The rupee witnessed range-bound trading against the US dollar in early trade on Monday, weighed down by a negative trend in domestic equities and the strength of the American currency in the overseas market.

Forex traders said the safe-haven dollar gained ground amidst heightened concerns in West Asia.

At the interbank foreign exchange, the rupee opened at 83.24 against the dollar, then touched 83.23, registering a rise of 4 paise over its previous close.

On Friday, the rupee declined 2 paise to settle at 83.27 against the US dollar.

The dollar index, which gauges the greenback's strength against a basket of six currencies, advanced 0.26 per cent to 106.32.

Brent crude futures, the global oil benchmark, advanced 3.69 per cent to $SD 87.70 per barrel.

According to CR Forex Advisors MD-Amit Pabari, market sentiment turned delicate following clashes between Israeli forces and Hamas over the weekend, coinciding with a surprise attack by militants on Israel, marking the deadliest day of violence in the region in half a century.

"Global tensions propel safe-haven dollar, while RBI's vigilant stance sparks a currency market tug-of-war," Pabari added.

The USD/INR pair is encountering notable resistance at the 83.30 level, while concurrently finding support around 82.80. This creates a scenario akin to a tug-of-war, where a breach of either pivotal level could trigger a significant movement, with an estimated range of approximately one rupee in either direction, he said.

In the domestic equity market, the 30-share BSE Sensex declined 274.33 points or 0.42 per cent to 65,721.30. The broader NSE Nifty fell 84.10 points or 0.43 per cent to 19,569.40.
