We compute the one-loop mixing of bosonic and two-fermion interactions into two-fermion operators in the dimension-eight Standard Model Effective Field Theory (SMEFT). Together with the results in refs. [ SciPost Phys. 11 (2021) 065, Eur. Phys. J. Plus 137 (2022) 973, JHEP 12 (2024) 214, JHEP 08 (2026) 225], this leaves only the mixing of four-fermion operators into two-fermion ones as the remaining piece to complete the SMEFT renormalization program at this order.
