Fresh dollar demand from banks and importers in view of weak equity market amid firm dollar overseas affected the rupee value, a forex dealer said. The BSE 30-scrip benchmark Sensex declined 30.94 points or 0.18 per cent to 17,063.57.
Earlier, it was down 62 points. In New York, the dollar extended gains against major currencies last Friday as investors reacted to weak data on US consumer sentiment that weighed on equities. Meanwhile, crude oil prices slid in Asian in early trade today.
