The 30-year Treasury yield closed on Friday at 5.49 per cent. That is the highest close since the Treasury brought the 30-year bond back in February 2006, after four years without issuing it.
It was not a quiet week for the rest of the curve either. The ten-year yield, which first closed at 5 per cent on 16 September, began last week at 4.96 per cent and finished it at 5.17. On Thursday it closed at 5.18, a level it had not reached since 6 July 2007.
Twenty-one basis points in three sessions is a large move for the benchmark that prices American mortgages and corporate debt. The shape of it is more informative than the size.
The long end moved, the short end followed
The two-year yield, the maturity most closely tied to where traders think the Federal Reserve is going, rose too, from 4.71 per cent on Tuesday to 4.81 per cent on Friday, having touched 4.87 per cent on Thursday, its highest close since June 2024. But it rose by roughly half as much as the ten-year, and the gap between the two widened from 25 basis points to 36.
A move led by the short end says the market expects the Fed to do more. A move led by the long end says something slower and harder to reverse: that investors want more compensation for holding money for a decade or three, because they are less confident about what inflation will be over that period. A week ago the two-year would not budge while stocks rallied on oil. Last week the long end did the moving.
Households got there first
The University of Michigan's final September survey of consumers asked households the same question in plainer terms and came back with the same answer.
Americans now expect prices to rise 4.6 per cent over the next year, up from 4.0 per cent in August. That is the highest reading since June, and it compares with 3.4 per cent in February, before the war with Iran began. Expectations for the next five to ten years, the figure the Fed watches most closely for signs that inflation is becoming entrenched, rose to 3.4 per cent after three months at 3.3. The survey's own commentary notes that both numbers are above their entire range for 2024.
The headline index of consumer sentiment fell to 48.1 from 51.7 in August, 12.7 per cent lower than a year ago. The index of expectations fell further and faster, down 10.1 per cent in a month to 46.3.
Joanne Hsu, the survey's director, gave the reason in her commentary: the short-run outlook for business "plunged amid renewed worries that elevated fuel prices and re-escalating trade disputes could pass through to the economy as a whole."
The partisan filter has stopped filtering
For most of the past decade the Michigan survey has been read with a correction applied: supporters of the party in the White House report feeling better, supporters of the other party worse, and the headline sits somewhere between. That correction is doing less work this autumn.
Hsu wrote that interviews "reveal broad agreement across the political spectrum that the outlook for the economy has weakened since the beginning of the year." Sentiment among Republicans is now 20 per cent lower than in January. Among Democrats it is 13 per cent lower. The steeper fall is among the President's own supporters.
When a reading moves in the same direction on both sides of that divide, it is harder to dismiss as politics and easier to read as prices. The survey attributes the change to fuel costs and trade. The bond market, pricing the same risks with money rather than opinions, moved the same way in the same month.
What this week has to answer
Monday began with Brent back above $107 after President Trump rejected Iran's offer to reopen the Strait of Hormuz, which is the fuel-price worry in its most direct form. Treasury had not published Monday's yields when this was written.
The week's data will test whether the long end has moved too far. Job openings are due on Tuesday, and the September employment report is scheduled for Friday. A weak labour market would argue for lower short rates; it would do much less for a 30-year yield that is being set by what investors, and households, think inflation will be in 2030.
Michigan's preliminary October reading is due on 9 October. It will be the first to show how households took Saturday's rejection.
All Treasury yields are from the US Treasury's daily par yield curve rates for 2026, read directly on the morning of 28 September; the latest published date was Friday 25 September. The comparisons with 6 July 2007 and 10 June 2024 are from the Federal Reserve Bank of St Louis's constant-maturity series DGS10 and DGS2 on FRED, which ran to 24 September when read. The 30-year comparison applies Friday's Treasury close to FRED's DGS30 series from 9 February 2006, when the Treasury resumed issuing the bond. DGS30 carries values for 2002 to 2006, including 5.49 per cent on 28 June 2004, but no 30-year bond was issued in those years, so those values are not comparable. All survey figures and the characterisation of the survey's findings are from the University of Michigan Surveys of Consumers' final results for September 2026 and the accompanying commentary by its director, Joanne Hsu, published on sca.isr.umich.edu. Monday's Treasury yields had not been published when this article was written. Brent's move on Monday is as reported by Al Jazeera. Accurate to 9.50am ET on Monday 28 September 2026.
