WASHINGTON/TEHRAN, July 18 — The United States launched a seventh consecutive night of strikes against Iranian military targets on Friday as Tehran fired back at American facilities in Kuwait, pushing crude oil prices to their highest level in over a month and sending global equity markets sharply lower.
The escalation marks a significant intensification of the week-old confrontation. Iran’s Islamic Revolutionary Guard Corps (IRGC) claimed responsibility for an attack that it said engulfed a U.S. military base in Kuwait in flames, targeting radar installations, weapons stockpiles, and HIMARS rocket systems. Separately, Iranian state media reported explosions across multiple provinces, including Bushehr, Hormozgan, and Yazd.
Markets React Sharply
Financial markets registered the growing geopolitical risk with unusual intensity. West Texas Intermediate (WTI) crude settled at $82.49 per barrel, up 4.48% on the day and a staggering 14.35% for the week — the largest weekly gain since early 2023. Brent crude followed a similar trajectory, climbing 4.59% to $88.10.
Equity markets moved in the opposite direction. The Nasdaq Composite fell 1.4%, extending its weekly decline to 2.9%. The Philadelphia Semiconductor Index, once the market’s darling, has now corrected more than 20% from its June peak, officially entering bear market territory as investors rotated out of AI and technology names into energy, defense, and traditional commodities.
Gold held near the psychologically important $4,000-per-ounce level, trading at $4,023, though it posted a 2.56% decline for the week as some investors liquidated positions to cover margins elsewhere.
Regional Ripple Effects
The conflict’s geographic footprint continued to expand. Jordanian air defenses intercepted and shot down three Iranian missiles that entered its airspace, according to an official statement from Amman. Meanwhile, reports emerged that Washington is dispatching dozens of additional aerial refueling tankers to Israel at a rate of five to eight aircraft per day, signaling potential preparation for a broader Israeli role in the operations.
Mohsen Rezaei, military adviser to Iran’s Supreme Leader Ayatollah Ali Khamenei, declared that the US-Iran memorandum of understanding had become “a dead letter,” accusing Washington of systematically violating its terms. The statement suggested Tehran sees little diplomatic off-ramp in the immediate future.
What Analysts Are Watching
Michael James, managing director of trading at Rosenblatt Securities, described current market conditions as “extremely driven by sentiment and momentum rather than fundamentals.” He noted that Friday’s session did nothing to restore investor confidence ahead of Monday’s open.
Three questions now dominate geopolitical calculations: whether Israel will enter the conflict openly, whether Iran moves to close the Strait of Hormuz through which roughly 20% of global oil shipments pass, and how China and Russia — both with significant interests in the region — will respond to further escalation near their strategic peripheries.
