Strait of Hormuz Mine Claims: Iran Says Three Tankers Caught Fire, What It May Mean for Oil at the Weekly Open
Iran's military says three oil tankers hit naval mines in the Strait of Hormuz on 13 and 14 November 2026 and caught fire. These are claims. None of the ships has been named, and Reuters said it could not immediately verify the reports. The US military disputes Iran's mine claims and says the main shipping routes are clear, FinanceFeeds reported on 15 November.
The first market test comes on Sunday evening, before Monday. Brent crude futures reopen at 18:00 ET (23:00 UK) on 15 November. Brent settled at $95.84 on Friday 13 November, after a second weekly loss. Reference levels quoted by FinanceFeeds put a bull case near $98 and a bear case near $91. They are reference points only and may fail. Last Sunday, a similar weekend mine claim produced only a brief dip at the open.

The Short Answer: What Happened in the Strait of Hormuz and Why It Matters for Oil
Here is the situation in brief, as of Sunday morning, 15 November 2026.
- Iran's Revolutionary Guards Navy (IRGC Navy) says two tankers hit mines late on Friday 13 November.
- Iran's regular navy says a third tanker hit a mine east of the strait on Saturday morning.
- Independent confirmation of any of the three incidents is still missing.
- The US military says the internationally recognised transit routes were cleared of mines.
- Oil futures reopen on Sunday at 18:00 ET, which is 23:00 in the UK.
- Brent starts the week at $95.84, about $2.50 below the previous Friday.
The market question is simple. Will traders treat the claims as a real supply threat, or as another unconfirmed headline? Since late October, similar Iranian claims appear to have moved prices only briefly. Prices have tended to give back those gains when confirmation did not follow.

Iran Says Three Tankers Hit Mines: The Claims in Detail
The IRGC Navy claim on Friday night
Iran's state media carried the first statement on Friday evening, UK time. It was already Saturday in Tehran. ThePrint carried a Reuters report that quoted IRNA. In it, the IRGC Navy described "two violating tankers" that tried to pass through a prohibited route. It said both exploded and caught fire.
Iranian outlets added that one of the two ships was a supertanker. They also said the vessels had switched off their tracking systems. These details come only from the Iranian side.
The third tanker on Saturday morning
A separate statement followed from Iran's regular navy. It said a tanker east of the strait, in what it called an "unsafe and prohibited area", ignored warnings. The navy said the ship "caught fire and stopped after hitting a naval mine", The Tribune reported.
Source: The Tribune, House of Saud. All details are Iranian military claims.
What is still unknown
Several basic facts are missing. Each one matters for how far the market may trust the story.
- The names of the ships are unknown.
- The flag states and owners are unknown.
- The cargoes on board have not been disclosed.
- Satellite images of fires have not been published.
- Statements from shipowners have not appeared.
Are the Hormuz Mine Claims True or False?
The case for caution
The US Central Command (CENTCOM) has rejected earlier claims of this kind. On 28 October it said the main routes "have been cleared of sea mines by U.S. forces and remain so", as Middle East Eye reported. CENTCOM had announced the end of its mine clearing on 27 August, Ynet News noted.
Analysts quoted by Ynet News say they have seen little sign that Iran has laid new mines. They suspect that some ships are hit by drones or missiles, with the damage then blamed on mines. The same report cited an October case of a small boat attaching magnetic mines to a tanker.
As of Saturday morning, CENTCOM had not issued a statement on the 13 November claims specifically, House of Saud noted.
Why the risk is still real
Some attacks on ships have been confirmed. On 11 November, the UK Maritime Trade Operations centre (UKMTO) reported a vessel hit by an "unidentified projectile". It was about 14 nautical miles north-west of Ras Al-Khaimah, with a fire in its engine room. The crew was evacuated, MarineLink reported.
The same report cited the Washington Institute, which counted 37 attacks in October. That was the highest monthly total since the war began in late February. At least 10 ships were hit in the first 10 days of November.

Oil Market Starting Point: Where Brent and WTI Closed on Friday
Friday settlements
Brent closed the week with a tiny gain on the day. It still posted a second weekly loss. FinanceFeeds reported that Brent settled at $95.84, up 2 cents. It traded at $96.67 at 14:14 GMT, up 85 cents, before giving most of that back.
WTI crude settled at $88.56, down 0.2%. That leaves the gap between the two benchmarks at about $7.28 a barrel.

