Nigeria's FX taps reopen: CBN dollar sales jump to $953m in March

For anyone tracking the pulse of Africa's largest economy, the quiet numbers buried in Nigeria's central bank data are sometimes louder than any headline. In March, the Central Bank of Nigeria (CBN) reported total foreign exchange sales of $953.41 million — the highest monthly figure since April 2025. That number alone is striking, but the trajectory is the real story: after a dismal January that saw just $58.93 million in sales and a February that crept to $244.13 million, March's rebound represents a 291% jump month-on-month and more than sixteen times the January figure. The tap, it seems, has been turned back on.

To understand why this matters, you have to grasp the peculiar mechanics of Nigeria's dollar economy. For decades, the CBN was the gatekeeper of foreign currency, rationing dollars through a maze of windows — from the Wholesale Dutch Auction System to the Investor and Exporter window — each with its own rate, each ripe for arbitrage. That system collapsed into a unified exchange rate in 2023, a painful but necessary reform that killed the parallel-market premium and forced a reckoning. The March data shows how far the landscape has shifted: sales to ministries and agencies accounted for just $3.31 million, while the once-dominant channels — WDAS, interbank, BDC, SME — recorded zero. The central bank is no longer the main act; it's a supporting player.

The real muscle now sits outside the CBN's direct control. Autonomous sources — private capital flows from diaspora remittances, portfolio investors, and exporters — accounted for 64.94% of total FX inflows in 2025, according to earlier reporting. Those inflows surged to $72.91 billion last year, up from $59.29 billion in 2024 and $41.80 billion in 2023, nearly doubling in just two years. That's the quiet revolution: Nigeria's foreign exchange market is being weaned off central bank intervention and onto the discipline of private flows. The March sales spike, then, is less about the CBN flooding the market and more about a recalibrated system finding its footing after a January slump that likely reflected seasonal lulls and policy hesitation.

For the international reader, this is a bellwether for how Africa's biggest economy manages scarcity. When the CBN sells more dollars, it signals confidence — or at least a willingness to smooth volatility rather than hoard reserves. The naira's stability, which has held around N1,837 to the pound recently, depends on this delicate dance. The March figure suggests the central bank is comfortable deploying its arsenal after a cautious start to the year. But the composition of that supply — almost entirely through reported sales channels, with the traditional windows silent — tells you the old playbook is dead.

What does this mean for wealth watchers? First, it's a reminder that Nigeria's FX market is no longer a one-way street dominated by the state. Private capital is the new engine, and that's a structural shift that rewards businesses with genuine dollar earnings and punishes those who relied on arbitrage. Second, the March rebound could be a precursor to more aggressive CBN activity if the naira faces pressure from global currency movements — the pound's strength and dollar dynamics are never far from Lagos trading desks. The central bank's decision to open OMO securities to individuals and expand banks' access to the Nigerian Foreign Exchange Market signals a broader push for liquidity and participation.

Looking ahead, the question is whether March was a blip or a baseline. Nigeria's FX inflows have been climbing steadily, but the first two months of 2026 showed how fragile that momentum can be. If autonomous flows keep rising — and the data suggests they are — the CBN's role will keep shrinking, which is ultimately a sign of health. For now, the $953 million figure is a vote of confidence in a market that has spent three years learning to stand on its own. The next quarterly bulletin will tell us if that confidence holds, or if March was just a good month in a long, uneven climb.
