On Wall Street, traders have a new mantra: When Trump threatens tariffs, reach for a TACO. No, not the crunchy kind. The acronym, which stands for "Trump Always Chickens Out," is the latest buzzword among traders and investors navigating months of economic whiplash caused by the US President's ever-changing trade stances. Coined by Financial Times writer Robert Armstrong, TACO is a label for what has become a familiar pattern: Trump announces sweeping tariff threats, markets react with a downturn, investor anxiety intensifies, and then, almost predictably, he reverses course, triggering a relief rally. "I chicken out? Oh, I've never heard that. You mean because I reduced China from 145 per cent that I set down to 100 and then to another number?" Trump said Wednesday when asked about the term. He made the remarks at an Oval Office event when he referred to his shifting tariff rates on imported Chinese goods, a cycle that has seen peaks as high as 145 per cent before dialling back to the current 30 per cent.
