The Two Trillion Dollar Gap
According to World Bank figures for 2025, Nigeria's economy is valued at USD 291 billion when converted at the official exchange rate. However, when measured by what money can actually buy locally, the economy is worth USD 2.3 trillion.
This leaves a gap of nearly USD 2 trillion, representing the country's vast unseen market. This informal space is powered by roadside traders, tailors, smallholder farmers, and neighborhood mechanics.
The size of this sector varies by source. The National Bureau of Statistics estimates that the informal economy makes up 41 percent of the total, while the International Monetary Fund places it as high as 65 percent or more.
Why Forced Formalisation Fails
Traditional policies often focus on forcing these informal businesses to register and pay taxes. However, private equity investor Frank Nnamka argues that this approach rarely succeeds on its own.
Informal operators only step into the formal system when the benefits outweigh the costs of compliance. They seek tangible advantages such as access to credit, larger customer bases, or legal protection.
A clear example of this is the rapid adoption of digital payment platforms in Nigeria. Millions of citizens transitioned to digital channels not for regulatory compliance, but because the tools were highly useful.
Unlocking Latent Consumer Value
For businesses and investors, this massive gap means the addressable consumer market is far larger than nominal GDP suggests. Companies in telecom, cement, and packaged foods scale successfully because they tap into the USD 2.3 trillion purchasing power.
The primary opportunity lies in building bridges to formality. Businesses that offer embedded credit, digital payments, and simple bookkeeping tools can turn informal transaction histories into bankable credit profiles.
As structural challenges like unreliable power, difficult logistics, high inflation, and high borrowing costs improve, this latent value will convert into formal revenue.
