美國封鎖伊朗港口，點樣拖動船運風險、油價同談判？
4月伊斯蘭堡談判破裂後，美軍被報道開始封鎖伊朗港口，令海灣航運風險、油價波動同談判條件同步升溫 [23][24]。 油價不是單向上升：曾因供應風險升穿每桶100美元，又因重啟對話希望跌穿100美元，之後隨霍爾木茲限制持續再上升 [23][27][28]。

美國對伊朗港口嘅海上封鎖，已經唔只係軍事施壓，而係牽一髮動全身：船運公司要重新計風險，油市要重新計供應溢價，外交談判亦要先處理霍爾木茲海峽通行權。據路透社內容報道，美軍在巴基斯坦首都伊斯蘭堡談判破裂後開始封鎖伊朗港口，激怒德黑蘭，並令呢條關鍵水道前景更不明朗；不過，市場一度憧憬雙方可重開對話，令基準油價短暫跌穿每桶100美元 [23][
24]。
最值得留意嘅，唔係簡單一句「油價必升」或者「所有船都過唔到」，而係三個互相牽動嘅變化：航運風險外溢、油市風險溢價忽高忽低，以及海上通行權變成談判條件。
航運：未必係全面封海，但風險已經外溢
公開報道主要將美方行動描述為封鎖伊朗港口；受影響嘅，是經霍爾木茲海峽來往伊朗嘅船隻 [28]。呢個分別好關鍵：報道中嘅美方封鎖，唔等於已宣布全球所有海灣商業航運一律停航。
但德黑蘭嘅回應，將本來集中於伊朗相關貨物嘅風險推到更闊。伊朗聯合軍事指揮部發言人警告，如果波斯灣同阿曼海嘅伊朗港口受威脅，該水域「沒有任何港口」會安全；又稱「與敵方有聯繫」船隻無權通過霍爾木茲海峽，其他船隻則可按伊朗軍方規例通行 [19]。
對船東、租船人同保險商嚟講，最麻煩正正係呢種模糊地帶。即使一艘船唔係運載伊朗貨物，營運方都要評估船東背景、船旗、融資安排、目的港同租約關係，會唔會被任何一方視為敵對或敏感。其後路透社內容報道亦提到，霍爾木茲相關貿易限制仍然持續，並有伊朗扣押船隻及美方攔截伊朗油輪嘅報道 [27]。
所以，較穩陣嘅講法係：封鎖令海灣航運嘅不確定性、延誤同航線風險判斷增加。現有資料未足以可靠估算總損失貨量、保險費升幅或滯期費成本。
