Stablecoins in Africa: why Nigeria has become the world capital of the digital dollar

Daniel Platteau crypto

When a currency collapses, people find an alternative. In Nigeria — and in much of Africa — that alternative is USDT.

In 2025, Nigeria ranks 6th in the world in the cryptocurrency adoption index published by Chainalysis. That figure alone does not tell the whole story. What is really striking is that the country accounts for 60% of stablecoin inflows into sub-Saharan Africa since 2019, according to the IMF. And between July 2024 and June 2025, it received $92 billion in on-chain crypto value — nearly three times as much as South Africa, which is nonetheless second on the continent.

This is not a tech fad. It is a concrete economic response to very real problems.

What these figures really reveal

Chainalysis's adoption indices do not just measure raw volumes. They weight the data by population size and level of wealth, and give particular weight to small transactions — those made by individuals and small businesses. In other words, Nigeria is not in this ranking because hedge funds churn billions there. It is there because millions of ordinary people use crypto every day.

In 2025, around 22 million Nigerians — 10.3% of the population — held crypto-assets. Among Nigerian adults who have invested in crypto, 52% are under 30. And USDT (Tether) alone accounts for 88.5% of the stablecoins in circulation in the country.

Across the continent, stablecoins now account for 43% of total crypto transaction volume in sub-Saharan Africa — a region that processed more than $205 billion on-chain between July 2024 and June 2025, a 52% increase in one year.

Why stablecoins rather than the local currency?

To understand the enthusiasm, you have to understand the macroeconomic context.

The Nigerian naira has lost a considerable share of its value in recent years. Inflation has regularly exceeded 20 to 30%. Access to dollars through official banks is subject to restrictions, delays and exchange rates that are often less favourable than on the parallel market. In this context, holding USDT or USDC means accessing a form of digital dollar: stable, transferable in seconds, with no bank clerk and no forms.

A Nigerian importer buying goods in China can send USDT in ten minutes, for less than a dollar in fees, on the Tron network or BNB Smart Chain. The same operation through their bank would take several days, cost much more, and could be blocked by currency restrictions.

How does it work in practice?

P2P, the backbone of the system

The most widespread use remains peer-to-peer trading. On platforms such as Binance P2P, Bybit, Yellow Card or local Telegram groups, a user buys USDT by paying in naira via mobile transfer or mobile money. They can then:

• send these stablecoins to a supplier abroad;
• keep them as a store of value;
• sell them back for local currency when they need it.

This circuit completely bypasses the traditional banking system. That is its strength, and also its weakness.

African fintechs as intermediaries

Local players have built bridges between crypto and the real economy:

• Yellow Card: buying and selling stablecoins in more than 20 African countries, with an interface designed for non-specialists.
• AZA Finance (formerly BitPesa): cross-border B2B payments via crypto, particularly for SMEs.
• Fluidcoins: stablecoin payment infrastructure for Nigerian businesses.

These players have understood that real demand is not speculative. These are payment and protection tools, not bets on bitcoin going up.

Low-cost networks, the key to mass adoption

An often overlooked point: African stablecoins rarely circulate on Ethereum, whose fees are prohibitive for small amounts. The preferred networks are Tron, BNB Smart Chain and Polygon, where a transfer costs a few cents, even for hundreds of dollars. That is what makes everyday use possible for low-income households.

Remittances: a transformed market

Nigeria receives more than $20 billion in diaspora transfers each year. These flows are vital for millions of families. Historically, they went through Western Union, MoneyGram or banks — with fees that could exceed 7 to 10% and delays of several days.

Stablecoins change the game. A Nigerian in the United Kingdom sends USDT to their family in Lagos in a few minutes, for a few cents. The recipient can keep the stablecoins (to protect themselves from inflation) or convert them into naira via a local P2P platform.

The IMF acknowledges this positive effect — while stressing that these flows now escape official foreign exchange statistics, which complicates macroeconomic management.

Real risks not to be underestimated

Silent currency substitution

When millions of citizens keep their savings in USDT rather than naira, demand for the national currency weakens. The central bank loses part of its ability to steer the economy: its rate hikes have less effect if economic agents manage their wealth outside the system. This is what the IMF calls the risk of currency substitution — an informal digital dollarisation.

