American factories, mines, and power plants collectively pushed output higher for another month. The Federal Reserve reported that US industrial production rose 1.7% year-over-year in May 2026, a step up from the revised 1.4% annual increase recorded in April.

The industrial production index now sits at 102.6% of its 2017 average.

What’s driving the numbers

The month-over-month picture is more subdued. Industrial production grew just 0.1% from April to May, a notable deceleration from the 0.9% monthly jump the prior month.

Beneath the headline number, the sector-level breakdown tells a more nuanced story. Manufacturing output, the largest component of industrial production, was essentially flat in May. Mining picked up the slack with a 1.3% increase, while utilities actually dragged things down with a 0.4% decline in output.

Capacity utilization, which measures how much of the nation’s industrial capacity is actually being used, ticked up to 76.2% in May. That figure remains 3.2 percentage points below the long-run average calculated from 1972 to 2025.

The broader economic context

The gradual recovery pattern since late 2025 is significant context here. After a period of sluggish or negative industrial output growth that plagued much of 2023 and parts of 2024, the manufacturing sector and its adjacent industries have been clawing back ground.

The Federal Reserve has its next annual revision to industrial production indexes scheduled for autumn 2026. Those revisions can sometimes meaningfully alter the trajectory that the monthly data initially painted, so the current numbers come with the usual asterisk that seasonal adjustments and benchmark revisions may shift the picture later.

What this means for investors

For equity markets, steady industrial production tends to support valuations in cyclical sectors like industrials, materials, and energy. The mining sector’s 1.3% gain is particularly relevant for commodity-linked investments.

The capacity utilization figure of 76.2% is perhaps the most important number for forward-looking investors. Sitting 3.2 percentage points below the long-run average, it suggests the economy can absorb additional demand without triggering supply-side inflation, giving the Federal Reserve more flexibility on the timing and pace of any future rate adjustments.
