Part Three.
Where the Dollar Goes After It Arrives
Parts One and Two followed the dollar before it reached the Central Bank. The invisible IOU attached to the gross reserve figure. The five rooms it passes through, each one taking something. The NNPC parallel economy. The subsidy that changed its name. The oil that never arrives because it was stolen before it was pumped.
By the time the dollar survives all of that and reaches the CBN, it is already a smaller dollar. Already committed, in part, to obligations that do not appear in the number you are shown.
Part Three follows what happens next. Because the pressure does not stop when the dollar arrives. It begins a different kind of pressure. Four drains, each one structural, each one running simultaneously, each one invisible in the headline figure.
The first drain is the largest. Most people do not know this.
The single biggest claim on Nigeria's foreign exchange is not food imports. It is not fuel. It is debt.
In 2025, Nigeria spent several billion dollars servicing its external debt. By some estimates, debt service accounted for over two-thirds of total FX outflows, meaning two-thirds of every dollar leaving Nigeria's external accounts went straight to foreign creditors rather than to imports, investment, or reserve accumulation. To put that in domestic terms: in 2026, debt service is projected to consume close to ₦15.8 trillion. Nearly half of expected government revenue. Not half of the discretionary budget. Half of everything the government expects to collect.
Nigeria's external debt stood at approximately $52 billion by early 2026. That number was built across decades, by successive administrations, through Eurobonds and bilateral loans and multilateral borrowing, much of it taken on without corresponding investment in the capacity to earn enough foreign currency to repay it comfortably.
This is not a crisis of the current administration. It is accumulated weight. It was accumulating before Tinubu. Before Buhari. The bill does not care who is in office. It arrives on schedule regardless of oil prices, regardless of who the CBN governor is, regardless of what reforms are announced.
A former Vice President calling this poor management is like calling a man in debt poor because he spends too much. The spending is not the cause. The structure is the cause. The structure was built across generations and it will take generations to unwind.
Every dollar that leaves Nigeria to service external debt is a dollar that cannot become a reserve. Cannot defend the naira. Cannot pay for imports. Cannot signal credibility to investors. It is gone before it can do any of those three jobs.
The second drain is the one Nigeria is most publicly embarrassed about. And the least honest about.
Nigeria is an oil exporter that has historically refined very little of its own crude. For decades, it pumped oil out of the ground, sold it abroad, then bought back the refined product at a markup, losing value at both ends of the same transaction. The Dangote Refinery changed that picture when it came online in 2024, and it is now refining crude, including imported crude, at meaningful volumes. But it is operating well below its nameplate capacity. And the state refineries in Port Harcourt, Warri, and Kaduna, despite rehabilitation efforts, are still not producing at the levels Nigeria needs. The import dependency has not ended. It has partially reduced. With a nameplate capacity of 650,000 barrels per day, it is one of the largest refineries in the world. When President Tinubu cut the subsidy in May 2023, part of the logic was that domestic refining was coming. The import dependency would end. The dollars spent on fuel imports would stay in Nigeria.
The refinery came online in 2024. As of early 2026, it is operating well below its nameplate capacity.
Why? Several things are happening simultaneously and not all of them are fully public.
There have been disputes between NNPC and Dangote over crude supply and pricing. The refinery was designed to process Nigerian crude, but the pricing arrangements for that crude have been contested. At various points, the refinery has processed foreign crude because domestic supply was not available on terms that worked.
There are unresolved questions about the domestic fuel pricing framework. If the government has not fully deregulated petrol prices, the refinery cannot sell at market rates. A refinery that cannot price freely cannot operate freely.
And there are questions about off-take arrangements that are not answered in any public document.
The refinery's potential, if it reaches full capacity, is to save Nigeria $10 to $15 billion a year in fuel import costs. That is not a marginal improvement. That would change the entire reserve picture. A persistent current account deficit driven by fuel imports would narrow or close. Billions of dollars that currently leave Nigeria every year would stay inside it.
Whether that potential is realised depends on decisions being made right now in rooms that are not public. The pricing framework. The crude supply arrangements. The relationship between NNPC, Dangote, and the government. These are the decisions that will determine whether the refinery becomes the structural fix it was built to be, or whether it becomes another large asset operating at a fraction of its capacity while the import dependency continues.
That question is one of the most consequential open questions in Nigerian economic policy. It is almost entirely absent from public debate.
The third drain is the one the CBN controls. But controlling it does not make it painless.
In 2025, the CBN sold an estimated $7.8 billion from reserves to stabilise the exchange rate. Nearly half of that occurred in a three-month window of intense depreciation pressure.
To understand why, you need to understand what the CBN is defending against and what it is defending with.
When the naira comes under selling pressure, the CBN has two options. It can let the naira fall. Or it can sell dollars from reserves to buy naira, reducing the supply of naira in the market and supporting the price.
