KARACHI : In the currency market, the rupee ended almost flat at 90.68/73 to the dollar , compared with Wednesday's close of 90.68/72 but dealers expect pressure to continue as international oil prices ended on an eight-month high on Wednesday. The rupee touched a record low of 91.28 to the dollar on Jan. 9, pressured by worries about higher payments for oil imports and the country's overall economic health.
