US PMI Hits a Five-Year High at 58.4 as October Fed Rate-Hike Odds Jump to 73%

Key Takeaways

• The S&P Global flash US Composite PMI climbed to 58.4 in September from 56.0 in August, recording its highest reading since July 2021.
• Services activity accelerated to 58.7, while the Manufacturing PMI jumped to 57.0 as output, new orders and factory employment strengthened.
• Input-cost inflation rose sharply to its highest level since October 2022, reinforcing concerns that rapid economic growth could keep inflation elevated.
• Markets increased the probability of another Federal Reserve rate hike in October to approximately 73%, up from 53% before the PMI report.
• The 10-year Treasury yield surged above 5%, the dollar strengthened, US stocks declined and gold fell below $4,300 per ounce.

US private-sector activity expanded at its fastest pace in more than five years during September, strengthening expectations that the Federal Reserve could raise interest rates again in October.

The S&P Global flash US Composite PMI rose to 58.4 from 56.0 in August, reaching its highest level since July 2021. Both manufacturing and services reported faster growth, while new orders, employment and input costs increased.

The unexpectedly strong report pushed the market-implied probability of an October Fed rate hike from 53% to approximately 73%. US Treasury yields moved sharply higher, placing pressure on technology stocks, gold and other rate-sensitive assets.

What Did the September US PMI Report Show?

The Composite PMI measures business activity across the US manufacturing and services industries. A reading above 50 indicates expansion, while a figure below 50 signals contraction.

At 58.4, the September reading showed that economic activity was expanding at a considerably faster rate than during the previous month.

Services remained the largest contributor to growth, but the improvement in manufacturing was particularly significant. Factory output accelerated, new orders increased and manufacturing employment rose at its fastest pace since February 2021.

The stronger manufacturing figures suggest the expansion is becoming less dependent on consumer-facing services. That could improve the economy’s resilience, but it also increases the risk that demand will continue to exceed available supply.

S&P Global’s historical comparisons suggest the survey is consistent with annualized economic growth of approximately 5%, while third-quarter output may be expanding at close to a 4% pace.

The PMI figures are preliminary and can be revised when the final report is published. Nevertheless, the strength of the flash estimate was sufficient to trigger an immediate repricing across financial markets.

Input Costs Raise New Inflation Concerns

The most important detail for the Federal Reserve may not be the headline growth rate but the sharp rise in business costs.

The input-cost index increased from 59.9 to 66.4, reaching its highest level since October 2022. Companies reported pressure from wages, energy, raw materials and transportation expenses.

Oil prices remain above $100 per barrel because of the conflict with Iran, restrictions around the Strait of Hormuz and record tanker costs. Higher fuel and shipping expenses could feed into the prices of goods and services during the coming months.

Strong demand also gives businesses more ability to pass rising costs on to customers. If companies retain pricing power, the Fed may become less confident that inflation will return sustainably to its 2% target.

The combination of rapid growth and higher input costs presents a difficult policy environment. The economy appears strong enough to withstand tighter monetary policy, while inflationary pressure may require the central bank to act again.

October Fed Rate-Hike Odds Rise to 73%

Interest-rate markets reacted quickly to the PMI release.

Fed funds futures raised the probability of a rate increase at the October meeting to approximately 73%, compared with 53% earlier in the session. Traders are increasingly considering whether the September increase marked the beginning of a renewed tightening cycle rather than a single policy adjustment.

The Federal Reserve raised its target range by 25 basis points to 3.75%–4% at its September meeting, completing its first increase in three years. The latest dot plot also indicated that most policymakers expect at least one additional hike during 2026.

Fed Governor Michael Barr reinforced the hawkish interpretation by saying that the central bank’s September decision was an important step toward recalibrating borrowing costs and that further increases would probably be required.

The central bank must now weigh several competing factors:

• Business activity is expanding at its fastest pace in more than five years.
• Manufacturing employment and new orders are strengthening.
• Input-cost inflation is accelerating.
• Oil prices remain high and could increase consumer inflation.
• Higher borrowing costs are beginning to weigh on housing and financial markets.
• Parts of the labour market have shown signs of cooling.

For the October meeting, incoming inflation and employment data will determine whether the Fed delivers another 25-basis-point increase.

Treasury Yields Surge Above 5%

The bond market experienced one of the strongest reactions to the PMI report.

