The price shock is in North Carolina's budgets. It is not yet embedded in them.

September's consumer price index put US inflation at 3.7% over the year, and the breadth of the rise, across energy, shelter, vehicles and tariff-sensitive goods, has been widely read as a sign that higher costs are now embedded in business budgets.

For North Carolina, on the public evidence to 19 October, the costs are in budgets. They are not yet embedded.

The headline is a household measure. A firm's budget is built from different lines, and those lines are moving at very different speeds.

We traced the shock channel by channel through North Carolina's main sectors, using public statistical releases, utility and tariff filings, central-bank business surveys and company disclosures. Each channel was tested against thresholds fixed before any sector was scored: material at 2% or more of a sector's output, persistent if increases hold across successive monthly releases, and embedded only if second-round effects, above all in wages, appear as well.

For most firms the decisive line is freight. Producer diesel prices rose 115.2% over the year and truck freight prices 19.3%. Direct fuel is a material cost for only two sectors, trucking and construction. Purchased freight is material for every sector that moves goods, and trucks carry 86% of North Carolina's freight tonnage. Across the state's main sectors, indicative first-round impacts range from about 0.4 to 5.6 points of gross output. Those are estimates on national cost coefficients, because no state-level tables exist.

So far the pressure sits in margins. Firms in the Carolinas report prices paid rising 6.38% against prices received 3.88%. About half of North Carolina firms are paying more; only a fifth are charging more. Wages are not accelerating, and North Carolina real weekly wages are down 0.5% on the year. On the study's definition, that is cost pressure in budgets, not yet embedded in them.

Not everything is moving the same way

North Carolina's price level is 94.3% of the national level. Consumer pass-through of the 2025 tariffs is judged effectively complete, with core goods prices up only 0.7%. Rail freight prices have barely moved, at 1.3%. And one of the dated 2027 cost steps runs the other way: workers' compensation loss costs fall 10.6% from April 2027.

Two things surprised us

Our view, for what it is worth

We think 3.7% is the wrong planning number for most North Carolina firms. The useful numbers are freight, electricity, occupancy, repair and the cost of long-term capital, and several 2027 steps are already dated: pending utility settlements would add about 3.4% to 3.7% a year to electricity bills from January 2027 if approved, and tariffs on furniture and cabinets step up on 1 January. Whether absorbed costs become embedded prices turns on wages, and the next few monthly releases will show which way that goes. A board could reasonably ask:

These are questions, not advice. The decision stays with the people who hold it.

The study covers the public record to 19 October 2026. If that record misses something you know, we would like to hear it.
