Tariffs are the only reason why the United States still has a steel industry of any size. China's excess capacity alone is sufficient to satisfy 100% of U.S. steel demand. If we let them, they would.
Free traders frequently set the bar for tariff effectiveness at whether they triggered a "boom" in the year or two after implementation. This is ridiculous, because the point of tariffs is to trigger a structural readjustment in demand that requires investment, construction, etc. over longer time horizons. The whole point is that you're building capacity that didn't previously exist. If it did, you wouldn't need tariffs.
The idea that previous tariff rounds settle the question is also ridiculous. Bush's 2001 steel tariffs were in effect for less than two years and exempted Canada and Mexico. Trump's 2017 steel tariffs quickly became Swiss cheese and exempted even more countries in even less time. Certainty is crucial, and if you can't provide it, there's a limit to how much new investment you can drive. The main forces blocking this certainty are free traders and importers who, in the past, have been able to kneecap tariff enforcement and then crow about how tariffs don't work. It's a shell game.
For a test of whether the current round of steel tariffs can drive new investment, see e.g. Mesabi Metallic's announcement yesterday of the largest investment in the history of American steel, which followed two other massive capital commitments (Hyundai and Nippon). Output is up across the sector, employment has held steady (a big win given what's happening in other countries) and new capacity coming online brings the price down. That's how it's always worked since the days of my favorite tariff "experiment," which is the creation of the American industrial base behind a 25-40% tariff wall during the Industrial Revolution.
"It is time to stop treating the outcome of tariff policy as a hypothetical. The experiment was run in 2001 and failed. It was re-run on a grand scale since 2017 and failed. It is not good economic policy. And in a month it will prove to be poor politics as well" 🔥
