Plain-English explanation
Mortgage rates track long-term bond yields, especially 10-year Treasury and MBS. An inverted curve (short rates above long) often precedes economic slowdowns.
Why it matters
Understanding the curve helps borrowers time locks and refinances in shifting markets.

- Rate lock confirmation
- Secondary market disclosures
A real-world example
When 10-year Treasury yields rise 0.25%, mortgage rates typically rise a similar amount within days.
Educational and illustrative only
A common misunderstanding
The yield curve doesn't directly set mortgage rates — it's a broader bond-market indicator that can influence, but not fully determine, mortgage pricing trends.
