Recently, the CBN Governor, Godwin Emefiele, said restriction on global travel by land and air, along with the slowdown in commercial activities, led to a significant reduction in the demand for crude oil, which contributed to a 65 per cent decline in crude oil prices between January and May 2020.
“The drop in crude prices, along with OPEC reduction of Nigeria’s production quota, led to a significant decline in our foreign exchange earnings, along with a more than 60 per cent decline in revenues due to the federation account,” he said.
Like other emerging market countries and countries reliant on oil exports, he said, the decline in crude oil earnings as well as the retreat by foreign portfolio investors significantly affected the supply of foreign exchange into Nigeria.
He said in order to adjust for the decrease in supply of foreign exchange, the naira was devalued from N305/$ to N360/$ and subsequently to N380/$.
