Goldman Sachs Group Inc is shaking up the leadership ranks at its global financing group after the Wall Street bank merged its investment banking and trading business into a single unit.

Michael Marsh will become head of the Europe, Middle East and Africa financing group, according to an internal memo seen by Reuters. He joined the bank in 2006.

The internal memo, dated March 22, also named John Greenwood as head of the Latin America financing group, in addition to his current role as head of project, infrastructure and principal finance and his leadership responsibilities for the sustainable banking group.

Goldman in October said it would reorganize its business into three units and scale back ambitions for its consumer bank.

Dominic Ashcroft will become head of EMEA Leveraged Finance, according to another memo, dated March 27, seen by Reuters. He is currently the co-head of EMEA Credit Finance Capital Markets. (Reporting by Jaiveer Shekhawat in Bengaluru; Editing by Shilpi Majumdar)
