ZURICH (Reuters) - The Swiss National Bank posted an annual loss of 3.2 billion Swiss francs ($3.62 billion) for 2023, the central bank said on Monday, as losses caused by the appreciation of the Swiss francs weighed.

The 2023 result, which confirmed the SNB's provisional forecast in January, was an improvement from the record 132.5 billion franc loss the central bank posted in 2022.
