The price increase of 60 francs will probably have several reasons. But in my opinion/assumption, the main reason will probably be the corona virus.

As home office and leisure/quarantine have increased due to the coronavirus, the demand for electronic articles has also risen sharply. Because the demand for these items has increased so much, but the supply of electronic goods has remained about the same, there is a price explosion. Supply and demand mainly determine the price.

I have read in various newspapers that all online shops are literally overrun with orders because of the corona virus, so it is very likely that the price increase has something to do with it.

But it's a great motherboard that I've installed myself. Personally, it would be worth the extra 60 (total 140) to me.
