Egypt's central bank kept the pound steady at LE7.53 to the dollar at a foreign exchange auction on Sunday while the currency strengthened on the parallel market.
The bank said it had offered $40 million and sold $38.2 million at a cut-off price ofLE 7.5301 per dollar, unchanged from its last auction held on Thursday.
The central bank has now kept the official exchange rate steady for more than a month after letting the pound weaken in an effort to wipe out black-market trading.
Black-market traders said activity had fallen dramatically because of that step and a cap the central bank put in place in February on the amount of dollars that could be deposited in banks.
The limit on deposits discourages use of the black market by depriving those who want to exchange dollars outside official channels of a place to keep their funds.
One trader said the dollar was selling for LE7.60 on the black market on Sunday, much stronger than the rate of 7.67 a week ago.
The rates at which banks are allowed to trade dollars are determined by the results of central bank sales, giving the bank effective control over official exchange rates.
