The median overnight rate on the Egyptian pound rose slightly to 10-3/4 percent on Sunday from 10-1/2 percent on Thursday as bankers awaited the result of a treasury bill auction.
"It looks like a stable market," one banker said, adding that rates were little changed from Thursday. The central bank was due to auction 91-day treasury bills worth one billion pounds ($161 million) later on Sunday.
Four of eight banks contacted by Reuters had dealt overnight at rates ranging between 10-1/2 and 11-1/4 percent. Overnight rates on Thursday ranged between 10 and 11 percent.
Six of the banks had dealt for one week at rates of between 10-5/8 and 11-3/4 percent. One-week rates ranged between 10 and 11-1/2 percent on Thursday.
The overnight CAIBOR rate was unchanged from Thursday at 11.0476 percent. The one-week CAIBOR slipped to 11.5476 percent from Thursday's 11.6071.
On the official foreign exchange market, the pound strengthened against the dollar to last trade at a midrate of 6.18 in banks and 6.20 in foreign exchange bureaux, compared to Thursday's close of 6.21.
Three market sources said the dollar would buy between 6.25 and 6.28 pounds on the black market, around recent levels.
