随着美伊两国再度爆发军事冲突，燃油价格正再度上涨。
根据美国汽车协会（AAA）的数据，美国全国汽油均价上周五升至每加仑3.88美元，较一周前的3.84美元有所上升。近几周来，在美国和伊朗于上月签署临时停火协议后，加油站油价曾于7月5日跌至每加仑3.80美元的低点，而5月时油价曾超过4.50美元。
今年2月底伊朗战争爆发前，普通汽油均价为每加仑2.98美元。这家汽车行业组织在一份报告中表示：“随着美伊之间停火协议的未来走向仍不明朗，汽油价格再度上涨。”
中东地区最新一轮暴力冲突再度引发担忧，人们担心长期冲突可能会扰乱霍尔木兹海峡的贸易往来。这条波斯湾水道承担了全球约20%的能源运输量。特朗普总统上周五重申了他的立场，称美伊之间的停火协议在生效不到三周后就“已失效”，同时他也表示美国将继续进行谈判。
据标普全球市场情报部门（S&P Global MINT）和标普全球海上大宗商品部门的数据，周四通过该海峡的船舶数量降至34艘，为6月28日以来的单日最低水平。6月28日，美国对伊朗伊斯兰共和国发动空袭后，伊朗在该地区发动了无人机袭击。
这家金融研究公司在谈到7月9日通过该海峡的船舶时表示：“与伊朗有关联且受制裁的船舶数量仍居高不下，约占总过境船舶的三分之一。”
根据美国能源信息署的数据，原油成本占每加仑汽油售价的51%，是影响燃油价格的最大因素。将原油提炼为汽油、喷气燃料、取暖油和其他能源产品的成本约占汽油价格的20%；其他影响因素包括营销和分销费用，以及地方和联邦税收。
其他地缘政治事件也在限制全球原油和天然气供应。追踪美国汽油价格的GasBuddy石油专家帕特里克·德哈恩表示，乌克兰对俄罗斯炼油厂及其他设施的袭击造成了损失。
他在一份报告中称：“俄罗斯境内每一座被关闭的炼油厂，都会让包括汽油和柴油在内的成品油退出全球市场，即便原油本身仍在正常运输。”
德哈恩补充道：“莫斯科的回应让本已紧张的全球市场变得更加收紧。俄罗斯目前已经全面禁止柴油出口，叠加此前对汽油和喷气燃料出口的现有限制，试图将燃油留在国内。”
德哈恩还指出，夏季驾车出行旺季的季节性回升会推高燃油需求，进而推高汽油价格。与此同时，环保规定要求炼油厂生产夏季混合汽油以减少高温下的蒸发——他表示，这种转型每加仑汽油的成本会增加10至25美分。

Gas prices climbing again as U.S.-Iran tensions flare

Fuel prices are headed back up amid renewed military clashes between the U.S. and Iran.
The national price of gasoline rose on Friday to $3.88 a gallon, up from $3.84 a week ago, according to AAA. In recent weeks, prices at the pump fell to as low as $3.80 on July 5, down from more than $4.50 in May, after Washington, D.C., and Tehran signed a temporary ceasefire last month.
Regular gas averaged $2.98 a gallon just before the Iran war started in late February. “Gas prices are going up again, as the future of the ceasefire between the U.S. and Iran remains uncertain,” the auto group said in a report.
The latest spasm of violence in the Middle East is reviving concerns that a prolonged conflict could disrupt trade through the Strait of Hormuz, the Persian Gulf waterway that handles roughly 20% of global energy flows. President Trump reiterated his stance on Friday that the ceasefire with Iran was “over” after less than three weeks, while noting that the U.S. would continue negotiating.
The number of ships traversing the strait on Thursday fell to 34, the lowest daily level since June 28, when Iran launched drone attacks in the region following U.S. airstrikes on the Islamic Republic, according to S&P Global MINT and S&P Global Commodities at Sea.
“Iran-linked and sanctioned traffic remained elevated, accounting for roughly one-third of total crossings,” the financial research firm said of the ships navigating the strait on July 9.
The price of oil accounts for 51% of the cost of a gallon of gas, making it the biggest factor affecting fuel prices, according to the Energy Information Administration. The cost of refining crude into gas, jet fuel, heating oil and other energy products accounts for roughly 20% of gas prices; other factors include marketing and distribution expenses, as well as local and federal taxes.
Other geopolitical events are also constraining the world’s crude and gas supplies. Attacks by Ukraine on Russian oil refineries and other facilities are taking a toll, according to Patrick De Haan, a petroleum expert at GasBuddy, which tracks U.S. gas prices.
“Every refinery knocked offline in Russia removes refined products like gasoline and diesel from the global market, even if crude oil itself keeps flowing,” he said in a report.
“Moscow’s response made a tight global market even tighter,” De Haan added. “Russia has now banned diesel exports outright, layered on top of existing restrictions on gasoline and jet fuel exports, in an attempt to keep fuel inside the country.”
De Haan also noted that the seasonal pickup in driving, when fuel demand typically jumps during the summer, pushes up gas prices. Meanwhile, environmental rules require refineries to produce summer-blend gas to reduce heat-related evaporation — a shift that can cost between 10 and 25 cents per gallon, he said.
