Nigeria's cheaper money went straight back to the central bank

The banks took the cheaper money, looked at the economy, and deposited it right back where it came from.

The comedy is in the plumbing. A central bank cuts the price of money by three and a half percentage points — the boldest easing of the Tinubu era, delivered by the 307th Monetary Policy Committee on September 22 — and the banking system responds by handing the money straight back. In the week to September 25, banks parked more than ₦7 trillion at the CBN's own overnight window: the easing went out the front door and came back through the vault. It is the monetary-policy equivalent of pouring water into a bucket with no bottom and declaring the floor wet.

To see why, follow the incentives. The MPR — the monetary policy rate, the price the central bank charges — fell to 23%. But no business borrows at the policy rate; by the time the banks add their margins, their risk premiums and their operating costs, the real price of a loan sits above 30%. Lending at 30% into an economy growing modestly, where power costs punish every factory and FX risk never sleeps, is an act of faith the banks are not paid to perform. Parking cash at the central bank — even inside a narrowed corridor, even at a rate below the headline — is the risk-adjusted winner. The trade is not mysterious. It is arithmetic, and the arithmetic says: don't lend.

The numbers are almost comic. On September 22, the Central Bank of Nigeria's 307th Monetary Policy Committee cut the MPR by 350 basis points to 23% — the boldest easing of the Tinubu era, meant to coax credit into a starved real economy. In the week to September 25, banks parked more than ₦7 trillion at the CBN's own overnight window. The easing went out the front door and came back through the vault.

The banks' behavior is rational, which is what makes it damning. Lending to Nigerian businesses at 23% policy rates means lending at 30%+ in practice, into an economy growing modestly, with power costs punishing and FX risk never far. Parking cash at the central bank — even inside a narrowed corridor — is the risk-adjusted winner. The CBN cut the price of money; it could not cut the price of risk.

This is how monetary transmission is supposed to work, and why its failure matters. The textbook chain runs: central bank cuts the policy rate, funding gets cheaper for banks, banks pass the cheaper funding to borrowers, borrowers invest and hire, the economy grows. Every link in that chain is a decision, and in Nigeria every decision after the first one said no. The CBN cut the price of money; it could not cut the price of risk. That sentence — the article's thesis — is worth sitting with, because it describes the limit of what any central bank can do. Interest rates are a price. Risk is a judgment. No committee votes on judgment.

The numbers behind the judgment are stark. Private-sector credit stood at ₦84.55 trillion in August — a large number that shrinks on contact with 15.39% inflation. In an economy where prices rise fifteen percent a year, flat nominal credit is a contraction in real terms: the banking system's exposure to the private sector is falling while the headlines celebrate easing. The banks are, in real terms, disinvesting from Nigerian enterprise — lending less, in purchasing-power terms, than the year before. The ₦7 trillion at the overnight window is the liquid form of that verdict. It is not laziness. It is a forecast.

The external accounts tell the opposite story, and the contrast is the administration's genuine achievement. The naira holds at ₦1,328.67 to the dollar. Reserves sit at $54.83 billion — an eighteen-year high. Oil flows steadier, the FX backlog that once strangled importers has been cleared, and the parallel-market premium — the gap between the official rate and the street rate that measured the old regime's dishonesty — has been compressed. These are the fruits of the Tinubu-era reforms: the exchange-rate unification, the clearing of the dollar queue, the slow repair of credibility with the markets. No one can call it failure. It is, by the standards of Nigeria's recent history, a fortress.

But a fortress with empty barracks is the article's image, and it is exact. The defenses are impressive — reserves at a generational high, the currency stable, the backlog gone — and nobody is manning the economy: credit to the private sector shrinking in real terms, banks preferring the central bank's window to the country's businesses. External stability without domestic credit is a peculiar kind of strength. It impresses the carry traders and the rating agencies. It does not build a factory, fund a harvest, or finance the power plant that would make the next loan bankable. The fortress keeps the currency safe. The economy inside it is on its own.

The CBN cut the price of money; it could not cut the price of risk.

