These are FHA loans so they are bound to have high(er) defaults or late payments than conventional loans.
Delinquencies do not look very high from a historical perspective. Yes, they are high compared to the post-covid period. I would imagine this jump was expected with the rise in rates. But again - seeing the historical trend - its not really high.
