JPMorgan Builds a TACO Index to Predict Trump's Tariff Moves

JPMorgan has built a TACO index — a barometer designed to predict when President Donald Trump will back down on tariff threats — and the bank's own indicator now signals it is time for the White House to strike a deal.

The acronym TACO stands for "Trump Always Chickens Out," a phrase coined by traders to describe a recurring pattern in the president's negotiating behavior. The pattern is straightforward. Trump announces aggressive tariff measures. Markets sell off. The president then retreats, softens or delays the measures. Investors who anticipated the retreat buy the dip and profit.

JPMorgan has now formalized that market folklore into a quantitative tool. The bank has devised the TACO barometer as a way to predict the behavior of the mercurial world leader, according to a report on the index. In doing so, JPMorgan joins a broader effort on Wall Street to systematically forecast policy moves from an administration whose trade decisions have repeatedly moved global markets.

What the Index Does

The TACO index operates on a simple premise: Trump's tariff threats have, in many cases, not fully materialized. By tracking the gap between announced measures and implemented ones, the indicator attempts to quantify the probability that a given threat will ultimately be withdrawn or diluted.

The phrase "Trump Always Chickens Out" gained traction among investors earlier this year as the president's pattern of escalation followed by retreat became visible across multiple trade confrontations. Traders began treating sharp, tariff-driven selloffs as buying opportunities, on the theory that the White House would eventually climb down.

JPMorgan's contribution is to turn that behavioral thesis into a measurable gauge. The bank's read on the current moment, according to the report, is that the index is now flashing a signal: the conditions point toward the president striking a deal.

Why It Matters for Markets

The stakes are considerable. Tariff announcements under the current administration have triggered volatility across equities, currencies and bond markets. Investors who can anticipate a retreat before it happens hold a meaningful edge. Those who cannot have repeatedly sold at the bottom, only to watch markets recover once the White House softened its position.

The index also reflects a deeper shift in how financial institutions approach political risk. Traditional macro analysis treated trade policy as a slow-moving variable. Under Trump, it has become a fast, unpredictable driver of asset prices. Banks have responded by building tools that treat presidential behavior itself as a data set — one that can be tracked, modeled and, in theory, front-run.

There are limits to the approach. A behavioral index built on past retreats carries an obvious risk: the pattern holds only until the day it doesn't. If the president follows through on a tariff threat in full, positions calibrated to a TACO-style retreat would face sharp losses. The index's own logic acknowledges this asymmetry — its value lies in probability, not certainty.

The Current Signal

The report's central claim is timelier than the methodology. JPMorgan's TACO barometer is signaling that this is the moment for Trump to strike a deal — an indication that the bank sees the political and market conditions as aligned for a retreat from maximalist tariff positions.

For investors, the practical question is whether the pattern holds once more. If JPMorgan's gauge is right, the current trade standoff ends in negotiation rather than escalation, and markets pricing in the worst case would have room to recover. If the president breaks the pattern instead, the traders who coined the acronym will learn the cost of underestimating him.
