The rupee tumbled 11 paise to close at a fresh lifetime low of 77.85 (provisional) against the US dollar on Friday as a sell-off in domestic equities and stronger greenback overseas weighed on investor sentiment.

Persistent foreign capital outflows, elevated global crude oil prices, and risk-averse sentiments also impacted the domestic unit, forex traders said.

At the interbank foreign exchange market, the local currency opened at 77.81 and witnessed an intra-day high of 77.79 and a low of 77.87 against the US dollar.

The local unit finally settled at its all-time low of 77.85, down 11 paise over its previous close of 77.74.
