Evidence for (8)
- Tariff pass-through second wave: supply chain repricing and contract renegotiations from 2025 tariff architecture reaching consumer prices in Q1 2026 (documented 3-9 month lag)
- Red Sea/Suez and Hormuz disruptions: shipping cost inflation from Q4 2025 maritime interdiction flowing into goods CPI with 2-4 month lag, squarely landing in March reading
- OER measurement convention lag (BLS institutional design): owners' equivalent rent reflects 2024-2025 market rent conditions, sustaining services inflation component above trend
- Price-setting norm inertia: firms re-anchored to elevated base levels with high switching costs; collective action failure prevents coordinated disinflation absent demand destruction
- Endogenous money ratification: banks accommodating working capital demand at elevated inventory costs, monetizing cost-push rather than constraining it
- Soft base effect: if March 2025 YoY was relatively subdued, the arithmetic comparison favors a higher 2026 reading
- Energy rent extraction: US-Iran standoff and Houthi Bab al-Mandeb threat keep energy markets in volatile holding pattern, feeding directly into headline CPI energy component
- All four frameworks independently predict at-or-above 3.5%, a rare cross-paradigm consensus
Evidence against (7)
- Dollar strength during Iran crisis (flight to safety) compresses import prices, partially offsetting tariff channel
- Consumer credit tightening could trigger demand destruction faster than stable consumption function implies, compressing markup margins
- Tariff enforcement may be softer in practice than legal form — importers absorbing margin compression to preserve market share rather than passing costs forward
- Fed credibility institution may suppress price-setting expectations if rhetoric is sufficiently aggressive, changing actual pricing behavior faster than structural models predict
- Commercial real estate and rate-sensitive sector malinvestment correction could produce deflationary offset in goods/asset-adjacent services
- Seasonal adjustment factors for March introduce mechanical noise that no framework modeled — could move the print either direction
- Precautionary saving surge (geopolitical uncertainty) could reduce consumption faster than the asymmetric animal-spirits model assumes
Reasoning chain
Four independent frameworks applied to the same question converge on the same directional prediction — a rare signal. The base rate for headline CPI ≥3.5% in this phase of the cycle (post-inflation-peak, active supply-side shock, tariff regime installed) is estimated at 0.48, reflecting genuine uncertainty about whether disinflation resumes or stalls. The framework consensus upgrades this: each framework identifies distinct transmission mechanisms (extraction circuits, Cantillon effects, Kaleckian markup pricing, OER institutional lag) that are simultaneously active in Q1 2026. No single mechanism is decisive; their coincidence in the March reading is what drives the upgrade. The residual uncertainty — reflected in confidence capped at 0.63 rather than higher — stems from: (1) the 3.5% threshold being precise while structural analysis is directional; (2) dollar-strength and demand-destruction countervailing channels that all frameworks acknowledge; and (3) the BLS seasonal adjustment being a mechanical wildcard unmodeled by any framework. The institutionalist framework received lower weight because its individual confidence was lowest (0.58) and it contributed less unique mechanism beyond what tariff pass-through and norm inertia already captured in other analyses; however, its OER lag insight is a genuine institutional-design mechanism not fully captured elsewhere.
Philosophical basis
All four frameworks contribute but on distinct explanatory terrain. Marxist analysis grounds the tariff-as-extraction-seigniorage mechanism and identifies measurement suppression as a systematic feature rather than error. Austrian analysis provides the monetary-overhang and Cantillon-effect temporal structure — the residual price revelation from 2020-2022 credit expansion still propagating through slow-adjusting contracts. Keynesian analysis supplies the Kaleckian markup pricing model under simultaneous cost shock, and the endogenous money ratification channel that prevents credit contraction from strangling cost-push. Institutionalist analysis provides the OER measurement-convention argument and the collective action failure in disinflation — the most concrete mechanism for why price-setting norms are path-dependent above 3%. The convergence across paradigms that differ sharply in ontology (class conflict, spontaneous order, aggregate demand, institutional path dependence) constitutes the prediction's strongest epistemological foundation.
Falsification criteria
BLS release of March 2026 CPI data (scheduled ~April 10, 2026) shows headline CPI YoY below 3.5%. Any official BLS revision published before April 21 that confirms a sub-3.5% reading also falsifies the claim.

Brier breakdown
Post-mortem
Auto-resolved (falsified, confidence=0.97). Evidence: The BLS released March 2026 CPI data on April 10, 2026. Headline CPI came in at 3.3% year-over-year — below the 3.5% threshold specified in the prediction. Multiple sources confirm this figure: the official BLS release, CNBC, and Advisor Perspectives all report 3.3% YoY. Sources: https://www.bls.gov/news.release/archives/cpi_04102026.htm; https://www.cnbc.com/2026/04/10/cpi-inflation-report-march-2026.html; https://www.bls.gov/opub/ted/2026/consumer-prices-up-3-3-percent-over-the-year-0-9-percent-over-the-month-in-march-2026.htm. Reasoning: The falsification criteria states: 'BLS release of March 2026 CPI data shows headline CPI YoY below 3.5% falsifies the claim.' The BLS released on April 10, 2026 showing headline CPI at 3.3% YoY, which is clearly below 3.5%. The prediction is therefore falsified. Note that while 3.3% is significantly elevated (up from February's 2.4%), it still falls short of the 3.5% threshold required for confirmation.
