The CBN Cut Rates to 23%. What Is It Actually Betting?

On 16 September the US Federal Reserve raised its benchmark interest rate for the first time since 2023, to a range of 3.75% to 4%. The vote was unanimous. Sixteen of eighteen policymakers signalled another increase before the year ended, and minutes released in early October confirmed that all nineteen participants had backed the move.

Six days later, on 22 September, at the conclusion of its 307th meeting, Nigeria's Monetary Policy Committee reset the Monetary Policy Rate from 26.50% to 23%.

That is a cut of 350 basis points — three and a half percentage points — taken in the same week that the world's most important central bank went the other way. It is the largest single move in Nigeria's policy rate in years, and it deserves more scrutiny than it has received.

What makes it genuinely interesting is not the size. It is the label.

The word the MPC chose

The Committee did not present this as monetary easing. It described the change as an operational reset, intended to improve what economists call transmission, and said it was not a shift in stance.

That phrase needs unpacking, because it is the key to the whole decision.

Transmission is the process by which a central bank's announced rate actually reaches you. The CBN sets a number. That number is supposed to influence what banks charge each other overnight, which influences what they charge businesses, which influences what you pay on a loan and earn on a deposit.

In Nigeria, that chain has been loose for a long time. The policy rate said 26.50%, while actual market rates — what banks genuinely lent to each other at — were sitting well below it. The official number had drifted away from reality. A central bank in that position is holding up a sign that nobody in the market is reading.

So the MPC's argument is that it did not loosen policy. It moved the official number down to where market rates already were, so that the sign and the street finally agree. Alongside that, it recalibrated the standing facilities corridor to plus 50 and minus 300 basis points around the new rate, and adopted the Nigerian Overnight Financing Rate — a benchmark built from actual transactions rather than from a committee's judgement — as the reference point.

Cash reserve requirements were left untouched: 45% for commercial banks, 16% for merchant banks, 75% for non-TSA public sector deposits. That matters, and I will come back to it.

Is the framing honest?

Partly. And the part where it is not is the part worth watching.

The transmission argument is real. Anyone who has looked at the gap between Nigeria's policy rate and its interbank rates over the last two years knows the official number had become somewhat ceremonial. Fixing that is good central banking, and a committee that says so plainly is being more candid than most.

But here is the thing a borrower should understand. Whatever the intention, the announced price of money in Nigeria is now 23% rather than 26.50%. Banks price loans off it. Treasury auctions take their cue from it. Foreign investors comparing Nigerian yields against American ones look at it. You cannot move the headline number down by three and a half points and have the world treat it as an administrative footnote.

Calling it an operational reset is a way of saying: do not read this as the start of an easing cycle, do not price in three more cuts, and do not assume we have stopped caring about inflation. That is a reasonable message to send. It is also, in effect, a request that markets ignore the mechanical consequences of the thing the Committee just did.

What the numbers gave them cover to do

To be fair to the MPC, the data in front of it was the best in years.

Inflation eased to 15.39% in August from 15.43% in July — a third straight month of cooling, though food inflation remained at 19.57% while core inflation sat at 13.29%. Gross external reserves reached $55.25 billion by 18 September, the highest in eighteen years and enough for roughly 11.3 months of imports. The economy grew 4.43% in the second quarter, up from 3.89% in the first, with oil output expanding 7.31% and non-oil 4.31%. The balance of payments showed a $3.51 billion surplus for the quarter and the current account a $7.54 billion surplus. The purchasing managers' index rose to 52.7 in August from 51.1, meaning businesses reported expansion rather than contraction.

That is a coherent picture of an economy stabilising. If you were ever going to move, this was the quarter.

The risk the Committee is carrying

Two weeks ago in this section I argued that the Fed's September hike had made a Nigerian rate cut expensive, and that the CBN's dilemma was real. The Committee cut anyway. So let me be straight about what that means rather than pretend I called it.

The risk has not disappeared; it has been accepted.

Foreign portfolio money came into Nigeria for a simple reason: the yield was excellent and the currency was being held steady. Every basis point off the Nigerian side and every basis point onto the American side narrows that attraction. Meanwhile the dollar has been trading near an eighteen-month high and US Treasury yields near their highest levels in more than two decades. The gap is closing from both ends at once.

The Committee's cushion is the reserve position, and $55.25 billion is a genuine cushion. But as I wrote here last month, a reserve pile that includes a large share of rented money is a conditional buffer, not a savings account. The cut is a bet that the reserves will hold the currency steady long enough for the economy to grow into the lower rate. That bet may well pay off. It is still a bet, and the MPC itself listed the things that could break it: Middle East tensions, global commodity prices, trade fragmentation and election-related spending.

Why your loan probably has not got cheaper

Here is the part that will frustrate readers, and it is where the unchanged cash reserve ratio matters.

A 45% cash reserve requirement means that for every ₦100 a bank takes in as deposits, ₦45 must sit with the central bank earning nothing. The bank has roughly ₦55 to work with, and it must cover its costs and make a profit from that smaller base. That pushes up the rate it needs to charge on every loan it does make, regardless of what the policy rate says.

So the MPC lowered the signal and left the constraint. If you are waiting for your overdraft to reprice, that is why it is taking longer than the headline suggested.

The other reason is competition for the government's business. With bond auctions still clearing at attractive levels, a bank can earn a comfortable return without taking credit risk on a manufacturer. Lower policy rates do not change that calculation much. Only a narrower gap between what the government pays and what a business can bear will.

What to do with this

If you have naira savings in fixed deposits or treasury bills, expect the returns on new placements to come down. If you were planning to roll over at the old rate, do the arithmetic again, and compare the new rate to inflation rather than to zero.

If you are borrowing, ask your bank directly whether your facility reprices with the MPR and on what schedule. Many Nigerian loans are priced off a bank's own base rate plus a margin, which does not move automatically. The answer is in your offer letter.

If you hold dollars or expect dollar costs, nothing about this decision makes the naira safer. It makes the carry trade less rewarding, which is the opposite.

And if you are reading the next few months of coverage, watch the gap between the official exchange rate and the parallel market. That gap, not the policy rate, is where you will find out whether the Committee's bet is working.

The CBN made the boldest monetary decision of the year and described it as housekeeping. The honest version is that it saw a stabilising economy, a record reserve buffer and a loan market crying out for cheaper credit, and decided the risk of acting was smaller than the risk of waiting.

That is a defensible judgement. It is just not a technical one.
