The Central Bank of Egypt (CBE) on Tuesday announced that international reserves decreased to $27.2 billion by the end of May, from US$28.02 billion at the end of April. According to the CBE online database, international reserves of foreign currencies dropped by US$9 billion since the end of December 2010, when it was US$36.1 billion. Egypt's reserves of hard currencies have also dropped since the state of instability began with the security failure during the January 25 revolution, which affected trade and industry.