The 307th meeting matters as a number because it measures the institution's age and, by implication, its habits. Three hundred and seven times the committee has gathered, voted, and communicated — and the market has learned to read not just the decision but the theater around it. The September cut was staged as boldness: 350 basis points, the biggest easing of the Tinubu era, a signal that the hiking cycle that tamed inflation was over and the growth cycle could begin. The banks' response — ₦7 trillion back at the window within days — was the market's review of the performance. Boldness, it turns out, is not measured in basis points. It is measured in loans.

There is a history behind the banks' caution, and it is written in non-performing loans. Nigerian banks have lived through cycles where directed lending, political credit, and oil-price collapses left their balance sheets scarred — and scarred lenders do not relearn courage because a committee voted. The risk officers pricing a 30% loan against a manufacturer with punishing power costs are not being timid; they are remembering. Institutional memory is the transmission mechanism's hidden gear: the CBN can change the price of money overnight, but it cannot change what the banks learned over a decade. The ₦7 trillion is tuition already paid, and the banks are not enrolling again.

Private credit tells the same story in slower motion: ₦84.55 trillion in August, shrinking in real terms against 15.39% inflation. In an economy where prices rise fifteen percent a year, flat nominal credit is a contraction — the banking system is, in real terms, disinvesting from the private sector while the headlines celebrate easing.

The naira, meanwhile, holds at ₦1,328.67, and reserves at $54.83 billion are an eighteen-year high. The external accounts are the administration's genuine achievement — oil flows steadier, the FX backlog cleared, the parallel-market premium compressed. But a strong reserve position funding a weak credit system is a fortress with empty barracks: the defenses are impressive, and nobody is manning the economy.

The MPC's next move is now the market's guessing game. Cut again and watch the deposits pile higher — proof of impotence. Hold, and admit the September cut was premature.

The MPC's next move is now the market's guessing game, and both options are traps. Cut again, and watch the deposits pile higher — proof, in real time, that the easing is not transmitting, that each new cut is just a larger subsidy to the banks' arbitrage. Hold, and admit the September cut was premature — that the boldest easing of the era was a gesture the economy could not use. Central banks hate both admissions: impotence and error are the two words no communiqué can contain. The likeliest path is the one committees always take when the data contradicts the decision — wait, watch the window, and hope the ₦7 trillion starts moving on its own.

It will not move on its own, because the price of risk is set outside the CBN's walls. Power costs, FX volatility, the regulatory weather, the simple fact that lending to a Nigerian SME at 30% requires a belief in the borrower's future that the numbers do not support — none of these yield to a policy rate. What would move the deposits is not cheaper money but safer lending: reliable electricity that makes factories viable, courts that enforce contracts, a growth model where enterprise risk is priced as opportunity rather than hazard. Those are fiscal and structural reforms, not monetary ones. The MPC can cut to zero and the banks will still prefer the window, because the window is the only borrower that always repays.

The Western investor lens is the carry arithmetic. At 23% policy rates with a stable naira and $54.83 billion in reserves, Nigeria screens as the EM carry trade's next address — the very trade unwinding in Mexico tonight is hunting for a new home. The Western read: the ₦7 trillion at the window is dry powder, and foreign funds are deciding whether to join it.

The IMF-style Western technocratic lens is sterner: monetary transmission this broken means the policy rate is decorative. Easing that ends as central-bank deposits is fiscal dominance wearing a monetary mask — and the Fund's next Article IV will say so, politely.

The Western carry-trade lens is the market's most cynical and most honest reading. At 23% policy rates with a stable naira and $54.83 billion in reserves, Nigeria screens as the emerging-market carry trade's next address: borrow where money is cheap, park it where money pays 23%, pocket the difference as long as the currency holds. The very trade unwinding in Mexico tonight is hunting for a new home, and the ₦7 trillion at the window is, in this telling, dry powder — domestic liquidity demonstrating the trade's logic, foreign funds deciding whether to join it. The carry trade does not need the real economy. It needs the currency to stay still and the rate to stay high. Nigeria currently offers both.

