ESMA Warns of Growing Crypto-Financial-System Linkages and DeFi Spillover Risk

ESMA’s September 10 risk report says increasingly vulnerable crypto markets are becoming more connected to the broader financial system, recent DeFi exploits renew spillover concerns, and tokenised equities are gaining momentum.

September 11, 2026Last updated 10:30 UTC2 min read

ESMA’s second risk-monitoring report of 2026 adds crypto, DeFi and tokenisation to a broader warning about stretched valuations and financial-system vulnerability.

The key crypto point is not a new MiCA rule.

It is interconnection risk.

Crypto is increasingly connected to traditional finance

ESMA says risks warrant close monitoring in the growing linkage between increasingly vulnerable crypto-asset markets and the broader financial system.

Potential channels include investment products, tokenised securities, stablecoin/payment exposure, institutional custody, interconnected trading venues, collateral and leverage.

DeFi exploits renew spillover concern

ESMA says recent DeFi exploits have renewed concerns about interconnectedness and potential spillovers.

Tokenised equities

ESMA says tokenisation of equities remains at an early stage but adoption momentum is increasing.

Wider market-correction warning

ESMA also warns that strong investor optimism and elevated valuations are diverging from weaker macro-financial conditions.

Operational and cyber risk

ESMA also highlights rising operational risks, including cyber risk and frontier-AI-related threats.

What ESMA did not do

The September 10 report did not ban tokenised equities, ban DeFi, impose a new MiCA restriction, designate one crypto firm or announce one enforcement case.
