Egypt's two biggest state-owned banks have collected 121 billion Egyptian pounds ($7.7 billion) from a new high-yield savings certificate they introduced in March, officials from the two banks were quoted as saying on Sunday. The one-year certificates, launched on March 22, carry a 15 percent yield. The National Bank of Egypt's deputy chairman said it had collected 82 billion pounds while Banque Misr's chairman said it had gathered 39 billion pounds, state news agency MENA reported. The certificates appear designed to bolster incomes while reducing inflation pressure and dollarisation following the coronavirus outbreak, analysts say. ($1 = 15.7700 Egyptian pounds)
