SARON - the new Swiss franc benchmark

SIX is the Benchmark Administrator of SARON. The SARON represents the overnight interest rate of the secured funding market for Swiss franc (CHF). It is based on transactions and quotes posted in the Swiss repo market, a pivotal part of the Swiss Value Chain.

Internationally, there is a consensus that financial benchmarks need to be resilient and reliable. Repo markets, in their role as the backbone of the financial industry and central bank activity, are the obvious choice. They are liquid, highly regulated and of high integrity. The National Working Group on Swiss franc reference rate, which leads efforts to reform benchmark interest rates, has recommended SARON as the alternative for CHF LIBOR.