Letting the naira fall has an immediate human cost. Every imported good becomes more expensive. Petrol. Medicine. Food. The price of a cup of rice in Grace's neighbourhood moves within days of a significant naira depreciation. The CBN is not a humanitarian institution but it operates in a political environment, and the political cost of allowing a currency to fall sharply is real and immediate.
So the CBN intervenes. It sells dollars. It buys naira. It holds the line.
Here is the cruelest part of that calculation. When a central bank defends a currency aggressively and visibly, it tells the market two things simultaneously. First, that it believes the currency is worth defending. Second, that it is willing to spend reserves to defend it. The second signal attracts speculators who bet that eventually the bank will run out of reserves to spend. The defence creates the conditions for the next attack. The more you spend, the more pressure arrives. There is no clean exit from this dynamic once you are inside it.
And the dollars the CBN spends in this defence do not come only from the gross reserve figure. They come, increasingly, from instruments that do not appear in the gross figure at all. Forwards. Swaps. Commitments to deliver dollars in the future, booked today, reducing the net reserve position without moving the headline number.
Grace's cup of rice is one of the reasons the CBN spends those dollars. The CBN spends those dollars to prevent Grace's cup of rice from becoming half a cup. But those spent dollars are part of why the headline reserve figure is not what it appears to be.
The CBN is spending reserves to protect ordinary Nigerians from the immediate consequences of a falling currency, while that spending reduces the buffer that protects ordinary Nigerians from the medium-term consequences of a depleted reserve position. There is no right answer. Every option is expensive. The question is only which expense arrives first.
The fourth drain is the one nobody models publicly. But everyone in the system knows it is there.
Nigeria's next general elections are in 2027. In the twelve to eighteen months before a Nigerian general election, pressure on foreign exchange reliably increases. Political actors need dollars. For foreign travel. For campaign infrastructure. For international consultants. For purposes that are sometimes less describable but no less real.
Not all of this is corruption. Some of it is simply the cost of running a modern political campaign in a country where a significant portion of elite activity is priced in dollars. But none of it is formally tracked. None of it appears in any official statistic. And all of it adds pressure to a reserve position that is already under pressure from three structural drains running simultaneously.
In April 2026, some Nigerian analysts and market observers noted a correlation between the reserve decline over several weeks and election-related spending pressures building ahead of 2027. The CBN made no comment on this. No official body tracks or discloses it. The political drain on foreign exchange is one of the most consistent and least discussed features of Nigeria's electoral cycle.
It will intensify. It is already intensifying. And it will do so against a backdrop of debt service obligations that do not pause for elections, fuel import costs that do not pause for elections, and currency defence requirements that do not pause for elections.
Now look at all four drains together.
Debt service consuming the majority of every international dollar spent. Fuel imports costing billions despite a refinery sitting below capacity. Currency defence burning through reserves and forward commitments simultaneously. Election spending adding pressure no official body will acknowledge.
None of these drains can be turned off quickly. The debt is structural and decades old. The refinery situation depends on decisions and negotiations that are not public. Currency defence is a trap once entered. The electoral cycle is a calendar fact.
This is why the Vice President's framing, poor management, misses the architecture. Poor management implies that better managers could fix it. The evidence says otherwise. Better managers could make better decisions at the margins. They cannot dissolve structural debts, instantly commission refinery capacity, or opt out of the dynamics of currency defence. The weight is not one government's weight. It is the accumulated weight of every government that borrowed without building, every administration that ran a state oil company as a parallel economy, every policy cycle that deferred the hard choices to the next cycle.
What the drains add up to is this: Nigeria earns more when oil prices rise. But the earnings enter a system with prior claims on them. Claims that were established years or decades before the earnings arrived. By the time those claims are satisfied, what remains for reserve accumulation is a fraction of what the headline oil revenue figure suggests.
Grace never sees the oil money. She sees the price of rice, which is the exchange rate translated into a food market, which is the naira, which is what the CBN is defending with the reserves, which are smaller than the headline number shows, because of the invisible IOU and the four drains running simultaneously.
The chain is complete. It runs from the wellhead to her kitchen. It is invisible at every link except the last one, where she measures out a cup and notices it buys less than it did last month.
In Part Four, we ask the question the series has been building toward. If the problem is this structural, if the drains are this persistent, this old, and this deeply embedded in who benefits from the current arrangement, what would it actually take to change it? Not better management. Structural change. What would that require, and who would have to lose something for it to happen?
But underneath that question is a deeper one. A system that is permanently short of reserves cannot plan. It can only react. Governance becomes crisis management. Strategy becomes survival. Institutions stop asking what Nigeria could build over the next decade and start asking what Nigeria can afford this quarter. The psychological consequence of permanent reserve pressure is not just economic. It is the slow replacement of ambition with emergency. And that replacement is the most expensive thing in this entire series. It does not appear in any balance sheet. But Grace feels it every time she reaches for a cup instead of a bag
