Do the SNCF fidelity "points monnaie" expire when switching status?

I am currently a member of the SNCF fidelity program and I am a "Grand Voyageur", a status that lets you collect points ("points monnaie") for every euro spent. Soon, it will be the anniversary of my membership so my status may change. In my case, as I did not collect enough "points statut", I will switch to the "Voyageur" status. This status does not have "points monnaie". Will I lose all of these "points monnaie" (if so I should try to redeem them) or are they independent from my status? I did not dig much in the help yet, the basic interface of my account does not mention any expiration date.
