The rupee entered its third week of rally and appreciated 6 paise to 83.46 against the US dollar in early trade on Monday, tracking positive momentum in domestic equity markets amid a massive inflow of foreign funds.
However, an upward movement in the crude oil prices and a strengthening greenback against major overseas rivals capped a sharp rise in the Indian currency, forex traders said.
At the interbank foreign exchange market, the Indian currency opened at 83.44 and fell to 83.49 before trading again at 84.46 against the greenback, registering a gain of 6 paise higher than its previous closing level.
The local unit gained 13 paise to settle at 83.52 against the US dollar on Friday.
The Indian currency has been on a recovery path since September 11 when it had settled at 83.99 against the American currency, a tad higher than the lowest level of 84.09 recorded on August 5.
The upward move of the Indian currency was attributed to the US Federal Reserve's decision to reduce benchmark interest rate by 0.50 per cent last week and positive commentary by the Fed chair about the American economy.
