Mumbai: The rupee reversed its nine-day upward movement and depreciated 11 paise to 82.97 against the US dollar in early trade on Tuesday, tracking a strong American currency against major overseas rivals and subdued equity market sentiment.
Some inflow of foreign funds supported the Indian currency which was weighed down due to volatile crude oil prices, forex traders said.

On Monday, the rupee settled with a gain of 9 paise at 82.86 against the US dollar. This was ninth consecutive day of gain for the Indian currency.
In the last nine trading sessions, the local unit added 46 paise since the level of 83.32 against the dollar recorded on January 2.
Meanwhile, the dollar index, which gauges the greenback's strength against a basket of six currencies, was trading 0.31 per cent higher at 102.63 on Tuesday.

Retail inflation also soared to a four-month high of 5.69 per cent in December, while industrial production fell to an eight-month low of 2.4 per cent in November, according to the government data released on Friday.
