The rupee declined 7 paise to close at 83.35 (provisional) against the US dollar on Friday as a strengthening American currency overseas and a selloff in domestic equities weighed on the local unit.

Besides, rising crude prices in the international market and risk-averse sentiment dragged the local unit down, forex traders said.

At the interbank foreign exchange market, the local unit opened strong at 83.30 and moved in the range of 83.30-83.36 during the session.

The local currency finally settled at 83.35 (provisional) against the dollar, registering a fall of 7 paise from its previous close.

In the previous session, the rupee closed at 83.28 against the US dollar.

"Indian Rupee declined slightly on weak domestic markets and a surge in crude oil prices. We expect the rupee to trade slightly weak on renewed geopolitical tensions in the Middle East and weakness in domestic equities.

"Rising crude oil prices and FII outflows may further put pressure on the rupee. However, any intervention by the RBI may support the rupee at lower levels. We expect USDINR to trade in the range of 83.10-83.60," Anuj Choudhary, Research Analyst, Sharekhan by BNP Paribas, said.
