The S&P Global US flash Composite PMI jumped to 58.4 in September 2026 from 56.0 in August, its strongest reading since July 2021 and well above the 54.9 consensus estimate. Services rose to 58.7, while manufacturing PMI climbed to 57.0, pointing to a sharp acceleration in private-sector activity.
That is not a soft-landing print. Input costs rose at their fastest pace since October 2022, while supply delays also widened, raising fresh concerns that the economy is running too hot for the Federal Reserve to pause.
Markets reacted quickly, making macroeconomic shifts a trending hot topic among crypto traders. The 10-year Treasury yield moved above 5%, the dollar index rose above 101, and gold fell below $4,300. Bitcoin also slipped as odds of an October rate hike climbed, just a week after the Fed lifted rates to 3.75% to 4.00%.
This article examines what the PMI revealed, why it revived inflation and rate-hike fears, and how yields, the dollar, and ETF flows could affect Bitcoin ahead of the next FOMC decision.
What Does a US Composite PMI of 58.4 Actually Mean?
The PMI, short for Purchasing Managers’ Index, is a monthly survey of around 800 US companies. Each month, managers answer simple questions: Is business better or worse than last month? Are orders rising? Are you hiring? The answers are turned into a single score.
The key number is 50. A score above 50 means more companies say business is improving than say it is getting worse. Below 50 means the opposite. The “composite” version combines factories and service businesses such as retail, finance, and hospitality into one reading.
At 58.4, September’s score is well above that line. It means a large share of US businesses are growing at the same time, not just a few. The early estimate, released on 23 September 2026, showed growth speeding up for the fourth month in a row, and the 44th straight month above 50.
Most of that demand came from inside the US. New orders from customers rose to their highest in several years for both factories and service firms. Sales abroad were weaker: exports of goods kept falling, and service exports rose only slightly.
The survey also showed companies struggling to keep up. Unfinished work piled up at the fastest rate since May 2022. Suppliers took longer to deliver materials. Firms hired new staff at the fastest pace since June 2022, a rate rarely beaten since this data began in 2009.
In simple terms: US businesses are getting more work than they can finish quickly, and they are paying more to keep up. That is why the same report that showed strong growth also raised worries about rising prices.
Why Did September’s PMI Reignite Inflation Fears?
Business costs rose sharply alongside growth, and strong demand is giving companies more room to pass those costs on to customers.
The survey’s measure of business input costs climbed to 66.4 in September from 59.9 in August,according to Tech Times, with energy accounting for much of the increase. AsBrent and US crude both moved above $100 a barrel amid Middle East shipping disruptions, fuel and transport became more expensive for businesses across the economy.
Manufacturers faced additional pressure from shortages that pushed up raw material prices, while many firms in both sectors reported rising wages. The combined effect was strongest in services, where cost growth reached its highest level since November 2022.
Some of these higher costs are already reaching customers, as firms raised their own selling prices during the month. Competition has so far limited how much they can pass on, particularly in services, but S&P Global’s Chris Williamson cautioned that this restraint may not last. Companies facing more orders than they can fulfil, and struggling to hire, are increasingly in a position to raise prices.
This is the distinction the Federal Reserve is watching most closely. Price increases driven by energy tend to fade once oil prices retreat, which is why central banks often allow them to pass. Price increases driven by strong demand and labor shortages are more persistent, since they tend to spread into service costs such as rent, travel and healthcare.
September’s survey showed evidence of both, and markets responded to the risk that the more persistent form of inflation is returning.
How Does This PMI Fit the Fed’s September Rate Hike?
The PMI strengthens the case for the Federal Reserve to raise interest rates again in October, just weeks after it resumed hiking.
On 16 September 2026, the Fed’s rate-setting committee, the Federal Open Market Committee (FOMC), raised its benchmark interest rate by a quarter of a percentage point to a range of 3.75% to 4.00%. It was the first increase since July 2023, and all 12 voting members supported it. KuCoin’s breakdown of theSeptember 2026 FOMC decision covers the vote in more detail.
The Fed also signalled that it was not finished. Alongside each decision, policymakers publish their own forecasts for interest rates and the economy. Their middle estimate places rates at 4.1% by the end of 2026, which implies one more quarter-point increase this year. Only two of the 18 officials who submitted forecasts did not expect another rise, CNBC reported.
Their reasoning is clear from the rest of the projections: the Fed’s preferred inflation measure, which excludes food and energy, is expected to end 2026 at 3.4%, well above its 2% target, while economic growth of 2.3% and unemployment of 4.1% suggest the economy can withstand higher rates.
September’s PMI adds weight to that view. A single survey will not decide the Fed’s next move, but strong growth combined with rising costs makes it harder for officials to argue that one hike was enough. Markets adjusted quickly. On 23 September, following the PMI and supportive comments from Fed Governor Michael Barr, futures markets priced roughly a 73% chance of another quarter-point hike at the 27-28 October meeting, according to the same CNBC report.
The 2-year Treasury yield, which tracks expectations for Fed policy most closely, rose to 4.9%. These probabilities shift daily, so they reflect market expectations at a point in time rather than a settled outcome.
How Did Bitcoin and Crypto Markets React?
Bitcoin fell after the PMI release as rising bond yields, a stronger dollar and forced selling among leveraged traders weighed on prices. Institutional demand through spot Bitcoin ETFs, however, remained strong throughout the decline.
Why Do Rising Treasury Yields Put Pressure on Bitcoin?
Higher yields make interest-paying assets more attractive than Bitcoin, which pays no interest. After the PMI release, the 10-year Treasury yield climbed back above 5%, a level rarely seen in recent years and last reached briefly in October 2023.
When cash and government bonds offer better returns for little risk, some investors move money out of assets like Bitcoin. Higher rates also raise the cost of borrowing to trade crypto, which reduces the appetite for leveraged positions.
