Summary
A fragile two-week ceasefire between the US and Iran was announced on April 8, brokered by Pakistan. Iran agreed to reopen the Strait of Hormuz conditionally. Oil prices crashed 12% on the news, then partially recovered as Iran accused the US of violating the deal within 24 hours. Negotiations set for Islamabad on April 10.
The Ceasefire Deal
On April 8, the US and Iran agreed to a two-week ceasefire in the 2026 Iran war, mediated by Pakistani PM Sharif. The terms:
- US and Israel halt attacks on Iran for two weeks
- Iran agrees to “complete, immediate, and safe opening” of the Strait of Hormuz
- Negotiations to continue in Islamabad starting April 10
- US delegation led by VP JD Vance, Special Envoy Steve Witkoff, and Jared Kushner
Trump had issued an ultimatum on April 7, threatening strikes on Iranian infrastructure (“power plant day, and bridge day”) if the Strait was not opened. The ceasefire came after he backed down from that deadline.

Oil Price Shock
The ceasefire triggered the biggest single-day oil price drop since 2020:
- Brent crude fell 12%, from ~$109 to $94.75/barrel on April 7-8
- By April 9, Brent recovered to $97.42 (+2.8%) as ceasefire doubts grew
- WTI crude followed a similar pattern
- The market priced in partial Hormuz reopening but hedged against collapse

Iran Threatens Bab al-Mandeb
In a separate escalation, Iran threatened to close the Bab al-Mandeb strait (connecting the Red Sea to the Gulf of Aden), which would compound the Hormuz disruption by blocking an alternative shipping route.

Our Thinking
This ceasefire is a pressure release valve, not a resolution. The speed at which violations were alleged (under 24 hours) signals how fragile the deal is. The oil market’s reaction tells the story: a 12% crash followed by an immediate 3% recovery. The market does not believe this holds.
Key dynamics to watch:
- The Islamabad talks on April 10 are the real test. If Vance/Witkoff can extract a durable Hormuz commitment, oil could settle in the $85-95 range. If talks collapse, we’re back above $120 fast.
- Iran’s Bab al-Mandeb threat is a new escalation vector. Closing both straits would be catastrophic for global shipping.
- The ceasefire does not address the underlying conflict. Israel’s campaign in Lebanon continues. Iran’s nuclear program is unresolved.
Watch
- Islamabad negotiations April 10
- Hormuz shipping traffic data over the next 48-72 hours
- Iran’s actual compliance on strait reopening
- Israeli military activity in Lebanon during ceasefire window
- Brent crude trajectory: below $90 = market believes; above $110 = market calls bluff
