The domestic currency has spurted by 425 paise or 6.28 per cent in last five straight sessions.
The rupee had gained 46 paise to close at 63.38 yesterday against the dollar on the back of fresh RBI steps to boost foreign fund inflows and hopes of a diplomatic solution in Syria.
Dealers said besides increased capital inflows driven by recent measures announced by the RBI, a higher opening in domestic equity market and dollar's weakening against major currencies overseas helped the rupee rise.
