WASHINGTON, April 9, (AP): By declaring a trade war on the rest of the world, President Donald Trump has panicked global financial markets, raised the risk of a recession and broken the political and economic alliances that made much of the world stable for business after World War II. Trump's latest round of tariffs went into full effect at midnight Wednesday, with higher import tax rates on dozens of countries and territories taking hold.

Economists are puzzled to see Trump trying to overhaul the existing economic order and doing it so soon after inheriting the strongest economy in the world. Many of the trading partners he accuses of ripping off US businesses and workers were already floundering. "There is a deep irony in Trump claiming unfair treatment of the American economy at a time when it was growing robustly while every other major economy had stalled or was losing growth momentum,” said Eswar Prasad, professor of trade policy at Cornell University.

"In an even greater irony, the Trump tariffs are likely to end America’s remarkable run of success and crash the economy, job growth and financial markets.’’ Trump and his trade advisers insist that the rules governing global commerce put the United States at a distinct disadvantage. But mainstream economists - whose views Trump and his advisers disdain - say the president has a warped idea of world trade, especially a preoccupation with trade deficits, which they say do nothing to impede growth.

The administration accuses other countries of erecting unfair trade barriers to keep out American exports and using underhanded tactics to promote their own. In Trump’s telling, his tariffs are a long-overdue reckoning: The US is the victim of an economic mugging by Europe, China, Mexico, Japan and even Canada. It's true that some countries charge higher taxes on imports than the United States does. Some manipulate their currencies lower to ensure that their goods are price-competitive in international markets. Some governments lavish their industries with subsidies to give them an edge.

However, the United States is still the second-largest exporter in the world, after China. The US exported $3.1 trillion of goods and services in 2023, far ahead of third-place Germany at $2 trillion. The fear that Trump’s remedies are deadlier than the maladies he’s trying to cure has sent investors fleeing American stocks. Since Trump announced sweeping import taxes on April 2, the S&P 500 has cratered 12%.
