US-Iran Tensions Escalate as Ceasefire Collapse Sparks Global Market Volatility
US Strikes Target Iranian Facilities After Alleged Merchant Ship Attacks

On July 8, the US Central Command announced a series of strikes on Iranian military facilities, marking the first major escalation since the 16-day ceasefire agreement between Washington and Tehran. The operation, described as “four to five times larger” than a previous strike 10 days prior, targeted key infrastructure in southern Iran, including the Sirik port and commercial docks, according to US officials. Explosions were reported in Gheshm Island and Abbas Port, with local authorities confirming damage to critical infrastructure.
According to Reuters, the US cited Iranian involvement in attacks on three merchant vessels in the Strait of Hormuz as justification. The UK Maritime Trade Operations confirmed three incidents within 24 hours, including an oil tanker struck by an “unknown projectile” near Oman. The Rekaya, operated by a Qatari state-owned shipping company, was among the vessels targeted. The UN International Maritime Organization pointed out that this was the day with the highest number of attack incidents in the Strait of Hormuz since the end of April this year.
Economic Pressure Mounts as US Revokes Oil Export Waiver
In tandem with the military strikes, the US Treasury Department terminated a 60-day waiver allowing Iran to sell oil, effectively reinstating sanctions. The move, announced by the Office of Foreign Assets Control, aims to cut off Iran’s important revenue source. Iranian Foreign Ministry Deputy Minister Garibbadi condemned the decision, calling it a violation of the June 18 memorandum of understanding (MoU) that had temporarily eased tensions.
The abrupt cancellation of the oil waiver has already impacted global markets. Brent crude surged past $75 per barrel, while WTI futures rose over 5% in early trading.
Iran Denies Attacks, Warns of Retaliation
Iranian officials have consistently denied involvement in the ship attacks, instead accusing the US of fabricating evidence to justify its strikes. The Iranian Persian Gulf Strait Authority reiterated its demand that vessels adhere to designated routes, claiming that any vessels deviating from designated routes would not receive safety guarantees.
Despite the lack of confirmed civilian casualties, Iran’s Foreign Ministry warned of “all necessary measures” to protect national sovereignty. Deputy Foreign Minister Garibbadi also accused the US of hypocrisy, citing recent Israeli military actions in Lebanon as evidence of Washington’s “unreliable” conduct.
Regional and Global Implications of the Ceasefire’s Collapse
The rapid breakdown of the MoU highlights the fragility of diplomatic efforts in the Middle East. The agreement, hailed as a potential “turning point” for regional stability, lasted just 16 days before collapsing under the weight of conflicting narratives.
The incident also raises questions about the role of third-party actors. The UK’s Maritime Trade Operations reported that the attacked vessels were using a “southern route” along Oman’s coast, a path opened by the US military.
