Introduction
Olaf Sleijpen, governor of the Dutch central bank, has voiced concerns that the European Central Bank (ECB) may soon be compelled to view stablecoins not just as a regulatory concern, but also as a potential source of macroeconomic shocks.
Impact of Stablecoins on the European Economy
In a Financial Times interview, Sleijpen cautioned that fast-growing dollar-pegged stablecoins could become systemically relevant to Europe’s financial ecosystem. He stated that if these tokens were to destabilize, they could affect financial stability, the broader economy, and even inflation.
Sleijpen underscored that rapid liquidation could amplify stress across markets, saying, "If stablecoins are not that stable, you could end up in a situation where the underlying assets need to be sold quickly."
Rethinking Monetary Policy
Sleijpen suggested that the ECB might be forced to "rethink monetary policy" if the shocks were strong enough. However, he emphasized that it remained unclear whether such a scenario would necessitate rate hikes or cuts.
Growth of the Stablecoin Market
Sleijpen’s comments arrive amidst a year of explosive growth for the stablecoin sector. CoinGecko data reveals a nearly 50% increase in stablecoin market capitalization this year. As of the current writing, stablecoins hold an overall valuation of $310 billion.
- Tether’s USDt (USDT), the leading US dollar-pegged stablecoin, has grown from a $127 billion market cap in November 2024 to a $183 billion market cap over the past year, marking a 44% increase.
- USDC (USDC), the second-largest stablecoin asset, has grown by nearly 100% from $37 billion to $74 billion during the same period.
US Treasury Department's Projections
In April, the US Department of the Treasury reported that evolving market dynamics could accelerate the growth of stablecoins. The Treasury projected that stablecoins might reach a $2 trillion market cap by 2028.
Impact of Dollar-Pegged Stablecoins on Europe
Sleijpen stated that as dollar-pegged stablecoins continue to expand, the sector could reach a scale where their fluctuations directly impact Europe’s economic outlook.
Concerns Regarding Dollar-Backed Stablecoins in Europe
In April, ECB Executive Board member Piero Cipollone authored an article highlighting concerns about the growth of dollar-backed stablecoins. He argued that launching a central bank digital currency (CBDC) could help preserve monetary sovereignty in the eurozone. He added that a digital euro could limit the potential for foreign currency stablecoins to become a more common medium of exchange in Europe.
Threat to Financial Standing
Italy’s Minister of Economy and Finance, Giancarlo Giorgetti, also expressed apprehensions regarding US dollar stablecoins. In April, Giorgetti stated that stablecoins pose a greater threat to European financial stability than trade tariffs.
Conclusion
While concerns surrounding stablecoins have been evident, Sleijpen’s comments underscore a more pressing concern: that stablecoin issuers could become conduits for financial instability. If large issuers were to offload reserves at scale, a contagion could spread to liquidity conditions, asset prices, and inflation. In September, Nobel Prize-winning economist Jean Tirole warned that governments could face multi-billion-dollar bailout pressures if major stablecoins were to collapse.
