The global head of debt capital markets at BNP Paribas has left after less than two years in the role, while the head of credit strategy in Societe Generale's award-winning cross-asset research team has also departed, according to people familiar with the matter.

Christopher Marks had spent roughly 15 years at BNP Paribas. His roles have included running public sector DCM, European corporate DCM, Emea DCM, and most recently global DCM, after the French bank decided in May 2012 to create a single global DCM platform as part of its efforts to pursue an originate-to-distribute model.
