Trump Declares US-Iran Ceasefire Over as Brent Crude Surges 6%

The June 17 MoU is dead, the sanctions waiver is gone, and Hormuz is back in play, oil markets are already pricing the damage.

Key takeaways

• Trump declared the US-Iran Memorandum of Understanding "over" at the NATO summit in Ankara on July 8, 2026, after Iran attacked three commercial vessels in the Strait of Hormuz and CENTCOM retaliated with strikes on more than 80 Iranian targets overnight.
• The US Treasury revoked General License X on July 7, snapping back the sanctions waiver that had allowed Iran to sell oil under the June 17 MoU, effective immediately for new sales.
• Brent crude surged roughly 6% to around $78-79 per barrel, per reporting from CBS News and Time; with the US Navy-led Joint Maritime Information Center (JMIC) raising the Hormuz risk rating to "Severe" from "Substantial," per Al Jazeera, freight rates, insurance costs, and energy prices face sustained pressure.

President Trump, speaking at a bilateral press conference alongside NATO Secretary General Mark Rutte at the Beştepe Presidential Compound in Ankara on July 8, 2026, called the US-Iran ceasefire finished. "I think it's over. I don't want to deal with them anymore. They're scum," Trump told reporters, per NPR and Time. "They're sick people, they're led by sick people, and they're vicious, violent people. And if they had a nuclear weapon, they'd use it," he continued, per CBS News and Time.

The remarks landed after a full cycle of escalation: Iran targeted three commercial vessels in or near the Strait of Hormuz on July 7, CENTCOM struck more than 80 Iranian targets overnight in retaliation, and Iran's IRGC then launched missile and drone strikes against US military facilities in Bahrain and Kuwait. Both countries intercepted the incoming fire, with no material damage reported, per Time and CBS News.

What Broke the Deal

The June 17 MoU, signed at the Palace of Versailles during the G7, had established a 60-day ceasefire with a mid-August expiration, per Time and Al Jazeera. Its core economic incentive was the sanctions waiver allowing Iran to sell oil. The US Treasury revoked that waiver (General License X) on July 7, effective immediately for new sales, with a grace period covering cargoes already at sea before that date. A US official quoted by CBS News framed the logic plainly: "The MOU in effect with Iran is entirely performance-based. Iran will only reap benefits if they exhibit good behavior."

Iran's attack on three tankers, the Marshall Islands-flagged M/T Al Rekayyat, the Saudi-flagged M/T Wedyan, and the Liberian-flagged M/T Cyprus Prosperity, per Al Jazeera citing CENTCOM and CENTCOM's official press release, was the performance failure that collapsed that structure. CENTCOM confirmed the strikes destroyed Iranian air defense systems, coastal radar, anti-ship missile capabilities, and more than 60 IRGC small boats.

Trump stopped short of ordering a full resumption of the war. "I'll let our wonderful negotiators keep talking if they want, but I don't see it," he said, per Time.

The Inflation Transmission Nobody Is Pricing

Before this conflict, roughly 20-25% of the world's seaborne oil and approximately 20% of its LNG passed through Hormuz, per Al Jazeera. Brent had already traded above $100 per barrel earlier in the war, per CBS News. At around $78-79 on a single morning's remarks, the market is not yet pricing a full closure, but it is pricing the removal of the normalization assumption.

That removal has a direct path into CPI. Higher oil flows into transport, manufacturing, and food costs. The Federal Reserve is already navigating a fiscal trap: the US is carrying more than $36 trillion in debt, which means tightening into elevated energy costs produces punishing debt service. Loosening with oil above $80 reaccelerates inflation.

Sustained Hormuz disruption removes that optionality. The Fed's next move becomes constrained by a chokepoint it cannot bomb its way out of. This is a structural energy shock, not a cyclical one.

The dollar-weaponization dimension compounds it. Every time the US revokes a sanctions waiver mid-deal, every non-Western sovereign watching takes another step toward dollar alternatives. Iran cannot use SWIFT. It will settle oil in something else.

The yuan cannot fill that gap structurally (Beijing's capital controls make it impossible at scale). But the pressure accelerates de-dollarization regardless, and it does so in the one asset class where the petrodollar has historically been hardest to route around.

Bitcoin's supply schedule is indifferent to who is firing missiles or printing Treasuries to pay for the response. The macro condition being assembled here, negative real yields, an inflation shock the Fed cannot cleanly address, and accelerating dollar-alternative pressure, is the same condition that has historically preceded Bitcoin's hardest rallies. The IRGC's warning of "harsher" retaliation "in the coming days," per Al Jazeera, suggests this condition has more room to develop.

The falsifiable version of that thesis: if Brent retreats below $72 within 48-72 hours on credible back-channel reporting that negotiations have quietly resumed and Iran re-commits to free Hormuz passage, and 10-year Treasury yields hold or drop, then this is another risk flare with no lasting inflation pass-through. That would be the signal the thesis is wrong for now.

What to Watch

The IRGC's explicit threat of further retaliation sets the next trigger. Watch Brent's behavior above or below $80, any credible back-channel reporting on renewed talks, and the state of Hormuz vessel flows as freight and insurance markets reprice. The NY Fed's June 2026 Survey of Consumer Expectations, released July 7, put 1-year inflation expectations at 3.7%, the highest since September 2023, before this session opened.

Update, July 8, 2026

Trump approved and ordered the strike package personally from Ankara, convening Secretary of State Rubio, Defense Secretary Hegseth, Treasury Secretary Bessent, and Joint Chiefs Chairman Gen. Dan Caine before the order went out, per Fox News. The targeting list went beyond air defense and IRGC small boats: US strikes also hit coastal surveillance systems, surface-to-air missiles, anti-ship cruise missiles, and drone launch sites , and port facilities were included as active targets . Explosions were confirmed at Qeshm Island and the port of Sirik on Iran's southern coast, both key nodes for Iranian control over the strait, but the most significant strike may have been on Kharg Island. Kharg Island, a five-mile stretch off the Iranian coast, is a vital hub for Tehran's oil exports that typically handles roughly 90% of the country's crude oil shipments , and Iranian state media reported several blasts there.

On the sanctions mechanics, Treasury's revocation was more surgical than a simple snap-back. Treasury issued General License X1 revoking prior authorities as of July 7, barring new purchases, loading, or shipments of Iranian oil, while allowing only transactions necessary to complete deals already authorized under General License X through July 17, with any payments to blocked persons required to go into interest-bearing blocked accounts in the US rather than remaining available to Iran. Iran's Foreign Ministry framed that as a breach of Article 10 of the MoU, which had explicitly guaranteed oil export waivers, and said it would take any measure it deemed necessary to safeguard its interests and national security.

Iran's posture heading into July 8 is unambiguous escalation. An advisor to new Supreme Leader Mojtaba Khamenei, Mohsen Rezaei, stated that "Trump intends to attack again, and we are fully prepared." Iran's Parliament Speaker Ghalibaf posted that "The era of bullying and extortion is over. It leads nowhere. We don't fold." CENTCOM, for its part, closed its strike statement with a direct warning: "CENTCOM forces remain postured and prepared to hold Iran accountable when the agreement is not adhered to or obeyed." With Kharg Island, Iran's primary crude export terminal, now in the strike zone, the oil market is not pricing a corridor disruption anymore. It is pricing a supply destruction event.
