10-Year Treasury Yield at 4.95%, 5-Year at 4.75% on Sept. 10

The market yield on U.S. Treasury securities at 10-year constant maturity was 4.95% on September 10, 2026, according to FRED.

The market yield on U.S. Treasury securities at 5-year constant maturity was 4.75% on the same trading date, per FRED. Taken together, the two prints imply a 5s10s spread of 20 basis points, with the longer tenor yielding more than the intermediate tenor.

FRED listed September 14, 2026 as the next release date for the daily 10-year series after its September 11, 2026 update. The dating defines the vintage of the observations. It does not revise the September 10 levels themselves.

The broader context here is what constant maturity means for professional use. The series is a par curve reading, interpolated to fixed tenors, not a transaction price for a single CUSIP. That construction is why portfolio managers, risk officers and corporate treasurers reference it for benchmarking and attribution. It standardizes tenor. It allows clean tenor-to-tenor comparison across dates.

In my view, level and slope should be read separately. The level sets the discount anchor for long duration cash flows. Small moves at these tenors translate into material present value change because duration is high and convexity builds with maturity. The slope isolates compensation between the belly and the long end. A positive 5s10s spread indicates additional yield for extending from five to ten years. That compensation bundles expectations for short rate paths, term premium, supply absorption across tenors, and convexity demand. No single print disentangles those drivers.

Looking at what this means for books and balance sheets, the distinction matters. Rate hedgers calibrate DV01 by tenor bucket rather than by headline yield alone. Liability driven portfolios map long dated obligations against the long end anchor. Issuers weigh tenor selection against all in funding cost and refinancing risk. Mortgage and structured product desks translate intermediate and long end moves into prepayment and extension assumptions through their own models. The September 10 prints give each of those functions a common mark. They do not dictate positioning.

Looking at what this means for data discipline, process matters more than narrative. Daily constant maturity data are point in time marks subject to release lag. Intraday price action can differ from the fixing. Revision methodology, holiday calendars and publication timing all affect vintage control. For that reason, the September 14 release date functions as a version marker. It tells users when to refresh models and attribution, not how to interpret direction. One observation establishes level. It does not establish momentum. Trend requires a sequence.
