"The demand for foreign exchange to support our unbridled demand for imports undermines and weakens the value of the cedi," he said.As part of the measures to get the economy back in shape, Ofori-Atta announced a freeze on new tax waivers for foreign companies, a review of tax exemptions for mining, oil and gas companies and a reduction in the fuel allocation to government appointees.“What could be done more significantly in terms of minimizing government expenditure has to do with the corruption in the system and then financial malfeasance," Amartey said.Meanwhile, the Vice-President Mahamudu Bawumia announced on Facebook that Ghana is working on a new policy, effective next year, to buy oil products with gold rather than U.S. dollar reserves as part of the government measures to strengthen the cedi.He added: "The government of Ghana will buy gold locally with cedis through the Bank of Ghana (financier) and then exchange the gold for fuel (oil) in a barter form, for example, with the government of UAE.""
