The Central Bank of Egypt said the country's foreign currency reserves are at a "critical" minimum level, AP reported. The bank said the reserves are at the minimum level needed to pay Egypt's international obligations. It did not give a current figure. In statistics from November, the reserves stood at $15 billion, less than half before last year. The bank said in a statement Saturday that it has introduced a new auction system for buying and selling U.S. dollars after a rush by Egyptians to sell the pound in exchange for dollars over concerns of devaluation. Reserves have tumbled since foreign investment dried up amid the country's turmoil the past two years. Much of the reserves have gone toward propping up the currency.
