This represents a substantial weakening of the Egyptian pound, which was bid in the interbank market on Sunday at 6.185 pounds to the dollar.

The bank had offered $75 million at the auction.

The central bank said the weighted average bid price at the auction was 6.2526 pounds to the dollar. On Saturday, the bank said reserves, which stood at about $15 billion at the end of November, had fallen to a critical level.
