The thesis
Why this org is unusual
Global operating CEOs report directly to the group CEO, which is unusual for a diversified financial firm of StoneX’s scale.
The structure places regional and subsidiary CEOs—Asia Pacific and StoneX Financial Inc.—on the same level as functional leaders like the CFO and COO. This creates a flatter enterprise model with strong CEO span of control and faster escalation from operating units to the top.
The model emphasizes accountability at the regional and subsidiary level while maintaining centralized finance, risk, and operations oversight. Risk management remains highly centralized, with the CRO reporting directly to the CEO and interfacing closely with the board’s Risk Committee. Overall, the structure reflects StoneX’s history as an acquisitive, trading-oriented firm where operating units retain significant autonomy.
- Regional and subsidiary CEOs report directly to group CEO
- Centralized risk function with board-level oversight

Larger diversified peers like Raymond James or CME Group typically interpose divisional presidents or segment heads. StoneX’s approach results in …
