On Friday the Nigerian Bureau of Statistics revealed that the country's economy shrank by 0.4% year-over-year in the first quarter — way worse than expected.

Economists were expecting the country to grow by 1.8% year-over-year, according to the Bloomberg consensus.

And now analysts aren't feeling too good about the situation going forward.

"We have long warned of a slow-burning crisis in Nigeria," Capital Economics' Africa economist John Ashbourne said. "It now seems that this view was too optimistic: the country is headed into a full-blown economic crisis."

Nigeria continues to suffer from numerous economic headaches, including lower oil prices and the government's controversial foreign-exchange and price-control policies (which analysts have more or less deemed a failure).

The biggest drop in growth was in Nigeria's manufacturing sector, which Ashbourne wrote was crushed by the country's FX policies.

"This is very bad news for Nigeria's government, which has justified the current FX system as a method of promoting non-oil industries," Ashbourne said. "It is now clear that these policies have — as we'd long argued — made a bad situation worse."

Still, the scariest thing about this latest gross-domestic-product number is that it doesn't factor in any of the debilitating problems Nigeria has seen in the second quarter, including but not limited to the fuel-shortage crisis and some of the oil-production disruptions by the Niger Delta Avengers.

In short, Ashbourne concluded grimly, "the worst is yet to come."
