Treasuries: ISM Price Surge Sparks Stagflation Fear
Key Takeaways
- ISM Manufacturing Prices Paid surged to 70.5 in February, more than 12 points above the 58.2 consensus estimate, signaling a sharp reacceleration in factory-gate inflation.
- Manufacturing employment has declined by 81,000 jobs over 12 months to 12.59 million, creating a textbook stagflation divergence: rising costs alongside weakening employment.
- The 10-year Treasury yield has fallen to 4.02%, testing the 4% floor, but the ISM data complicates the bond rally by introducing cost-push inflation risk.
- A critical macro data chain unfolds over the next two weeks: NFP (March 6), CPI (March 11), GDP/Core PCE (March 13), and the FOMC meeting (March 18).
- Treasury investors should favor short-duration positions and TIPS until March CPI data confirms or denies the pass-through from producer to consumer inflation.
The ISM Manufacturing Prices Paid index surged to 70.5 in February 2026, smashing the consensus estimate of 58.2 and marking the highest input-cost reading in months. The magnitude of the surprise — more than 12 points above expectations — sent a clear signal: factory-gate inflation is reaccelerating even as the broader economy shows signs of cooling.
This divergence matters for Treasury investors because it arrives alongside a sharply weaker employment outlook. Non-Farm Payrolls estimates for March 6 have dropped to just 70,000, half the prior reading of 130,000. Rising input costs paired with weakening job creation is the textbook definition of stagflation — the worst-case scenario for central bank policymakers who must choose between fighting inflation and supporting growth.
The 10-year Treasury yield has drifted down to 4.02% as of late February, retreating from 4.18% earlier in the month. But the ISM data complicates the bond rally narrative. If inflation pressures are building at the producer level, they will eventually pass through to consumer prices — potentially stalling the Federal Reserve's rate-cutting cycle just as the labor market softens. The next two weeks of data releases (NFP March 6, CPI March 11, GDP/Core PCE March 13, and the FOMC meeting March 18) will determine whether this stagflation signal is a one-off anomaly or the start of something more concerning.
ISM Prices Paid: The Stagflation Signal
The ISM Manufacturing Prices Paid index measures the rate of change in input costs for U.S. manufacturers. A reading above 50 indicates rising prices; above 60 signals accelerating inflation; and above 70 historically corresponds to periods of intense cost pressure that tend to feed through to consumer prices within 3-6 months.
February's 70.5 reading doesn't just clear those thresholds — it obliterates them. The consensus estimate of 58.2 already priced in moderate cost increases, but the actual figure suggests manufacturers are facing a supply-side price shock. Raw materials, energy costs, and supply chain bottlenecks are all contributing to what could be a durable shift in the inflation regime.
The last time ISM Prices Paid sustained readings above 70, the Federal Reserve was forced to halt rate cuts and signal tighter policy ahead. Treasury markets responded with a bear flattening — long-term yields rose on inflation fears while short-term yields stayed anchored by the Fed's reluctance to hike aggressively.
What makes this reading particularly alarming is the context. Manufacturing employment has been steadily declining — from 12,671,000 workers in February 2025 to 12,590,000 in January 2026, a loss of 81,000 jobs over 12 months. Factories are paying more for inputs while simultaneously shedding workers. This is not the kind of inflation that comes from a booming economy; it's the kind that comes from supply constraints and cost-push pressures — the hallmark of stagflation.

Treasury Yield Landscape: The 4% Battleground
The benchmark <a href="/posts/2026-02-25/treasuries-rally-accelerates-as-10-year-yield-breaks-below-405-on-growth-fears-and-flight-to-safety">10-year Treasury</a> yield has fallen to 4.02% as of February 26, testing the psychologically important 4% floor that has acted as support since mid-February. The move lower reflects a <a href="/posts/2026-03-01/treasuries-iran-crisis-drives-flight-to-safety">flight to safety</a> driven partly by geopolitical tensions and partly by growth concerns as the NFP estimate plunged.
Across the <a href="/posts/2026-03-01/treasury-yield-curve-what-the-spread-tells-you-now">yield curve</a>:
- 2-Year Treasury: 3.42%, down from 3.52% on February 11
- 10-Year Treasury: 4.02%, down from 4.18% on February 11
- 30-Year Treasury: 4.67%, down from 4.82% on February 11
- 10Y-2Y Spread: +0.60%, maintaining a positively sloped curve
The positive slope of the yield curve — with the 10Y-2Y spread at 60 basis points — is noteworthy. A positively sloped curve typically signals expectations of stronger growth or higher inflation ahead. But in the current context, it may reflect something more troubling: the market is pricing in inflation persistence at the long end while expecting the Fed to cut rates at the short end to support a weakening labor market. That's a stagflationary signal embedded in the curve itself.
The 10-year breakeven inflation rate stood at 2.25% as of February 27, slightly below recent levels but still elevated enough to suggest the market hasn't fully dismissed inflation risks. If the ISM Prices data starts feeding through to consumer prices, breakevens could move materially higher — pushing nominal yields up even as real growth deteriorates.
The Macro Calendar Chain: What Comes Next
The ISM Prices Paid report is the opening salvo in what will be the most consequential two-week stretch of economic data in 2026. Each release builds on the last, and Treasury markets will price and reprice the stagflation narrative with every new data point.
