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
You can start dollar savings in Nigeria with as little as $1 in some apps, such as PiggyVest Flex Dollar, or about $10 equivalent in Cowrywise dollar funds. Bank domiciliary accounts we checked ask about $50 to open, the Stanbic IBTC Dollar Fund $100, and the domestic FGN dollar bond $10,000.
The short answer by product
"Dollar savings" covers several different products, and each has its own entry point. These are the minimums printed on providers' own pages, checked in October 2026. Minimums change, so confirm on the page or in the app before you plan around one.

Low minimums: what you get for $1
Apps with $1 minimums let you build a dollar balance a little at a time, often from naira. PiggyVest says Flex Dollar can be funded from Flex Naira or a naira debit card with a $1 minimum, and that the money is invested with SEC-regulated asset managers and Eurobonds.
The catch with small amounts is the conversion. If you fund from naira, the app's rate applies to every top-up, and on a few dollars a flat fee would eat much of the return. Read funding dollar savings from naira before committing to small, frequent deposits.
Bank accounts: $50 to $100 is common
A domiciliary account is a bank account in dollars (or pounds, euros); see domiciliary versus multicurrency accounts. Opening amounts are modest, but some banks set operating balances too: Fidelity's diaspora account lists a $30 minimum operating balance. UBA's Freedom Dom, a basic version, has a balance cap of $2,000 before you upgrade. Most standard domiciliary accounts pay little or no interest; see does a domiciliary account earn interest.
Documents usually include a valid ID, BVN, passport photographs, proof of address and, for current accounts, references. Each bank's list differs, so check before you visit.
Funds and bonds: higher entry, different risk
Dollar mutual funds pool money into Eurobonds and dollar deposits. The Stanbic IBTC Dollar Fund starts at $100 but has a 182-day minimum holding period, with 20% of accrued income charged if you redeem earlier. The domestic FGN dollar bond needs $10,000 and, per the DMO, accepts electronic transfers only, not cash.
Cowrywise's help centre puts its dollar mutual funds at "$10 equivalent", and says you choose from a list of funds in the app, with a short risk assessment to suggest one. Because it is an equivalent, the naira you pay depends on the rate the app applies on the day.
Worked example: building to a fund minimum
Example only. If you can set aside $50 a month, a $1 app balance lets you start now. After two months you have $100, enough for a fund with a $100 minimum. Reaching $1,000 at $50 a month takes 20 months, before any returns.
What to check first
- Whether the minimum is to open, to keep, or per top-up.
- Whether the product accepts naira, dollars, or both, and at what rate.
- Any holding period or early-exit charge.
- Who holds the money: a CBN-licensed bank, or an SEC-registered fund manager (check the ways dollar apps hold your money).
Why the minimum is not the whole story
A low minimum makes it easy to begin, but three other numbers decide whether a product suits a small saver.
Fees that do not shrink with your balance
A fee with a floor hits small deposits hardest. PiggyVest's USD virtual account, for example, charges 0.3% on dollar deposits with a $5 minimum and $25 maximum. On a $100 deposit, 0.3% would be 30 cents, but the $5 floor applies, so the charge is 5% of what you sent. On a $2,000 deposit the same rule costs $6, or 0.3%. Funding from naira avoids that particular fee but brings the conversion rate into play instead.
Holding periods
Funds with low entry points can still tie money up. The Stanbic IBTC Dollar Fund's 182-day minimum holding period means that money you might need within six months is better kept in a plain dollar account. Check whether the penalty falls on your capital or only on the income earned; Stanbic's is 20% of accrued income.
Operating balances and caps
Some bank accounts set a balance you must keep, and some basic accounts cap what you can hold. Fidelity's diaspora domiciliary lists a $30 minimum operating balance; UBA's Freedom Dom tops out at $2,000 before you must upgrade with fuller documents. If you expect your balance to grow, choose an account that will not need changing in six months.
The point of a minimum is to tell you where you can start. The fees, lock-ups and caps tell you where you should.
Where Pryme fits
A Pryme account can be opened from any country and holds USD alongside NGN, GBP and EUR, each with its own account details. It is an account for holding and moving dollars, not an interest-paying savings product. Open an account or see how multicurrency works.
