The focus is now squarely on the US Federal Reserve's meeting on September 17-18 at which it is expected to announce a trimming of its bond buying.
Emerging Asian currencies have been under pressure with investors trying to guess how much the Fed will cut its monetary stimulus next week. However, disappointing US data recently has led to hopes that the Fed may limit its stimulus withdrawal.
India is particularly vulnerable to any tapering as it suffers from both a large current account deficit and a fiscal gap.
Easing concerns over any imminent strike on Syria by the United States have also helped risk assets.
"I do not think that the Fed will be in a rush to taper as data out of US has not been consistent. A lot of it has been factored into recent emerging market FX," said Subramanian Sharma, director at Greenback Forex.
"However, the rupee's recent recovery has been too fast and too big. I do not think it will sustain based on fundamentals and it may fall again to 64.50 levels."
The rupee ended at 63.49/50 to the dollar versus 63.50/51 last close. Dealers cited some central bank intervention in late trading.
It gained 2.76 per cent in the week, its best since June 2012.
The currency has been boosted by strong foreign fund buying in equities totalling over $1 billion in the six sessions to Thursday.
However, domestic concerns persist, with growth outlook still remaining muddled. The Prime Minister's Economic Advisory Council sharply cut its fiscal year growth forecast to 5.3 per cent from 6.4 per cent and said meeting the budgeted fiscal deficit of 4.8 per cent may be a challenge.
Reserve Bank of India chief Raghuram Rajan will detail his first monetary policy review on September 20, which will be closely watched to see whether the central bank will give any signs of when it plans to begin withdrawing its cash tightening steps it launched in mid-July to stabilise the rupee.
In the offshore non-deliverable forwards, the one-month contract was at 64.33 while the three-month was at 65.61.
In the currency futures market, the most-traded near-month dollar/rupee contracts on the National Stock Exchange, the MCX-SX and the United Stock Exchange all closed around 63.79 with a total traded volume of $3 billion.
