Summary
In the early hours of August 1, Middle East tensions escalated again, international oil prices surged sharply, WTI crude oil futures closed up 3.84%, Brent crude oil rose over 4% at one point. US officials revealed that Trump has ordered a new round of military strikes on Iran's energy infrastructure, aiming to force Iran to surrender, with the action possibly starting this weekend and lasting several days. Overnight, the US stock market showed a V-shaped reversal, with the Nasdaq up 1%, the S&P 500 up 0.7%, and the Dow Jones up 0.53%. The seven tech giants collectively rose 3.2%, with Amazon up over 15% in a single day, Google up over 6%, Microsoft up over 3%, Nvidia up nearly 3%, regaining the title of world's most valuable company; Apple fell over 7%, SpaceX down over 3%. Chip stocks showed mixed performance, with the memory chip sector broadly declining; SanDisk, Micron Technology fell over 5%, SK Hynix ADR down over 3%, Kioxia ADR down over 10%. Analysis indicates that the recent turbulence in US AI hardware stocks stems mainly from leverage unwinding rather than deteriorating fundamentals; over the past three trading days, the largest unilateral leverage unwinding since November 2022 occurred, as funds are clearing leverage positions built in April-May, amplifying volatility. The article cites multiple sources including CCTV News, a Pentagon spokesperson, maritime traffic website, Keppler Company, and Goldman Sachs data.

国际油价大幅拉升
今日凌晨，在国际能源市场收盘后，WTI原油期货价格在电子交易盘大幅拉升，收涨3.84%。
据央视新闻客户端消息，当地时间7月31日，美国官员表示，美国总统特朗普已下令对伊朗发动新一轮袭击，目的是迫使德黑兰方面投降。相关行动最早可能于本周末开始，并持续数天。
特朗普7月31日早些时候对外表示，他计划恢复对伊朗的大规模军事打击，以迫使伊朗政府重返谈判桌。
特朗普还称，如果美国对伊朗施加足够强大的军事压力，伊朗强硬派政权最终将逐渐“撑不下去”。
此前，美国方面有多名消息人士称，以色列方面已获知美国欲对伊朗能源基础设施发动一轮大规模轰炸的相关计划，并正与美国协调。有关方面曾讨论争取在8月3日金融市场开盘前结束行动，以减少轰炸对美国和全球经济的影响，但尚未确定具体结束时间。
两名消息人士称，发电厂和炼油厂可能成为打击目标。美国高层还讨论了切断德黑兰电力供应的可能性。
据称，这项军事打击计划在7月31日特朗普于戴维营举行的内阁会议上被讨论。特朗普当天表示：“我们会非常猛烈地打击他们。”
五角大楼首席发言人肖恩·帕内尔表示，在总统作出最终决定前，五角大楼不会评论具体目标，并称国防部已做好准备，可随时执行总统指令。
美国方面还有分析称，如果美以实施联合行动，这将标志着以色列恢复此前在美国斡旋停火期间暂停的作战行动。
另外，伊朗“波斯湾海峡管理局”于当地时间7月31日发布声明称，由于美军在相关海域持续采取侵略性行动，目前霍尔木兹海峡已无法正常通行。对此，美军中央司令部称，“这是不实的消息，霍尔木兹海峡对于商船通行依然保持开放，伊朗并不控制该海峡”。
国际航运信息平台“海上交通网站”7月31日公布的数据显示，霍尔木兹海峡30日的船舶通行数量从前一天的22艘降至5艘，降幅达77%。
该平台数据显示，这5艘船全部经伊朗一侧航道通过霍尔木兹海峡。
国际市场服务机构克普勒公司30日在社交媒体上发文说，持续存在的海上安全风险、战事保险成本等目前似乎已成为制约海湾地区原油出口的主要障碍。

隔夜美股市场方面，三大指数上演V字反转走势，盘初一度集体跳水，随后集体反攻，截至收盘，标普500指数涨0.7%，纳指涨1%，道指涨0.53%。
大型科技股多数上涨，“科技七巨头”整体涨幅达3.2%，亚马逊大涨超15%，创2012年以来单日最大涨幅；谷歌大涨超6%，微软涨超3%，英伟达涨近3%，总市值4.86万亿美元，重夺全球“股王”的位置；苹果跌超7%，创2025年4月以来最大跌幅；SpaceX跌超3%，7月份累跌超36%。
芯片股整体表现平淡，费城半导体指数微涨0.07%，但仍较6月22日历史高点下跌逾20%。
存储、光通信板块涨跌不一，铠侠ADR大跌超10%，闪迪、美光科技跌超5%，SK海力士ADR跌逾3%；Coherent涨超5%，西部数据、康宁、迈威尔科技涨超2%。其中，铠侠ADR7月份累跌53%，闪迪7月份累跌超46%，美光科技7月份累跌超28%。
有分析人士指出，近期美股AI硬件股的剧震为“仓位事件而非AI基本面恶化的开端”，该领域的高杠杆水平如同放大器，加剧了价格波动，动量因子7月暴跌25%，创2009年5月以来最差单月表现。
据高盛Prime经纪数据，过去三个交易日出现自2022年11月以来最大规模的单边去杠杆，基金正在大规模出清4月至5月间建立的杠杆头寸，尤其集中于内存芯片及半导体持仓。
