Episode notes
Size Matters But It's Not QE
- $200bn in planned GSE MBS purchases is large relative to annual organic supply but small versus past Fed QE operations.
- The move is not QE because the GSEs cannot create reserves and must likely issue debt to fund additional purchases.
Retained Earnings Can Fund Purchases, But Debt Likely Needed
- Fannie and Freddie hold about $180bn in retained earnings mostly in cash and repo, which could be converted into MBS purchases.
- They will probably still need to issue short-term debt if they fully execute $200bn and want operational cash buffers.
Current Coupons Will Be The Focus
- The GSEs will likely buy current-coupon UMBS (their own and each other's) to directly target mortgage rates.
- They may also buy Ginnie Mae MBS to help affordability for FHA borrowers if those lag.
