Overnight interest rates play a significant role in determining the yield curve. Going forward, the point of departure for Switzerland’s yield curve is SARON, an overnight reference rate based on data from the Swiss franc repo market. Repo transactions represent an important instrument for banks in their daily liquidity management activities. Repo transactions have become a key pillar of the money markets – and the Swiss National Bank (SNB) uses repo transactions as a means of implementing its monetary policy.
The reference rate SARON, which stands for Swiss Average Rate Overnight, represents the overnight interest rate of the secured money market for Swiss francs (CHF). It is based on transactions and quotes posted in the Swiss repo market, a pivotal part of the Swiss Value Chain. SIX is the Benchmark Administrator of SARON and is responsible for its calculation and publication. Further information on licensing, data access and usage can be found on the licensing page.
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.
