Tariff Threats, Follow-Through, and the PEPIndex Behind the Concept
TACO stands for Trump Always Chickens Out. The TACO Index is a colloquial name for a measurable pattern: presidential economic threats — tariff announcements, trade ultimatums, sanction deadlines — are made with high confidence and then partially or fully reversed before full implementation.
The concept gained traction as a way to describe the recurring gap between announced policy (e.g., "145% tariff on China") and what was actually applied at the border (e.g., 28% after exemptions and reversals). That gap is not an accident — it is the quantifiable signature of policy pressure used as a negotiating tactic rather than a firm commitment.
When a 145% tariff is announced on Chinese goods, markets react, negotiations begin, and exemptions accumulate. By the time the tariff is actually collected, the effective applied rate — measured by USITC DataWeb as duties collected divided by customs value — is often a fraction of the headline rate.
This statutory-vs-applied gap is not a side effect: it is the core signal. The gap represents the degree to which a threat was a bluff, a negotiating position, or a genuine policy commitment.
| Event | Announced rate | Applied rate | Gap | PEPIndex score |
|---|---|---|---|---|
| Liberation Day: China | 145% | ~28% | 117pp | 82.1 |
| 14-Country Deadline | 25% | ~11.6% | 13.4pp | 60.5 |
| Section 301 China / Phase One | 25% avg | ~12.5% | ~12.5pp | 53.0 |
| Section 232 Steel/Al | 25% | ~14% (post-exemptions) | ~11pp | 34.0 |
The TACO name is memorable and accurate, but it is not the right frame for analysts, supply-chain teams, and data teams that need to embed trade-policy risk into models, dashboards, and procurement workflows.
PEPIndex (Presidential Economic Pressure Index) is the quantitative instrument:
| User type | What they get from PEPI |
|---|---|
| Trade-policy analysts | Daily pressure score with event provenance and statutory authority |
| Supply-chain strategy teams | Early warning before tariff exposure hits procurement costs |
| Procurement / sourcing teams | Sector-level tariff risk before supplier renegotiation |
| Market-risk / macro analysts | Structured daily policy-risk factor for macro models |
| Data teams at logistics platforms | API-ready tariff pressure layer |
