Nigeria invests roughly a third of its entire economy, yet its growth rate lags far behind comparable emerging markets, according to a new op-ed by private equity investor Frank Nnamka. The piece, titled "Nigeria's trillion-dollar ambition has a returns problem," argues that the country's central economic challenge is not a lack of investment but the poor returns generated from it.
Same Investment, Different Growth
Data from the National Bureau of Statistics (NBS) shows Nigeria's investment-to-GDP ratio has hovered between 32 and 35 percent in recent years. This is almost exactly the level seen in India, Indonesia, and Vietnam. However, those countries have consistently grown at 6 to 7 percent annually for a generation, while Nigeria has managed only about 4 percent—and even less on a per capita basis, given its rapidly rising population.
"Same effort. Very different result," Nnamka writes, highlighting the stark contrast. He notes that even if the International Monetary Fund's lower estimate of 17 percent is used, the puzzle remains: Nigeria's growth yield from investment is significantly below that of its peers.
The Returns Problem
The core issue, Nnamka argues, is not how much Nigeria invests but what it gets back. The relevant measure is growth—how much additional output each naira of investment produces. On this metric, Nigeria is far behind.
"So Nigeria's problem is not how much it invests. It is what it gets back," he states. The country's investment returns are eroded by a range of structural inefficiencies.
Where the Returns Go
Much of Nigeria's investment is effectively spent "standing in place," Nnamka explains. Businesses are forced to build their own power because the national grid is unreliable. They contend with congested ports and poor roads, bearing costs that competitors in other countries never face. Insecurity in some regions and unpredictable policy shifts further drain returns.
"Investment that replaces a broken grid keeps the lights on. It does not make the country richer," he writes. This means a significant portion of capital is used merely to compensate for infrastructural deficits rather than to drive genuine economic expansion.
Reframing the Trillion-Dollar Task
This analysis fundamentally changes what Nigeria's ambition to become a trillion-dollar economy requires. Nnamka contends that Nigeria does not need to summon the will to invest more—it already invests a great deal. Instead, it must make every naira go further by fixing the shared foundations that are swallowing returns.
"Reliable power, smoother logistics, greater security and steadier policy would lift the return on every naira already invested, all at once. It is the cheapest growth the country can buy," he argues.
Implications for Investors
For those putting money to work in Nigeria, this reframes what to look for. The scarce resource is not capital but return. Businesses that succeed are those that either remove a constraint draining everyone else's returns—in power, logistics, payments, or storage—or are shielded from those constraints by design.
"Returns rise fastest wherever the foundations improve," Nnamka notes. He advises that the developments worth watching are not headline growth targets but the quieter fixes to power, ports, and policy. "In Nigeria, you underwrite the environment as much as the business," he adds.
Can Nigeria Make It Count?
Nnamka concludes with a sober assessment: Nigeria has the effort and, by its own figures, much of the capital. What it lacks are the conditions that turn capital into growth. He paints a vivid picture: "The country is not standing still. It is running hard with the brakes on. The money is being spent. The task is to make it count."
This op-ed is part of a series exploring whether and how Nigeria can become a one trillion-dollar economy. The next installment will examine whether Nigeria is preparing its people to power the growth.
