A sweeping new wave of tariffs unveiled by President Donald Trump on Wednesday triggered a sharp selloff during the after hours of trading as the scope and scale of the trade duties exceeded Wall Street's worst-case expectations.

The president framed the move as a long-overdue correction to decades of trade imbalance, instituting what he called a "reciprocal tariff rate," set at 50% of what trading partners charge the United States, but also factoring in non-tariff barriers like currency manipulation, value-added taxes and outright import bans.

While Trump had telegraphed his intention to "rebalance" U.S. trade policy, the specific duty levels, some of which reached into the mid-30% range with key trading partners, jolted investors.

Under the new framework, China, which Trump said imposes tariffs as high as 67% on American goods, will now face reciprocal U.S. duties of approximately 37%. The European Union, which applies a 39% combined rate including VATs, will be subject to a 20% U.S. tariff. Japan, with an estimated 46% trade barrier, now faces a 24% duty on exports to the U.S.

Canada and Mexico, two major trading partners, were notably excluded from the tariff program — a move that suggests Trump may be preserving the U.S.-Mexico-Canada Agreement, at least for now.

The White House confirmed that new trade tariffs will take effect on April 9.
