Iran Attacks Bahrain, Hormuz Mines: What Next for Oil Prices
Iran says it attacked a US base in Bahrain and 7 ships hit mines in Hormuz. What's confirmed, Brent at $95.84 and what to expect for oil prices Monday.
In short: Iran's Revolutionary Guards said on Sunday 15 November 2026 that they launched six drones at a US air-defence radar at Riffa helicopter base in Bahrain, and the IRGC Navy claims seven ships have hit mines in the Strait of Hormuz within 24 hours. Bahrain says it intercepted the attacks, and no maritime authority has confirmed the mine strikes. Brent settled on Friday at $95.84 a barrel, and that level faces its first test when trading reopens on Monday.
Updated Sunday 15 November 2026, 13:45 CET (Madrid time). Method: we only treat as confirmed what Bahrain, US Central Command (CENTCOM) or the UKMTO and JMIC maritime centres confirm; everything else is presented as a claim.
Iran's attack on US base in Bahrain: what happened this weekend
On Sunday morning, 15 November (Gulf time), Bahrain's Interior Ministry twice told residents to head to the nearest safe location. It was the first nationwide alert in months (the previous one was in September), according to The National. The Bahrain Defence Force says its air defences intercepted and destroyed "a number of Iranian aerial attacks".
Iran's Islamic Revolutionary Guard Corps (IRGC), for its part, says six drones struck a US air-defence radar at the Riffa helicopter base in Bahrain, the country that hosts the US Fifth Fleet, and describes it as a "second phase" of retaliation. Neither Washington nor Manama has confirmed any damage. On Friday 13 November, CENTCOM had already rejected a similar claim, saying it shot down two Iranian drones with no injuries or damage, according to CBS News.
The mines: seven incidents according to Iran, none confirmed
On Saturday night, the IRGC Navy said two oil tankers exploded and caught fire after hitting mines on an "unauthorised" route south of the strait, and that two more turned back after its warnings. Adding those to the incidents announced since Friday night, the IRGC Navy now puts the total at seven in 24 hours, according to Investing.com. It has given no names, flags or owners, and the US says it has cleared the main shipping lanes of mines.
Are the Hormuz mine claims credible? Iran's track record
This is not the first time. Between 18 July and 20 October alone, the IRGC announced eight times that ships had struck mines in Hormuz, almost always without naming them. None of those mine-strike claims has been independently verified, although projectile attacks have been confirmed, according to a tally by gCaptain:
| Date of Iran's claim | What Iran said | Response |
|---|---|---|
| 18 July | Two oil tankers caught fire in a minefield | CENTCOM: false |
| 31 August | A supertanker struck two mines | CENTCOM: "No ships have hit mines" |
| 14 October | A container ship struck a mine | JMIC and CENTCOM: hit by a projectile, not a mine |
| 17 October | Two supertankers struck mines | JMIC: "there is no substantiation to these claims" |
| 14–15 November | Seven incidents in 24 hours | Unconfirmed |
Unverified does not mean risk-free: projectile attacks have been confirmed, and the JMIC keeps its threat level at "severe". For the market, the distinction matters. A claim without evidence moves the price for a few hours; a named, damaged vessel can reshape the risk premium for days.
Why it matters: Hormuz is still oil's chokepoint
The war began on 28 February 2026 with US and Israeli strikes on Iran. Since then, Tehran has required ships to obtain its permission to cross the strait, the US has blockaded Iranian ports, and Iran has tied reopening the waterway to an end to that blockade and to seven conditions for a deal.
Tensions at sea have not eased. Verisk Maplecroft counted 36 confirmed attacks on merchant ships in the Persian Gulf, the Strait of Hormuz and the Gulf of Oman in October, the highest monthly total of the war, according to Bloomberg (via Rigzone). On the political front, Donald Trump wrote on Thursday 12 November that "We don't need a deal with Iran" and told Vice President JD Vance to focus on domestic issues rather than the negotiations, according to CBS News. We covered that in Trump, Iran and Hormuz: why oil prices are falling in November.
