In 2022 a Nigerian saver needed about 426 naira to buy one dollar at the official rate. In 2025 the same dollar cost about 1,518 naira, according to World Bank annual averages. Put 426,000 naira under the mattress and it went from roughly 1,000 dollars to roughly 281 dollars in three years, before any interest a local deposit might have paid. That sum explains stablecoins as dollar access better than any white paper: for people in weak-currency countries, a token worth one dollar on a phone can be the nearest thing to a dollar account they can open.
This lesson follows our overview of what DeFi does and does not do in Africa. It looks at what such a token really is, how the law differs in Nigeria, Ghana, Kenya, Egypt and the CFA franc zone, what interest a holder can earn, and what can go wrong. Figures are dated, law is stated as of 2 November 2026, and nothing here is investment or legal advice.
Stablecoins as dollar access: why a phone beats a bank queue
The need comes first. Chainalysis, in its 2026 report on sub-Saharan Africa, published on 29 October 2026, describes a region where local currencies swing, access to foreign currency can be restricted and cross-border transfers are slow and costly. In that setting, it says, stablecoins let people hold dollar value without opening a dollar bank account.
A reminder of the object itself, since it is covered in our lesson on what stablecoins are: a private company issues a token and promises to redeem it for one dollar, holding reserves to back that promise. Two names dominate. As of 2 November 2026, DefiLlama counts about 298.7 billion dollars of stablecoins, of which USDT is 179.2 billion and USDC 71.4 billion. More than half of all USDT, 92.3 billion, sits on Tron. The differences between the two are set out in our USDT and USDC comparison, which is the page to read before choosing one.
What the numbers say: five years of inflation and devaluation
Consumer price inflation shows how fast local money lost buying power at home. The World Bank series below stops at 2025, the latest full year available.
| Annual inflation, % | 2021 | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|---|
| Nigeria | 17.0 | 18.8 | 24.7 | 33.2 | 23.0 |
| Ghana | 10.0 | 31.3 | 38.1 | 22.8 | 14.2 |
| Egypt | 5.2 | 13.9 | 33.9 | 28.3 | 14.1 |
| Kenya | 6.1 | 7.7 | 7.7 | 4.5 | 4.1 |
| Cameroon | 2.3 | 6.2 | 7.4 | 4.5 | 3.4 |
| Senegal | 2.2 | 9.7 | 5.9 | 0.8 | 1.5 |
| Côte d’Ivoire | 4.2 | 5.2 | 4.4 | 3.5 | 0.1 |

The exchange rate shows the other half: what the local currency buys abroad.
| Local currency per US dollar, yearly average | 2021 | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|---|
| Nigerian naira | 401.2 | 426.0 | 645.2 | 1,479.0 | 1,518.4 |
| Ghanaian cedi | 5.8 | 8.3 | 11.0 | 14.2 | 12.6 |
| Egyptian pound | 15.6 | 19.2 | 30.6 | 45.3 | 49.2 |
| Kenyan shilling | 109.6 | 117.9 | 139.8 | 134.8 | 129.3 |
| CFA franc (XAF, XOF) | 554.5 | 623.8 | 606.6 | 606.3 | 581.9 |
Source: World Bank, official exchange rate, period average, retrieved 2 November 2026.
On those averages, our arithmetic gives a loss of dollar value between 2021 and 2025 of about 74% for the naira, 68% for the Egyptian pound, 54% for the cedi, 15% for the shilling and 5% for the CFA franc. Those are five different stories, and the last two hardly fit the usual pitch.
The table also shows that the dollar can fall. The cedi recovered from 14.2 to 12.6 per dollar on average between 2024 and 2025, and the shilling from 139.8 to 129.3 between 2023 and 2025. Someone who changed into dollars at the worst moment saw those dollars buy less at home afterwards.
How much of this is real use
That report puts sub-Saharan Africa’s crypto economy at 101 billion dollars from 1 July 2025 to 30 June 2026, up 13.4% on the year, with South Africa at 39.3 billion and Nigeria at 38.1 billion, down 3%. The firm says stablecoin value received peer to peer in the region has grown more than sixfold since 2022, and that stablecoin remittances rose from 235 million to 492 million dollars in a year. In Nigeria, cross-border peer-to-peer flows fell 17% and blockchain, where users swap tokens directly from their own wallets without handing custody of their funds to a company.">decentralised exchange activity fell 45%, while domestic exchanges took 6.22 billion dollars, about half of inflows to centralised exchanges.
