We hear that the PennyMac fiasco was largely caused by Bill Pulte and the Trump Administration. Most people in the markets don't realize that the GSEs had already bought a ton of mortgage-backed securities (MBS) in Q4 of last year. This market manipulation tightened mortgage spreads 15-20bps and increased mortgage prepayment speeds without a corresponding offset from hedges in the Treasury market. This set up PennyMac and other mortgage lenders for a disaster.
