The rupee marginally rose by one paise to Rs 45.37 a dollar in early trade at the Interbank Foreign Exchange today, propelled by gains made by Asian currencies against the greenback.

Forex dealers said dollar's weakness in the Asian markets helped the rise of rupee, but weak opening on the stock market capped its gains.

The rupee had declined by 13 paise to its three-week low at Rs 45.38/39 a dollar in the previous session on Friday, following a steep fall in equity markets amid capital outflows.

Meanwhile, the Bombay Stock Exchange benchmark Sensex tumbled 221.58 points down to 19,470.23 points in the opening trade today.