One finding spoils the tidy story. Bitcoin, not a stablecoin, made up 92% of Nigeria’s small domestic wallet transfers below 10,000 dollars in the period, against 22% in the rest of the region. Even in the country that sets the pattern, a dollar token is one tool among several.
Do not set these figures beside last year’s. The 2025 edition had Nigeria receiving over 92.1 billion dollars in the twelve months to June 2025. The 2026 edition gives 38.1 billion and calls that a 3% fall, so the two cannot be measuring the same thing. The regional page does not explain the gap. The firm’s 2026 adoption index page speaks of “a new methodology” and sets out what the crypto economy now counts: outside crypto services, only stablecoins and smaller Bitcoin transfers. It also calls the result a lower bound. Read these numbers as a rough guide to activity. They do not show how many people save in dollars this way.
What you hold is a company’s promise, not a US bank deposit
A dollar in a US bank is a deposit, with federal deposit insurance up to a limit. A stablecoin is a claim on a private issuer, and that claim works through two markets. A Federal Reserve staff note keeps them apart: a primary market where the issuer creates and redeems tokens, and a secondary market where holders trade with each other.
For most people in Lagos or Nairobi the secondary market is the only one that counts. They buy from an exchange or a person, and they sell the same way. So the price they get depends on who is on the other side that day, as much as on the reserves. The promise may be honoured in full while a seller in a thin local market still takes a loss.
Local licensing can tighten this. Kenya’s Virtual Asset Service Providers Regulations, 2026 are the clearest example here: a holder has a claim on the issuer, reserves must at all times at least equal the tokens outstanding, and redemption at par must happen within two working days. That protects holders of a token from a Kenyan-licensed issuer. It gives no such right against the issuer of USDT or USDC unless that issuer takes a Kenyan licence.
Getting in and out: the ramp and its hidden premium
Most readers will enter through an exchange, a local app or a peer-to-peer market, paying a seller by bank transfer or mobile money. Those routes are explained in our guide to buying crypto in Africa and are not repeated here. Liquidity varies a lot: our guide on Cameroon counted 121 offers to sell USDT for CFA francs on Binance’s peer-to-peer market at 09:59 UTC on 26 October 2026, most of them paid through MTN Mobile Money. A count of offers is not legal cover: the same guide notes that Binance holds no licence from the regional market regulator, which has issued none.
The real price of a stablecoin in a controlled market is rarely one dollar. Take a made-up example: the official rate is 1,500 local units per dollar, and a seller asks 1,560 per USDT. That is a 4% premium on the way in. If you later sell at 1,500, the premium is gone, and a 3.8% yearly rate would need more than a year to pay it back. Reliable public figures for this spread are scarce, and it moves by the hour, so measure it yourself on the live order book on the day, in both directions, before comparing anything.
Country by country: five very different situations
Same token, different law. What follows is a dated summary of what each authority has published. Rules in this area change quickly, so check the regulator’s page before relying on it, and ask a local lawyer about your own case.
Nigeria: from bank ban to securities law
In February 2021 the Central Bank of Nigeria told banks not to operate accounts for crypto service providers. Its circular of 22 December 2023 replaced that instruction. Banks may now open designated accounts for firms registered by the Securities and Exchange Commission (SEC Nigeria), give settlement services and act as channels for foreign exchange flows. Banks themselves still may not hold or trade virtual currencies for their own account, and cash withdrawals from those designated accounts are not allowed.
The Investments and Securities Act, 2025, which carries the date 25 March 2025, lists virtual and digital assets in its definition of securities and tells the SEC to register and regulate virtual asset exchanges and service providers. The SEC has also published proposed rules that were still a draft when read on 2 November 2026. They would set categories of stablecoin and bar a service provider from offering any yield arrangement without the regulator’s authorisation. If that survives, it bears directly on earning interest through a Nigerian platform.
Chainalysis recalls that authorities temporarily restricted access to several international exchanges in 2024, amid concerns about the naira, and says fewer venues now offer naira pairs. Binance is the case most readers remember. Its executive Tigran Gambaryan was held for about eight months before prosecutors dropped the money-laundering charge against him on 23 October 2024. The charges against the company are allegations: Binance pleaded not guilty to the tax counts, and in a March 2026 hearing both sides told the court they were exploring a settlement, while a separate money-laundering case stayed before the same judge.
