IMF calls on Nigeria to lift foreign exchange curbs

The International Monetary Fund (IMF) called on Wednesday for Nigeria to lift foreign exchange curbs and let the naira reflect "market forces" more closely, also urging more fiscal discipline and structural reform to bolster growth.

President Muhammadu Buhari has rejected a naira devaluation and backed hefty restrictions imposed by the central bank to prevent a collapse of the naira as Africa's biggest economy is whacked by a slump in oil revenues, its lifeblood.

Companies have laid off thousands, cut production and even closed operations as they struggle to get enough dollars to pay for imported spare parts and raw materials.

The naira is trading as much as 40 percent below the official rate on the black market. Devaluation would encourage investment and make domestically produced goods more affordable.

"The exchange rate should be allowed to reflect market forces more and restrictions on access to foreign exchange removed, while improving the functioning of the interbank foreign exchange market," the Washington-based fund said in a statement, after consultations with top officials in Nigeria.

Currency curbs had "significantly" affected parts of the private sector and the economic outlook for Africa's top oil producer was "challenging", it said.

Nigeria needs to import anything from milk to machines as authorities have failed to end its dependency on oil, a fact Buhari wants to change but which business leaders say will be impossible to achieve if plants cannot import raw materials.

The IMF also said it expected the West African nation to grow by 3.2 percent this year, below the official forecast of 3.78 percent. It urged boosting non-oil revenues, raising infrastructure spending and collecting more taxes.
