If you sent money home in late August and again this week, the naira you bought may already have been worth less to your family. Not because it weakened, but because it strengthened.

This isn't a one-day move either. On the official interbank rate, confirmed independently by both Investing.com's GBP/NGN series and the CBN's own published figures, the pound bought ₦1,812 on 31 August and ₦1,794 by 11 September, a decline of just under 1% over eleven days. That's the reference rate, not what shows up on a remittance app; bureau-de-change rates in Lagos and Abuja have been running roughly ₦80–110 higher than this over the same period.

The CBN still has a significant hand in the conditions under which the naira trades. That's through monetary policy, FX-market rules and the management of liquidity. But the exact reason for this month's movement needs to be separated from the movement itself. What's established is that the rate moved, not why, and that distinction matters more than it sounds.

Here's what it means for you. A stronger naira can help Nigeria's inflation fight by making imports cheaper in naira terms. For anyone sending pounds home, though, the effect is immediate and more personal.

The same £500 you sent in August may buy fewer naira in September. Not necessarily because your bank changed its fees, but because the exchange rate used to convert your pounds has changed.

At ₦1,900 to the pound, £500 becomes ₦950,000. At ₦1,800, it becomes ₦900,000. The difference is ₦50,000, before any fees or provider margins.

The question worth sitting with isn't what to do about it. It's whether you're checking the rate you're actually getting on each transfer, or assuming it's roughly what it was last time you sent money.
