The gains held. Rate sheets closed at 6.64% — 6 basis points better than the open — with the 10-year near 4.55% and UMBS 5.0 holding its 97-15 level into the close.

After two straight sessions where the question was whether a bond rally would survive to the close, today it did. And that matters more than the 6 basis points. Tuesday's CPI-driven move faded almost entirely by the bell — the rally showed up in the morning and gave most of it back by the afternoon. Today was built differently. A second soft inflation print, this time on the producer side, gave the move a second leg to stand on, and the bond market didn't need to reverse it. UMBS 5.0 opened at 97-15 and closed at 97-15. The 10-year that was testing the top of its summer range all season spent the whole day on the low side of 4.56% and stayed there. When a rally holds through the close instead of fading, that's the market putting weight behind the read rather than reacting to a single number.

For borrowers, the close at 6.64% is the first rate sheet in a week built on genuinely improved data rather than a bounce that unwound. The two consecutive prints — consumer and producer prices both below forecast — took the July Fed hike risk that had been priced into the curve and pulled a chunk of it back out. That's the mechanism behind the move. Retail sales is the next test: a soft print there, stacked on this week's inflation data, is what would give the 10-year a real shot at a sustained break below the 4.56% ceiling it's failed to clear all summer. For now, the read is simpler than it's been in a while — the gains came, and this time they stayed.
