Stablecoin adoption introduces structural risks to financial stability, requiring central banks to counter them with robust regulation and central bank digital currencies (CBDCs). Speaking Monday at the 2026 Bank of Korea International Conference in Seoul, European Central Bank (ECB) executive board member Isabel Schnabel warned that the $300 billion stablecoin market is highly susceptible to run risks due to liquidity mismatches. Schnabel also emphasized that dollar-denominated stablecoins risk cementing US dollar dominance globally, effectively amplifying the international transmission of US monetary policy while sidelining the euro.
To secure European strategic autonomy, Schnabel advocated for the digital euro, a retail CBDC intended to preserve public access to central bank money through a unified, legal-tender payment network. The ECB plans a potential initial issuance by 2029, following targeted regulations later this year. This proactive stance contrasts with the United States, where Treasury Secretary Scott Bessent recently confirmed the administration will block a domestic CBDC, favoring private stablecoin rules instead.
Meanwhile, the European crypto ecosystem is shifting under the Markets in Crypto-Assets (MiCA) framework, which faces a formal policy evaluation closing August 31, 2026. Coinbase’s international policy director, Katie Harries, praised the baseline rules but urged the EU to adjust strict reserve requirements. Harries argued that forcing issuers to hold up to 60% of reserves in commercial bank deposits concentrates systemic risk, recommending a pivot toward higher-quality sovereign bonds to ensure safer market competition.
