CME Fines Drop to $330,000 for Disruptive Practices in 2025

CME Group imposed the second-lowest aggregate monetary penalties since 2018 last year, even as disciplinary activity held steady at 127 notices, according to Cornerstone Research's report Trends in CME Group Disciplinary Notices: 2018–2025.

The headline shift sits in the fine totals. Penalties tied to Disruptive Practices Prohibited — historically the most frequently cited violation category — fell from $1.58 million in 2024 to $330,000 in 2025. That category appeared in only seven notices in 2025, down from its customary top ranking. Providing and Keeping Records took its place, cited in 31 notices.

The aggregate numbers frame the trend. Across eight years, CME Group issued 962 unique disciplinary notices and imposed more than $81 million in monetary penalties, split into roughly $59 million in fines, $12 million in disgorgement and $10 million in restitution. Notice volume declined 55% from 2019 through 2022, rose 80% in 2023, and has since flattened: 120 notices in 2024, 127 in 2025.

What changed in the composition of enforcement?

Nicole Moran, report coauthor and vice president at Cornerstone Research, said: "While the overall number of disciplinary notices changed little in 2025, the composition of enforcement activity shifted considerably. The findings suggest that while enforcement activity remained robust, the types of violations drawing scrutiny changed. Disruptive Practices Prohibited, historically the most frequently cited violation category, appeared in only seven notices in 2025, while Providing and Keeping Records was cited in 31 notices."

For compliance desks, that rotation matters. A collapse in disruptive-practices fines does not signal lighter exchange scrutiny; it signals the scrutiny moved to books-and-records and supervision cases. Four categories accounted for about half of all fines in 2025: Providing and Keeping Records, Member Coordination, Position or Margin Limit Violations, and Failure to Supervise Employees.

How severe were the individual penalties?

Fines remained near-universal: 125 of the 127 notices carried one. But the median nonzero fine fell to $25,000, against an annual average of $40,000 between 2018 and 2024. Median nonzero restitution dropped further in relative terms — $16,007 versus an annual average of $98,969 over the prior seven years.

Laurent Samuel, report coauthor and principal at Cornerstone Research, said: "While we saw a lower level of penalties in 2025, we also saw broad enforcement activity, with nearly half of notices citing multiple rules. At the same time, fines were concentrated in certain areas, with four categories alone accounting for about half of all fines."

The breadth cuts both ways. Multiple-rule citations per notice mean a single exchange inquiry can expose firms to stacked counts, even when the median dollar figure per case shrinks.

Which products drew the most notices?

Financial products and energy derivatives over-indexed. Financial products appeared in 43 notices in 2025, above the 2018–2024 annual average of 37. Energy derivatives appeared in 36 notices, well above their annual average of 24. Agricultural and metals products both came in below their historical averages.

Timing also shifted. Sixty percent of 2025 notices were issued in the second half of the year, continuing a pattern from 2024 and returning to the back-heavy distribution last seen from 2018 through 2020 — a scheduling quirk that concentrates year-end remediation and reporting work for member firms.

One caveat: the report counts notices and penalty totals, not the underlying conduct. Lower aggregate dollars in 2025 could reflect fewer egregious cases, faster settlements or a genuine change in violation mix — the data does not distinguish among them. What the record does show is that enforcement breadth held while penalty size compressed, and that recordkeeping and supervision categories are where the exchange is now spending its enforcement capital. Whether the disruptive-practices decline persists into 2026 will test whether 2025 was a rotation or a floor.
