The daily 30-year fixed mortgage rate index slipped 0.05 percentage point to 6.70% after June CPI came in lower than expected, producing only a modest recovery from Tuesday's high.
Tuesday's 6.75% reading matched the May 19 peak and marked the highest level since July 29, 2025, leaving rates near the top of their recent range.
Lower inflation usually helps mortgage rates by supporting bond prices, but markets limited the move because July fuel-price gains could still lift inflation in the next report.
Fed Chair Warsh's congressional testimony had little market impact, underscoring that inflation data—not policy commentary—drove Wednesday's rate move.
