Energy, tariffs, and fertilizer are three independent inflation channels, sequential and non-overlapping. The consensus is focused on the energy wave that already peaked. The tariff wave is arriving. The food wave hasn’t started.
The March 2026 CPI print (3.3% headline, 2.6% core) was widely read as the Iran war’s inflation peak. Gasoline +21.2% month-over-month accounted for roughly 75% of the total March increase. The ceasefire brought oil down ~15% from the high. Conventional narrative: inflation resolves as the war deescalates.
That narrative is correct about Wave 1. It is blind to Waves 2 and 3.
The agriculture signal was found by accident. WEAT is −4.6% over the past month. The obvious read: food inflation isn’t a concern. The correct read: grain futures are a lagging indicator for consumer food prices by 4–6 months. The true leading indicator is fertilizer cost, which is locked in when farmers plant.
The CF/MOS split is surgical: it isolates the Hormuz effect perfectly. Nitrogen fertilizer (CF) is produced from natural gas, and LPG/LNG routes through Hormuz are disrupted. Potash (MOS) comes from Canadian/Russian mines and has no Hormuz exposure. CF +67.5% vs MOS −6.8% over 12 months is the market precisely pricing the supply chain disruption, not general ag inflation.
The 2026 spring crop is being planted this month at $720/ton urea. That cost structure does not show up in BLS food data until Q4 2026 at the earliest. The food-at-home CPI component, currently dragged down by the egg price crash (−44.7% YoY), will face the opposite dynamic in the fall as fertilizer costs transmit into crop yields and import prices.
Wave 3 arrives in Q4 2026, exactly when the market would normally begin pricing in Fed easing as tariff passthrough peaks. The food CPI component will be accelerating in Q4 as Wave 3 transmits. The Fed will be watching inflation re-accelerate in the one component most visible to voters just as they expected to cut.
The tariff passthrough signal is already in the data, but the data is forward, not backward. The BLS hasn’t captured it yet because importers are burning down inventory imported before April tariffs. That inventory runway: 8-12 weeks, based on typical retail cycle times. By late Q2, shelves start refilling with post-tariff inventory.
The IEEPA Supreme Court ruling converted broad reciprocal tariffs to a 10% flat baseline through July 24, with electronics explicitly exempt. This delays Wave 2 passthrough by 2-3 months. It does not cancel it. Commerce Secretary confirmed sector-specific semiconductor tariffs are coming “in a month or two.” The delay is the window between now and September where the consensus misreads the exemption as a structural disinflation and prices in rate cuts prematurely.
Separately from the inflation picture, three independent sources now confirm that goods throughput is entering a hard landing in Q2 2026:
These are not the same measurement. Cass tracks payment flows. BNSF tracks physical car movements at West Coast ports specifically (US-China import compression). DG equity tracks forward margin guidance from the lower-income consumer cohort. Container data tracks global trade volumes. The combination of all four pointing the same direction within the same quarter is four-sigma confirmation, not noise.
If the three-wave thesis is correct and Q2-Q3 2026 is the stress inflection, the defensive positioning question becomes: where do you own? The most asymmetric answer: BRK-B, which is currently at negative enterprise value.
$373B Berkshire cash pile exceeds the implied value of all operating businesses (BNSF, GEICO, BHE, See’s, the entire equity portfolio) at current market cap. The market is pricing BRK as “cash + zero optionality.” That discount exists because: the Buffett transition creates a management premium haircut; the cash drag penalizes BRK in a 2025 bull market; BNSF carloads are down −10%.
All three of those headwinds are features, not bugs, for a Q2 2026 stress scenario. The cash generates T-bill returns. The transition discount normalizes as Abel demonstrates his capital allocation thesis. BNSF’s carload weakness is already in the stock. And the $373B acquisition war chest is maximally valuable exactly when distressed assets become available, which the private credit gating chain ($4.6B trapped in Q1, Goldman at 4.999% threshold) suggests will happen in Q2-Q3.
Abel insider-purchased $15M of Class A shares at current prices. The management team is buying the same thesis.
STIP long: The three-wave framework extends the inflation accrual thesis well into Q4 2026. Even if the Fed manages to cut in late 2026 after Wave 2 peaks, Wave 3 (food CPI from $720 urea) arrives in the cut window. STIP protects against both.
TLT short: Confirmed by the Treasury auction data (30Y indirect −8pp, weakest BTC in dataset) and by the wave sequencing. The Fed is not cutting until well into H2, and fiscal supply dominates duration at every auction. The steepener (long 2Y, short 30Y) is cleaner than outright short.
CF Industries: Already +67.5% 1y, and most of the nitrogen shock is priced. The incremental catalyst is whether Hormuz normalization fails before mid-May. If it does, CF’s Q2 guidance at the May earnings call confirms another leg. If it doesn’t, the thesis is priced.
BRK-B: The defensive position for the Q2 stress scenario. Cash + free optionality on distressed acquisitions + BNSF carload recovery in H2 if tariff regime clarifies. Abel insider buy at current prices is the signal.
ALB: Lithium cycle turn confirmed (ESS +51% YoY, 2026 supply deficit consensus, Rio Tinto buying at trough). 82% tariffs on Chinese batteries create a structural US sourcing shift toward ALB. Q1 earnings May 6 tests whether gross margins are recovering above 18%. Below 18%: dead-cat bounce. Above 18%: the cycle is real.
