AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
Keep in naira only what you expect to spend in naira: family support, school fees, building costs, trips home. Money held in naira faces two risks at once, Nigerian inflation (headline 14.63% in September 2026, per the NBS) and changes in the naira's value against the pound, so savings meant for a UK future are usually safer in pounds. Naira interest can offset some of that, but only if it beats both.
If you live in the UK but still have money in Nigeria, you are effectively holding a second currency. That can be sensible or costly depending on what the money is for. The question is not whether naira is good or bad; it is whether the currency you hold matches the currency you will spend. This article walks through the two risks in plain terms, with a worked example, and ends with a simple way to decide how much to keep.
Risk one: inflation in Nigeria
Inflation is the rate at which prices rise. The National Bureau of Statistics put headline inflation at 14.63% year on year in September 2026, down from 15.39% in August and from 20.98% a year earlier, with food inflation at 19.59%. The CBN has said it is moving toward inflation targeting with a medium-term goal of 6-9%, without a deadline. If your naira earns less than inflation, it buys less each year in Nigeria.
For money you will spend in Nigeria, this is the risk that matters most. If you are saving for a building project in Enugu or school fees in Abuja, the relevant question is whether your naira grows faster than prices there. The Nigeria-side detail on real returns is in is your savings beating inflation?.
Risk two: the naira against the pound
If you will eventually spend the money in the UK, there is a second risk. Your naira may hold its value in Nigeria and still buy fewer pounds later, if the naira weakens against sterling. The reverse can happen too. Exchange rates move in both directions, and nobody can tell you the next move. That uncertainty is the core reason UK-based savers are cautious about holding long-term savings in naira.
There is also a cost to switching. When you convert, you pay a margin between the rate you get and the mid-market rate, plus any fee. In mid-October 2026, Techeconomy reported a gap of roughly 3% between the official market rate for dollars and the street rate, a reminder that the rate you are quoted depends on where you convert. See why converting naira to pounds loses money.
A worked example
Example only, with simple numbers. Suppose you hold ₦2,000,000 in a Nigerian savings product paying 18% a year, and inflation stays near September 2026's 14.63%.
| Step | Calculation | Result |
|---|---|---|
| Balance after one year | ₦2,000,000 x 1.18 | ₦2,360,000 |
| Real growth in Nigeria | 1.18 / 1.1463 - 1 | about 2.9% |
| If the naira weakens 10% against the pound | ₦2,360,000 buys 10% fewer pounds than at the start rate | value in pounds about 6.2% higher than the start, not 18% |
| If the naira weakens 20% | 1.18 x 0.80 - 1 | value in pounds about 5.6% lower than the start |
The 10% row: 1.18 x 0.90 = 1.062, so a 6.2% gain in pound terms. The lesson is that a high naira interest rate is not the same as a high return for someone who will spend in pounds. It depends on the exchange rate, which you cannot fix in advance.
How much to keep in naira
A practical approach is to label money by where it will be spent:
- Spending in Nigeria within a year (family upkeep, fees, Christmas trip): keeping it in naira avoids converting twice.
- Committed naira costs further out (a building, a land payment): naira savings that beat inflation can make sense, accepting the currency risk only matches the cost.
- UK goals (a deposit, emergency fund, retirement): keep these in pounds.
- Undecided: hold the default in the currency you live in, which for most readers is pounds.
Two further checks. First, deposit insurance: NDIC cover is naira-for-naira per depositor, with a maximum of ₦5,000,000 at deposit money banks and ₦2,000,000 at microfinance banks, per its FAQ. Second, if you hold dollars as a middle ground, the Nigeria-side rules are in how much to keep in dollars. For UK-based investors weighing naira assets more broadly, see FX risk on naira investments.
Interest rates are moving
The CBN cut its Monetary Policy Rate from 26.5% to 23% on 22 September 2026. Savings and Treasury bill rates tend to follow policy rates over time, so naira returns quoted last year may not be on offer now. Check the current rate on the product before you assume it beats inflation.
Where Pryme fits
Matching currency to spending is easier when both sit in one account. A Pryme Personal Account can be opened from the UK and holds naira and pounds side by side; money stays in the currency it arrived in, and Swap converts only when you choose, showing the rate and the fee before you approve. For naira you plan to keep for a while, Savings Boxes (naira only) let you set money aside, with rates shown in the app. Naira deposits are held by a licensed Nigerian microfinance bank, regulated by the CBN and insured by the NDIC up to the applicable limit.
Questions people ask
Is it a good idea to keep savings in naira if I live in the UK?
For money you will spend in Nigeria, often yes. For money you will spend in the UK, naira adds exchange rate risk on top of Nigerian inflation, so pounds are usually the safer default.
What is Nigeria's inflation rate now?
The NBS put headline inflation at 14.63% year on year in September 2026, released on 15 October 2026. Check the NBS for the latest month.
Does naira interest make up for the exchange rate?
Only sometimes. In the worked example, 18% naira interest becomes about 6.2% in pound terms if the naira weakens 10%, and a loss if it weakens 20%.
Is my naira insured?
NDIC insures deposits at licensed banks up to ₦5,000,000 per depositor at deposit money banks and ₦2,000,000 at microfinance banks, according to its FAQ.
