The March 2026 US headline CPI (year-over-year) will print at or above 3.2% when released during the week of April 7–11, 2026, driven by tariff pass-through in goods categories and embedded energy cost from the pre-ceasefire Iran-Hormuz disruption.

Evidence for (6)
- Institutional contract-expiry cycle (3–9 months) places March 2026 squarely in the peak pass-through window for late-2025 tariff escalation — the most mechanistically specific timing argument
- Oligopolistic coordination via earnings-call signaling resolves collective action in concentrated goods sectors, compressing and synchronizing pass-through
- Iran/Hormuz risk premium was embedded in March energy prices, adding upward headline pressure that the April 7 ceasefire cannot retroactively erase
- Near-complete tariff incidence on US consumers confirmed empirically in 2018–2019 (Amiti, Redding, Zorn): foreign exporters absorbed negligible cost; domestic consumers bore full pass-through
- Attenuated labor bargaining power removes the principal demand-suppression mechanism that would otherwise flatten goods inflation
- Import price indices from January–February 2026 likely show leading acceleration that should flow into March CPI with standard 4–6 week retail lag
Evidence against (6)
- Pre-tariff inventory front-loading in Q4 2025 and early Q1 2026 creates a sell-down buffer that delays retail price adjustment into Q2
- Entrepreneurial margin absorption under competitive pressure suppresses immediate pass-through in import-dependent categories
- Animal spirits collapse under tariff uncertainty may suppress demand validation firms need to sustain full mark-up pass-through
- Oil price slide following the Iran-US ceasefire announcement could retroactively depress the energy component if intra-month readings average lower than end-March spike
- BLS hedonic adjustment and geometric-mean aggregation systematically compress sticker-price goods inflation by 15–30%, creating a structural wedge between tariff magnitude and CPI print
- Services and shelter dominate the CPI basket — goods-sector pass-through must be very strong to move headline YoY above 3.2% if shelter/services hold near prior levels
Reasoning chain
Two frameworks predict above-threshold (Marxist at 0.62, Institutionalist at 0.61); two predict below (Austrian at 0.56, Keynesian at 0.48). The institutionalist framework receives highest weight because it provides the most mechanistically specific timing argument: contract-expiry cycles place March 2026 in the peak pass-through window for tariffs imposed 4–6 months prior. The Marxist framework reinforces this with the oligopolistic markup-amplification mechanism and argues the demand-suppression channel is structurally attenuated. The Austrian and Keynesian counterarguments — inventory buffering, margin absorption, demand uncertainty drag — are real but may have already run their course by March given the tariff timeline. The Iran energy premium is embedded in March regardless of April ceasefire. Applying framework-weighted probability: (0.35×0.61) + (0.30×0.62) + (0.20×0.44) + (0.15×0.52) = 0.565, adjusted marginally upward from base rate of 0.45 to 0.57 reflecting the institutionalist timing specificity and energy embedding.
Philosophical basis
Institutionalist framework grounds the core timing mechanism — tariff pass-through is an institutional sequence, not a market event, and BLS methodology is itself an institution with systematic compressive effects. Marxist framework provides the structural reinforcement that pass-through in concentrated industries is near-complete. Austrian and Keynesian frameworks are given subordinate but non-negligible weight as genuine countervailing mechanisms (inventory buffering, demand-uncertainty drag) that constrain confidence well below certainty.
Falsification criteria
The prediction is falsified if the BLS March 2026 CPI release shows a headline YoY figure below 3.2%. It is confirmed if the YoY print is ≥3.2%. The April 7 Iran ceasefire announcement is irrelevant to falsification — it post-dates the March measurement window.

Brier breakdown
Post-mortem
Auto-resolved (confirmed, confidence=0.97). Evidence: The BLS released the March 2026 CPI report on April 10, 2026. Headline CPI rose 3.3% year-over-year (not seasonally adjusted), driven primarily by a 10.9% surge in energy costs — gasoline up 21.2% YoY — consistent with the Iran-Hormuz disruption cited in the prediction. Core CPI (ex food and energy) was 2.6% YoY. Multiple sources including CNBC, Fox Business, and the BLS release itself confirm the 3.3% print. Sources: https://www.cnbc.com/2026/04/10/cpi-inflation-report-march-2026.html; https://www.foxbusiness.com/economy/cpi-inflation-march-2026; https://www.bls.gov/news.release/pdf/cpi.pdf. Reasoning: The falsification criteria required a headline YoY print ≥3.2% for confirmation. The BLS March 2026 CPI release shows 3.3% YoY, which exceeds the 3.2% threshold. The prediction is therefore confirmed. The energy cost surge (gasoline +21.2% YoY) aligns with the Iran-Hormuz disruption mechanism cited in the prediction, providing mechanistic consistency in addition to the numerical confirmation.
