Macro Scenario Monitoring
Vol. 1 | Commodity branch
This branch focuses on energy and food as the first transmission layer of the U.S.-Iran war scenario. The desk question is not only whether prices move, but whether physical evidence, logistics, inventories, and policy action confirm a durable macro shock.
Desk question
What a sell-side macro desk needs from commodity analysis
Physical read
Is the shock real? The desk checks inventories, storage, exports, refinery runs, freight, crop conditions, acreage, and bottlenecks before treating the price move as fundamental.
Macro read
How does the shock pass into inflation, real income, trade balances, FX, and growth? This is where commodity analysis becomes macro economics.
Client read
What should clients do with this information? The desk writes what changed, what confirms it, what could invalidate it, and which countries or assets are exposed.
Scenario ladder
Vol. 1 commodity scenarios
Scenario A
Pre-war baseline
Commodity risk premium stays manageable. Oil and food prices reflect normal supply-demand conditions more than conflict escalation.
Scenario B
Current war shock
Oil, shipping, insurance, fertilizer, and food-security channels all move higher. The desk tests whether the physical data confirm the price move.
Scenario C
Post-war relief
Risk premia fade, logistics normalize, curves flatten back, and the inflation impulse weakens faster than the fear premium suggested.
Scenario D
Post-war fragmentation
Even after active conflict cools, sanctions, route shifts, and energy-security policy keep commodity premia and inflation risk structurally higher.
Decision model
How the commodity branch makes a call
| Layer | What the desk checks | Examples | Why it matters |
|---|---|---|---|
| Shock type | Classify the move as supply, demand, logistics, sanctions, weather, or policy. | War escalation, shipping disruption, export ban, drought, refinery outage. | Different shocks produce very different inflation and growth paths. |
| Physical confirmation | Check whether the market move is supported by actual balance evidence. | Inventories, storage, refinery runs, acreage, yield expectations, export flows. | This helps separate a durable shortage from a temporary fear premium. |
| Curve and spread confirmation | Watch futures structure and product spreads. | Brent time spreads, gasoline and diesel cracks, grain nearby-deferred spreads. | A tight front end often confirms real near-term scarcity. |
| Macro transmission | Map the commodity shock into inflation, income, trade, and policy. | Gasoline pass-through, fertilizer into food, importer/exporter FX stress. | This is the bridge from commodity market reading to macro forecast revision. |
| Desk output | Write what changed, what confirms it, and what would invalidate the call. | Client note, sales/trading brief, country-exposure table, inflation warning. | Sell-side research must explain the call, not only state the price move. |
Signals and indices
Main public reports and market series the branch should use
| Bucket | Signal or report | What it tells the desk | Cadence | Why it matters for the sell-side note |
|---|---|---|---|---|
| Oil | Brent, WTI, and crude time spreads | Spot direction, near-term tightness, and curve structure. | Daily | Separates a simple headline price move from a true shortage story. |
| Oil products | Gasoline and diesel cracks, retail gasoline | Refining tightness and direct pass-through into inflation. | Daily / weekly | Clients care about CPI transmission, not only crude itself. |
| Oil balance | EIA Weekly Petroleum Status Report, EIA STEO, IEA Oil Market Report, OPEC MOMR | Inventories, refinery runs, supply-demand balance, spare capacity, export changes. | Weekly / monthly | These reports anchor the fundamental read behind the price narrative. |
| Natural gas | Henry Hub, LNG exports, EIA storage report | Storage tightness, export pull, weather sensitivity, domestic balance. | Daily / weekly | Gas often matters through utilities, power, and LNG-linked global spillovers. |
| Positioning | CFTC Commitments of Traders | Whether price action is being amplified by speculative positioning. | Weekly | Helps explain overshoots and unstable reversals. |
| Grains | Corn, wheat, soy futures and nearby-deferred spreads | Food risk premium, weather sensitivity, and tightness at the front of the curve. | Daily | Links food shocks to inflation and importer stress. |
| Crop balance | USDA WASDE, Grain Stocks, Crop Progress, Export Sales | Production, stocks-to-use, crop condition, export demand, and shipment pace. | Weekly / monthly / quarterly | These are the core physical reports for a grain-based macro call. |
| Global food | FAO Food Price Index | Broad international food-price pressure. | Monthly | Useful when a sell-side note needs a global inflation and EM vulnerability angle. |
Best starting rule: treat a commodity shock as credible only when physical reports, curve structure, and macro transmission all point in the same direction.
