The TACO Trade Meets a Shooting War

For the better part of two years, Wall Street had a thesis. It was elegant, profitable, and — as it turns out — wrong.

The thesis had a name: TACO. Trump Always Capitulates Online.

The TACO Framework

The logic was simple and, for a while, empirically supported. President Trump would make aggressive statements — about tariffs, about North Korea, about Iran — and markets would dip. Then, inevitably, he would find an off-ramp: a "beautiful deal," a "tremendous agreement," a tweet declaring victory. Markets would recover. Traders who bought the dip made money.

The TACO trade became so widespread that it was essentially consensus. Goldman Sachs published research noting that "geopolitical risk premiums associated with presidential rhetoric have a half-life of approximately 72 hours." JPMorgan's derivatives desk was selling volatility on every presidential tweet.

The Collision

On February 28, the TACO trade met its first real test: an actual shooting war.

In the first week, many traders held firm. "This is just another bluff," was the prevailing view on trading desks. The S&P dropped 4% and then stabilized as the market waited for the inevitable climb-down.

The climb-down didn't come.

By Day 7, with Hormuz closed and oil above $95, the TACO trade began to unwind violently. The VIX spiked to 26 — elevated but not panic. The real carnage was in sector rotation: airlines down 25%, cruise lines down 30%, while defense stocks and energy names surged.

The Current Picture

As of Day 25:

• •S&P 500: down 9.7% from pre-war levels
• •Nasdaq: down 12.3% (tech hardest hit by rising energy costs)
• •Dow: up 5.0% (energy/defense weighting helps)
• •VIX: 26.15 (sustained elevated volatility)
• •Dollar Index: 99.27 (surprisingly weak — flight from U.S. assets)

The most telling indicator may be the yield curve. The 10-year Treasury has collapsed to 0.43% — a level last seen during the COVID panic of 2020. Markets are pricing in severe economic disruption, if not outright recession.

What Comes Next

The TACO traders who survived are now asking a different question: not "when will Trump back down?" but "how bad can this get?"

The answer depends on Hormuz. If the strait reopens within 30 days, the economic damage is likely contained to a sharp but temporary growth shock. If it remains closed into summer, the compounding effects — inflation, consumer spending collapse, supply chain disruption — could trigger a recession.

Wall Street's new acronym has not yet emerged. But whatever replaces TACO will need to account for a possibility that the previous framework explicitly excluded: that sometimes, the brinkmanship is real.
