Brent crude fell about 4 per cent to $89.25 on 12 June, below $90 for the first time in the conflict window, as traders priced the ceasefire as more likely than not.

Key takeaway

Oil fell on ceasefire odds, not new barrels, so a missed signing would snap it straight back.

Brent Crude fell about 4 per cent to $89.25 on 12 June, slipping below $90 for the first time in the conflict window "after Trump suspended planned attacks" 1. The drop reverses the prior session, when Brent had reached $96.34 on the US-Iran exchange repricing Hormuz risk and then settled at $94.71 on CENTCOM (US Central Command)'s strikes-complete call . The $5.46 fall completes a round-trip on the de-escalation signal.

Iran's exports have tightened to between 209,000 and 260,000 barrels a day, down roughly 86 per cent from the 1.84 million before the war, with the physical supply picture barely changed this week. That collapse is old news to the market. The move is sentiment, not supply: the price tracks no new barrels, it tracks the odds of a ceasefire.

The market read Trump's stand-down as the real turn and Esmail Baghaei's denial as noise, putting the futures desk on the opposite side of Iran's own foreign ministry. One of them is wrong, and a weekend signing or a missed one will settle which by the close.

Deep Analysis

In plain English

Oil prices dropped sharply on Thursday because investors around the world bet that the fighting between the US and Iran was winding down. When conflicts in oil-producing regions calm down, oil prices usually fall because traders stop charging a "risk premium", the extra money built into the price in case the situation gets worse. The catch is that very little oil has actually started flowing again through the Strait of Hormuz. Iran's oil exports have been cut to almost nothing by the blockade, and that had not changed this week. The price fell because of hope, not because of new supply. If the deal Trump announced is not signed by the end of the weekend, expect oil prices to bounce back up just as fast as they fell.

Deep Analysis
Root Causes

Oil markets price Hormuz risk via a conflict premium that has no direct supply-chain transmission mechanism: Brent can fall 4 per cent on a stand-down even when zero additional barrels clear the strait, because the premium reflects a probability-weighted expectation of future supply, not current flows.

Kpler and Vortexa data confirm Iran's exports at 209,000-260,000 barrels per day are unchanged from the prior week . Kpler and Vortexa data confirm Iran's exports at 209,000-260,000 barrels per day are unchanged from the prior week , so the $5.46 fall prices ceasefire probability, not new barrels.

Lloyd's of London has not repriced Hormuz war-risk cover because its trigger requires a UN Security Council resolution or government certification, not a presidential statement. Until Lloyd's reprices, tanker insurance costs remain elevated and the strait stays commercially inaccessible regardless of the Brent spot move. Spot price and shipping-market reality pointed in opposite directions on Thursday, with the divergence persisting until a formal legal resolution of the conflict is certified.

What could happen next?
  • Consequence

    A sustained sub-$90 Brent reduces the economic pressure on Iran that Washington has cited as the blockade's primary coercive leverage, creating a narrow window in which both sides have an incentive to close a deal before the price recovers.

  • Risk

    Lloyd's of London's war-risk cover for Hormuz will not reprice until a UN Security Council resolution or government certification is issued. Until that threshold is met, tanker insurance costs remain elevated and the strait stays commercially inaccessible regardless of the spot Brent move.

    Short term · Reported
  • Opportunity

    South and Southeast Asian oil-importing economies, including India, Indonesia, Pakistan and Bangladesh, stand to gain approximately $1 billion per year per dollar of sustained Brent reduction at current consumption levels, partially offsetting the supply disruption costs they have absorbed since February.

Different Perspectives
Shipping and insurance underwriters
Shipping and insurance underwriters
Underwriters can price Houthi strikes because the group announces its targets, but an unclaimed drone at Damietta and a mandatory Iranian insurance scheme both deny them a pattern to price against. War-risk premiums are increasingly being set by the absence of a claimant, not the scale of the damage.
Jordan
Jordan
Azraq absorbed its fourth Iranian strike in seven weeks, again drawing no direct Jordanian retaliation, only an American one. Amman's exposure, hosting US basing without the Patriot density of Gulf allies, has not changed even as the war around it widens.
Houthi movement
Houthi movement
The Houthis' 20 July blockade of Saudi-linked shipping is the injury Riyadh's new 43-nation coalition directly answers, yet the group itself was never asked to join and remains outside every proposal on the table. Sanaa-aligned commentators call the coalition a paper reassurance for insurers rather than a deployable force.

Egypt confirmed the Damietta blaze was an attack, not an accident, on soil the war had never touched before. Cairo now faces an unclaimed threat to a facility supplying roughly 7% of its domestic gas, with no author to hold accountable and no pattern yet to defend against.
Oman
Oman
Muscat is running the only channel Iran will use, a voluntary Hormuz fee modelled on Malacca, but stayed out of Saudi Arabia's new naval coalition entirely. Oman's mediating leverage depends on treating Hormuz as shared and non-exclusive, the opposite of what Tehran is now demanding of it.
Iraq's Prime Minister
Iraq's Prime Minister
Al-Zaidi cancelled his first official Riyadh visit and convened the Coordination Framework, the coalition that keeps him in power and whose factions sit inside the PMF that Saudi jets just struck. He is caught between a five-year Saudi investment relationship and armed groups inside his own state he does not fully control.
