Good point, Bonnie.
Another problem with this proposal is its link with the HMDA/Reg C proposal, where the Fed wants reporting on whether a HMDA application is covered by HOEPA. Since so many activists equate HOEPA-loans to predatory loans, I think bank reputation risk is involved.
Also, while I'm not certain of this, I've seen other bankers assert that privacy issues are at stake with the HOEPA and HMDA proposals: That in rural areas or small towns, where there's not much lending activity, you'll be able to figure out, via matching HMDA LAR data with courthouse records, who the HOEPA loan went to and what the person's APR is.
