 tract: In this talk I will describe how the analytic structure of scatteri
 ng amplitudes impose non-trivial constraints on the standard model effecti
 ve field theory (SMEFT). For example\, in the bosonic sector\, I will expl
 ain how the bounds imply restrictions on the size of certain CP-odd operat
 ors by associated CP-even couplings. This result can be exploited to revea
 l a connection between constraints derived at colliders and limits on the 
 neutron electric dipole moment. Further\, I will demonstrate that in the f
 ermionic sector\, IR consistency requires that flavour violating operators
  are bounded by the flavour conserving variants. While most results will b
 e presented for the SMEFT at dimension 8\, I will also describe recent pro
 gress allowing a subset of the results to be lifted to dimension 6.