The rulebook is still moving. In July 2026 the president signed an executive order setting up a council chaired by the central bank to coordinate regulators, and Chainalysis reports that exchanges and custodians face higher capital requirements by June 2027. A Nigerian route that works today may not work next year.
Ghana: a law in place, licences to come
The Bank of Ghana says the Virtual Asset Service Providers Act, 2025 (Act 1154) is the basis for registering, licensing and supervising these firms. Its list of activities that need registration or a licence includes stablecoin issuance and virtual asset lending and borrowing, the second of which bears on any yield offered locally. When read on 2 November 2026, the application process section still said only that “this page will be available by the end of the third quarter of 2026”, a date already passed, and the page showed no list of licensed providers. A Ghanaian user should not assume that any given app is licensed. The cedi’s 2025 recovery in the table above is the other local lesson.
Kenya: a licensing deadline on 4 November 2026
The Virtual Asset Service Providers Act, 2025 (Act No. 20 of 2025) took effect on 4 November 2025, according to a public notice by the Central Bank of Kenya and the Capital Markets Authority. Section 47 of the Act gave existing providers one year from commencement to comply, which puts the deadline at 4 November 2026, two days after this lesson’s date. In that notice of 18 November 2025 the two regulators said they had licensed nobody yet, and that licensing would begin once regulations were issued.
Those regulations are now out, as Legal Notice 134 of 2026, dated 22 July 2026. According to an August 2026 alert by the law firm Oraro, the central bank supervises wallet providers, payment processors and stablecoin issuers, while the markets authority covers exchanges and brokers. Regulation 4 reaches foreign platforms too: anyone who targets Kenyan consumers or earns from Kenya counts as operating there, physical presence or not.
Two provisions touch a USDT or USDC holder directly. Regulation 60 says an exchange may not list a stablecoin unless the Central Bank of Kenya has approved it and a licensed issuer issues it. Regulation 83 lets the central bank direct licensed intermediaries to restrict access to, or trading of, a stablecoin issued outside Kenya. Neither names a token, so how they will apply to the two big dollar coins remains to be seen. Readers should look for a provider’s name on the regulators’ own lists after the deadline, and treat any claim of being licensed as unproven until they find it there.
Egypt: the strictest text of the five
The Central Bank of Egypt said in September 2022 that its law, No. 194 of 2020, prohibits issuing, trading or promoting cryptocurrency and creating or operating trading platforms. It gave the penalty as imprisonment and a fine of 1 million to 10 million Egyptian pounds, or one of the two, and said trading in Egypt is limited to official currencies. In its fourth warning, of March 2023, it added that no licence has ever been granted for such trading.
The pound’s fall from 15.6 to 49.2 per dollar between 2021 and 2025 explains the appeal. The statements explain the danger. An Egyptian reader faces a legal risk that a reader in Accra or Nairobi does not, and no yield figure in this lesson changes that.
The CFA franc zone: a weak case for inflation, a real one for payments
The CFA franc is tied to the euro at 655.957 francs per euro, and the table shows the result: inflation of 0.1% in Côte d’Ivoire and 1.5% in Senegal in 2025. So here the argument for a dollar token as an inflation shield is thin. The dollar rate simply follows the euro: a holder of dollars in Dakar lost about 4% in franc terms between the 2024 and 2025 averages. The appeal in the zone lies in getting paid from abroad and paying abroad, which is exactly the ground exchange rules cover.
In Central Africa, the banking commission COBAC issued decision D-2022/071 on 6 May 2022. As law professor Yvette Rachel Kalieu Elongo reads it, it binds supervised banks, microfinance and payment institutions, which may not acquire, hold, transfer or convert crypto-assets, and it does not bind individuals. It still bites them indirectly, because a local bank cannot be the exit. The BEAC and the IMF held a seminar on crypto-asset rules in Yaoundé from 23 to 27 February 2026, which produced no rule, so more text may come. Our guide to crypto in Cameroon and the CEMAC sets out each authority’s position, and West Africa has its own guide to Senegal, Côte d’Ivoire and the UEMOA, with a different central bank and different texts.
Exchange controls: where this lesson stops
Many of these countries restrict who can buy foreign currency and how much can leave. A stablecoin can look like a way round those limits, and regulators know it. Whether a given purchase or transfer breaks a rule depends on national law and on the facts: who you are, where you reside and what the money is for. This lesson does not suggest using a stablecoin to get round any control, and it gives no method for doing so. Failing to report export receipts, or moving funds to avoid a limit, may be an offence even where holding the token is not.
