[ND Analysis] IMF Warns of the Flip Side of Dollar Stablecoins: At the Crossroads of FX Access and Currency Bank Runs

As of July 11, 2026, the latest working paper released by the International Monetary Fund (IMF) highlights key financial stability challenges in the digital asset era. It points out that while dollar-pegged stablecoins serve as an essential financial lifeline in economies with limited foreign currency access, they are also designed to accelerate currency bank runs that destabilize emerging economies.

This analysis suggests that while stablecoins can be a means of asset protection for individual users, from a macroeconomic perspective, they can threaten a nation's monetary sovereignty. Particularly in markets with extreme exchange rate volatility, the rapid mobility of digital assets acts as a catalyst for capital outflows at a speed that traditional financial systems find difficult to counter.

The IMF report focuses on the "coordination" function of stablecoins. This refers to the phenomenon where users simultaneously sell local currency and convert to digital dollars during periods of heightened economic uncertainty, further deepening the depreciation of a specific country's currency and capital flight.

The stablecoin market, led by Tether (USDT) and USD Coin (USDC), grew rapidly from less than $5 billion in 2019 to surpass $300 billion in October 2025. However, in June 2026, the stablecoin market capitalization fell to $312 billion, recording the largest monthly decline since the collapse of TerraUSD, revealing the market's vulnerabilities.

Mechanisms of Instability: Spillover Effects and Parity Deviations

According to a 2026 joint study by the IMF and the Bank for International Settlements (BIS), stablecoin flows have a substantial economic impact on foreign exchange markets. While a specific shock might only cause the broad dollar index to decline by about 0.09%, it triggers a rebalancing of global portfolios, exerting greater pressure on emerging market currencies.

• Increased sensitivity of US Treasury yields and amplification of market stress due to the sale of reserve assets by issuers.
• Persistent parity deviations observed in an analysis of 27 fiat currencies.
• Amplification of shocks due to concentration in wholesale markets and the occurrence of so-called 'run externalities'.

In particular, the report warned of the risks that arise when stablecoin issuers conduct fire sales of their reserve assets to meet large-scale redemption demands. Such asset sales result in amplifying stress not only in the specific asset market but across the entire connected financial system, ultimately leading to liquidity crises in emerging markets.

This phenomenon was particularly prominent in the analysis of 27 fiat currencies with insufficient foreign exchange reserves. The IMF's analysis suggests that because capital movement in a digital environment has no physical limits, traditional capital control measures are highly likely to be rendered ineffective.

Regulatory Pathways: The 'Full-Service Model' and Global Frameworks

To mitigate risks, the IMF proposed a 'Full-service model.' This approach involves backing stablecoins 100% with central bank deposits and granting issuers access to central bank settlement systems to ensure both safety and interoperability. This structure is similar to the so-called 'narrow banking' model.

While the price volatility of stablecoins currently remains within a relatively stable range, the quantitative scale of capital flows has increased approximately twofold since the beginning of the war in Ukraine. This implies that the potential shock energy in the market has accumulated to a much greater extent than in the past, signaling a time that requires agile responses from central banks.

In conclusion, global financial authorities must manage stablecoins not merely as a means of payment but as a key variable for financial stability. Future regulatory frameworks are expected to focus on strengthening the asset transparency of issuers and establishing liquidity supply systems during crises, guiding digital assets to become assistants rather than disruptors of the monetary system.
