The point being made here is that we actually do have the counterfactual available to us. Jumbo mortgages are not underwritten by the government, and they're exclusively private transactions between lender and borrower where the lender keeps the mortgage on the books and assumes all risk of default, interest rate changes, inflation, etc. And we know the market premium for this risk, because we can compare the difference in rates between a jumbo and conforming loan. It's about a half a percent.
