The Euro has experiencing a weakening against Swiss Franc since late 2019. Partly because of growing risk-off sentiment in the Euro area and the outbreak of Covid-19 pandemic which have caused the surge in demand for safe havens (Gold, Yen, Chf, and Usd).
With the likelihood of improvement in risk condition and the worry for Swiss National Bank that the overvalued Franc wont be good for the economy, it appears that the Franc might slightly weakened against Euro in the medium term.