The IMF-style technocratic lens is sterner, and it is the one that will matter in Washington. Monetary transmission this broken means the policy rate is decorative — a number the committee votes on while the economy prices something else. Easing that ends as central-bank deposits is fiscal dominance wearing a monetary mask: the state, in effect, paying banks to hold its liabilities rather than fund its economy. The Fund's next Article IV consultation will say so politely, in the coded language of surveillance reports — 'impaired transmission,' 'limited pass-through' — but the meaning will be plain. A central bank whose cuts do not cut is a central bank performing policy rather than conducting it.

Beijing's lens is the creditor's patience. China holds Nigerian infrastructure debt and watches the credit data as a repayment indicator: an economy where banks will not lend is an economy where projects stall. The Eastern read is practical — the naira's stability and the reserves high matter more than the MPC's theater, because they underwrite the debt service.

The Gulf's Eastern-adjacent lens is the FX one. With reserves at an 18-year high and the naira at 1,328, Nigeria's external position is the strongest in a generation — the kind of stability that invites Gulf sovereign capital into infrastructure and energy. The rate cut's failure is domestic; the external story still sells.

Beijing's creditor lens is the most patient and the most practical. China holds Nigerian infrastructure debt — the railways, the ports, the power projects — and watches the credit data as a repayment indicator, because an economy where banks will not lend is an economy where projects stall and revenues sag. The Eastern read discounts the MPC's theater entirely: the naira's stability and the reserves high matter more than any rate decision, because they underwrite the debt service. A borrower that holds $54.83 billion in reserves and a steady currency will pay. The rate cut's failure is domestic; the external story still sells. Creditors grade the fortress, not the barracks.

The Gulf's adjacent lens is the FX one, and it is increasingly the lens that counts. With reserves at an eighteen-year high and the naira at 1,328, Nigeria's external position is the strongest in a generation — the kind of stability that invites Gulf sovereign capital into infrastructure and energy. Sovereign wealth does not need the transmission mechanism to work; it needs the currency to hold and the state to honor its contracts. The rate cut's domestic failure is, from Abu Dhabi or Riyadh, a footnote to the main story: Nigeria can pay, Nigeria is stable, Nigeria is open for the kind of capital that builds ports. The barracks may be empty. The fortress is accepting investors.

Africa's lens is recognition with an edge. Every African finance ministry has watched banks arbitrage the central bank instead of lending to the economy — it is the continent's oldest monetary pathology. The Southern read: Nigeria just demonstrated, at continental scale, that the policy rate is a suggestion and risk appetite is the policy.

The harder Southern reading is about the real economy's verdict. When banks prefer 23%-minus-a-corridor at the central bank to 30%+ from businesses, they are pricing Nigerian enterprise risk as uninvestable. That is not a liquidity problem. It is a growth-model problem, and no MPC vote fixes it.

Africa's lens is recognition with an edge, because the continent has seen this film. Every African finance ministry has watched banks arbitrage the central bank instead of lending to the economy — it is the continent's oldest monetary pathology, the polite form of financial repression in reverse. The Southern read is unsentimental: Nigeria just demonstrated, at continental scale, that the policy rate is a suggestion and risk appetite is the policy. The committee votes; the risk officers decide. Every central bank on the continent will clip this story, because every one of them lives some version of it.

The harder Southern reading is about the real economy's verdict, and it is the one that should keep policymakers awake. When banks prefer 23%-minus-a-corridor at the central bank to 30%+ from businesses, they are pricing Nigerian enterprise risk as uninvestable — not illiquid, not cyclical, but structurally unworthy of capital. That is not a liquidity problem. It is a growth-model problem: power too costly, contracts too uncertain, returns too thin for the risk. No MPC vote fixes a growth model. The ₦7 trillion sitting at the overnight window is not just liquidity. It is a vote of no confidence, cast by the very institutions the cut was meant to mobilize — and no-confidence votes, once cast, are not withdrawn by communiqués.

So the September cut will be remembered as the easing that proved easing was not the problem. The price of money fell; the price of risk did not; the banks did the arithmetic and chose the vault. The next MPC meeting will face the same arithmetic, and the one after that, until the structural work — power, courts, the cost of doing business — makes lending the rational choice again. The CBN cut the price of money by three and a half percentage points. The economy's reply, in ₦7 trillion of parked cash, was precise: cut the price of risk, and we will talk. Until then, the window stays open, and the money stays home.
