Relatively Sharp Losses, but Nothing Special in The Bigger Picture Bonds began the day modestly stronger, and that was their first mistake.  Starting around 10am, the gains began evaporating following comments from Fed's Kashkari (who needs to see "many" more months of good inflation before considering a cut) and a big pop in consumer confidence data.  In the next 3 hours, both the 2yr and 5yr Treasury auction would add to the pressure.  MBS were only down a quarter point on the day, which is an unremarkable move for the first day back after a 3 day weekend, but in contrast to the low volatility gains in the first 2 hours of the day, it feels subjectively abrupt.  Mortgage lenders concur, based on the number of reprices (and 2nd reprices).
