Abstract:	We completely determine all varieties of monoids on whose free objects all fully invariant congruences or all fully invariant congruences contained in the least semilattice congruence permute. Along the way, we find several new monoid varieties with the distributive subvariety lattice (only a few examples of varieties with such a property are known so far). © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
