Retail inflation in November fell to a two-year low of 3.63 per cent after the Centre's demonetisation drive dented consumer spending on various food items, including vegetables.
This is the lowest level since November 2014 when the retail inflation came in at 3.23 per cent.
Forex dealers said a higher opening in domestic equities and dollar's weakness against some currencies overseas supported the local unit.
Meanwhile, the benchmark Sensex advanced 38.52 points, or 0.14 per cent, to 26,736.34 in morning trade.
