A major criticism of most primordial black hole (PBH) scenarios is the existence of important fine-tuning issues. I will explore a new way to address this problem, with a light stochastic spectator field during inflation, leading to the formation of stellar-mass PBHs. Such PBHs could constitute most of the dark matter and explain the LIGO/Virgo observations of compact binary coalescences. A natural candidate is the Brout-Englert-Higgs field, leading us to the investigate the possibility to form PBHs in the Standard Model. In parallel, the gravitational collapse of primordial inhomogeneities can provide the missing ingredients to achieve an efficient electroweak baryogengesis within the Standard Model, generically leading to similar abundances of baryons and dark matter in the form of PBHs. This completes the picture where PBHs provide a unified explanation to several key problems in cosmology.
