Trump's Tariff Threats: 75% Are Just Talk, Study Finds

US President Donald Trump has made four major tariff threats in recent weeks. These warnings targeted Iran's partners, Greenland's supporters, Canada, and South Korea. Typically, such threats would alarm investors and business leaders. Economists would quickly change their growth forecasts for the affected countries. But markets and executives have largely ignored these latest warnings. A new study explains this reaction. Researchers found that President Trump only follows through on about one in four of his tariff threats. The analysis, nicknamed the "TACO" study, suggests markets now see most threats as just words. The warnings are viewed as tools to gain leverage or force a change in behavior, not as promises of immediate action. This pattern means the financial impact of a threat is often muted until it becomes a firm policy.
