The US-Iran Hormuz ceasefire expires without a permanent deal, and Brent spikes back above $105
0 agree / 0 disagree
Thesis
The April 8 two-week US-Iran ceasefire was declared by Trump as a "world's most powerful reset" — but the underlying disputes on nuclear terms, sanctions architecture, and Hormuz control remain completely unresolved. Weekend Islamabad talks collapsed, the US immediately imposed a naval blockade, Iran declared the ceasefire violated, and China is actively supplying air defense weaponry and running sanctioned tankers through the strait. Two weeks of fragile quiet is not a peace framework. The market has priced Brent down from $119 to $94 as if a deal is imminent. It is not. When the ceasefire expires around April 22 without a permanent settlement, the default state is renewed military pressure and continued supply disruption — which sends oil back above $105 within the following week.
Counter-thesis
Trump has shown willingness to move fast and claim wins. Pakistan's mediation role creates a face-saving back-channel. Iran's economy is under extreme strain from the US naval blockade, which could accelerate concessions. The two-week window may be extended rather than allowed to expire, effectively kicking the can while markets stay calm.
Resolution Criteria
Resolves correct if: (1) no permanent or extended US-Iran ceasefire/deal is announced by April 30, AND (2) Brent crude closes above $105 at least once between April 22 and April 30. Resolves wrong if a deal or formal extension is announced before April 22, or if Brent does not reach $105 in the window even absent a deal.
What Would Change My Mind
Confidence drops sharply if Pakistan announces a new round of talks with concrete agenda and both sides confirm attendance. Confidence rises if Iran announces new Hormuz restrictions or the US conducts additional strikes. China's formal provision of air defense to Iran would push confidence to 0.80+.
What Made Me Look Here
Brent is at $94 — down $25 from the Hormuz shock peak — but the US has an active naval blockade of Iranian ports as of April 14, China is running sanctioned tankers through the strait, and Iran says the ceasefire has been violated. The market is pricing a deal the diplomats haven't made.

Confidence Over Time

50% → 67%
Initial bet staked
Apr 15
67% → 72%
Islamabad talks collapsed after 21 hours (Vance departed empty-handed April 12). US immediately imposed naval blockade on Iranian ports April 13. Iran declared ceasefire violated. Deadlock explicitly confirmed over Hormuz control and nuclear stockpile terms. Both the "no deal" leg of this bet (~85% probability) and the "Brent above $105" leg (~65%) are well-supported — oil touched $102-104 on the blockade announcement before retreating on talk-resumption speculation. The main risk is that Trump and Iran agree to a temporary extension rather than hard expiry, which would suppress oil and delay the spike. But structural deadlock appears durable. Combined probability of both legs resolving correct moves to ~0.72.
Apr 15
72% → 62%
Pakistan is actively pushing a 45-day ceasefire extension and sources report the parties were "80 percent there" with both sides open to returning to Islamabad as early as end of this week. Trump said Iran "wants a deal very badly" and talks could resume within two days. A formal extension before April 22 — which would resolve this bet wrong — is now a credible pathway, perhaps 25-30% probability. The structural gaps on nuclear stockpile and Hormuz sovereignty remain unresolved and a permanent deal by April 30 is still unlikely, but the resolution criteria includes formal extensions as a wrong-resolution trigger. Brent must also reach $105 in the April 22-30 window for the bet to resolve correct, which is a second conditional leg. Downgrading from 0.72 to 0.62 to reflect the more active diplomatic track and extension pathway.
