When Hormuz transit failed, the region's two pipeline alternatives absorbed a fraction of normal volumes. The rest was shut in rather than rerouted, because there was no route for it — which is the measure of how much bypass capacity actually exists.

如何解讀等級
- 已證實 有來源記錄其已經發生。
- 合理可信的曝險 Vigil評估為很可能的機制；尚無其已經發生的紀錄。
- 未經證實的情境 因為值得觀察而列出。並非斷言。
一個步驟的等級永遠不能高於它所依賴的步驟：結果的確立程度不能高於其原因。這項規則在本網站建置時強制執行，而非以人工套用 — 違反它的鏈會導致建置失敗，而不會被發布。
- 觸發因素
自2026年2月起，經荷莫茲海峽的可靠商業通行喪失
- 受影響的資產、路線或地區已證實
沙烏地阿拉伯、伊朗、阿聯、科威特與巴林的原油與成品油出口，全都在一個唯一出口就是該海峽的封閉海域內裝載。受影響國家在2026年2月的戰前產量合計約21.7百萬桶/日。
有來源記錄其已經發生。
- 營運中斷已證實
通行變得不可靠，貨物無法穩定運送。歸因於關閉的減產形成一組有日期的序列：2026年3月約每日7.53百萬桶，4月預測為9.10百萬桶，5月11.3百萬桶，6月預測為11.34百萬桶，第三季預測緩和至10.11百萬桶。

The fixed alternatives could absorb only part of it. All bypass routes combined — the Saudi east-west system, the Emirati Fujairah line, the minor Iraqi line to Türkiye and Iran's barely used Jask route — have been assessed at roughly 3.5 to 5.5 million b/d against normal Hormuz volumes of about 20 million. The Saudi route is limited by terminal throughput rather than pipeline capacity, and the Emirati route was itself struck in March and again in May. In September 2026 the largest alternative was itself interrupted: the east–west pipeline was struck and shut on 10 September, and from mid-September Saudi crude went back through the strait it exists to avoid, on short legs under United States naval escort to transfer points off Sohar, until the line was reported restarted at a low rate on 22 September and Yanbu loading resumed between 25 and 28 September, on unnamed sources and with no operator statement. By Kpler's minimum confirmed count, September crude exports from the Gulf excluding Iran were back at the pre-war average of about 16.5 million b/d by a changed route — about 60 per cent across the strait, mostly on shuttle tankers, 23 per cent from the Gulf of Oman coast, mainly Fujairah, and 17 per cent through the Red Sea, against 83 per cent across the strait before the war.

- 更廣泛的經濟意義合理可信的曝險
Most of the constrained volume had no route at all, which is why the effect appeared as production shut in rather than as cargo rerouted. Bypass infrastructure in this region reduces exposure at the margin and changes who is exposed; it does not substitute for the strait, and describing it as an alternative to Hormuz overstates it by roughly a factor of four. The September recovery confirms the point rather than refuting it: volume came back because state companies rebuilt the route around the strait's risk — shuttles, transfers and escort as well as the bypasses — and when the pipeline was cut the substitute for the bypass was the strait itself. Volume and commercial access separated; no war-risk cover was found written on terms charterers take up in any review to 25 October.

仍然未知的事項
- The 3.5-5.5 million b/d combined figure is a specialist assessment by a named academic source, consistent with every primary component figure but not itself a published statistic.
- How much of the shut-in total reflects an inability to route cargo rather than demand loss or voluntary restraint is not established.
證據同樣支持的其他解讀
- Shut-ins may partly reflect producers declining to sell into a disrupted market rather than being unable to move cargo. The distinction matters for how quickly volumes return and is not resolved here.
