Mumbai, Jan 13 (Agencies): The Indian Rupee appreciated by six paise to Rs 45.07 a dollar at the Interbank Foreign Exchange market on Thursday, boosted by the greenback's weakness against euro and other major currencies.

Forex dealers said that dollar's weakness against other major currencies kept the rupee's sentiment firm. However, lower opening at the stock markets capped its gains.

The rupee closed three paise up to a nearly one-week high of Rs 45.13/14 a dollar on sustained US currency selling by some banks exporters.

Meanwhile, the Bombay Stock Exchange index Sensex was down by 116.95 points to 19,417.15 points in the opening trade on Thursday.