The CEMAC shows how far such rules reach. Article 37 of its exchange regulation, No. 02/18, requires residents to surrender to their bank the foreign-currency income they collect abroad. The text does not mention crypto, and no authority has published how it would treat a stablecoin balance. That silence is not permission. A resident paid in USDT by a foreign client should take that question to a lawyer first.
Earning interest on dollars: no rate is safe
The honest answer first: the benchmark is the Treasury bill
No dollar yield is safe, and that includes every rate in this lesson. The reference point is the short US Treasury bill, the least risky of them, because it pays for lending to the US government for a few weeks and little else. Many readers in these countries will have no easy way to buy one: it is the yardstick here, not a suggestion. Every rate below can be read against it, and rates change daily.
| Product | Rate | Date, source | Main thing you take on |
|---|---|---|---|
| US Treasury bill, 4 weeks | 3.91% discount, 3.98% coupon equivalent | 30 Oct 2026, US Treasury | US government credit |
| US Treasury bill, 13 weeks | 3.99% discount, 4.08% coupon equivalent | 30 Oct 2026, US Treasury | US government credit |
| US Treasury bill, 26 weeks | 4.11% discount, 4.25% coupon equivalent | 30 Oct 2026, US Treasury | US government credit |
| Aave v3 Ethereum, USDC supply | 3.79% | 2 Nov 2026, DefiLlama | Issuer, contract, liquidity |
| Aave v3 Ethereum, USDT supply | 3.78% | 2 Nov 2026, DefiLlama | Issuer, contract, liquidity |
| Aave v3 Arbitrum, USDC supply | 2.74% | 2 Nov 2026, DefiLlama | The same, plus the layer 2 |
| Aave v3 Base, USDC supply | 6.14% (5.36% base, 0.78% rewards) | 2 Nov 2026, DefiLlama | The same, plus rewards that can stop |
| sUSDS (Sky) | 3.80% | 2 Nov 2026, DefiLlama | Issuer design, contract, governance |
| Spark savings, USDC / USDT | 3.80% / 4.00% | 2 Nov 2026, DefiLlama | Contract, underlying strategies |
| stUSDS (Sky) | 9.47%, tagged Expert Mode | 2 Nov 2026, DefiLlama | Higher risk, read the terms first |
Sources: US Treasury daily bill rates, DefiLlama Yields. The coupon equivalent is the closer match to a yearly DeFi rate. Rates above are for one chain and one market each, and other Aave markets show different numbers.
The reading is short. The plainest DeFi options paid about 3.8% on 2 November 2026, slightly below the 4.08% of a 13-week bill. So the reader takes smart-contract and issuer risk for a rate that is, that day, lower than the yardstick. On a made-up 1,000 dollars, 3.8% is 38 dollars a year, before network fees and any ramp spread. Anything well above that level is paying for something: a subsidy, a thinner market or a further layer of risk.
Where the Aave rate comes from
Aave’s supply rate is what borrowers pay, minus the protocol’s reserve factor, according to its documentation. Our lesson on crypto lending and borrowing explains the mechanism. What matters for a saver is the withdrawal clause: you can take out only what is not currently lent. When most of a smart contract holding reserves of two or more tokens, supplied by users, that a decentralized exchange uses to execute trades automatically at a price set by a formula.">pool is borrowed, the money is yours but not available, which is the wrong moment to need it for rent.
Sky, Spark and yield-bearing tokens
The sUSDS token accrues the Sky savings rate directly: the token itself gains value against USDS, with no lending position to manage. About 4.48 billion dollars sat in it on Ethereum as of 2 November 2026, per DefiLlama. Our lesson on yield-bearing stablecoins covers how these tokens work. One point matters here: moving from USDT or USDC to USDS changes who you are trusting. You leave a company’s promise for a protocol’s design and its governance. The 9.47% listed for stUSDS, also from Sky, sits at the far end, and DefiLlama labels that pool Expert Mode. A rate that far above the bill means more risk, whatever the product is called.
Why the issuer itself pays you nothing
The law increasingly keeps interest away from the stablecoin itself. Section 4(a)(11) of the US GENIUS Act bars permitted and foreign issuers from paying any form of interest or yield solely for holding, using or keeping the token (see our calendar entry on when the Act takes effect). Articles 40 and 50 of the EU MiCA regulation go further, forbidding both issuers and crypto-asset service providers from granting interest, and they treat rewards linked to holding time as interest. Regulation 72 of the Kenyan rules follows the same model: neither issuers nor licensed providers may grant interest on a stablecoin, and rewards tied to holding time count as interest. So a yield on dollars comes from somewhere else, such as a borrower, a protocol or a separate savings contract, each with its own risk.
