The Egyptian pound was held steady by the central bank which sold $37.8 million at a cut-off price of LE7.7301 per dollar on Thursday, but weakened on the parallel market.
The official cut-off price remained unchanged from last Tuesday's dollar sale but one trader said the dollar changed hands at LE8.05 in the parallel market, weaker than the LE8.03 to the dollar rate on Tuesday.
Egypt has sought to tame a once-thriving currency black market with measures such as a cap on dollar-denominated bank deposits.
The central bank gave permission in January to trade dollars up to LE0.10 above or below the official rate, with currency exchange bureaus allowed to trade at 0.15 pounds above or below the official rate.
The central bank had kept the pound at 7.5301 for five months until July, when it was allowed to slide to 7.6301. On July 5, the bank let it slip a further LE0.10.
Allowing the pound to weaken in a controlled way could boost exports and attract further investment, but it also raises Egypt's already large bill for imported fuel and food staples.
