Large-Scale Review of Crypto Custody Systems Launched Across Europe
The European Securities and Markets Authority (ESMA) announced the launch of an EU-wide supervisory review of the digital operational resilience of Crypto-Asset Service Providers (CASPs) offering custody services.
ESMA launched a Common Supervisory Action (CSA), under which national regulators will assess how effectively authorized CASPs ensure digital operational resilience when safeguarding client assets.
The review will cover a risk-based sample of CASPs. It will focus on the maturity of internal digital risk management frameworks supporting custody services. In particular, regulators will assess:
- corporate governance frameworks;
- cryptographic key management and asset storage infrastructure;
- transaction controls;
- incident detection and response mechanisms;
- smart contract risks;
- companies’ reliance on third-party technology and service providers.
The initiative will run from the second half of 2026 through the first half of 2027.
According to ESMA, the review reflects its current risk-based supervisory priorities, which identify digital operational resilience and Crypto-Asset Service Providers as key supervisory focus areas. The regulator expects a harmonized supervisory approach to strengthen supervisory convergence across the rapidly evolving digital asset sector.
Once the review is completed, national competent authorities will submit their findings to ESMA. The regulator will then consolidate the results into a final report, which is scheduled to be presented to ESMA’s Board of Supervisors in the second half of 2027.
In April 2026, ESMA’s mandate was expanded, giving the authority direct supervisory powers over CASPs and large cross-border market participants.

It takes an average of 4.8 years from finalizing investment to starting construction of a data center project, and an additional 2.6 years from construction start to becoming operational. Servers usually cannot be installed until after the building structure and racks are completed. For trade partners such as Taiwan (China), South Korea, and Mexico who rely on US data center supply chain demand, the inertia in construction timelines provides at least a one- to two-year buffer for future exports.

Federal Reserve Major Debate: When Should the Tenure of “Number Three” Williams End?
The main point of contention is whether Williams should step down in June 2028, upon completing a full 10-year term, or in June 2027, when he reaches the mandatory retirement age of 65. Analysts point out that the Federal Reserve Board holds ultimate discretion; if he leaves early, Fed Chair Waller would be able to assert greater control over the appointment to this critical position. However, forcing Williams to shorten his term could easily be interpreted as political manipulation. Williams himself is expected to serve until June 2028.
