Considerably, too - this isn't a penny-ante increase to keep up with inflation. (More about it here and especially here.) In brief, to be eligible for a FIDE rating a player would first have to shell out 10 euros as a "license", then pay 30 euros for a yearly license or 500 euros to keep them in good standing the rest of his life. (Note: it's ambiguous, the way it's written in the material I've seen online, as to whether the 30 euros/year or 500 euros/lifetime fees would apply to everyone or only those who don't yet have a FIDE rating.)
FIDE also intends to considerably jack up the title fees - from 70 euros to 200 for the FM title, from 165 to 300 for the IM title and from 330 to 500 for the GM title. There are still other fees, too - but how many will pay them? Should this crazy measure pass, FIDE will discover that raising fees and rates doesn't automatically mean raising income.
It's a pity chess isn't run by professional management.
