The G20 brings together the 19 leading advanced and emerging economies plus the European Union. They represent approximately 80% of global economic output and some two-thirds of the world's population. Although its decisions are not binding, the G20 plays a central role internationally as a global forum for economic, financial and monetary issues.

Switzerland participates, upon invitation, in the G20 Finance Track. This comprises meetings of G20 finance ministers and central bank governors, corresponding deputies' meetings and various working groups.

The member country holding the G20 presidency is responsible for issuing invitations to participate. To date, Switzerland has been invited by Russia (2013), China (2016), Germany (2017), Argentina (2018) and Japan (2019).

Participation in this economic policy forum is of great significance for Switzerland with its open economy and important financial centre. Swiss interests are jointly represented by the Federal Department of Finance and the SNB.
