What the reserves figure doesn't say.

Cardoso opened Tuesday's press briefing with a number he clearly wanted on the record. Nigeria's gross external reserves stood at $55.25 billion as of 18 September, the governor said. That is the highest level in 18 years, enough on paper to cover roughly 11.3 months of imports.

That is a real number, and it means something. Reserves that size give the central bank room to defend the naira when pressure builds. They are one reason the Monetary Policy Committee felt confident enough on Tuesday to cut interest rates by more than anyone expected. That decision was built on the bet that inflation keeps falling from here.

Here is what $55.25 billion does not tell you. It does not tell you what a transfer from London to Lagos actually converts to when it lands. The reserves figure lives in the official market, and the money a diaspora family sends home does not always move through that market cleanly. It does not tell you why the gap between the official exchange rate and what people actually pay on the street has been a persistent, separate story all year. TNL has covered that gap before, and will cover it again. Reserves are a number the central bank controls directly, built from oil receipts, non oil exports and diaspora inflows themselves. What that money is worth by the time it reaches someone's account in Lagos is a number the market controls. The two do not always move at the same pace.

Eighteen years is a real achievement to point to. It is also a number that sits comfortably in a CBN press release without ever having to explain itself to the person checking what their transfer cleared at this morning.
