By Staff Reporter MUTARE: A Renowned economist says Treasury could soon be forced to print more money to provide liquidity to the Grain Marketing Board (GMB) to purchase grain expected to be worth $60 billion. Prosper Chitambara, an economist with the Labour and Economic Development Research Institute of Zimbabwe (LEDRIZ) said although the move to increase money supply could trigger inflationary pressures, it was, however, a positive move for grain exports. He said the grain exports will earn Zimbabwe the much-needed foreign currency and enhance food security. Chitambara was speaking at a public lecture on the state of the economy to media students in the eastern border city of Mutare.
