On 5 November 2026, the naira closed at N1,350.45 per greenback on the Nigerian international alternate market.
That is N4.44 weaker than the N1,346.01 shut on 2 November, in accordance to Central Bank of Nigeria information reported by Nairametrics. Interbank turnover that day was about $82 million, down from about $101 million the session earlier than.
A tender week for the naira is just not uncommon. What is uncommon is that the CBN’s personal journal has simply spelt out a mechanism that matches the tape.
What the examine discovered
A paper within the CBN Journal of Applied Statistics, Budget Deficit Dynamics and Macroeconomic Performance in Nigeria by Ndubuisi E. Uguru, makes use of annual information from 1981 to 2024. ThisDay summarised the findings on 6 November.
Budget deficits are a major driver of exchange-rate depreciation. They account for a big share of short-run foreign money strikes and preserve pushing the foreign money weaker over time. They additionally put delayed upward strain on rates of interest. Money provide can shrink when the central financial institution tightens to include the fallout from authorities borrowing.
The examine finds no statistically important direct hyperlink between deficits and inflation. In that framework, Nigeria’s inflation tracks provide shocks, structural bottlenecks, and the pass-through from a weaker naira into native costs. The fiscal problem reveals up first within the alternate charge and the price of cash, then in costs by way of the foreign money.
That sample has a reputation: fiscal dominance. Government financing wants constrain how freely the central financial institution can chase financial stability by itself.
Why this week issues
Gross exterior reserves rose by solely $295.35 million in October 2026, Nairametrics stories. That was the slowest optimistic month-to-month improve to date this yr. Net international alternate reserves have reached a file $46 billion, up from $34.80 billion on the finish of 2025. The buffer is bigger. The naira nonetheless slipped within the first week of November.
Reserves assist. They don’t cancel a persistent deficit that competes for {dollars} and home credit score. When the federal government borrows closely at residence, non-public debtors face greater charges.
When the deficit feeds depreciation fears, importers and portfolio managers bid for {dollars}. Both channels present up in the identical week: a weaker official charge and a tougher path to decrease the Monetary Policy Rate.
The MPR is 23 per cent after the 350-basis-point minimize on 22 September. Headline inflation was 14.63 per cent in September. The hole seems to be like room to ease. Fiscal strain is why that room can shut once more.
What ought to change
First, go a legally binding fiscal rule that caps the price range deficit as a share of GDP. The CBN paper asks for this. A tender goal that may be rewritten every price range cycle is just not a rule.
Second, coordinate fiscal and financial operations publicly. Abrupt liquidity squeezes after giant authorities disbursements are a expensive approach to study that the 2 sides of the state aren’t speaking. A printed framework would let the CBN handle liquidity earlier, not solely after the injury.
Finally, cease treating a bigger reserve inventory as proof that the alternate charge is settled. Watch the deficit path and the home borrowing calendar. Those are the variables the CBN examine hyperlinks to depreciation and better charges.
The working conclusion
Nigeria can maintain extra {dollars} and nonetheless see a softer naira if the deficit retains setting the tempo. The CBN research is the financial institution’s personal journal saying that fiscal imbalances drive the foreign money, elevate charges with a lag, and drive defensive tightening.
Fix the deficit rule and the naira debate will get smaller.
