 // . //  Notre Équipe //  Arthur Grammaticopoulos

Arthur is a principal at Oliver Wyman, based in the Paris office. He has more than 12 years of experience in financial services and advises regional and global banking players on strategy, MA, and risk management.

Arthur first set foot on a trading floor at the age of 19 when he embarked on an internship in a French investment bank, working three days a week in parallel with his Master’s classes.

The experience helped him grasp the relevance of banking on the economy, and how financial institutions deliver an essential service to communities and businesses. In 2010 he started his career within the General Inspection arm of Société Générale, where he participated in and led audit projects focusing on credit, operational, and market risks. He joined Oliver Wyman in 2017.

Traveling helps put things in perspective when advising banking institutions. I’ve discovered some of the best-performing banks are to be found in Asia or the US

From launching digital products for his French clients to building a greenfield bank in Benelux, restructuring a business unit in China, designing a new regional organization for a network of Sub-Saharan banks, or providing risk management advisory to a South African institution, Arthur has extensive experience in transformation and building disruptive business models.

In his free time, Arthur enjoys playing the guitar and attending heavy metal gigs.
