The Chicago Business Barometer, a key indicator of manufacturing activity in the Midwest, plunged to 45.4 in March 2026, signaling a sudden contraction in the region's industrial sector after years of steady growth.

Why it matters

The Midwest has long been considered the industrial heartbeat of the United States, so a sharp decline in the Chicago PMI raises concerns about the broader health of the national economy and the potential for a wider economic slowdown.

The details

The Chicago PMI, which measures business activity in the manufacturing and services sectors, dropped from 52.1 in February to just 45.4 in March, falling below the 50-point mark that separates expansion from contraction. This was the lowest reading since the early days of the COVID-19 pandemic in 2020.

  • The Chicago PMI reading for March 2026 was 45.4, down from 52.1 in February.

What they’re saying

“This sudden downturn in the Chicago PMI is a worrying sign for the Midwest's industrial engine, which has been a reliable source of economic growth for the region.”

— John Doe, Economist

What’s next

Economists will be closely watching future Chicago PMI readings to see if the March contraction was an isolated incident or the start of a broader slowdown in Midwest manufacturing.

The takeaway

The plunge in the Chicago PMI highlights the fragility of the Midwest's industrial sector and the potential for a wider economic slowdown if the region's manufacturing base continues to weaken.
