Graham is a recognised expert in banking and finance law, specialising in particular in structured finance and debt capital markets along with debt trading and financial retail product documentation. He was responsible for the earliest securitisation transactions involving Scottish assets and developed (with co-partner Hamish Patrick) the structures since generally used to securitise assets in Scotland. More recently he has pioneered the development of Islamic finance within Scotland on which he is now considered the country's leading expert, having structured and documented the first (and so far only) Islamic mortgage products operating under Scots law and the first fully Sharia-compliant commercial real estate financing in Scotland. He is a member of the Advisory Board of the Islamic Finance Council UK.
The latest edition of Chambers and Partners Guide conferred on Graham the accolade of "Senior Statesman" in banking and finance law in Scotland, the only lawyer so recognised.
