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
Hold foreign currency for what you will spend in foreign currency, and keep everyday and emergency money in naira. Beyond that, the share of long-term savings you keep in dollars is a personal choice; many people pick a fixed proportion they can stick to and rebalance once or twice a year, rather than moving everything when the naira falls.
Start with what you spend, not what you fear
After years of naira weakness, many Nigerians feel safer with dollars. That instinct has reasons behind it. But a dollar balance is not automatically a good plan. Your rent, food, transport and school fees are mostly in naira, and converting back and forth costs money each time. The question is not "dollars or naira" but "how much of each, for what".
A three-layer approach
| Layer | Purpose | Currency |
|---|---|---|
| 1. Spending money | The next one to three months of living costs | Naira |
| 2. Known foreign costs | Tuition, visa fees, travel, subscriptions, loan repayments abroad | The currency of the cost |
| 3. Long-term savings | Goals more than a year away | A deliberate mix you choose |
Layer 1: spending money
Keep this in naira. If you hold it in dollars, you will be converting small amounts often, paying a spread each time, and you are exposed if the rate moves against you just before rent is due.
Layer 2: known foreign costs
If you know you will pay £8,000 of tuition next September, building it up in pounds removes currency risk on that bill. The same goes for a dollar subscription, a trip to Dubai or a sibling's visa fee.
Layer 3: long-term savings
This is where the real choice lies. Holding part of your savings in a foreign currency can protect against naira weakness. Holding part in naira lets you use local options that pay interest, such as treasury bills or money market funds, which foreign cash balances may not match. Naira returns need to be judged against naira inflation, and foreign returns against the currency risk you take on.
Picking a share for long-term savings
There is no correct number. A few questions help:
- Will you spend this money abroad? If you plan to study, relocate or retire abroad, a larger foreign share makes sense.
- Is your income in naira or foreign currency? If you earn in dollars, you already have exposure; you may want more of your savings in naira for local goals.
- What return can you get? A foreign balance earning nothing loses value to foreign inflation. A naira investment may earn more but carries currency risk. See real returns in Nigeria.
- How would you feel if the naira strengthened? It can happen. If that would wreck your plans, your foreign share is too large.
Rebalancing: the habit that does the work
Pick a target split, such as 70% naira and 30% foreign for long-term savings, and check it once or twice a year. If the naira falls, your foreign share grows in naira terms; you might convert some back to return to target. If the naira rises, your foreign share shrinks; you might top it up. This forces you to sell a little of what has risen and buy a little of what has fallen, rather than chasing headlines.
Worked example and special cases
Example only; rates and amounts are illustrative. Obinna earns ₦1,200,000 a month and has ₦6,000,000 saved.
- Layer 1: ₦2,400,000 in naira, about two months of costs.
- Layer 2: his daughter's school trip to the UK next year will cost about £1,500. He builds this in pounds, converting a little each month.
- Layer 3: the rest, about ₦3,600,000 less the trip savings. He chooses a 70/30 split: about ₦2,500,000 in naira savings options and the equivalent of about ₦1,100,000 in dollars, roughly $730 at ₦1,500 per dollar.
- Every January and July he checks the split and rebalances if it has drifted more than five points.
If you already earn in foreign currency
Freelancers, remote workers and people paid by family abroad face the opposite problem: most of their money arrives in dollars or pounds, but most of their costs are in naira. For them, the question is how much to convert each month. A simple rule is to convert enough for Layer 1 on a fixed day, keep Layer 2 in its currency, and let the rest build towards the long-term split you have chosen. Our guide for freelancers receiving dollars covers the receiving side.
Mistakes to avoid
- Moving everything into dollars after a sharp naira fall, then needing to convert back at a worse rate to pay bills.
- Keeping foreign cash at home, where it can be lost or stolen.
- Using unlicensed dealers to buy dollars. See buying dollars legally.
- Forgetting that a dollar earning nothing also loses value to US inflation.

Questions people ask
Should I save all my money in dollars in Nigeria?
Usually not. Keep everyday and emergency money in naira, hold foreign currency for foreign costs, and choose a mix for long-term savings that matches your goals.
What percentage of savings should be in dollars?
There is no correct figure. Pick a share based on whether you will spend the money abroad, what your income currency is, and how you would cope if the naira strengthened, then rebalance once or twice a year.
Is it better to save in dollars or naira?
Each has trade-offs. Dollars can protect against naira weakness but may earn little; naira options can earn more but carry currency risk.
Is it safe to keep dollars at home?
It is legal, but risky because of theft, fire and loss. An account with a licensed institution is safer.