Easier capital flight

Stablecoins also make it possible to move value out of the country quickly and discreetly. Naira converted into USDT, then transferred to an international platform, constitutes a capital outflow that central banks struggle to trace. It is not the dominant use, but it is a real risk to financial stability.

Fraud and scams

Enthusiasm for crypto amid high unemployment also attracts fraudsters. Dozens of Ponzi schemes present themselves in Nigeria dressed up as blockchain projects, promising extraordinary returns and targeting unemployed young people. The losses can be devastating for households that are already in a precarious position.

Dependence on foreign infrastructure

USDT is issued by Tether, a private company operating outside Nigeria. If Tether freezes accounts, faces a regulatory crisis or loses its peg to the dollar, Nigerian holders have no recourse to a national institution. Using foreign stablecoins as one's main savings exposes people to counterparty risks over which the Nigerian state has no control.

The state's response: between prohibition and experimentation

Faced with this massive adoption, Nigeria has adopted a two-pronged strategy.

On the one hand, the Central Bank (CBN) long prohibited banks from dealing with crypto-assets (2021), before relaxing this position at the end of 2023. The aim: to limit the regulated banking system's exposure without completely closing the door on innovation.

On the other hand, Nigeria launched the eNaira in October 2021, the world's second central bank digital currency (CBDC) after the Bahamas' Sand Dollar. The eNaira is a digital version of the naira, issued directly by the central bank and accessible via smartphone. Its stated goal: to modernise payments, promote financial inclusion and offer a sovereign alternative to private stablecoins.

The result? Adoption of the eNaira has remained marginal. Users overwhelmingly prefer USDT, for a simple reason: the eNaira is still pegged to an unstable naira. It does not solve the underlying problem.

In April 2025, Nigeria took an important step by officially recognising digital assets as securities through the Investments and Securities Act (ISA 2025). A regulatory framework is starting to take shape — but the market had already voted years earlier, with its behaviour.

Nigeria, driving a wider African movement

The Nigerian case is not isolated. It foreshadows what other African economies are experiencing:

• Ghana: the cedi has lost much of its value in recent years. Stablecoin adoption is progressing there along identical lines.
• Kenya: strong P2P adoption despite official reluctance. A regulatory bill was already under discussion in 2024.
• South Africa: a more regulated market, but significant use for cross-border payments.
• French-speaking countries (Senegal, Côte d'Ivoire, DRC): growth is slower, but remittances are starting to flow through stablecoins, particularly via platforms such as Yellow Card.

Across the continent, stablecoins are becoming an informal pan-African payment infrastructure — a way of getting around the inconvertibility of local currencies with one another and the prohibitive costs of regional interbank transfers.

What this changes for monetary geopolitics

There is an often forgotten dimension to this story: by adopting USDT and USDC on a massive scale, Africa is indirectly strengthening the hegemony of the US dollar — no longer through banks, but through private digital infrastructure.

Stablecoin issuers (Tether, Circle) hold colossal reserves in US Treasury bills. Every USDT bought in Lagos helps finance US debt. It is a form of silent dollarisation, carried out by private players, without the US government having had to negotiate anything.

This raises an important strategic question for African states: should they develop local alternatives — stablecoins backed by African currencies, or regional CBDCs? Nigeria's eNaira project, discussions around a cNGN naira stablecoin backed by private reserves, and reflections within the CFA franc zone are all embryonic answers to this question.

Conclusion: an alternative monetary infrastructure is being born

What the Nigerian data reveal is that stablecoins are no longer just speculative tools or niche instruments for blockchain enthusiasts. In economies where the local currency no longer properly fulfils its functions — store of value, means of international payment, access to foreign currency — they have become a substitute monetary infrastructure.

The consequences are twofold and inseparable. On one side: financial inclusion, lower transfer costs, protection against inflation, dynamic local fintechs. On the other: a weakening of national monetary policy, fraud risks, dependence on foreign private issuers, potential capital flight.

The most likely — and most desirable — scenario is neither prohibition (ineffective and politically costly) nor complete laissez-faire (dangerous for stability), but regulated integration: clear legal frameworks, stronger consumer protection, and CBDCs attractive enough not to leave the whole field to foreign private stablecoins.

In the meantime, 22 million Nigerians have already decided. And their neighbours are watching.
