# Global Macro — Strong U.S. equipment demand collides with a 5% long-rate regime

The most important new signal since the September 25 edition is not another leg of the equity-versus-bond divergence. It is that U.S. business equipment demand remained unexpectedly strong even after the long end of the Treasury curve moved into territory not seen for almost two decades. Census reported that overall durable-goods orders were virtually unchanged in August, but non-defense capital-goods orders excluding aircraft — a widely used proxy for business equipment investment — rose 1.6% from July. Shipments of those core capital goods rose 0.6%. The data arrived after the previous Marginal Thinking daily was published and strengthen the case that productive investment, especially around digital and AI infrastructure, is still absorbing unusually high financing costs.

That does not make the rate shock benign. The Treasury's official September 25 curve closed at 5.17% for the 10-year and 5.49% for the 30-year, after the 10-year briefly traded above 5.22% during the session. At the same time, the University of Michigan's final September consumer-sentiment index fell to 48.1 from 51.7 in August and year-ahead inflation expectations rose to 4.6%. The new macro configuration is therefore more specific than “growth is strong”: capital spending is holding up while households report worsening confidence and the price of long-duration capital remains restrictive.

Oil provided partial relief on Friday. Brent settled at $104.32, down 2.1%, as U.S.-Iran negotiations raised the probability of a path toward reopening the Strait of Hormuz. That diplomatic support weakened on Saturday: President Donald Trump said he had rejected Iran's proposal to reopen the strait and end the fighting. Friday's oil decline therefore records a market repricing that was overtaken by a new political fact before the weekend ended; it is not evidence of physical normalization in Gulf logistics.

## Capital-goods orders make the investment cycle harder to dismiss

The August durable-goods release changed the composition of the U.S. growth signal. Total durable orders were effectively flat at $338.6 billion, restrained by transportation equipment. Excluding transportation, orders rose 0.3%. More important for the investment cycle, core capital-goods orders increased 1.6% after July was revised up to a 0.6% gain. Reuters reported that the category was 10.6% higher than a year earlier.

The detail matters. Orders for computers and related products rose 1.5% in August and were 20.1% above a year earlier; communications-equipment orders were up 35.8% year on year. Machinery orders also increased 1.1%. These numbers do not prove that all business investment is accelerating, and regional Federal Reserve surveys have shown some moderation in capital investment intentions. They do show that the physical investment cycle connected to computing, communications and equipment remains strong enough to coexist with a much higher discount rate.

That is the marginal information relative to September 25. Equity resilience can no longer be treated only as a valuation or sentiment phenomenon. Part of the support is linked to realized and ordered capital equipment. The important question is whether this spending broadens into a more general productivity cycle or remains concentrated in a narrow set of AI-linked and tax-sensitive investment categories.

## The long end is testing how much investment can be financed rather than stopping it immediately

The official Treasury curve shows how unusual the financing backdrop has become. The 10-year yield rose from 4.96% on September 22 to 5.11% on September 23, 5.18% on September 24 and 5.17% on September 25. The 30-year moved from 5.29% to 5.40%, 5.47% and 5.49% over the same dates. Real yields also remain high: Treasury's 10-year real constant-maturity rate was 2.83% on September 25 and the 30-year real rate was 3.22%.

This matters because a high nominal yield caused only by higher inflation would have a different investment implication from a high real yield. Real rates above recent norms raise the hurdle rate for projects whose cash flows arrive far in the future. That can coexist temporarily with very strong investment where expected returns are exceptional, as appears to be the case for some AI and computing infrastructure, but it makes weaker projects more vulnerable to cancellation, delay or repricing.

The current signal is therefore selection rather than a generalized capital strike. Strong firms and projects with high expected returns can still access capital; housing, smaller firms and projects with lower expected returns face a harder threshold. If long real yields remain around these levels, the distribution of investment should matter increasingly more than the aggregate amount.

## Household expectations are deteriorating while firms are still spending

The University of Michigan's final September sentiment index fell to 48.1 from 51.7 in August. The expectations component fell to 46.3 from 51.5. One-year inflation expectations rose to 4.6% from 4.0%, while five-year expectations edged up to 3.4%.

This is not a direct forecast of consumption. Sentiment can remain weak while spending holds up, and consumers may bring purchases forward when they expect prices to rise. But the combination is important for monetary transmission. If households expect higher prices and business investment remains strong, the Federal Reserve receives less evidence that aggregate demand has cooled enough to offset energy and trade-related inflation pressures.

