The Central Bank of Egypt (CBE) sold $75 million to banks on Wednesday at its third foreign currency auction, banking sources said. The auctions are part of a shift in currency policy announced by the CBE and designed to conserve the country\'s foreign reserves, which it said had fallen to a critical level. The Egyptian pound continued falling against the US dollar on Wednesday to stand at a record high of EGP 6.422 for selling and EGP 6.38 for buying.
