Strong US Growth Is Becoming the Market’s Problem

The PMI shock changes the risk distribution

The September US PMI print matters because it combined faster output growth with signs of firmer labor demand and cost pressure. S&P Global said the flash survey pointed to the strongest private-sector expansion in more than five years, while also highlighting hiring and input-cost dynamics that complicate the disinflation narrative.¹ Trading Economics separately noted that services activity rose to 58.7 and that input-cost pressures intensified.⁶

That mix is difficult for risk assets. A weak PMI would have revived recession hedges and rate-cut expectations. Instead, a 58.4 composite reading strengthens the argument that restrictive policy is not yet biting hard enough. Reuters reported that the hot survey lifted expectations for another Federal Reserve rate increase as yields and oil prices rose, adding to inflation concerns.³

Fed rhetoric is moving in the same direction. Governor Michael Barr said further policy adjustments would likely be needed, reinforcing the idea that stronger activity can translate into tighter financial conditions rather than better equity returns.¹¹

Long-duration assets are first in the firing line

The rise in the 10-year yield is the central transmission mechanism. Higher long-end yields increase the discount rate applied to future earnings, which tends to weigh most heavily on assets priced for long-term growth. That helps explain why a positive growth surprise can produce a negative equity reaction.

The pressure is not limited to technology or broad indices. Dow Jones reported that utilities shares fell amid a sharp increase in borrowing costs, a classic sign that rate-sensitive, bond-like equity sectors are being repriced.¹² Utilities are especially exposed because their dividend profiles compete with Treasuries, while their capital-intensive business models make higher financing costs more painful.

This is the broader valuation issue: if resilient US growth keeps the risk-free rate elevated, investors need more compensation to own equities, credit and other long-duration exposures. The hurdle rate rises even when earnings expectations are not collapsing.

Sterling assets face a relative-growth problem

The pressure also extends into FX and sterling assets. The UK flash PMI showed the composite output index slipping to 51.7 in September, signaling slower growth even as inflation pressures rose.⁷ That leaves the UK with a less favorable mix than the US: weaker activity, persistent price pressure and fewer clean policy options.

FXStreet reported that the pound sold off sharply as US survey data outpaced the UK’s, linking the divergence in activity momentum to GBP/USD weakness.⁸ Reuters also reported that the dollar was perched near a two-month high as hot PMI data fueled inflation fears and rate-hike bets.¹⁰

For sterling assets, the issue is not just dollar strength. It is relative macro credibility. If US yields rise because US activity is accelerating, while UK data show softer growth and lingering inflation, UK equities, gilts and sterling all face a tougher allocation backdrop.

Global resilience is not necessarily bullish

The US is not alone in showing firmer activity. S&P Global’s eurozone flash PMI indicated that regional growth reached its highest level since April 2023, while price pressures also rose.⁹ That supports the broader resilience theme, but it does not automatically improve the risk-asset outlook.

A synchronized improvement in activity can be bullish when inflation is falling and central banks are preparing to ease. It is more complicated when price pressures remain visible and long-end yields are rising. In that environment, better growth can extend the period of restrictive policy and keep global discount rates elevated.

The market’s repricing therefore reflects a shift in the dominant risk. Investors are no longer trading only the probability of recession. They are trading the probability that demand stays strong enough to keep policy tight, yields high and valuations under pressure.

Bottom line

September’s US PMI surprise is a reminder that macro resilience can be bearish for financial assets when inflation and policy risks remain unresolved. The stronger the US data look, the harder it becomes for markets to price imminent relief from the Fed. That keeps upward pressure on yields, supports the dollar, weighs on sterling and challenges rate-sensitive sectors.

The risk is not that the economy is suddenly too weak. It is that it is still too strong.