March 6 — Non-Farm Payrolls (NFP): The consensus estimate of 70,000 new jobs would represent a dramatic slowdown from the prior reading of 130,000. If confirmed, it would be the weakest monthly jobs report since the pandemic recovery. For <a href="/posts/2026-02-27/how-treasury-bonds-work-t-bills-t-notes-t-bonds-and-tips-explained">Treasuries</a>, a weak NFP would typically be bullish (lower yields), but the ISM Prices data complicates that trade. Weak jobs + high inflation = stagflation, and stagflation is bearish for bonds at the long end.
March 11 — CPI and Core CPI: This is the critical test. ISM Prices Paid leads consumer inflation by roughly one quarter. If January's CPI (326.588, up from 319.679 a year ago, implying roughly 2.2% annual inflation) shows any uptick, it will validate the ISM signal. Core CPI — which strips out food and energy — will reveal whether the cost pressures are broad-based or confined to commodity-sensitive sectors.
March 13 — GDP, Core PCE, JOLTs, Michigan Sentiment: A data deluge. GDP growth tells us the demand side of the equation. Core PCE is the Fed's preferred inflation gauge — if it ticks higher alongside the ISM data, the stagflation narrative hardens. JOLTs job openings and Michigan consumer sentiment will fill in the picture on labor demand and household confidence.
March 18 — FOMC Decision and Dot Plot: The culmination. With the Fed funds rate currently at 3.64% (January 2026 effective rate), the Fed has already cut from the 4.33% level that prevailed through most of 2025. The question now is whether the ISM Prices data forces a pause in the cutting cycle. The dot plot — which maps individual FOMC members' rate projections — will be scrutinized for any hawkish shifts.
Manufacturing Employment: The Other Side of Stagflation
While input costs surge, the manufacturing labor market tells a starkly different story. Manufacturing employment (MANEMP) has declined in every month since mid-2025:
- February 2025: 12,671,000
- June 2025: 12,636,000
- October 2025: 12,603,000
- January 2026: 12,590,000
That's a loss of 81,000 manufacturing jobs over 12 months — a slow but persistent bleed that suggests factories are responding to margin pressure by cutting headcount rather than absorbing higher costs. When manufacturers face rising input prices but can't pass them on to customers (because demand is softening), they cut workers instead. This is classic late-cycle behavior.
For Treasury investors, the manufacturing employment trend reinforces the stagflation thesis. The Fed's dual mandate — maximum employment and stable prices — is being pulled in opposite directions. Cutting rates further would risk stoking the inflation that ISM Prices is already signaling. Holding rates steady or hiking would accelerate the labor market deterioration that's already underway.
The 10-year breakeven inflation rate at 2.25% suggests the <a href="/posts/2026-03-02/treasuries-march-data-barrage-tests-4-floor">bond market</a> hasn't yet fully priced in the ISM signal. If March CPI confirms the pass-through from producer to consumer prices, breakevens could move toward 2.40-2.50%, putting upward pressure on nominal yields even as the growth outlook darkens.
Investor Outlook: Positioning for the Data Barrage
The two weeks ahead will be among the most volatile for Treasuries in 2026. The ISM Prices data has introduced a new variable — cost-push inflation — that wasn't priced into the consensus view of a smooth Fed cutting cycle and gradually declining yields.
Bull case for Treasuries: NFP comes in below 70K, signaling a sharper labor market downturn. The ISM Prices surge was a one-off driven by energy and geopolitical factors (Iran conflict, oil price spikes), and Core CPI on March 11 shows no pass-through. The Fed cuts again, the 10-year yield breaks below 4%, and the flight-to-safety trade extends.
Bear case for Treasuries: NFP surprises to the upside (or holds near 130K), removing the growth scare. But CPI confirms the ISM signal with an upside surprise. The Fed pauses, dot plots shift hawkish, and the 10-year yield climbs back toward 4.20%. The long end of the curve sells off as inflation expectations reprice higher.
Stagflation scenario: The worst outcome for bond investors. NFP confirms the labor market weakening (below 100K), but CPI and Core PCE both surprise higher. The Fed is trapped — it can't cut into rising inflation, and it can't hike into a weakening job market. The yield curve bear-steepens as the long end reprices inflation risk while the front end stays anchored. The 10-year could push toward 4.30% while the 2-year holds near 3.40-3.50%.
For investors holding intermediate-duration Treasuries (5-7 years), the current environment favors patience. The 4% level on the 10-year is a reasonable entry point if the growth scare materializes, but the ISM data argues against going long duration until CPI confirms whether the inflation signal is real or noise. Short-duration positions and TIPS (Treasury <a href="/posts/2026-03-01/tips-how-us-inflation-protected-treasury-bonds-work">Inflation-Protected</a> Securities) offer better risk-adjusted exposure until the March data resolves the stagflation question.

Conclusion
The ISM Manufacturing Prices Paid surge to 70.5 — more than 12 points above consensus — has fundamentally altered the Treasury market narrative heading into March. What was expected to be a straightforward story of declining yields and steady Fed rate cuts now confronts the possibility of cost-push inflation reaccelerating at exactly the wrong moment.
This article is the first in a series tracking the macro data chain through the FOMC meeting on March 18. Each subsequent data release — NFP, CPI, GDP, Core PCE — will either reinforce or undermine the stagflation signal that ISM has fired. Treasury investors should watch the 10-year breakeven inflation rate (currently 2.25%) as the real-time market gauge of whether the ISM price pressures are feeding through to broader inflation expectations.
The 4% floor on the 10-year yield is the immediate battleground. If March data confirms weakening growth without inflation pass-through, that floor breaks lower. If both the growth scare and the inflation scare prove real, Treasuries face a more challenging environment where neither the bull case nor the bear case wins cleanly — and stagflation becomes the dominant narrative for the first time since the post-pandemic era.
