The partially convertible rupee was trading at 79.24 per dollar by 0837 GMT, its strongest level since July 7 and higher versus its close of 79.7550 on Thursday.

The greenback shed around 1% against the yen, taking the dollar index - which measures the currency against six majors - down by 0.4% and marking its worst performance since early July.

Traders now shift their focus to the Reserve Bank of India's monetary policy meeting next week, where chances of a 35 basis point (bp) hike seem more likely than a 50 bp hike.
