Nigeria's central bank is no mood to devalue the naira given the risks to inflation from a weaker currency, its spokesman said on Friday, potentially delaying investment flows into Africa's biggest economy, Reuters reported. The central bank (CBN) said in a statement it believed the 22 percent depreciation in the naira after it scrapped the official foreign exchange window "is optimal at this time" and the bank would not be pressured into "desperate measures". -- SPA 21:58 LOCAL TIME 18:58 GMT تغريد
