OANDA risk responsibilities change
Mark Chesterman has left OANDA, where he spent seven years as Chief Risk Officer. He announced his departure in a LinkedIn post published Tuesday, 20 October 2026. His exit removes a senior figure whose responsibilities had spanned risk and trading operations.
His work also included mergers and acquisitions and board governance. Chesterman's profile lists a separate Head of Trading role at OANDA, held for two years and nine months. He also referred to global leadership duties during the growth of artificial intelligence.
Recent appointments reshaped OANDA leadership
OANDA has seen other senior changes. In June, Lucian Lauerman became Chief Executive Officer of OANDA Europe Limited. That followed FTMO founders Otakar Šuffner and Marek Vašíček taking on co-CEO roles at OANDA after discussions with Gavin Bambury, who stepped down as CEO.
IG roles spanned trading and growth
Before OANDA, Chesterman spent ten months as Chief Operating Officer at prime-of-prime broker Stater Global Markets. His preceding stint at IG lasted more than 14 years, Finance Magnates reported. His positions there ranged from dealing and futures and FX to institutional operations and business development.
At IG Institutional, Chesterman was Chief Operating Officer for eleven months. He worked on the unit's operating processes, the onboarding of clients and its credit risk policies. He later spent two years and two months as Global Business Development Officer, with a remit covering strategy, product development, marketing and revenue growth for IG's institutional business and MetaTrader 4 platform.
Earlier, Chesterman led Futures and FX at IG for three years and ten months, covering trading strategy, monetisation of client flow and product development. His product remit covered interest rates and commodities as well as index derivatives and foreign exchange. His first IG position was Dealer for four years and seven months, followed by three years as Chief FX Dealer.
The integration question
For OANDA's trading and risk teams, the public information does not identify who will take over Chesterman's responsibilities. Operators will need to establish where ownership now sits for risk limits, trading operations, board reporting and any work linked to mergers and acquisitions.
The company has not specified whether those duties will be reassigned or whether the departure will lead to changes in systems, controls or reporting lines. Teams should confirm who approves risk-policy changes, who owns trading oversight and how escalations reach the relevant leadership group.
It is also worth checking whether responsibility for institutional onboarding and credit risk policies sits with the same teams as before. The source does not say whether Chesterman's departure changes those processes, but clear ownership will matter wherever his former remit crossed trading, risk and governance.
