KARACHI (Reuters) - In the currency market, the rupee firmed to close at 84.23/26 to the dollar compared with 84.26/44 on Saturday, amid soft demand for the U.S. currency. There was pretty low demand for the dollar from importers today and some selling was also seen from exporters, which supported the rupee, said a brokerage dealer. Dealers said the rupee was expected to move in a narrow band in days ahead, though some downward pressure may be seen as import payment pressure grows.
