Treasury Yield Curve Analysis — September 11, 2026

The 30-year Treasury yield stands at 5.35 on Friday, September 11, 2026, up from 5.24 one week ago. The long bond has climbed steadily through the week, closing 11 basis points higher than last Friday's level. Yesterday the 30-year Treasury yield sat at 5.37, so today's close marks a slight pullback from the prior session. Even so, the week's overall move at the long end was firmly higher.

Rates rose across the entire maturity schedule compared with last week. The 10-year Treasury rate moved to 4.96 from 4.78, while the 2-year Treasury rate climbed to 4.63 from 4.37. Shorter maturities also advanced, with the 4-week bill at 3.93 versus 3.79 a week ago and the 1-year at 4.35 versus 4.13. The 20-year rose to 5.38 from 5.25, and the 5-year and 7-year each gained roughly 20 basis points on the week.

Over the past month, increases were largest in the middle of the curve. The 2-year Treasury rate is 35 basis points higher than the 4.28 recorded on July 31, and the 10-year Treasury rate is up 21 basis points from 4.75. The 30-year Treasury yield has risen more modestly, standing 8 basis points above its month-ago level of 5.27. At the front end, the 4-week bill is 15 basis points higher than a month ago, and the 20-year has added 10 basis points since late July.

The Treasury yield curve slopes upward from the 4-week bill through the 20-year, with one dip along the way: the 6-month rate at 4.12 sits below the 4-month rate at 4.15. At the long end, the 20-year at 5.38 is above the 30-year at 5.35, leaving that segment of the Treasury yield curve inverted by 3 basis points. A week ago the same pairing showed a smaller gap, with the 20-year at 5.25 against the 30-year at 5.24. Thirty days ago the 20-year at 5.28 also stood above the 30-year at 5.27, so the inversion at the long end has been present throughout the month and is slightly wider today than at either earlier point.
