Citi has appointed Peter Orszag as vice chairman of its global banking business.

Orszag was formerly the Director of the Office of Management and Budget (OMB) under President Barack Obama and is currently a distinguished visiting fellow at the Council on Foreign Relations.

Citi said Orszag will be a member of the Senior Strategic Advisory Group, which includes some of Citi’s most senior and effective bankers focused exclusively on client relationships.

Prior to his role in OMB — a cabinet-level position where he oversaw the administration’s budget policy, coordinated the implementation of major policy initiatives throughout the federal government and reviewed federal regulatory action — Orszag served as the director of the Congressional Budget Office (CBO), supervising the agency’s work in providing objective, nonpartisan, and timely analyses of economic and budgetary issues.

Prior to CBO, Orszag was the Joseph A Pechman senior fellow and deputy director of economic studies at the Brookings Institution. He also served as director of the Hamilton Project, director of the Retirement Security Project, and co-director of the Tax Policy Center.

During the Clinton administration, he was a special assistant to the President for economic policy and before that a staff economist and then senior advisor and senior economist at the President’s Council of Economic Advisers. He has also founded and subsequently sold an economics consulting firm.

Citi Institutional Clients Group CEO John Havens said peter brings a tremendous amount of knowledge as well as key private sector and government experience to global banking. His expertise in economic policy will complement Citi’s Investment Banking franchise around the world.