How Does a Stronger US Dollar Affect Crypto Prices?
A stronger dollar tends to weigh on Bitcoin and other assets priced in dollars. Following the PMI, the US dollar index rose above 101, a near two-month high, tightening the flow of money into riskier markets worldwide.
The pressure extended beyond crypto. Gold also fell below $4,300 on the same day, showing that investors across markets were adjusting to the prospect of interest rates staying higher for longer.
How Far Did Bitcoin Fall After the PMI?
Bitcoin fell roughly 4% from its recent high, trading near $84,000 on 24 September after failing to hold above $87,000 earlier in the week.According to Blockonomi, CoinGecko data showed Bitcoin at $83,863, down 3.8% over 24 hours, following a 21 September peak of $87,392, its highest level since January.
The pullback came after a strong run. Even after the decline, Bitcoin remained up nearly 10% over seven days, which suggests the PMI interrupted a rally rather than reversing a trend.
Analysts are now watching a few key levels. Bitfinex Alpha identifies $85,000 to $86,500 as the price range where the largest group of recent buyers entered the market, making it an important zone for Bitcoin to reclaim.
On the downside, analyst Rekt Capital has pointed to roughly $82,000 as the level Bitcoin needs to hold to stay positioned for further gains, while Bitfinex Alpha warned that a sustained move below $81,300, especially alongside ETF outflows, would weaken the case for the recent breakout.
Leverage also came down during the decline. Bitcoin open interest on Binance, a measure of outstanding futures positions, fell by about $500 million as traders reduced their exposure.
What Caused the Spike in Crypto Liquidations?
Much of the initial drop came from forced selling by leveraged traders. Traders who borrow to buy crypto must keep a minimum balance with their exchange. When prices fall far enough, their positions are closed automatically, and that selling can push prices lower still.
Around the time of the PMI release, CryptoSlate, citing CoinGlass, reported about $135.8 million in crypto liquidations. Roughly $125.9 million came from traders betting on rising prices, including about $47.4 million in Bitcoin and $23.9 million in Ether.
Are Spot Bitcoin ETF Inflows Still Strong?
Yes. Spot Bitcoin ETFs, which hold actual Bitcoin on behalf of investors, continued to attract new money despite the price drop. SoSoValue data reported by Blockonomi and CoinTurk showed US spot Bitcoin ETFs took in about $347 million on 23 September, led by BlackRock’s IBIT.
That extended a five-day run of inflows totalling roughly $2.65 billion, including about $999 million on 21 September, the largest single day since October 2025.
What Should Crypto Traders Watch Before the Next FOMC?
Five developments will shape whether the Fed raises rates again in October and how crypto markets respond. Each carries more weight than any single headline from this month’s early PMI estimate.
Final September PMI data (1 and 3 October): The figures released on 23 September were early estimates. Final manufacturing data is due on 1 October, followed by services and composite data on 3 October. Historically, the composite reading changes by only about 0.1 point on average between the early and final release, so a large downward revision is unlikely. A confirmed reading near 58 would reinforce the case for another hike.
Oil and transport costs: Energy was the main driver of September’s cost surge. If fuel prices fall quickly, business costs could ease on their own, giving the Fed less reason to act. If oil stays above $100, companies are more likely to pass higher costs on to customers, adding to inflation pressure.
Core inflation and wage growth: The Fed’s own projections show its preferred inflation measure, which excludes food and energy, ending 2026 at 3.4%, well above its 2% target. Upcoming inflation and wage data, particularly for services, will be the deciding factor in whether the Fed hikes or holds in October.
The 27-28 October FOMC meeting and the outlook beyond it: Markets already expect a hike, so the decision itself may matter less than what officials signal about future moves. As KuCoin’s FOMC analysis noted, crypto prices tend to react more to the expected path of interest rates than to any single decision. Even an anticipated hike could weigh on Bitcoin if the Fed hints at further increases into 2027.
Bitcoin ETF flows and the US dollar: Bitcoin’s rally earlier in the month was partly fuelled by traders closing bets against it, withabout $843 million in short positions liquidated as prices briefly topped $87,000. That source of buying has now largely run its course. For Bitcoin to climb back above $87,000 while yields remain high, it will need sustained buying from spot ETFs, which recorded a fifth straight day of inflows on 23 September, and other long-term investors. A weakening dollar would help; a stronger one would add resistance.
Could the Fed Skip a Rate Hike in October 2026?
Three developments could reduce the pressure on the Fed to raise rates in October, although none is strong enough on its own to reverse the outlook.
Falling energy prices: Much of September’s cost increase came from fuel and transport. If oil prices fall back, business costs could ease in the coming months, making September’s jump look like a temporary spike rather than a lasting trend.
A softer final PMI reading: The early estimate is based on about 85% of survey responses, so the final figure could come in lower. However, as noted above, revisions are usually small, so a strong growth reading is unlikely to disappear.
Fed patience on energy-driven inflation: Some officials may argue that higher fuel costs alone do not justify another hike, especially if underlying inflation continues to cool. That argument has become harder to make, though. In its September statement, the Fed dropped language linking high inflation to supply shocks, signalling that it now sees persistent inflation as a problem requiring action rather than patience.
Conclusion
September’s five-year-high Composite PMI shows that the US economy remains stronger than expected, but that strength is also keeping inflation risks alive. With input costs rising and the Fed already signaling another possible hike, markets are likely to remain sensitive to upcoming inflation, labor and PMI data.
For Bitcoin, higher Treasury yields and a stronger dollar could continue to create short-term pressure. However, persistent spot ETF inflows provide an important source of demand. The final PMI reading, energy prices, inflation data and ETF flows will therefore be key indicators to watch as the October FOMC meeting approaches.
