TACO trade losing power as Trump’s brinkmanship fails to sway markets

Markets on Wall Street have recently signaled that the so-called "TACO" trade — shorthand for "Trump Always Chickens Out" — is losing its former potency. Major US indices slid to multi-month lows as investors showed less inclination to reflexively price in White House rhetoric and more focus on tangible developments.

The sequence of events combined political rhetoric, tactical reversals and commodity price moves. On March 27, 2026, the S&P 500 fell about 0.8% to 6,425 points while the Nasdaq dropped roughly 1%; the Dow closed down 1.7% (around 792 points) at 45,167, entering official correction territory. Those moves followed the president’s decision to extend a pause on strikes related to the Iran conflict, a step that some traders interpreted as another "TACO" moment but which this time failed to trigger a sustained equity rebound.

The market backdrop mattered: Brent crude climbed above $110 a barrel, tightening the inflation outlook and pressuring real yields. Energy-driven risk repricing limited the carry-through from any short-lived risk-on bursts and reinforced caution among portfolio managers. Where earlier tariff threats had routinely produced sharp sell-offs followed by dip-buying, the interplay between higher commodity prices and geopolitical uncertainty has dulled that pattern.

The label "TACO" was popularized by Financial Times columnist Robert Armstrong to describe investors’ tendency to buy the dip after tariff threats and subsequent reversals; major outlets including Bloomberg and others documented how the acronym migrated into trader vernacular. But market participants and strategists now warn that the once-reliable reflex of buying on presidential backtracks may be less effective when other macro and geopolitical forces dominate.

Looking ahead, analysts expect higher short-term volatility as investors demand more concrete signals before re-entering risk assets. Some strategists argue that if energy prices and wider risk premia remain elevated, TACO-style dip-buying could produce more losses than gains. Asset managers will likely prioritize liquidity and scenario planning, while trading desks monitor whether future policy threats are followed by decisive action or further reversals — either outcome will reshape how markets price political risk going forward.
