Snapping a six-session losing streak, the Indian rupee appreciated by 20 paise to Rs 45 per US dollar in early trade today. Forex dealers said, dollar weakness against the euro and other currencies overseas after the US Federal Reserve announced that it will keep rates low for at least two years and a strong recovery in the domestic stock market helped the rupee to strengthen in early trade today. The rupee had depreciated by 23 paise to close at a nearly 10-week low of Rs 45.21 against the dollar in Tuesday's session.
