同時に封鎖された3つの動脈
価格高騰の背景にある供給の混乱は3つの要因からなり、それぞれが、かつて市場の緩衝材となっていた代替手段を奪っています。1 1つ目はホルムズ海峡です。通常、ここでは1日あたり約20 million barrels、世界で取引される海上輸送原油のおよそ4分の1が通過します。24 イランは海峡の閉鎖を宣言し、機雷を敷設して船舶を攻撃したため、通航は大きく制限されています。1 EIAのデータによると、2026年第2四半期の輸送量は開戦前の約21 million barrelsからわずか4.9 million barrels per dayへと急減し、衛星追跡を行う機関の中には、船舶の到着が開戦前の約4%にすぎないとするところもあります。1
場所
- 01ホルムズ海峡
- 02バブ・エル・マンデブ海峡
- 03ヤンブー、サウジアラビア
戦時下の数値にはつきものですが、数字には不確かさもあります。広く引用されている9月13日の数値はガソリンが4.29ドル、ディーゼルが6.05ドルですが、同日の別の調査ではやや高い数値が示され、ガソリンは4.31ドル、ディーゼルは6.20ドルとなっており、AAAは史上最高値を6.2040ドルとしています。1 EIAの9月7日終了週の週間調査では、レギュラーガソリンは4.16ドル、高速道路用ディーゼルは5.97ドルでした。その後、AAAの日次データは上昇を続けています。2931 また、ホルムズ海峡が海上輸送の4分の1を占めるとの推計が大半を占める一方、3分の1を超えるとする分析もあります。10
記録的なディーゼル価格の上昇
分かっていること
不明な点
- ディーゼル価格は6.05ドルと6.20ドルの数値が競合しており、9月13日の確定値はない。
- ディーゼル価格から食品価格への転嫁率を示す定量的な数値はなく、分かっているのは方向性と時間差だけ。
今後の展開
- ホルムズ海峡の輸送量が1日あたり4.9 million barrelsから回復するのか、戦闘の激化でさらに減るのか。
- 収穫期とホリデーシーズンの輸送コストが、食料品価格の新たな値上がりを招くのか。

放送時の内容
- Diesel fuel has hit an all-time national record of six dollars and five cents a gallon. That number is rewriting the cost of nearly everything Americans buy. Nearly three-quarters of commercial shipping runs on diesel, so the spike hits freight first, then producer prices, then shelves at the grocery store. How long does the surge hold? The answer depends on three chokepoints currently in a war zone.
- The national average for diesel is six dollars and five cents a gallon. That tops the previous record of roughly five dollars and eighty-two cents set in 2022, and it is up sharply from three dollars and seventy-five cents before the war began in late February.
- Regular gasoline averages four dollars and twenty-nine cents, up from two dollars and ninety-eight. It remains below its 2022 record of five dollars and two cents, but diesel is where the true pressure sits.
- Diesel is the workhorse fuel behind the trucks that carry nearly everything Americans buy, plus rail, agriculture and construction. When diesel spikes, freight costs rise, producer prices follow, and consumer prices surface with a lag. Analysts are flagging that pass-through as a fresh inflation risk exactly as the harvest and holiday shipping seasons arrive, when freight demand peaks. The surge has already added well over seven hundred dollars to annual household fuel costs since late February, and the pain extends well beyond the gas pump into the freight, manufacturing, agriculture, retail and fulfillment networks that depend on diesel-powered transportation.
- The disruption is threefold. First, the Strait of Hormuz, which normally carries about twenty million barrels a day — roughly a quarter of globally traded seaborne oil — is severely constrained. Iran has declared it closed, laid mines, and attacked vessels. Q2 flows collapsed to just 4.9 million barrels a day. Second, on the other side of the region, Houthi forces have seized the islands controlling Bab el-Mandeb — Mocha, Perim, Hanish, and Zuqar. That gives them control of Yemen's Red Sea coast, and they say navigation is safe except for Saudi vessels. Third, after drone attacks launched from Iraq hit its pumping stations, Saudi Arabia shut its east-west pipeline, the main bypass that carried Gulf crude to Yanbu on the Red Sea. That pipeline had a capacity of five to seven million barrels a day. With both straits constrained and the pipeline down, Gulf exporters have lost the alternatives that once cushioned the market.
- The exact figures carry some dispute. While the widely-cited numbers are six dollars and five cents for diesel and four dollars and twenty-nine for gasoline, other readings for the same day show slightly higher — six dollars and twenty cents for diesel. And while most estimates put Hormuz's share of seaborne oil at a quarter, some analysis suggests over a third.
- The surge has already added well over seven hundred dollars to annual household fuel costs.
- What is unresolved is how long the pressure holds. Prices move daily, the straits remain contested in a war with no end in sight, and each ceasefire and each renewed strike swings the numbers. Diesel rose in a sequence: five dollars and eighty-five on September 8th, past six dollars on the 11th, and the record on the 13th. The exact path forward is tied to the conflict itself. For now, the record at the pump is the visible face of an inflation risk that Washington cannot control at the chokepoint and cannot shelter the household from.