What the extra percentage pays for
| Risk | What happens | Who bears it |
|---|---|---|
| Issuer or reserve | The token trades under 1 dollar | Every holder, at once |
| Freeze | Your address is blocked by the issuer | The address holder |
| Smart contract | A bug or exploit drains a pool | Depositors, up to any backstop |
| Liquidity | You cannot withdraw until borrowers repay | Suppliers who need cash now |
| Ramp | Spread widens, a counterparty cheats, a bank acts | The local user |
| Legal and tax | A rule changes or was broken | You personally |
| Dollar inflation | The dollar itself buys less | Every holder, slowly |
The risks, one by one
Depeg: the USDC weekend of March 2023
On Friday 10 March 2023, Circle said it could not reach 3.3 billion dollars of USDC reserves at the failed Silicon Valley Bank. That was about 8% of roughly 40 billion dollars of reserves. Issuance and redemption depend on US banking hours, so the primary market largely stopped for the weekend, and the price fell on secondary markets: to as low as 87 cents, says the Federal Reserve’s May 2023 report, while a later Fed staff note puts the trough at 86 cents.
The rescue did not come from crypto. On 12 March the US Treasury, the Fed and the FDIC announced that all depositors of the bank would be protected. The price climbed back, and the peg returned only once Circle was processing redemptions again, from Monday 13 March. Supply on DefiLlama went from about 43 billion dollars on 10 March to about 35 billion on 21 March. Anyone forced to sell in Lagos or Accra that Saturday would have locked in the loss, and a holder in an emerging market had no part in the decision that saved the token.
Freezes by the issuer
An issuer can block addresses. Tether said on 23 April 2026 that it had helped the US government freeze 344 million USDT across two addresses, and that its work with more than 340 law-enforcement agencies in 65 countries has led to more than 4.4 billion dollars in frozen assets. The company describes these freezes as aimed at crime. It gives no count of bystanders, but a blocked address has no local branch to visit, and a peer-to-peer trade makes the other party’s history part of your risk.
Platform and smart-contract failure
Custodial apps can fail or close, and contracts can be exploited. Audits lower the odds and do not remove them. A local app that holds your balance adds one more company between you and the token. Our map of DeFi risks sorts these failures by type, and the first filter for a saver is simple: who can lose your money, and who would you call?
Ramp risk: spread, counterparties, bank accounts
This is the risk that bites most often and appears in no protocol dashboard. A peer-to-peer buyer can reverse a payment. A bank can question a run of transfers from strangers, or close the account. Mobile money limits can cap what you can withdraw in a day. The spread can widen just when you need to sell, because everyone else wants the same exit.
Regulatory and tax risk
For readers in the five regions above, local tax treatment varies and may be unsettled: ask a local adviser. A reader in the United States who holds or sends stablecoins has clearer rules. The IRS treats digital assets as property and lists stablecoins among them. Selling or exchanging them, or paying for goods with them, must be reported, while holding them or moving them between your own wallets does not need to be, unless you pay a fee in digital assets. Our guide to US crypto taxes has the detail. In the UK, HMRC’s cryptoassets manual handles individuals’ holdings under capital gains tax, and our UK guide applies it. Someone sending dollars home should keep records on both sides.
The risk the title hides: the dollar loses value too
A stablecoin protects against the naira falling against the dollar. It does not protect against the dollar falling against what things cost, the subject of our lesson on inflation and purchasing power. US consumer prices rose 8.0% in 2022, 4.1% in 2023 and 2.9% in 2024, per the World Bank. It also leaves you exposed if your costs are local and your currency recovers, as the cedi did in 2025.
Four questions to ask before any rate
There is no right share of savings to hold this way, and this lesson will not give one. Is holding this token legal for me, here, today? Can I name who owes me the dollar? Do I know the current spread in both directions? How fast can I get back to local money on a bad day, and through whom?
Money needed for rent, school fees or stock is a poor candidate for any yield product, because a yield product’s worst day and yours may coincide. The cases where a stablecoin helps most tend to be practical: getting paid by a foreign client, holding a working balance for a short time, paying a supplier abroad, each only where local exchange rules allow it. The next lesson on sending money looks at that use, with the real cost of each leg.
