American steelmakers will most likely be able to charge higher prices as demand for domestic sources of metal increases. But the broader economy is likely to suffer.

One of America’s most storied industries is getting a massive boost from Donald Trump’s latest tariffs push — at the potential cost of a broader slowdown elsewhere in the U.S. economy.

Trump signed an executive order increasing the already substantial 25% duties on steel imports he first set in March to 50%. He signaled last week that the tariff rate hike was coming. It went into effect at midnight Wednesday.

A study found that while Trump’s 2018 steel tariffs created 1,000 new direct jobs, it cost downstream industries that rely on steel to make their products as many as 75,000 jobs because they became less competitive thanks to higher costs.

While some limited capacity could come back online in the near term, the on-again, off-again nature of the tariffs limit any immediate job gains, said Josh Spoores, head of Steel Americas Analysis at the CRU Group consultancy.
