IMF: Local-Currency Stablecoins May Accelerate Digital Dollarization

IMF First Deputy Managing Director Dan Katz has warned that emerging markets attempting to fight the dominance of the U.S. dollar through local-currency stablecoins may actually speed up the process of dollarization. Speaking at the University of Cape Town, Katz argued that these digital assets could serve as a bridge rather than a barrier, making it easier for citizens to exit their domestic currencies.

The core of the risk lies in the technical ease of on-chain transactions. Katz noted that local-currency stablecoins allow users to swap into dollar-backed tokens directly on the blockchain, a process that occurs outside the traditional banking system and away from established foreign exchange dealers. By moving these transactions on-chain, users can effectively bypass national capital controls designed to stabilize domestic currencies.

The USD Dominance

This warning comes as the global stablecoin market remains overwhelmingly centered on the U.S. dollar. According to IMF data, nearly 99 percent of all stablecoins are currently denominated in USD. This dominance is reinforced by the underlying architecture of the market, where stablecoin reserves are primarily held in short-term U.S. Treasury bills and reverse repurchase agreements.

Emerging economies have historically viewed local-currency stablecoins as a defensive tool to maintain monetary sovereignty. The goal was to provide a digital alternative that would keep capital within the domestic ecosystem and reduce the reliance on USD-pegged tokens for daily commerce and savings.

Risks to Monetary Policy

If local stablecoins act as a frictionless gateway to dollar tokens, the result is "digital dollarization." This shift significantly weakens the ability of central banks to manage their own money supply and control exchange rates. When a large portion of the population shifts their holdings into dollar-backed assets, the domestic central bank loses its primary levers for managing inflation and responding to economic shocks.

For volatile economies, this loss of control can lead to increased financial instability. As capital flows more freely into USD tokens, the domestic currency may face intensified downward pressure, creating a feedback loop that further incentivizes the abandonment of the local currency.

The Path Forward

As emerging markets continue to explore Central Bank Digital Currencies (CBDCs) and regulated stablecoins, the IMF suggests that the design of these assets must account for the existing USD-centric nature of the crypto ecosystem. The challenge for policymakers is to create digital tools that offer efficiency without providing a backdoor for capital flight.

Whether central banks can implement effective guardrails on-chain remains a critical question. For now, the IMF's position is that without careful coordination, the very tools meant to protect monetary sovereignty could become the instruments of its erosion.
