The 10-year Treasury yield (DGS10) rose 3 basis points to 5.00% on September 15, 2026, the session's largest move, while the 2-year yield (DGS2) added 2 basis points to 4.67%.

This week's Treasury readings fall in the middle of the Federal Reserve's scheduled September 15-16, 2026 policy meeting, according to the Fed's official FOMC meeting calendar; the September 15 observation lands on the meeting's opening day, with the post-meeting statement and press conference following on September 16, and the next meeting scheduled for October 27-28, 2026. Separately, the Bureau of Labor Statistics' Consumer Price Index for August 2026, released September 11, 2026, showed the all-items index up 3.4% from a year earlier, matching the prior month's pace (data retrieved from bls.gov September 16, 2026; BLS does not vouch for analysis performed with the data after retrieval).

The 10-year yield (DGS10) moved from 4.97% on September 14 to 5.00% on September 15, up 3 basis points, while the 2-year yield (DGS2) moved from 4.65% to 4.67% over the same span, up 2 basis points, both per the Federal Reserve's H.15 release. Mortgage rates have no new reading this session: the 30-year and 15-year averages stand as reported for the week ending September 10, 2026, the most recent Freddie Mac PMMS survey, so those figures were observed before this brief's September 15 series date; the next PMMS release is due Thursday, September 17, 2026. Actual rates offered to individual borrowers vary by credit profile, loan term, and lender, so these national averages should not be read as a quote for any specific loan.

The gap between the 10-year and 2-year yields (the dgs10-dgs2 spread) widened by 1 basis point to 0.33 percentage points as of September 15, 2026. No confirmed source in this brief specifically addresses what drove this week's spread move; the spread is simply the arithmetic difference between the separately sourced DGS10 and DGS2 readings above, and no Green-lane primary source speaks to the shape of the yield curve on its own, so that background is left unconfirmed rather than presented as a cause.

What to watch next: Watch for the FOMC's post-meeting statement and press conference on September 16, 2026, the next Freddie Mac PMMS mortgage-rate release on Thursday, September 17, 2026, and the next scheduled FOMC meeting on October 27-28, 2026.
