Nigeria isn’t just dabbling in stablecoins. It’s practically running the sub-Saharan Africa playbook on them, and the International Monetary Fund is now sounding the alarm about what that means for the country’s monetary sovereignty.

In a June 2026 analysis titled “Stablecoins in Nigeria: A Growing Cross-Border Channel,” IMF researchers laid out the scale of the phenomenon: Nigeria has accounted for approximately 60% of sub-Saharan Africa’s stablecoin inflows since 2019. The country received around $59 billion in crypto-asset inflows between July 2023 and June 2024, with stablecoin transaction volumes alone nearing $22 billion during that same window.

Why Nigerians turned to stablecoins

Nigeria’s naira has been on a prolonged slide, eroding purchasing power and making dollar-denominated assets enormously attractive. The Central Bank of Nigeria made things worse in 2021 by restricting banks from dealing with cryptocurrency firms, which paradoxically pushed more users toward peer-to-peer platforms and self-custodied wallets.

USD-pegged stablecoins became the workaround. Nigerians use them for remittances, cross-border trade, and as a store of value when the naira wobbles. The IMF researchers acknowledged this directly, noting that stablecoins emerged partly as a response to naira depreciation and the CBN’s own restrictive policies.

Nigeria ranked second globally on Chainalysis’s 2024 Crypto Adoption Index. By 2025, it had slipped to sixth, but that still places it among the most crypto-active nations on the planet.

The IMF’s core concern: digital dollarization

The IMF’s warning centers on what happens when stablecoins replace the local currency in daily economic life. If enough Nigerians transact, save, and price goods in USD stablecoins rather than naira, the Central Bank of Nigeria loses its ability to influence the economy through monetary policy. Interest rate changes, money supply adjustments, inflation targeting: all of these tools become less effective when a significant chunk of the economy operates in a currency the central bank doesn’t control.

IMF researchers were blunt about one key point. Efforts to suppress stablecoin use are “likely to be only partly effective.” Instead, the fund recommended a balanced approach: encourage innovation while strengthening regulatory oversight and improving data collection on stablecoin flows. Much of Nigeria’s stablecoin activity flows through decentralized channels that are difficult for regulators to monitor, which creates blind spots for both monetary policy and financial integrity.

The IMF also stressed that the credibility of domestic economic policy itself is the best defense against digital dollarization.

cNGN and Nigeria’s regulatory pivot

In early 2025, the Nigerian Securities and Exchange Commission authorized the launch of cNGN, which became Africa’s first regulated naira-pegged stablecoin.

The CBN banned banks from servicing crypto firms in 2021, then the SEC gradually moved toward creating a licensing framework. The authorization of cNGN represents the latest chapter in that pivot from prohibition to managed integration. The IMF recommends alignment with international regulatory frameworks rather than outright suppression.

What this means for investors

With 60% of sub-Saharan stablecoin inflows flowing through one country, any regulatory shift in Nigeria reverberates across the continent.

For stablecoin issuers like Tether and Circle, Nigeria represents one of their most important organic growth markets, driven by genuine retail demand from remittances and cross-border trade rather than speculative activity.

The deeper signal from the IMF’s analysis is that stablecoins have crossed from being a crypto-native curiosity to a macroeconomic variable that central banks and international institutions now track alongside traditional capital flows. For a country processing nearly $22 billion in stablecoin volume annually, these are active policy challenges that will shape how the next generation of crypto regulation develops.
