US-Iran Ceasefire on the Brink of Collapse, Washington Revokes Oil Export License After Three Tankers Attacked in Strait of Hormuz

Tensions between the United States and Iran have escalated again in the past forty-eight hours. The US Treasury Department, through the Office of Foreign Assets Control (OFAC), revoked the license that had allowed the sale of Iranian oil and petrochemical products to global markets, effective immediately as of Tuesday, July 7. This move came just hours after three tankers were attacked in and around the Strait of Hormuz, the world's most vital oil shipping lane.

Making the situation even more critical, President Trump stated today on the sidelines of the NATO summit that he believes the memorandum of understanding between the US and Iran has already ended, a statement that signals the fragility of the diplomatic foundation built less than a month ago.

Frequently Overlooked Context: A War That Has Not Truly Ended

It is important to understand that today's tensions do not stand alone. The US and Iran are actually still in a state of open war that began on February 28. The memorandum of understanding that is now threatened with collapse was signed on June 17 in Islamabad, not in Switzerland as previously often mentioned, and is known as the Islamabad MOU. This agreement opened a sixty-day negotiation window, in which Iran agreed to halt attacks and reopen the Strait of Hormuz to commercial vessel traffic, while the US provided limited sanctions relief including the oil sales license.

The situation becomes more complicated as it coincides with the death of Iran's Supreme Leader, Ayatollah Ali Khamenei, whose body is currently lying in state in Tehran before being buried in Mashhad. President Trump had given a one-week grace period for Iran to hold mourning ceremonies, but that period was instead used by Iran to continue attacks on ships in Hormuz, triggering this latest escalation.

Details of the Revoked License

The license revoked today, known as General License X, was previously issued on June 21 and was supposed to remain valid until August 21. The license permitted the production, shipping, sale, and payment in US dollars for Iranian oil, Teheran's main source of revenue. This policy had drawn sharp criticism as it was seen as a major concession amid unresolved nuclear and regional tensions, although the US repeatedly emphasized that the agreement was entirely conditional on Iran's behavior.

With this revocation, all ongoing Iranian oil transactions must be completed no later than July 17, cut short from the original deadline that still had more than a month remaining.

Chronology of Attacks That Triggered Escalation

Between Monday night and Tuesday, at least three commercial vessels were attacked while crossing the Strait of Hormuz. UK maritime authorities reported that a Saudi Arabian oil tanker named Wedyan was one of the targets, while a Qatari liquefied natural gas tanker named Al Rekayyat was reported to have been at risk of exploding due to a fire in its engine room. A third ship was reported to have caught fire off the coast of Oman. Saudi Arabia strongly condemned the incident as an attack on international navigation security and global energy supply.

The root of the problem actually stems from a dispute over shipping lanes. Iran insists that ships must pass through the northern route it controls and pay certain fees, while the majority of ships choose the southern route near the Omani coast guarded by the US Navy, given that the traditional central Hormuz route has been mined by Iran. International maritime authorities raised the threat status for vessels crossing this strait to the severe category.

US Military Response

Just hours after the license revocation, US Central Command confirmed it had launched retaliatory strikes against more than eighty targets inside Iranian territory, including air defense systems, command and control networks, coastal radars, anti-ship missile capabilities, and more than sixty small boats belonging to the Islamic Revolutionary Guard Corps. US military forces also reportedly shot down several additional drones launched by Iran.

From the Iranian side, Deputy Foreign Minister Kazem Gharibabadi accused the US of repeatedly violating the memorandum of understanding, citing the continued presence of Israeli military forces in Lebanon as one trigger for Teheran's anger. He warned that Iran would take firm steps to protect its national interests and security.

Shockwaves in Financial Markets

Oil prices surged sharply in response to this series of events. Brent crude closed up about five and a half percent to above seventy-five US dollars per barrel, even touching seventy-five point eighty-eight dollars in post-settlement trading. US WTI crude also strengthened more than five percent to around seventy-two US dollars per barrel. US government bond yields rose accordingly, with twenty and thirty-year tenors breaking through the five percent level, while ten-year yields reached their highest level since early June.

In stock markets, the Dow Jones index closed down one hundred thirty point seventy-six points or zero point twenty-five percent to 52,925, while the S&P 500 fell zero point forty-five percent and the Nasdaq Composite plunged one point sixteen percent, pressured by massive sell-offs in semiconductor stocks. Entering pre-market trading today, July 8, futures for all three major Wall Street indices weakened again, indicating continued selling pressure following President Trump's latest statements at the NATO summit.

Fate of Iranian Oil Exports

Before this license was revoked, Iran had managed to take advantage of the window to load and sell about sixty million barrels of oil. Although sanctions are now back in full force, Teheran will likely still be able to channel its oil to buyers like China through discount pricing schemes and non-dollar payment settlements, a pattern that has long been Iran's survival strategy under international sanctions pressure, albeit with much higher risks and logistics costs.

Outlook Ahead

Negotiations toward a final agreement covering the nuclear program issue and permanent security of the Strait of Hormuz were actually still ongoing, but several reports indicate that Iran has delayed comprehensive discussions until at least July 18, and is only willing to continue talks at the technical level for now. Coupled with President Trump's statement that the memorandum of understanding has ended, the direction of future negotiations has become increasingly uncertain.

The Strait of Hormuz itself handles about twenty percent of world oil trade, making any disruption at this point potentially destabilizing for global energy stability and inflation. Against the backdrop of a war that has been ongoing since late February, the death of Iran's supreme leader, and the continuing series of attacks and retaliations, the situation in the Middle East heading into the end of 2026 appears increasingly prone to erupt into a broader conflict, far beyond just an oil trade dispute.