Brent oil price: where crude stands ahead of the open
Brent settled on Friday 13 November at $95.84 a barrel and WTI at $88.56. It was a second straight weekly loss, of around 2.5%, as the International Energy Agency (IEA) expects the market to be in surplus this quarter for the first time since the war began. The weekend attacks happened while futures markets were closed.
| Benchmark | Figure | Source |
|---|---|---|
| Brent, Friday 13 Nov settlement | $95.84/bbl | Bloomberg |
| WTI, Friday 13 Nov settlement | $88.56/bbl | Bloomberg |
| Brent (January contract), 30 October settlement | $113.43/bbl | Nation Thailand |
| Fall in January Brent since 30 October | -15.5% | Our calculation |
| Brent before the war (late February) | about $72/bbl | CBS News |
| Gulf exports (excluding Oman) vs pre-war | -26% | IEA, via CBS News |
The January contract settled at $113.43 on 30 October, according to Nation Thailand, after a 13.6% gain over the month. In two weeks it has given back much of that rally: the IEA says supply exceeded demand in October and global inventories grew by 1.7 million barrels a day, though it warns that attacks on shipping are the main risk. Sid Perkins, chief executive of Snapper Creek Energy, said on Friday that Hormuz and Washington's tougher tone give the market reason to add a geopolitical risk premium back into crude.
The Thursday 12 November precedent
There is a recent precedent for how the market might react. On Thursday 12 November, after Trump's post and fresh claims of attacks on tankers, Brent rose 3.3% to $95.82; the next day it settled virtually flat. The reaction was fast, but it did not hold without new, confirmed facts.
What it means for traders and investors
The first test comes when futures reopen: CME's WTI and ICE's Brent resume trading at around midnight CET on Sunday night. These are the three scenarios we are watching, without taking any of them for granted:
- Confirmed escalation. If damaged ships are named, verified images emerge or damage at Riffa is confirmed, the risk premium would likely return and crude could gap higher at the open. The signal would be Brent holding above Friday's settlement after the Asian session, not just in the first minute.
- Unconfirmed claims. That is what happened with previous claims. If nobody verifies the mines, the market may turn back to the IEA's surplus, as it did on Friday 13 November.
- De-escalation. Trump said he could halt attacks if there are no new provocations. Any diplomatic gesture would shrink the premium.
Opening gaps are dangerous with leverage: a stop-loss does not guarantee your exit price if the market gaps past it at the open. Before trading oil CFDs, size your position with the position size calculator and check the margin required. Leveraged trading can cost you more than you expect; read our risk warning.
What to watch this week and when
- Sunday night / Monday 16 November: futures reopen and Asian trading begins; confirmation or denial of the incidents by UKMTO, JMIC and CENTCOM.
- Wednesday 18 November: weekly US crude inventories from the Energy Information Administration (EIA), usually at 10:30 New York time (16:30 CET).
- 18–19 November: APEC summit in Shenzhen, China. According to Investing.com, Trump is expected to discuss the war there with Xi Jinping.
- All week: Oman's plan with Iran for a joint control system for the strait, and the United Nations' call to let fertiliser shipments through, with fertiliser prices up around 30%, according to CBS News.
Frequently asked questions
Did Iran attack a US base in Bahrain?
The Revolutionary Guards say they did: six drones aimed at a radar at Riffa helicopter base on 15 November. Bahrain says it intercepted the attacks, and neither the US nor Bahrain has confirmed any damage. It is an Iranian claim without independent verification.
What has the United States said?
Nothing so far confirming damage from Sunday's attack. On Friday 13 November, CENTCOM said it shot down two Iranian drones with no injuries or damage, and Washington maintains it has cleared the strait's main shipping lanes of mines. Trump is keeping the naval blockade of Iranian ports in place.
Is the Strait of Hormuz closed?
Not completely, but passage is heavily restricted: Iran demands permission to cross and attacks ships that do not ask, while the US blockades Iranian ports. The IEA estimates that Gulf exports, excluding Oman, remain 26% below pre-war levels.
What will happen to oil prices on Monday?
Nobody knows in advance. Brent closed on Friday at $95.84, and the first post-attack price will come when futures reopen, at around midnight CET on Sunday night. On Thursday 12 November, a similar situation produced a 3.3% jump that did not hold the next day.
