AIS・FAO食料価格・運賃先物データを用い、2026年ホルムズ海峡危機の影響を局所射影法とIMO GHG会計で分析。海峡通航は最大95.1%減、陸路迂回はトンキロ費用2.4〜4.2倍・CO2 1.47〜3.54倍に増加。しかし食料価格への影響は統計的にゼロと区別できず、レジリエンスと脱炭素のトレードオフをSDGs 2・12の観点から示す。
English
Using AIS, FAO food prices, and freight futures, the study assesses the 2026 Strait of Hormuz disruption via local projections and IMO GHG accounting. Hormuz transits fell up to 95.1%, and overland rerouting raised ton-km costs 2.4-4.2x and CO2 1.47-3.54x. Food price effects were statistically indistinguishable from zero, highlighting a resilience-decarbonization trade-off under SDGs 2 and 12.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は食料・エネルギーの多くを海上輸送に依存し、ホルムズ海峡は中東産原油の主要ルート。有事の迂回がCO2とコストを押し上げる構図は、日本のエネルギー安全保障とGX物流戦略の両面で示唆を持つ。
In the global GX context
Chokepoint disruptions and multimodal rerouting directly affect Scope 3 transport emissions and freight costs, relevant to TCFD/ISSB supply-chain risk disclosure and transition planning for import-dependent economies.
👥 読者別の含意
🔬研究者:チョークポイント混乱の価格伝播とGHG会計を統合した実証枠組みを提供する。
🏢実務担当者:有事の物流迂回がコストとScope 3排出を同時に押し上げる点を調達・開示計画に反映すべき。
🏛政策担当者:食料・エネルギー輸入国はレジリエンス強化と脱炭素のトレードオフを政策設計に織り込む必要がある。
📄 Abstract(原文)
Maritime shipping carries over 80% of global merchandise trade, making strategic chokepoints critical for food-importing regions. The 2026 Strait of Hormuz crisis triggered an acute shipping disruption threatening Persian Gulf food import corridors. Combining daily AIS data across 28 chokepoints with monthly FAO food prices and freight futures (2019–2026), we apply local projections and IMO GHG accounting. Daily Hormuz transits fell 95.1% during the March–May 2026 peak, with dry bulk transits down 88.8%. However, local projection impulse responses indicate that food price impacts remain statistically indistinguishable from zero (all p > 0.05), with 57.5% of historical placebo estimates matching or exceeding the actual estimate in absolute value. Because the crisis occurs late in the sample, direct evaluation is limited to horizons h = 0 to 3. Multimodal scenarios show overland rerouting increased ton–kilometer costs 2.4- to 4.2-fold and CO2 emissions 1.47- to 3.54-fold, yet overland door-to-door costs were lower than direct shipping with war-risk surcharges. These findings suggest that crisis transmission cannot be statistically distinguished from background volatility under available data, exposing a trade-off between resilience and decarbonization for import-dependent regions under Sustainable Development Goals (SDGs) 2 and 12.
