We present a rigorous derivation of the orbital magnetization formula for interacting electrons within the self-consistent Hartree-Fock approximation. Our results are expressed entirely in terms of the self-consistent wavefunctions and the Hartree-Fock energy spectrum at zero magnetic field. We test the formula on a two-band interacting Rashba model, finding an agreement with calculations performed at small but non-zero external magnetic field. Our method also allows us to also derive formulas for the orbital magnetic susceptibility.
