The Signal: Input Cost Inflation Has Reaccelerated
The warning signals are no longer subtle. Factory input costs have accelerated for four straight months. The ISM Manufacturing Prices Index surged to 70.5 in February 2026 — the highest reading since mid-2022 — driven by a sharp spike in metals, energy, and tariff-related costs. Global PMI data from S&P Global tells the same story: producer price growth hit its steepest pace in three years entering 2026.
Global factory input costs accelerated for the fourth straight month
PMI input prices rose sharply. The ISM Prices Index leapt from 59.0 to 70.5 — a reading historically associated with rapid inflationary spikes that force Federal Reserve action.

The U.S. Manufacturing PMI registered 52.4 in February, confirming the sector is expanding. But the expansion comes at a cost. Input prices are rising faster than output prices, which means margin erosion is already underway for manufacturers who haven't adjusted.
For manufacturing CEOs and CFOs, this isn't a footnote on an economic dashboard. It's a direct threat to the P&L.
The Tariff Transmission Lag and Supply Delays
A significant driver of today's cost acceleration is trade policy. Shifting tariff structures throughout early 2026 — including a pivot to a new 10% global tariff under Section 122 of the Trade Act — have created a compounding effect on raw material costs, particularly in metals and energy. Copper and steel prices have surged, driven by geopolitical uncertainty and tariff escalation.
Suppliers can't absorb these costs indefinitely. The lag between tariff imposition and P&L impact is typically one to two quarters, which means the full effect of February's policy changes hasn't hit yet.
Supplier delivery times are also stretching to one of the greatest extents since the pandemic-related supply constraints of 2022. The ISM Supplier Deliveries Index rose to 55.1, indicating that vendors aren't just charging more — they're struggling to keep pace with orders. More expediting. More premium freight. Less room for pricing errors or surprises.
Why Margin Compression Isn't Just a Sourcing Problem
When executives hear "input cost inflation," many default to procurement. Renegotiate contracts. Squeeze suppliers. That response is understandable, but it misses the broader picture. Cost inflation hits the entire financial engine, and the damage compounds across functions.
Cost inflation outruns pricing power
When input costs accelerate faster than you can adjust pricing, every unit shipped erodes margin. The gap widens quickly.
More expediting, more buffers
Premium freight and safety stock tie up cash. What looks like a supply chain decision becomes a liquidity problem.
Assumptions go stale fast
Budgets built on stable pricing assumptions break within quarters. Rolling forecasts can't keep pace with tariff-driven volatility.
Inventory rises to protect service
Supplier delivery delays worsen. Companies build buffer stock, and capital sits on warehouse floors instead of funding growth.
Margin pressure is a systems problem, not a one-time negotiation. The companies that defend margin most effectively treat it that way.
What Many Companies Get Wrong
Under margin pressure, the instinct is to act fast. But fast and blunt are different things. The most common responses we see are also the least effective.
The fix: move early, with facts. Precision improves margin. Blunt actions just reduce noise.
A Better Approach: Precision Over Pressure
Tenet's approach to margin defense starts with clarity. We don't begin with a supplier list — we begin with a fact base. What are you spending? With whom? Against what market benchmarks? Where are the structural cost drivers versus cyclical inflation? That diagnostic precision is what separates a margin defense program from a procurement fire drill.
By building a wave plan that targets the highest-exposure categories first, the program generates quick wins that fund the broader transformation — and demonstrates credibility to the executive team within weeks, not months.
| Category | Annual Spend | Savings | % Reduction |
|---|---|---|---|
| Hydraulics | $87M | $21.8M | 25% |
| Castings | $71M | $7.1M | 10% |
| Drivetrain | $41M | $7.0M | 17% |
| Electrical | $22M | $1.8M | 8% |
| Total | $221M | $37.7M | 17% avg |
"This became the biggest program in the company. Nothing else comes close in impact. It's a cash machine — first from cost savings, then from innovation."
— Tom Verbaeten, Chief Supply Chain Officer, CNH Industrial
A Margin Defense Checklist for Q2 2026
If your organization is feeling the squeeze, the time to act is now — before the tariff transmission lag delivers its full impact. Here's where disciplined companies are focusing:
- Rapid margin exposure assessment. Map your top categories and suppliers against current market benchmarks. Identify where cost inflation is structural versus cyclical.
- Wave plan focused on the biggest opportunities first. Sequence sourcing actions by exposure and potential impact. Don't spread effort evenly — concentrate it where savings are largest.
- Supplier actions tied to structural cost reduction. Go beyond price renegotiation. Should-cost analysis, specification optimization, supply base rationalization, and alternative sourcing.
- Cross-functional alignment. Margin defense isn't a procurement initiative — it's an executive priority. Finance, engineering, operations, and sourcing need to move in concert.
- Capability transfer. Training your team in strategic sourcing methodology means the savings compound year over year. That's how you build a permanent advantage.
