SARON Fixing

SARON fixing is the publication process that turns repo-market observations into the official Swiss Average Rate Overnight for a given business day.

Definition

SARON fixing is the publication process that turns repo-market observations into the official Swiss Average Rate Overnight for a given business day.

Mechanism

The rate originates in the secured CHF money market rather than an unsecured bank panel. Daily observations are aggregated or compounded according to the relevant SIX methodology and contract convention.

Market relevance

Changes in SARON transmit quickly into floating-rate funding, derivatives and SARON-linked mortgages. The spread to the SNB policy rate also reveals conditions in secured franc liquidity.

What to monitor

Watch the SNB policy rate, repo-market conditions, fixing and compounding conventions, reset dates and the contractual margin charged above the reference rate.
