Nigeria’s budget ₦54.99 trillion is under pressure as crude oil prices fall from $70 to about $66 per barrel—representing a roughly 5.7 percent revenue decline. The shortfall may reduce fiscal space for infrastructure, social programs, and debt servicing in a petroleum-dependent economy. The shift symbolizes how global energy markets directly impact Nigeria’s development trajectory. It underscores the need for diversification to buffer fiscal shocks. And it may force policymakers into tighter budget planning amid volatile oil demand.
