 0.26 per cent, to 77,500.77 points. The broader NSE Nifty climbed 25.55 points, or 0.11 per cent, to 23,583.45 points.

Foreign Institutional Investors (FIIs) were net buyers in the capital markets on Tuesday, as they purchased shares worth Rs 2,569.40 crore, according to exchange data.

Analysts attributed the strong FII buying to the firm domestic macroeconomic outlook and a sharp fall in the US treasury yield.
