Antoine Martin will replace Andrea Maechler, who stepped down from the SNB at the end of June to become deputy general manager at the Bank for International Settlements.

Martin will join Chairman Thomas Jordan and Vice Chairman Martin Schlegel on the governing board, the body which sets the SNB's monetary policy.

Hailing from the french-speaking part of Switzerland, Martin joins the SNB from the Federal Reserve Bank of New York where he currently works as financial research advisor on financial stability policy research.

"Thanks to his many years of Federal Reserve Bank work, Antoine Martin is familiar with the concerns of a central bank and has sound, practical experience in the field of monetary policy," the Swiss Federal Council said in a statement.

Thomas Moser will hold the position on an interim basis until Martin's official start date of Jan. 1, 2024.
