Softer Inflation Cut October Hike Odds, but Long-Term Yields Rose to New Highs Anyway

Core inflation came in well below forecasts, and the bond market still sold off. Core PCE rose 0.2% in August against 0.3% expected. October hike odds fell to about 47%. But the ten-year closed near 5.30%, around its highest since 2007. The thirty-year ended near 5.63%, about 1 basis point below its 2002 high of 5.644%, while the two-year barely moved. The reasons: much of the inflation miss came from a change in how prices are measured, and the same release showed the economy grew faster in the spring than first reported. Stocks gave up early gains, and the S&P 500 finished down 0.25%. A thirty-year close above 5.644% would confirm the move. A close under 5.44% would undo it.

• Core PCE rose 0.2% in August and 3.0% from a year earlier, against forecasts of 0.3% and 3.3%; headline was 3.4% against about 3.7%. The revisions alone cut July's core rate from 3.3% to 3.0%, so most of the miss reflects the new method, not slower price growth.
• Second-quarter GDP was revised to 2.2% annualized from 1.5%, with consumer spending revised to 3.8% from 3.4%. A stronger economy than reported weakens the case that rate hikes are already slowing demand.
• The ten-year rose more than 4 basis points to 5.298% while the two-year was little changed at 4.895%. The gap between short and long yields widened for a third day, so the pressure is coming from investors' demand for more yield on long bonds, not from expected Fed moves.
• October hike odds fell to 47.1% on CME FedWatch, but only 10% of pricing has the Fed holding through year-end. The soft print moved the timing of the next hike, not whether it comes.
• The S&P 500 fell 0.25% to 7,651.54 and the Dow 0.86% to 50,906.05; the Nasdaq rose 0.24% to 26,861.06. The S&P 500 lost 0.5% in September but rose 2% for the quarter.

September 30, 2026 Close

Why it happened

This morning's read was mixed. It was right that a soft PCE print might not bring the thirty-year down. It was wrong that Williams's comments had brought relief: the ten-year closed at about 5.30%, above the 5.29% level the morning report said would end it.

• The inflation miss was mostly a revision. The Bureau of Economic Analysis changed how it measures prices for software, legal services and portfolio management, which lowered July's core rate by about 0.3 points. Bond investors marked the print down for that, and yields fell only briefly after 8:30 a.m.
• The same update raised growth. GDP revised to 2.2% from 1.5% says the economy was stronger in the spring than reported. ADP reported 90,000 private jobs in September against about 70,000 expected, the first pickup since May. Together, those two numbers outweighed the inflation miss.
• Oil kept its monthly gain. Brent rose 1.1% as US-Iran talks stayed stalled, closing a month up about 14%. That supports the inflation worry behind the long end, though the thirty-year rose on Tuesday when oil fell, so oil is a background factor rather than the cause.
• The pressure is global. Government bonds were set for their worst month in years on weaker public finances, heavy issuance and war-driven inflation risk. That points to the same supply and inflation premium Tuesday's report described, not a US-only reaction to the Fed.
• Gold and the dollar confirm it. Gold fell about 0.6% to near $4,157 on a day October hike odds dropped, and the dollar index held near its highest close since late July. Both fit a market paying for higher real yields rather than pricing an easier Fed.
• Stocks split along rate sensitivity. The Dow's 0.86% loss came with heavy selling in the last hour, while Nvidia and Microsoft each gained about 1.5%. The VIX at 16.34 says the selling was orderly, not a rush for protection.

Movers

Boeing rose about 2% after the Pentagon picked it for the Navy's F/A-XX fighter, a contract worth more than $20 billion, while Northrop Grumman, the losing bidder, fell about 3.5%.

United Therapeutics rose about 15% after a Delaware federal court found that Liquidia infringed its patent; Liquidia fell about 25% before trading was halted.

Rogers rose about 10% after raising its full-year earnings guidance to about $3.80 a share, above the $3.65 consensus.

Moderna fell more than 6% after Citi downgraded it to sell with a price target 60% below Tuesday's close.

What to watch

The thirty-year against its 2002 high. At about 5.63%, it is roughly 1 basis point below 5.644%. ISM manufacturing on Thursday and payrolls on Friday are the next tests. A close above 5.644% would take long yields to levels last seen in 2001. A close under 5.44% would say the rise is fading, not pausing. The two-year near 4.9% shows the Fed path is not what is moving the long end, so weaker data alone may not pull it down.

Micron's reaction on Thursday. Fiscal fourth-quarter revenue was $54.23 billion against about $50.45 billion expected, adjusted earnings $33.42 a share, and first-quarter guidance $61.5 billion, about $5 billion above consensus. The gross margin reached 87.0% and is guided at about 86.25%, so pricing has not yet softened. The stock still slipped about 1.2% after hours. Investors focused on capital spending of about $25 billion in the first half of fiscal 2027, part of an increase of more than $10 billion for the year, mostly for clean-room construction aimed at late 2028. A close above Wednesday's $1,066.10 would show demand outweighing the cost worry. A drop below $1,000 would make spending the issue for the chip sector.

Payrolls on Friday. Economists expect about 84,000 jobs, and ADP's 90,000 beat raises the chance of a stronger print. Above 150,000 would likely push October hike odds back above 60% and the ten-year above 5.30%. Under 50,000 would favour December and test whether short and long yields have stopped moving together.
