Egypt's central bank said on Monday it intended to reintroduce deposit operations as a way to absorb excess liquidity, starting on Tuesday, in a monetary tightening move that economists said could help fight inflation and support a weakening currency.

The central bank said the deposits would have a seven-day maturity with a fixed interest rate of 10.25 per cent. It added that repo operations would be "suspended unless conditions warrant otherwise."

Hit by political unrest that has hammered the economy, the Egyptian pound has lost 9 per cent of its value against the dollar since late December when the central bank brought in a new system of dollar auctions that allowed the currency to weaken.

The pound is trading weaker still on the black market.

The central bank raised interest rates on March 21 in an effort to stem the pound's decline and curb inflation. It lifted both its main rates by 50 basis points, taking the overnight deposit rate to 9.75 per cent and the overnight lending rate to 10.75 per cent.

"They are starting to tighten monetary policy," said Mona Mansour, chief regional economist at CI Capital in Cairo. "Mainly it is to fight inflation."

Mohamed Abu Basha, the economist at EFG-Hermes, said, "This is liquidity management because lately there has been excess liquidity in the Egyptian pound because of dollarisation."