A volatile week in key settlements
The week was far from calm. Brent fell sharply on Monday after news of mediation by Qatar. It then bounced on Thursday after fresh Iranian claims about four tankers.
Source: Nation Thailand, FinanceFeeds. Wednesday 11 November is not shown, and the Tuesday move is calculated. Past performance is not a reliable indicator of future results.
The weekly fall to 6 November was about 16%, an unusually large move. Nation Thailand called it the sharpest weekly drop since the start of the COVID-19 pandemic. The Energy Brief described it as the worst since 2022.
When Do Oil Futures Open? Timing for the Sunday Session
Many readers expect oil to react on Monday morning. In practice, the first reaction comes on Sunday evening. Electronic trading in Brent and WTI futures restarts at 18:00 ET on Sunday.
Times calculated from the 18:00 ET restart. UK clocks are on GMT in November.
Why the first hour can be unusual
Liquidity tends to be thin when oil futures reopen on a Sunday. Fewer orders are in the market, so a small number of trades can move the price. Gaps between the Friday close and the first Sunday quote are common after weekend news. Spreads on related CFDs can also be wider than usual at that time.
Readers new to the topic can find more on why prices jump in thin conditions in the Admirals guide to market volatility.
What Happened at Last Sunday's Open: A Useful Precedent
The weekend of 7 and 8 November offers a close comparison. Iran also claimed mine strikes on tankers that weekend. Brent did not gap higher.
According to The Energy Brief, Brent touched $96.57 in the first minute of trading on Sunday 8 November. It then recovered most of that drop, and the same report quoted it at $97.66, down 0.67% from Friday, without a time stamp.
Source: The Energy Brief. Past performance is not a reliable indicator of future results.
One precedent proves little. Markets can treat a third or fourth claim differently from the first one. A named ship or a photo of a burning hull could change the reaction quickly.
Strait of Hormuz Shipping: Traffic and Insurance Costs
Traffic is still far below pre-war levels
Before the war, about 130 to 140 vessels crossed the strait each day. In the week to 14 October, about 254 transits were counted. That is roughly 36 a day, or about 70% below pre-war traffic, House of Saud reported. More recently, FinanceFeeds cited UKMTO data showing traffic about 65% below pre-war levels.
Source: House of Saud, NPR, FinanceFeeds. Past performance is not a reliable indicator of future results.
Strait of Hormuz insurance: the war risk premium
Insurance is one of the clearest signs of how shipowners see the danger. Before the conflict, war-risk cover for a Hormuz transit cost roughly 0.25% of a ship's hull value. It now runs at about 3% to 10% per transit, according to broker Marsh as cited by House of Saud.
For a supertanker with a hull value of around $100 million, that range equals roughly $3 million to $10 million for one voyage. In July, Al Jazeera quoted Hormuz war-risk costs of 7.5% to 10% of hull value.
Source: House of Saud, Al Jazeera.
A key signal to watch this week is any move by insurers to suspend or reprice cover. As of Saturday, cover was still available, though at a very high cost.
The main test this week is confirmation. A named ship or an owner statement could add a premium to Brent. A quick rebuttal could see that premium fade, as it did on 8 November.
Supply and Demand: Why the Backdrop Has Turned Softer
The IEA sees a surplus
The mine claims land in a market that has been easing. The International Energy Agency (IEA) said on 13 November that the market moved into surplus in October. It was the first surplus since the war began, The National reported.
Gulf exports outside Oman reached 18.4 million barrels a day in October. That is still 26% below pre-war levels. The IEA expects 2026 demand to fall by 2.7 million barrels a day to 102.3 million. It also described diesel supply as being in "severe tightness", The National added.
OPEC+ and US supply
Output from OPEC rose by 1.38 million barrels a day in October to 22.87 million, a Reuters survey found, as cited by Nation Thailand. JPMorgan estimated a global surplus of about 1.4 million barrels a day for that month.
In the United States, crude stocks rose by about 4.66 million barrels in the week to 6 November. It was the biggest weekly build since August, Trading Economics reported. Saudi Arabia also reported a 26% rise in its October production.

