Residents of developing economies are increasingly turning to dollar-denominated stablecoins to safeguard their savings, settle payments across borders, and obtain value in other currencies — a shift that is pushing stablecoin adoption well beyond the cryptocurrency sphere. Stablecoins are blockchain-based tokens engineered to hold a steady value against a reference asset, most often the US dollar, which makes them a practical digital stand-in for hard currency.

Recent research by the International Monetary Fund (IMF), spanning 188 countries and documenting $21.4 trillion worth of stablecoin transactions from 2018 to 2025, illustrates how economic distress has accelerated the trend (IMF working paper). The findings point to a change in the way people hold US dollars: rather than relying on traditional channels such as cash or a US bank account, individuals can now hold a dollar-pegged stablecoin in a wallet and move it anywhere in the world. For observers of payments and monetary policy, the data matter because they put hard numbers on a dollar-access channel that runs alongside the traditional banking system.

Stablecoin Adoption Rises When Currency Pressure Builds

The IMF data reveal a strong link between stablecoin usage and periods of financial distress. Approximately 75 percent of stablecoin holdings are concentrated in emerging and developing countries, a sign that adoption is highest in regions outside the developed world.

Usage also tends to climb when governments impose capital controls — measures that restrict how easily residents can convert local currency into foreign currency. According to the research, stablecoin activity increases by about 30 percent in the six months following the introduction of capital controls.

A currency crisis has an even more pronounced effect. Stablecoin use rises by roughly 75 percent over the course of a year after a currency crisis occurs, and part of that elevated level persists even after conditions improve. The pattern indicates that stablecoins are being used not only as a means of transferring money, but as a financial instrument in their own right — and that adoption triggered by distress can outlast the distress itself.

Where a local currency depreciates or access to foreign currency is difficult, dollar-denominated stablecoins serve as an alternative. Users can effectively hold digital dollars without ever opening a conventional US dollar bank account. Taken together, the figures suggest that stablecoins absorb demand for dollars precisely when conventional routes to foreign exchange become more difficult.

Nigeria Highlights the Digital Dollarization Trend

Nigeria provides one of the clearest illustrations of the dynamic. According to the IMF's Nigeria Report 2026, stablecoins accounted for more than 65 percent of the country's crypto inflows in 2024 (IMF eLibrary). Dollar-pegged stablecoins have gained popularity in the country for their role in moving money across borders and storing foreign currency without going through the domestic banking system.

Nigeria has been under sustained pressure to devalue its national currency, the naira, even as the economy continues to require foreign exchange. In that environment, stablecoins have become a practical bridge to hard currency. Companies use them to settle international payments, while individuals rely on them for remittances or to protect savings from the devaluation of the local currency.

The Nigerian experience shows how quickly stablecoin adoption can grow when access to foreign currencies is constrained — a pattern the IMF's cross-country data suggest is widespread across emerging economies rather than unique to one market — and it helps explain why the phenomenon is attracting growing interest in the field of monetary policy.

Central Banks Are Watching Stablecoin Adoption

Rising stablecoin uptake has raised new challenges for central banks and turned the assets from a niche crypto product into a subject of formal policy discussion. Petra Tschudin, a member of the Swiss National Bank's board, said on September 30 that extensive adoption of stablecoins could hamper the effectiveness of monetary policy (Reuters). The concern is that people will move deposits held at commercial banks into stablecoins.

The tension stems from the structure of the financial system: commercial banks depend heavily on deposits to fund lending, while central banks depend on interest rates to influence the economy. If more funds flow into stablecoins, some of these operations may migrate to channels outside traditional banking.

The problem becomes especially acute when stablecoins are issued in foreign currencies. Greater interest in dollar-denominated stablecoins can reduce demand for the domestic currency and weaken the impact central banks have on national financial conditions. The Swiss comments underline how the conversation has shifted from crypto-market circles to the institutions that set interest rates and oversee banking systems.

Stablecoins Are Becoming More Than Crypto Assets

The adoption reflects a demand for faster payments and greater access to dollars. Stablecoins allow value to be transferred without full dependence on traditional financial systems, offering companies an additional option for settling transactions internationally and giving individuals access to dollar-based assets through digital wallets.

Increased usage, however, carries risks related to financial sovereignty and stability. Domestic currencies could face heightened competition if stablecoins become a widespread store of wealth in developing countries where the local currency is not strong.

The IMF study ultimately highlights a larger shift. Stablecoins are no longer limited to trading on crypto exchanges or facilitating blockchain transactions; they are being widely adopted in some countries as a way to gain access to the US dollar. As adoption rises, digital dollars may influence banking, international payments, foreign exchange demand, and monetary policy. With the dataset running through 2025 and central banks now commenting publicly, forthcoming IMF research and policy statements will be the places to watch for how the trend develops and how authorities respond. For many people, digital dollars simply provide easy access to dollar value.
