The Price of Easing: How Nigeria’s 350bps Cut Cost It The Carry-Trade Crown
The decision of the Central Bank of Nigeria to cut its Monetary Policy Rate by 350 basis points to 23% at its 307th meeting was presented as an operational reset to improve monetary transmission. But in the brutal arithmetic of global capital, it has done something else: it has surrendered Nigeria’s most potent weapon for attracting hot money.
For the last year, Nigeria sold itself to foreign portfolio investors on one simple promise – bring your dollars, earn a real return you cannot get anywhere else. With inflation at 15.39% and MPR at 26.5%, the real return was above 11%. That was carry-trade heaven. The September 22 cut has compressed that to 7.61%. Still high by global standards, where the US offers less than 0.5% and Europe offers negative real returns, but no longer the highest in West Africa.
This is where Ghana enters the story and reframes the whole debate. Ghana’s policy rate is only 14%, nine full points below Nigeria’s. On nominal terms, Nigeria looks tighter and more serious. But inflation in Ghana is now 5%. That leaves a real return of 9 percentage points, wider than Nigeria’s 7.61%. For a fund manager in London deciding where to park $50 million for 90 days, the calculation is not about who shouts the highest rate, but who gives the biggest cushion after inflation erodes the return. Today, that is Ghana.
The implication is critical because carry-trade is not neutral capital. It is the fastest moving, most sentiment-driven dollar Nigeria gets. It is what built the reserves back to $55 billion. When the real rate gap narrows, that dollar looks elsewhere. The CBN is betting that consistency, FX reforms and the closure of the multiple-rate window that once cost 2.2% of GDP will keep investors, even with lower rates. That bet is not yet proven. As Bismarck Rewane of Financial Derivatives noted, the naira stayed flat around N1,387 after the cut, suggesting no immediate exodus, but also no celebration.
There is a deeper trade-off the rate cut exposes. Nigeria has cut its MPR by 4.25 percentage points since September 2024, from 27.25% to 23%, while inflation fell about 9 points. From a price stability perspective, Rewane argues, it is working. But cutting rates while inflation risks are rising again – with petrol, cooking gas and jet fuel prices expected to push headline inflation to 16% in October – could compress the real return to around 7% or even lower. If Ghana holds inflation at 5%, the gap between the two countries widens further in Ghana’s favour.
The other implication is domestic. Carry-trade advantage is good for reserves, but bad for savings and production if rates stay punitively high. High MPR means banks price loans at 30% plus, strangling manufacturers who should be exporting. By cutting, the CBN is trying to rebalance toward growth, as seen in its simultaneous recalibration of the corridor to +50/-300 basis points to make the MPR a truer signal. The danger, as Rewane warned, is that if savings returns fall too fast, Nigerians will dollarize, buy Bitcoin and other assets, creating the very pressure on the naira that higher reserves were meant to prevent.
In essence, Nigeria is at a classic emerging market crossroads. It can no longer win the trade advantage game by simply having the highest interest rate. Its advantage must now come from actually lowering inflation faster than Ghana, Kenya and South Africa. If it fails, the 350bps cut will be remembered not as an easing, but as the moment Nigeria handed its carry-trade edge to Accra.
