Paul Chappell

Paul Chappell  – 29 June 1953 – 24 June 2018     

ACI UK Executive Committee/ACI FMA Director of Education /ACI FMA FX Committee

A long-standing and active participant of ACI’s Foreign Exchange Committee, in the past few years Paul had stepped up his involvement in ACI activities considerably, joining the ACI UK Executive Committee to support its local efforts and then, in 2017, becoming ACI’s first full time Director of Education.  In this role, he worked tirelessly to promote ACI’s services in support of the new Global Code and to continue ACI’s influence in guiding industry best practice.  Paul was especially engaged with ongoing industry debate around ‘last look’, chairing the ACI Working Group on the subject and bringing a voice of reason to this controversial topic. Paul was a stalwart of the foreign exchange market; both as a market practitioner and a committed proponent of industry best practice.

Paul was the epitome of an ‘industry veteran’, having enjoyed a long, illustrious and varied career in financial markets. He was, particularly, at the forefront of the modern foreign exchange industry, initially on the ‘sell side’ with roles at Chemical Bank, and for a long period, Bank of America, where in the late 80s and early 90s he was a major influence on the development, launch and take up of EBS (Electronic Broking Services).

An active and vociferous member of the original EBS consortium (representing Bank of America’s stakeholder interests) Paul’s commitment and support for the (then) market-changing EBS proposition, and his determination to ‘change dealer behaviour’ – starting on his own trading floor – contributed greatly to its early market adoption (and its great success).

Paul went on to create C-View, an FCA-regulated Investment Manager named – rather neatly – after his lovely holiday home, Sea View, in the Isle of Wight, where he enjoyed many happy vacations with his young family (and which he ‘shared’ on occasion with friends).  As Chief Investment Officer of C-View, Paul gained first hand insight into the ‘buy side’ experience of trading relationships  and more recently, the challenges of implementing mandates and directives like EMIR and MiFID.  He channelled this experience into providing consultancy to other market participants and regulators.

At a time in his life when he could have taken life much more easily – and with plans in place to enjoy his retirement with his wife Ann now his children were grown – he chose instead to embark on this new ‘career’, travelling extensively to spread the ACI word at industry conferences and events, meeting regulators and industry groups across the globe, and supporting ACI National Associations.

Paul was a devoted family man and committed Christian whose great pride in all of his family’s achievements were evident to everybody who met him.  He is a great loss to our industry and to so many of us personally.  We all miss him very much.
