Following a minor dip in mid-June, raw steel production rose last week to a new multi-year high, according to the latest data released by the American Iron and Steel Institute (AISI). US mills have ramped up production since April, with weekly output steadily increasing in nearly every week since.
Domestic steel mills produced an estimated 1,787,000 short tons (st) of raw steel through the week ending June 21 (Figure 1). Output grew by 4,000 tons, or 0.2%, compared to the prior week, now at the highest unadjusted weekly figure recorded since May 2022.
Last week’s production was 5.5% above the year-to-date (YTD) average of 1,694,000 st per week and 4.9% higher than the same week the previous year.
The mill capability utilization rate was 79.6% last week, up from both the prior week (79.4%) and one year ago (76.7%).
YTD production now stands at 41,642,000 st with a capability utilization rate of 75.8%. Mills have produced 0.2% more steel this year than the same period of 2024. Before June, steel output in 2025 had been running behind 2024 levels.
Raw production increased week over week (w/w) in three of the five AISI-defined regions:
- Northeast – 120,000 st (down 9,000 st w/w)
- Great Lakes – 564,000 st (up 8,000 st)
- Midwest – 248,000 st (down 5,000 st)
- South – 786,000 st (up 6,000 st)
- West – 69,000 st (up 4,000 st)
Editor’s note: The raw steel production tonnage provided in this report is estimated and should be used primarily to assess production trends.

Service centers: Mill orders down marginally in May
SMU’s Mill Order Index (MOI) declined for a third straight month in May, but only marginally.
Final Thoughts
Not many people in the North American steel market had direct US involvement in another Middle East conflict on their bingo card. Prices weren't expected to shoot higher unless something unexpected happened. That unexpected something has now happened. And there is talk of oil at $100 per barrel. What does that mean for steel?
SMU Community Chat: Wednesday With AGC Chief Economist Ken Simonson
We’ll have a lot to talk about because construction is at the intersection of so many of today’s hot-button issues. The main question: Will construction thrive or dive in the rest of ’25? (Nothing wrong with a rhyme, even in serious times.)
Price: Is It Nippon Steel USA or a partnership? And what does that mean for imports?
The document makes clear that Nippon Steel, through Nippon Steel America, will have “100% ownership of [the] common stock.” So if you want to own an interest in U.S. Steel’s future success, you will need to buy shares in Nippon Steel on the Nikkei stock exchange. It certainly will not be in your domestic S&P 500 ETF.
