The Indian rupee gained the most in three weeks on Thursday, boosted by the US Federal Reserve's decision to refrain from tapering off its massive monetary stimulus
just yet, but the central bank's policy on Friday will be the next key trigger.
The partially convertible rupee closed at 61.77/78 per dollar compared to its close of 63.38/39 on Wednesday.
The rupee rose 2.6 per cent on day, its biggest single day rise since August 29.
