BNP Paribas's new New York-based head of structured product gave up on banking eight years ago. : It’s happened again: someone who left banking years ago, first for a hedge fund and then for a fintech firm, has reappeared in a bank. Yang began his career as a structured credit professional at Credit Suisse in 2000. He worked for Deutsche Bank and Barclays; latterly as a director of mortgage backed products on the principal trading desk, before leaving for a hedge fund in 2009. The new role at BNP Paribas marks Yang’s move back into banking after nine years out.
