William Mason

Director General, Guernsey Financial Services Commission

William Mason is the Director General of the Guernsey Financial Services Commission. He served on the Executive Committee of the International Association of Insurance Supervisors between 2014 and 2022 where he chaired both the Audit and Risk Committee and the Standards Assessment Working Group, establishing IAIS’s regulatory assessment programme. He has a strong interest in Supervisory Technology and Green Finance. Under his leadership the Guernsey Financial Services Commission has developed:

• the Guernsey Green Fund framework (2018) and the Natural Capital Fund framework (2022), both possibly global firsts in environmental finance;

• bought into force environmentally sensitive green capital rules for life insurers possibly another world first for insurance regulation; and

• made moves, including planting 53,000 trees in 2022 in an ecologically advantageous fashion, towards becoming a net zero regulator.

In his spare time he maintains an ancient woodland, designated a Site of Special Scientific interest on account of its biodiversity.
