New York and EU watchdogs open a shared supervision channel for stablecoins

The European Banking Authority and the New York State Department of Financial Services have signed a memorandum of understanding to coordinate oversight of cross-border stablecoin activity, adding a practical supervisory layer to a market that is increasingly global in issuance, distribution and payments use. Reported by Cointelegraph, the agreement is designed to let regulators on both sides of the Atlantic share information and align their view of risks as stablecoin activity grows under separate but increasingly important legal regimes. The development matters because it moves beyond headline legislation and into the mechanics of how supervisors will actually monitor a market that can span multiple jurisdictions at once.

According to the EBA, the arrangement forms part of its duties under the European Union’s Markets in Crypto-Assets regulation, or MiCA. The memorandum sets out principles and procedures for exchanging information and coordinating supervisory activity tied to stablecoins, including work on market trends and emerging risks. That language is important. It suggests the regulators are not limiting cooperation to one-off enforcement issues or isolated investigations. Instead, they are building a standing channel for routine supervision in a segment where market structure, reserves, issuance and redemption patterns can all have cross-border implications.

New York’s regulator described the agreement in similarly operational terms. NYDFS said the memorandum would enhance supervision of entities engaged in stablecoin activities, help identify market trends and risks, and promote the integrity of the stablecoin market. Cointelegraph reported that the information to be shared includes the stablecoins that have been issued, total volume in circulation, the number of holders, the results of internal and external audits, and the regulatory standing of specific products and services. That list reaches into the core data points that shape confidence in a stablecoin market: who issued the token, how large it is, how it is being reviewed, and whether regulators see concerns building around a specific product or operator.

The memorandum also creates a framework for coordination during crises or emergencies. That detail may prove as important as the day-to-day information exchange. Stablecoins promise always-on settlement, but they also concentrate attention on reserve quality, redemption confidence and operational resilience when markets are stressed. A formal crisis-coordination channel gives both regulators a way to respond faster if a supervised entity with cross-border exposure runs into trouble. At the same time, Cointelegraph noted that the agreement is scoped to supervised entities’ stablecoin-related activities rather than every business line a company may operate. In other words, the regulators are targeting the part of the stack that matters most for stablecoin oversight without claiming blanket authority over unrelated activity.

The backdrop is a market that has kept attracting institutional attention even as its regulatory perimeter becomes more defined. Cointelegraph said banks and major financial institutions in both the United States and Europe have been testing stablecoins for payments. It also cited DefiLlama data showing the global stablecoin market above $319 billion as of Wednesday. In that market, dollar-linked tokens still dominate, with Tether’s USDT and Circle’s USDC identified as the two largest by market capitalization. The timing is also notable: US stablecoin legislation was signed into law in July, while MiCA came into effect toward the end of 2024. With both jurisdictions now operating inside clearer rulebooks, supervisors appear ready to focus less on whether oversight should exist and more on how it should function across borders.

For the sector, the message is that regulation is becoming part of the infrastructure story. Stablecoins have long been sold on speed, programmability and round-the-clock transferability, but larger-scale adoption depends just as much on credible oversight and consistent supervisory signals. The EBA-NYDFS agreement does not create a single transatlantic rulebook, and it does not erase the differences between EU and US policy. What it does do is reduce the gap between parallel regimes by creating a formal process for information sharing and coordinated supervision. As stablecoins move deeper into payments and treasury workflows, that kind of operational linkage may become just as important as the tokens themselves.
