The Institute for Supply Management's (ISM) Manufacturing Purchasing Managers' Index remains one of the most closely watched economic indicators in the United States. As we reflect on recent trends spanning both the past two years and the broader decade-long trajectory, a nuanced picture of American manufacturing emerges—one marked by resilience, structural challenges, and the enduring impact of global disruptions.
The Recent Struggle: Two Years of Persistent Contraction
The past two years have been particularly challenging for U.S. manufacturing. From November 2023 through October 2025, the PMI has remained in contraction territory for an overwhelming majority of the period—hovering around an average of 48.4, well below the critical threshold of 50 that separates expansion from contraction.

What's particularly striking about this period is the persistence of the weakness. Unlike brief contractionary episodes that might reflect temporary supply chain disruptions or seasonal factors, this extended period below 50 suggests deeper structural headwinds. The manufacturing sector has expanded in only 12.5% of the months during this two-year window—a stark indicator of sustained pressure on the sector.
Key Observations from the Recent Period
- Interest Rate Impact: The Federal Reserve's aggressive rate hikes to combat inflation have dampened demand for durable goods, directly impacting manufacturing orders.
- Inventory Adjustments: After the pandemic-era inventory buildup, manufacturers have been working through excess stock, leading to reduced production needs.
- Global Uncertainty: Geopolitical tensions and shifting trade patterns have created hesitancy in capital investment and long-term manufacturing commitments.
- Production Volatility: The Production Index has shown significantly higher volatility (standard deviation of 2.27) compared to the overall PMI, indicating operational instability.
The Decade in Perspective: From Boom to Bust and Back
Zooming out to examine the full decade from 2015 to 2025 provides essential context for understanding current conditions. This ten-year journey encompasses periods of robust expansion, a historic pandemic-induced collapse, an extraordinary recovery, and now, a period of recalibration.

The Pre-Pandemic Era (2015-2019): The mid-to-late 2010s represented a period of steady, if unspectacular, manufacturing growth. PMI readings consistently hovered in the low-to-mid 50s, reflecting moderate expansion supported by stable global trade, low interest rates, and steady consumer demand. The 2017-2018 period was particularly strong, with readings frequently in the upper 50s, buoyed by corporate tax cuts and business optimism.
The COVID Shock (2020): April 2020 marked the steepest decline in manufacturing activity in modern history, with the PMI plummeting to 41.5. This wasn't merely a contraction—it was a near-complete halt of manufacturing operations as lockdowns shut down factories and severed supply chains. The recovery that followed was swift but bumpy, characterized by unprecedented supply-demand mismatches.
The Post-COVID Boom (2021): The manufacturing sector experienced its most robust expansion in decades during 2021, with PMI readings soaring above 60 for extended periods—peaking around 64.7 in March. This remarkable surge was driven by pent-up demand, government stimulus, and aggressive restocking. However, this proved to be unsustainable, as supply chains remained constrained and labor shortages intensified.
The Current Adjustment Phase (2022-2025): Since the 2021 peak, manufacturing has been in a protracted adjustment phase. The rapid ascent gave way to a gradual but persistent decline. By 2023, the index had returned to contraction territory and has largely remained there through 2025. This reflects not just cyclical weakness but potentially structural shifts in how and where goods are manufactured.
Decade-Long Trends: What the Data Reveals
- Volatility Increased: Manufacturing activity has become significantly more volatile compared to the pre-pandemic era, reflecting greater economic uncertainty.
- Shorter Cycles: The boom-bust cycles have compressed—from pandemic collapse to record expansion to persistent contraction in just five years.
- Structural Shifts: The decade has seen manufacturing increasingly sensitive to interest rates, highlighting the sector's growing capital intensity.
- Resilience Despite Challenges: Even during periods of contraction, the PMI has remained above the 42.3 level that historically signals recession, suggesting manufacturing weakness alone hasn't dragged down the broader economy.
What This Means for the Future
The ISM Manufacturing PMI tells a story of a sector in transition. The persistent weakness over the past two years doesn't necessarily portend economic disaster—the broader economy has remained relatively resilient, supported by strong services sector performance and robust consumer spending. However, the manufacturing data does signal important shifts:
First, the days of easy manufacturing growth may be behind us. The combination of higher interest rates, increased automation, shifting global supply chains, and deglobalization pressures creates a more challenging environment for traditional manufacturing expansion.
Second, the volatility of the past decade suggests that manufacturing will remain highly sensitive to external shocks—whether pandemic-related, geopolitical, or monetary policy-driven. Businesses and policymakers must build greater resilience into manufacturing operations and supply chains.
Third, the disconnect between overall PMI and production volatility hints at operational challenges beyond simple demand fluctuations. Companies are grappling with workforce issues, technological transitions, and fundamental questions about optimal production locations.
Conclusion
As we look at the ISM Manufacturing PMI data spanning the last two years and the broader decade, we see a sector that has weathered extraordinary challenges—from a global pandemic to radical shifts in monetary policy to evolving trade dynamics. The current period of contraction, while concerning, must be viewed within this broader context. Manufacturing is not collapsing but adapting, seeking a new equilibrium in a fundamentally changed economic landscape.
For investors, business leaders, and policymakers, the key insight is this: manufacturing's path forward will be neither a return to the steady expansion of the 2010s nor a repeat of the pandemic-era volatility. Instead, we're likely entering a period of moderated growth characterized by greater efficiency, increased automation, and a more nuanced relationship with global supply chains. Understanding these trends through the lens of PMI data remains essential for navigating the economic terrain ahead.
