The European Central Bank (ECB) has issued a direct warning regarding how the rapid growth of stablecoins could reshape global finance, increase risks for traditional banks, and strengthen the international dominance of the U.S. dollar.
According to an official ECB statement, Executive Board Member Isabel Schnabel told attendees at the 2026 Bank of Korea International Conference in Seoul on June 1, 2026, that the rise of stablecoins mirrors earlier financial innovations, including money market funds and historical forms of privately issued money.
While acknowledging the benefits of blockchain-based payments and tokenization, Schnabel stressed that regulators and central banks must adapt quickly to maintain financial stability and monetary control.
Stablecoins growing beyond crypto trading
Stablecoins are privately issued digital tokens typically pegged to fiat currencies and backed by reserve assets such as government bonds, bank deposits, or cash equivalents.
According to Schnabel, global stablecoin market capitalization has climbed to nearly $300 billion, with dollar-backed stablecoins dominating the sector. Tether (USDT) and USD Coin (USDC) alone account for roughly 90% of the market.
She noted that stablecoins are increasingly viewed as a tool for instant settlement, programmable payments, and cross-border transfers, although crypto trading remains their primary use case.
Risks of bank disintermediation
A key concern highlighted by the ECB is the potential impact of stablecoins on traditional banking.
Schnabel warned that if consumers and businesses begin moving funds from bank deposits into stablecoins, banks could face a less stable funding base and become increasingly dependent on wholesale markets. According to her, such a shift could make banks’ liabilities more concentrated, rate-sensitive, and volatile, potentially increasing vulnerabilities across the financial system.
Drawing comparisons with money market funds, she noted that stablecoins could trigger a new wave of bank disintermediation even though most major stablecoins currently do not offer direct interest payments.
Run risks and market contagion
The ECB also highlighted the risk of stablecoin runs, comparing them to money market fund crises seen during the 2008 financial crash and the COVID-19 market turmoil.
According to Schnabel, confidence in reserve assets remains critical. If investors begin questioning the quality or liquidity of stablecoin reserves, mass redemption requests could force issuers to liquidate assets quickly, potentially creating broader market disruptions.
She pointed to Tether’s exposure to assets such as commodities, loans, and crypto holdings as a potential source of concern, while noting that USDC’s reserve structure could create spillover effects in government bond markets during periods of stress.
“Stablecoins are also subject to the risk of runs,” Schnabel said, adding that their 24/7 settlement nature could allow financial stress to spread much faster than in traditional markets.
Unintentional digital dollarization
One of the most significant geopolitical elements of Schnabel’s address focused on currency dominance. Because the stablecoin ecosystem is overwhelmingly dominated by tokens pegged to the U.S. dollar, its adoption introduces structural dollarization by default.
In emerging economies experiencing high domestic inflation or structural currency weakness, residents may increasingly hold dollar-denominated stablecoins instead of local currencies, reducing the effectiveness of domestic monetary policy and increasing dependence on the U.S. financial system. “The growing use of stablecoins may further cement the international dominance of the U.S. dollar,” Schnabel warned.
ECB pushes digital euro and tokenized central bank money
Rather than resisting innovation, Schnabel said central banks should focus on modernizing public financial infrastructure.
The ECB is advancing two major initiatives: the digital euro for retail payments and tokenized central bank money for wholesale financial markets.
According to Schnabel, a digital euro would help preserve public access to central bank money, reduce Europe’s reliance on foreign payment providers, and strengthen the region’s financial sovereignty.
At the wholesale level, the ECB is developing projects such as Pontes and Appia to support tokenized financial transactions while maintaining settlement in central bank money.
She emphasized that the benefits often attributed to stablecoins stem primarily from blockchain technology itself rather than the stablecoin instruments. “Many of the advantages of stablecoins arise from the technology on which they are based rather than from the characteristics of the instrument itself,” Schnabel said.
The bigger picture
The ECB’s latest assessment signals that stablecoins are no longer viewed as a niche crypto product but as a potential force capable of reshaping global finance.
While acknowledging their role in improving payment efficiency and fostering innovation, Schnabel stressed that regulators must establish strong guardrails around reserve quality, transparency, redemption mechanisms, and risk management.
“History has shown that once private forms of money are widely adopted, they shape the structure of the financial system in ways that can be difficult to reverse,” she concluded.
As stablecoin adoption accelerates worldwide, the ECB’s message is clear: innovation should continue, but it must evolve within a framework that safeguards financial stability, preserves monetary control, and protects the long-term role of sovereign currencies.
