U.S. Treasury yields ended September at levels that keep borrowing costs high around the world. The Treasury Department’s daily par yield curve shows the 10-year note at 5.26% on 29 September 2026, the 30-year at 5.59% and the 2-year at 4.89%, based on Treasury’s published rates. The day before, the 10-year closed at 5.24% and the 30-year at 5.56%. These Treasury yields matter because they act as a benchmark for dollar borrowing.

The numbers on the last trading days
According to Treasury’s table, the 2-year yield slipped from 4.92% on 28 September to 4.89% on 29 September, while the 10-year rose from 5.24% to 5.26% and the 30-year from 5.56% to 5.59%. Long-dated yields edged up as short-dated yields edged down, so the gap between the 2-year and 10-year widened slightly to 37 basis points.
Weekly market data compiled by TradingKey, a market-analysis site, says the 10-year yield touched 5.225% during the week of 21-27 September before closing near 5.17%, and that Brent crude fell below $98 a barrel. Treat those as a secondary-source snapshot; the Treasury table above is the primary record. For the stock-market side of the same week, see our note on S&P 500 record highs alongside rising yields.
The Fed’s September hike
The backdrop is the Federal Reserve’s 16 September decision. The Federal Open Market Committee voted 12-0 to raise its target range by a quarter point to 3.75%-4.00%. In its policy statement, the Committee said inflation “remains elevated” and that the move would support a timelier return to its 2 percent goal, while describing economic activity as expanding at a solid pace. CNBC had reported on 14 September that the 10-year yield hit 5% before reversing as traders awaited the meeting, so yields have moved higher since.
How it reaches borrowers abroad
Consider a hypothetical Brazilian founder who raised a dollar-denominated loan last year. This is an illustration, not a reported case. If that loan resets against a dollar benchmark, higher U.S. rates raise the interest bill, and converting reais into dollars to repay it adds currency risk on top. The same logic applies to governments and companies that issue dollar bonds, and to exporters whose customers finance purchases in dollars. The effect varies by contract, so anyone exposed should read their own loan terms rather than rely on the headline yield.
Data that could move yields next
The coming week is crowded with releases. Our week-ahead economic calendar sets out the scheduled reports, and our coverage of Micron’s results shows how technology earnings are feeding the equity side. Surprises in jobs or inflation data are the usual catalysts for sharp moves in the 10-year yield.
Quick answers
What was the 10-year Treasury yield on 29 September 2026?
The U.S. Treasury’s daily par yield curve shows 5.26%, up from 5.24% on 28 September. The 2-year was 4.89% and the 30-year 5.59%.
What did the Federal Reserve do on 16 September?
The FOMC voted 12-0 to raise the federal funds target range by 0.25 percentage points to 3.75%-4.00%, according to its statement.
Why do Treasury yields matter outside the United States?
Dollar yields are a benchmark for global borrowing. When they rise, dollar-denominated loans and bonds generally cost more to issue or refinance, including for companies and governments outside the U.S.
Is a yield curve with 10-year above 2-year inverted?
No. On 29 September the 10-year yield (5.26%) was above the 2-year yield (4.89%), which is a normal upward-sloping shape.
Where can I check the latest yields myself?
The U.S. Treasury publishes the daily par yield curve rates on its website, and the Federal Reserve publishes the H.15 selected interest rates release.
