Du Plessis, the global head of listed derivatives at TP ICAP-owned Liquidnet, is leaving the firm on July 1, a spokesperson confirmed, to become head of economics and business at Clayesmore School in Dorset at the end of August, relocating from the United States.

In a career stretching back to the LIFFE floor in 1992, du Plessis held derivatives roles at Lehman Brothers and Deutsche Bank before eight years at UBS where he was latterly global head of FX, rates and credit execution services.

He left the Swiss bank in March 2019 to join TP ICAP as a senior managing director in July that year, before moving to Liquidnet in March 2022 to spearhead the venue’s push into futures and options.

TP ICAP bought agency broker COEX Partners in 2017 and Liquidnet in March 2021, paving the way for the current derivatives expansion.

“The premise of this business has always been to try to utilise the unique heritage and technology capabilities of Liquidnet to solve workflow issues that still exist in the listed derivatives space,” du Plessis (pictured) told FOW in June last year.

Speaking as the firm published analysis in January, du Plessis said major exchanges faced a challenge maintaining the growth of derivatives trading seen over recent years.
