Kenko Tokina announced new price increases on Tokina and Zeiss lenses in Japan (Kenko Tokina is a Zeiss distributor for Japan). My assumption is that similar price increases will be implemented also in other countries.
The list of Tokina lenses with a price increase can be found here and the Zeiss price increase is available here.
Leica also recently announced in the US:
Not an April Fools’ Day joke: Leica price increase coming to the US on April 1, 2022
Nikon will also have a price increase coming to Northern Europe on April 1st
