CAIRO - Egypt's central bank said it will offer 6 billion Egyptian pounds in repurchase agreements in the money market on Tuesday at a fixed rate of 9.25 per cent. The central bank introduced the weekly seven-day repo agreements on March 22 to help steady short-term interest rates in the wake of the political and economic unrest that led to former president Hosni Mubarak stepping down. Last week, the central bank offered and accepted repos worth 6 billion Egyptian pounds.
