The verdict

What if Suez closes to wheat?

For this scenario, Suez stays closed for 30 days. About 97% of the measured lane flows through it, so roughly 29.1 lane-days of shipments are delayed — delayed, not destroyed: the cargo still exists, it just arrives late.

In the recorded Black Sea, 2022 analog, wheat futures rise +62.7% in 12 days (23 Feb 2022 → 7 Mar 2022), and for consumers: retail bread (US) rose +7.2% to +11.3% over 4–6 months. Illustrative — what happened then, not what will happen now.

Delayed ≠ lost. Illustrative scenario. Not a prediction. Not financial advice.

Guided scenario

What if Suez closes to wheat?

On the measured lane, 97% of Black Sea/EU wheat to Asia transits Suez. Model the delay.

1The setup

On the measured lane — European, Russian, and Ukrainian wheat shipments to selected Asian countries and Eastern Africa — 97% transits the Suez Canal (WTO Wheat Dashboard, pre-crisis baseline). A closure doesn't destroy grain; it stops the clock. This guide walks through what the monitor is seeing right now, how the lane works, and lets you model a closure yourself.

2Adjust the assumptions

30d

Historical check: The closest episode, Black Sea, 2022, lasted 148 days (medium); your 30-day canal closure sits in the medium band.

How long the lane stays closed. Duration changes the timeline — never the flow share.

Resolution: Days the lane stays closed or throttled

What this assumes
  • Canal closure — 30 days × 97% of the lane = lane-days disrupted. Duration changes the timeline, never the flow share.
  • Delayed ≠ lost: the cargo still exists — only its arrival is late.
  • Share of EU/Russia/Ukraine wheat shipments to selected Asian countries and Eastern Africa transiting Suez, pre-crisis baseline (WTO Wheat Dashboard). Disclosed scope — not all RU+UA exports.
  • Illustrative arithmetic from your stated assumptions — not a price forecast.

29.1

lane-days disrupted

30d × 97% of the lane via Suez

What the delay looks like

A shipment that would have transited Suez on day one waits roughly the full 30 days. Rerouting avoids the queue at the cost of a longer voyage. Either way the shipment is delayed, not destroyed.

Delayed ≠ lost — the disruption stops the clock on shipments; it doesn't destroy wheat.

What this would have meant

For this scenario, Suez stays closed for 30 days. About 97% of the measured lane flows through it, so roughly 29.1 lane-days of shipments are delayed — delayed, not destroyed: the cargo still exists, it just arrives late.

In the recorded Black Sea, 2022 analog, wheat futures rise +62.7% in 12 days (23 Feb 2022 → 7 Mar 2022), and for consumers: retail bread (US) rose +7.2% to +11.3% over 4–6 months. Illustrative — what happened then, not what will happen now.

Analog check

Your settings look closest to Black Sea, 2022 (same commodity, same shock type, similar size, similar duration, similar supply concentration). The episode's measured moves, caveats included: wheat futures +62.7% in 12 days (23 Feb 2022 → 7 Mar 2022); Retail bread (US): +7.2% to +11.3% over 4–6 months. 2022's bread move also reflects soaring natural-gas and diesel costs (fertilizer and freight) and broad post-pandemic food inflation — not all of it traces to the wheat shock..

Only about 11.8¢ of every US consumer food dollar — and 18.5¢ of every food-at-home dollar — reaches the farm (USDA, 2024) — that's a ceiling, not a prediction: margins can absorb a spike or amplify it.

Illustrative — what happened then, not what will happen now. Your scenario differs: your scenario is a hypothetical — the episode is history, and its prices moved with the whole economy (energy, freight, demand), not just this shock.

The record holds no lane-closure episode: this match is against past wheat shock episodes, while the delay itself is sized from your settings above — not from history.

How we matched this
  • Commodity: requirement — Both are wheat — non-wheat episodes are excluded outright.
  • Shock type: 2/2 — Both are a conflict shock.
  • Size: 1/1 — Your 100% disruption setting band: extreme; episode futures moved +62.7% (23 Feb 2022 → 7 Mar 2022) — band: extreme. Severity is % of shipments disrupted, not a price move: this banding is a v1 matching heuristic.
  • Duration: 1/1 — Your disruption: 30-day (medium); episode: 148-day (medium) — Ukrainian commercial shipping suspended 24 Feb 2022; Black Sea Grain Initiative signed 22 Jul 2022 (repo event records russia-ukraine-war, bsgi-exit-2023).
  • Supply concentration: 1/1 — Your hazard zone: 24.1% of world exports (moderate); episode disrupted ~30% (moderate) — Russia and Ukraine together were about three-tenths of world wheat exports (Reuters, Mar 2022 — repo event record russia-ukraine-war).

Score 5/5 — close analog (headline).

How we map this

Exporter and importer shares are 2024 vintage · annual data, 1–2y lag from UN Comtrade and OEC (BACI/CEPII); an importer counts as exposed when ≥20% of its wheat imports come from a shocked exporter. The shock geography is the scenario’s own focus selection. Annual data with a 1–2 year reporting lag — the structure moves slowly, the prices don’t.

5What happened before

For perspective, not prediction

Ever Given blocks the Suez Canal (March 2021)

Mar 23 – Mar 29, 2021

“The Ever Given blockage delayed shipping for six days. This record contains contemporary oil reporting but no verified agricultural event-window price comparison; it cannot establish the absence of an agricultural price effect.”

Price moves were observed around the event — not proof the event caused the entire move.

Red Sea / Houthi shipping disruption (2023–24)

Nov 2023 – Apr 2024

“During Nov 2023 to Apr 2024, Chicago wheat futures rose slightly while corn and soybeans fell, alongside Red Sea shipping disruption. These benchmarks do not measure freight or delivered import costs, and their net changes cannot establish that the disruption had no commodity-price effect.”

Price moves were observed around the event — not proof the event caused the entire move.

Russia invades Ukraine: the Black Sea grain and fertilizer shock

Feb 2022 –

“Chicago SRW wheat futures rose early in 2022 and later gave back part of that rise. The Black Sea disruption and subsequent changes in trade and supply are documented, but these price windows do not isolate the war’s effect or show where prices would have been without it.”
