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, according to Dutch central bank governor Olaf Sleijpen.
In a Financial Times interview, Sleijpen that the fast-growing dollar-pegged stablecoins could become systemically relevant to Europe’s financial ecosystem. He said that if the tokens were to destabilize, they could affect financial stability, the wider economy and even inflation.
“If stablecoins are not that stable, you could end up in a situation where the underlying assets need to be sold quickly,” he said, underscoring that rapid liquidation could amplify stress across markets.
Sleijpen said the ECB may be forced to “rethink monetary policy” if the shocks were strong enough. However, he emphasized that it was unclear whether such a scenario would need rate hikes or cuts.

In April, the US Department of the Treasury reported that evolving market dynamics have the potential to accelerate the growth of stablecoins. The Treasury predicted that stablecoins by 2028.
Sleijpen said that as dollar-pegged stablecoins continue to grow, the sector could reach a scale where their fluctuations would directly matter to Europe’s economic outlook.

While concerns over stablecoins were apparent, Sleijpen’s comments highlight a more pressing concern: that stablecoin issuers could become vectors for financial instability. If large issuers offload reserves at scale, a contagion could extend into liquidity conditions, asset prices and inflation.
