  We show that the CKM matrix can be the source of CP violation for electroweak
baryogenesis if Yukawa couplings vary at the same time as the Higgs acquires
its vacuum expectation value. This offers new avenues for explaining the baryon
asymmetry of the universe. These ideas apply if the mechanism explaining the
flavour structure of the Standard Model is connected to electroweak symmetry
breaking. We compute the resulting baryon asymmetry for various low-scale
flavour models and different configurations of the Yukawa coupling variation
across the bubble wall, and show that it can naturally be of the right order.
