US, UK Regulators Test Response to CCP Crisis Scenario

Senior officials from five major US and UK financial regulators met on Sept. 3, 2026, to conduct a tabletop exercise examining how authorities would respond if a major central counterparty faced financial distress, according to a joint readout of the meeting.

The exercise brought together principals from the Securities and Exchange Commission, the Federal Deposit Insurance Corporation, the Commodity Futures Trading Commission, the Federal Reserve Board, and the Bank of England. The gathering focused on coordination issues that would arise in the resolution of a central counterparty, or CCP, operating across both jurisdictions, according to the joint statement released by the agencies.

Central counterparties sit at the core of global derivatives and securities markets, acting as intermediaries between buyers and sellers to guarantee trades even if one party defaults. Because a handful of these clearinghouses handle enormous volumes of transactions spanning multiple countries, regulators have long treated their potential failure as a top-tier systemic risk concern. The joint readout indicated that the September session was designed to test communication channels, information sharing protocols, and decision-making processes that would be needed among US and UK authorities in a real crisis scenario.

While the release did not detail specific findings or identify any particular clearinghouse involved in the simulation, it characterized the meeting as part of an ongoing effort by regulators on both sides of the Atlantic to strengthen cross-border cooperation on resolution planning. Officials have periodically held similar exercises in past years as part of broader efforts to close gaps exposed by the 2008 financial crisis, when the absence of coordinated cross-border resolution tools contributed to market turmoil.

The timing of the exercise reflects growing regulatory attention worldwide to the concentration of risk within a small number of systemically important clearinghouses. Since the global financial crisis, regulators have pushed more derivatives trading through central clearing to reduce counterparty risk in bilateral markets. That shift has made CCPs themselves larger and more interconnected, prompting watchdogs in the US, UK, European Union, and elsewhere to develop specific resolution regimes for these entities, distinct from the frameworks used for banks.

Industry participants, including major banks, asset managers, and clearing members, have watched this regulatory work closely because any disruption at a major CCP could ripple quickly through interconnected markets for futures, swaps, repos, and securities. Cross-border coordination is considered especially important because many clearinghouses serve members and clients located in multiple countries, meaning a resolution action taken by one national authority could have immediate consequences for market participants and financial stability in another jurisdiction. Tabletop exercises like the one held in September are widely viewed by regulators as a low-cost way to identify gaps in legal authority, information sharing, and operational readiness before an actual crisis unfolds.

The joint readout did not indicate whether additional exercises or follow-up meetings between the agencies are planned, nor did it specify what changes, if any, might result from the September session. Regulatory tabletop exercises of this kind typically inform internal contingency planning and may lead to updates in memoranda of understanding or supervisory guidance rather than immediate public rule changes.

The five agencies did not release further specifics on the substance of the discussions held during the meeting.

According to a joint press release from the Securities and Exchange Commission, the exercise underscores the continued priority regulators place on preparing for potential stress at systemically important financial market infrastructure.
