The Indian rupee appreciated by 19 paise to 45.15 rupees against the US dollar in early trade today. Sustained selling of dollars by banks and exporters due to weakness of the greenback in global markets, mainly boosted the rupee value against the dollar, a forex dealer said. Meanwhile, crude oil prices dipped to 87.43 US dollars a barrel in the Asian trade today ahead of a meeting between German and French leaders on how to deal with the eurozone's spiralling debt crisis.