The two-year Treasury yield, which is particularly sensitive to Federal Reserve policy expectations, rose by approximately 8.5 basis points to 4.862%. That was its highest level since June 2024.

The 10-year Treasury yield climbed by approximately 8.7 basis points to 5.054%, its highest level since 2007. It later traded near 5.1% as selling pressure continued.

A weak five-year Treasury auction added to the move. The $70 billion sale produced a yield of 5.033% and a bid-to-cover ratio of 2.21, below the previous 12-month average of 2.37. The results suggested investors required higher returns to absorb additional US government debt.

Higher yields increase financing costs for households, businesses and the federal government. They also make bonds more competitive with stocks, particularly technology companies whose valuations depend heavily on earnings expected years into the future.

Reuters market data confirmed that the 10-year yield reached its highest level in 19 years as traders increased their expectations for another Fed hike.

Nasdaq Falls From Its Record High

US stocks declined as the bond-market selloff tightened financial conditions.

The Nasdaq Composite fell 1.13% to 26,936.04, ending its two-session run of record closing highs. The S&P 500 dropped 0.75% to 7,706.03, while the Dow Jones Industrial Average lost 0.68% to 51,511.59.

The Russell 2000 declined 1.8%, reflecting the sensitivity of smaller companies to rising financing costs.

Technology stocks faced particular pressure because higher yields reduce the present value of future earnings. The selloff came only one day after the Nasdaq closed at a record 27,244.28, demonstrating how quickly interest-rate concerns can reverse AI-driven market momentum.

The latest decline does not necessarily end the technology rally. However, it indicates that strong earnings and AI enthusiasm may struggle to offset a sustained rise in risk-free yields.

The Dollar Strengthens as Gold Falls Below $4,300

The prospect of higher US interest rates also supported the dollar.

EUR/USD fell approximately 0.5% to 1.1389, its lowest level since July 29. USD/JPY climbed to around 158.25 before easing, placing the pair closer to the 160 level associated with elevated Japanese intervention risk.

Gold experienced a sharper reaction. Spot prices fell about 1.6% to approximately $4,286 per ounce, breaking below the $4,300 threshold.

Gold does not generate interest income, so rising Treasury yields increase the opportunity cost of holding the metal. A stronger dollar also makes bullion more expensive for buyers using other currencies.

Silver fell nearly 4% to around $64.33 as the combination of higher yields, a stronger dollar and weaker risk sentiment pressured precious metals. Kitco’s market report showed how the PMI surprise affected equities, bonds, currencies and metals simultaneously.

Does Stronger PMI Mean the Fed Will Definitely Hike?

The PMI report significantly strengthened the case for another increase, but an October rate hike is not guaranteed.

A 73% market probability still leaves a meaningful chance that the Fed will keep rates unchanged. Policymakers will receive additional labour, inflation and consumer-spending figures before the meeting.

The most important upcoming releases include:

• Weekly initial jobless claims
• Durable goods orders
• University of Michigan consumer sentiment and inflation expectations
• Personal Consumption Expenditures inflation
• September employment figures
• Consumer Price Index data

A further series of strong releases would likely push rate-hike expectations closer to certainty. A sudden deterioration in employment, financial conditions or consumer demand could encourage the Fed to pause.

The central bank will also monitor the effect of Treasury yields above 5%. Rising market rates can tighten financial conditions without an immediate policy-rate increase, potentially reducing the need for the Fed to act.

What the PMI Report Means for Markets

The September PMI data strengthens the argument that the US economy remains more resilient than other major developed economies. That relative strength supports the dollar and could continue attracting international capital toward US assets.

However, rapid growth is not entirely positive for markets. If the economy is expanding too quickly for inflation to decline, the Fed may need to keep rates higher for longer.

The immediate implications are:

• US dollar: Supported by higher yields and rate-hike expectations.
• Treasuries: Vulnerable if inflation and growth data remain strong.
• Technology stocks: Pressured by higher discount rates and bond competition.
• Gold: Exposed to additional short-term weakness if real yields rise.
• Oil: Supported by geopolitical supply risks, but higher rates may eventually weaken demand.
• USD/JPY: Biased upward, with intervention risk increasing near 160.

The September PMI report has shifted the central market question. Investors are no longer asking whether the US economy can avoid a recession. Instead, they are considering whether growth is too strong for the Federal Reserve to stop tightening.