Factors That Could Support or Weigh on Oil This Week
Both sides of the market have solid arguments. The table below sets them out next to each other.
Source: FinanceFeeds, The National.
The geopolitical risk premium
Analysts often call the extra price linked to conflict a geopolitical risk premium. Here it seems to rise on each claim and fade when the claim is not confirmed. The pattern since late October fits that view. Brent touched about $118 in late October, on a contract that has since expired, as the Kitco (Reuters) note recorded. The current front month sits around $22 below that high, so the comparison is approximate.
Brent Technical Analysis: The Chart Picture
Brent key levels
A Reuters technical analyst, writing on 10 November, said the climb since July looked finished for now. The note, published by Kitco, mapped the levels below. Price levels are reference points only and may fail.
Source: Kitco (Reuters), FinanceFeeds. Past performance is not a reliable indicator of future results.
How the open may interact with these levels
Brent settled just above its 40-week average of $95.27. Support around $93.84 to $94.07 sits close below. A gap down through that zone may bring $91.49, the 10 November low, back into focus. A gap up would meet the $98.32 area first. Above that, the $100 to $101 band has been described as the line that could challenge the downtrend.
Illustrative Scenarios for the Weekly Open
The scenarios below are illustrative. They use the reference levels quoted by FinanceFeeds. They are not predictions, and the market may follow none of them.
Source: FinanceFeeds, Kitco. Forecasts are not a reliable indicator of future performance.
The bullish case
Confirmation would be the main trigger. Markets may react more strongly if damage to a tanker is verified. A further drop in transits could add to that.
The bearish case
A firm rebuttal could push the focus back to supply. The IEA surplus and rising OPEC output would then take centre stage. A further build in US stocks on Wednesday could add weight.
Brent Forecast: What the Big Forecasters Expect
Longer-range forecasts sit above the current price. That gap is worth keeping in mind. It shows how much uncertainty surrounds the outlook.
Source: Oil & Gas Journal, 5paisa, The National. Forecasts are not a reliable indicator of future performance.
Goldman Sachs also set out a severe scenario. It assumes Gulf output averages 3.5 million barrels a day below 2025 levels in 2027. In that case, the bank sees Brent averaging about $130, 5paisa reported. The headline of the same report mentions $140.
Brent Price History: The Five-Year Picture
Recent swings look large, and the longer view adds context. Brent fell for three years in a row from 2023 to 2025. It then rose by about 57% in 2026 to 13 November, from a low base of $60.85. That rally includes the war shock of 2026 and the sharp fall from the October high.

Brent vs WTI and Related Markets
The Brent-WTI spread
Brent is the global seaborne benchmark. WTI is the main US benchmark. Gulf supply risk is often seen as affecting Brent more, since more Gulf crude is priced against it. The spread stood at about $7.28 on Friday.
USDCAD and other assets traders watch
Oil moves can spill into other markets. The Canadian dollar has often been linked to crude, since Canada is a large oil exporter. Readers following that link may watch USDCAD alongside Brent.
Qualitative overview for illustration only.
The Fed adds another layer
The Federal Reserve raised rates in September 2026, its first hike since July 2023, InvestmentNews reported. Higher rates and a firmer dollar tend to weigh on oil, FinanceFeeds noted. The next Fed decision is due on 9 December, according to the Federal Reserve calendar.
Oil Calendar: Key Dates in the Weeks Ahead
Source: World Oil, FinanceFeeds, Federal Reserve. Dates may change.
The OPEC+ meeting on 29 November may matter more than the mine claims over the month. Jorge Leon of Rystad Energy called it "the much more important test", FinanceFeeds reported. Weekly data and economic releases are listed in the Admirals economic calendar.
What Traders Often Watch After Weekend Headlines
Traders handle news-driven opens in many ways. The points below describe common habits. They are general information and should not be read as a recommendation.
Checklist for the first hours
- Many traders check whether any ship has been named by a credible source.
- Some watch UKMTO notices for confirmed incidents.
- Others follow statements from CENTCOM.
- Insurance news is a further signal that many follow.
- Some compare the first Sunday quote with the Friday settlement of $95.84.
- Position sizes are often kept smaller when liquidity is thin.
Illustrative overview based on the scenario triggers reported by FinanceFeeds.
Managing risk around gaps
Weekend gaps can jump past stop-loss levels. A stop order may then be filled at a worse price than planned. Leverage magnifies losses as well as gains. Traders often manage risk by sizing positions with the gap risk in mind.
How to Trade Oil CFDs: Points to Consider
A crude oil CFD lets a trader speculate on price moves without owning barrels. Admirals offers CFDs on commodities such as crude oil and natural gas. The range is listed on its commodity CFD page. The Admirals guide on how to trade crude oil CFDs explains the basics.
General product information. CFDs carry a high risk of losing money.
Oil CFDs can be traded on platforms such as MetaTrader 5. A demo account uses virtual funds, and results may differ from live trading. Some newcomers use one to practise before risking real money.
