Wall Street is taking President Donald Trump’s latest threat on tariffs in stride, on the whole, and U.S. stocks are drifting higher on Monday. The S&P 500 was up 0.6% in midday trading, coming off a losing week that was bookended by worries about how potential tariffs could push up inflation and threaten the economy.

Steel and aluminum are heavily used in the automotive and construction industry, but are also used to manufacture goods and appliances. The decision mirrors the actions Trump levied during his first Administration, when he enacted a 25% tariff on steel and 10% tariff on aluminum, though some countries, including South Korea were exempt.