That helps explain why Friday's durable-goods data pushed Treasury yields higher during the session even as oil was falling. The bond market is not responding to a single variable. Lower crude reduces one inflation impulse; stronger equipment demand and elevated inflation expectations preserve the case for restrictive policy and a high term premium.

## Friday's oil relief lost diplomatic support on Saturday; physical normalization remains absent

Brent fell $2.28 on Friday to settle at $104.32 and WTI fell $2.20 to $92.41. Reuters reported that U.S. and Iranian negotiators were exploring a phased arrangement that could include reopening the Strait of Hormuz and easing the U.S. blockade of Iranian ports. Ship-tracking data cited by Reuters showed 33.7 million barrels of crude moving out of the strait in the week beginning September 20, roughly in line with the previous week.

The Friday market reaction was understandable: even an increase in the probability of a diplomatic settlement lowers the expected value of severe disruption. The Saturday information set then moved the probability in the opposite direction. Reuters reported that Trump said he had rejected the Iranian proposal; Iran had transmitted the plan through Qatari mediators and offered to reopen the strait and end fighting within seven days. There is therefore no agreed near-term reopening path in the information set available for this edition.

For cross-asset analysis, the distinction is crucial. Expected de-escalation can lower oil and support bonds before insurers, shipping firms, ports, pipelines and commercial flows normalize, but a political reversal can restore the risk premium before any physical improvement occurs. Any renewed diplomatic channel should therefore be tested against observed throughput, freight, insurance, refined products and the operating status of alternative Gulf routes rather than treated as normalization on announcement.

```flow
Stronger equipment demand
-> firmer expected growth / investment returns
-> less pressure for rapid monetary easing
-> high nominal and real long-term yields

Friday expectation of Gulf de-escalation
-> lower expected energy disruption and oil prices
-> Saturday U.S. rejection of Iran's proposal
-> no verified reopening path; energy tail risk remains

Both channels meet
-> selective capital allocation rather than uniform easing or uniform contraction
```

## Equities are pricing productive upside that the bond market is charging heavily to finance

U.S. equities still rose on Friday: Reuters reported gains of 0.93% for the Dow, 0.51% for the S&P 500 and 0.48% for the Nasdaq, while the MSCI global equity gauge rose 0.53%. The coexistence of higher equity prices and long yields above 5% is not internally contradictory if investors expect a subset of firms to generate returns above the higher financing hurdle.

That is especially plausible where investment is financed from strong cash flow or where expected productivity gains are large. It is much less supportive for highly leveraged companies, long-duration projects without near-term cash generation, and sectors such as housing that depend directly on benchmark yields.

The analytical implication is that index resilience can overstate the breadth of financial accommodation. A market can reward a concentrated investment boom while the median borrower faces deteriorating financing conditions. Breadth, credit spreads, issuance quality and actual project cancellations therefore deserve more weight than headline equity indices alone.

## The next transmission test is whether capital investment broadens or becomes a concentration risk

There are two opposing interpretations of the current data. One is constructive: strong equipment orders show that firms are converting technological opportunity into physical investment, potentially lifting productivity and non-inflationary capacity later. The other is more restrictive: if the spending is concentrated in AI infrastructure while households, housing and rate-sensitive firms weaken, aggregate investment can look strong even as the economy becomes more dependent on a narrow capital-expenditure cycle.

The evidence does not yet decide between them. Core orders and shipments are strong; overall durable orders are flat; consumer sentiment is weak; inflation expectations are elevated; long real yields are restrictive. This combination argues for tracking composition rather than labeling the economy simply strong or weak.

A broader productivity cycle would become more credible if equipment investment diffuses across machinery, power systems, industrial automation and non-technology sectors while labor productivity improves. A concentration-risk interpretation would gain weight if AI-related orders remain strong but non-AI manufacturing, housing, smaller-company credit and labor demand deteriorate.

## What matters next

The weekend leaves three linked questions. First, can U.S. business investment continue to expand with 10-year nominal yields above 5% and real long rates near 3%? Second, after the U.S. rejection of Iran's proposal, does a new diplomatic channel emerge and translate into verified logistical normalization in the Gulf, or does energy risk reprice upward? Third, do household inflation expectations and next week's labor and inflation releases reinforce the case for further Federal Reserve tightening?

The contrary evidence to a broad tightening narrative is real: equities rose on Friday, equipment orders were strong and oil fell. The contrary evidence to a painless investment-boom narrative is also real: household confidence weakened, inflation expectations rose and the long end remains historically restrictive. The regime is therefore best described as **selective investment strength under expensive capital**. Saturday's rejection of the Iranian proposal also shows why Friday's energy relief should not yet be embedded as a durable disinflationary assumption.
