Updated 24 September 2026. Brent crude trades at $103.67 a barrel, up 0.57 percent on the day and 18.79 percent over the past month, according to TradingEconomics market data on 24 September. WTI is at $92.66. Verdict: the oil market has spent a week pricing the wrong tail. Prediction-market traders have put $74 million into the question of whether Iran keeps Kharg Island, the terminal that loads roughly 90 percent of its crude exports, and the answer they keep arriving at is yes, comfortably. The near-dated legs resolving 30 September and 1 October sit at about 1 percent. What the same board prices as genuinely uncertain is far duller and far more expensive: whether the Strait of Hormuz ever goes back to normal. That leg is 22 percent by year-end.
Key facts
- Brent: $103.67 (+0.57 percent), WTI: $92.66 (+0.55 percent) – TradingEconomics, 24 September 2026. Brent is up 51.17 percent year on year.
- Brent closed 23 September at $101.61, a 2.37 percent jump, after Iranian President Masoud Pezeshkian told the UN General Assembly that Iran will not permit freedom of navigation through Hormuz while US sanctions and the port blockade remain.
- Kharg Island handles about 90 percent of Iran’s oil exports and has roughly 7 million barrels per day of loading capacity (Argus Media explainer; Britannica).
- Polymarket’s “Kharg Island no longer under Iranian control” market has taken $74 million in total volume and $487,000 in the last 24 hours. It prices the year-end leg at 6 percent and the 30 September / 1 October legs at about 1 percent (Polymarket, checked 24 September).
- “Strait of Hormuz traffic returns to normal” prices at 1 percent by 30 September, 8 percent by 31 October, 13 percent by 30 November and 22 percent by 31 December, on $13 million of volume in the year-end leg alone.
- HSBC raised its 2026 Brent forecast to $90 from $80 on 10 September; its stalemate case is $120 (analyst Kim Fustier).
The $74 million question nobody is actually asking
Kharg Island is a 20-square-mile rock in the northern Persian Gulf that functions as the single point of failure for Iranian crude. Argus Media’s explainer on the terminal and Britannica’s entry both put its loading capacity near 7 million barrels per day, and reporting through the summer consistently placed roughly 90 percent of Iran’s seaborne exports through its jetties. Loadings resumed at the western terminal on 12 August after a 25-day shutdown caused by the Hormuz blockade, and between 19 and 21 September a VLCC capable of carrying up to 2 million barrels departed Iran’s Jask terminal in the Gulf of Oman – the workaround route that sits outside the Persian Gulf entirely.
That combination – a terminal that is both indispensable and militarily exposed – is why the Kharg market became one of the largest on Polymarket’s board. It is also why the pricing matters. Traders have put $74 million behind the question and settled on roughly a 6 percent chance that the island leaves Iranian hands by 31 December, and about 1 percent for the legs resolving next week. The adjacent island markets – Farsi, Hengam, Hormuz, Abu Musa, Greater Tunb – all sit at 1 percent for 1 October on volumes between $55,000 and $208,000.
The distinction the board is drawing is between striking a target and holding one. Iran’s export terminals have been hit and shut before. Occupying Iranian territory is a categorically different act, with a different escalation ladder attached, and the money says it is not happening this quarter. For an oil trader that is a specific and useful statement: the $150-a-barrel outcome that requires Iran’s export hub to change hands is priced at roughly one-in-sixteen by year-end, and roughly one-in-a-hundred by next Tuesday.
What the board says is actually uncertain
Move one market across on the same page and the confidence disappears. “Strait of Hormuz traffic returns to normal” is priced at 1 percent for 30 September, 8 percent for 31 October, 13 percent for 30 November and 22 percent for 31 December – and the year-end leg carries $13 million of volume, the second-largest pool in the complex after Kharg itself. Traders are not betting on a catastrophe. They are betting, with real conviction, on a grind.
Two related markets fill in the shape of that grind. “Iran-Oman Hormuz Management Agreement by 31 October” prices at 34 percent on $3 million, and “Iran charges Hormuz fees by 31 December” prices at 28 percent on another $3 million. Read together, that is a market assigning better than one-in-three odds to a negotiated transit regime in which the waterway reopens on terms – and on a toll. “Bab el-Mandeb Strait effectively closed by 31 December” sits at 18 percent on $15 million, a reminder that the Red Sea leg of the same problem has not gone away.
Two headlines from this week map directly onto those numbers. On 22 September a senior Iranian official told Reuters that Iran could reopen Hormuz within seven days if the United States eased military pressure and lifted the blockade on Iranian ports. On 23 September, at the UN General Assembly, Pezeshkian made the condition explicit, saying Iran cannot accept that everyone benefits from the waterway while its historic guardian is deprived by sanctions. That is not a threat to close the strait. It is an opening price for reopening it – which is precisely what a 34 percent management-agreement line and a 28 percent transit-fee line describe.
What that leaves in the price
HSBC’s Kim Fustier framed the same picture in flow terms on 10 September, raising the bank’s 2026 Brent forecast to $90 from $80. Her numbers: roughly 6 million barrels per day is currently moving through Hormuz, drifting toward about 8 million by end-2026 and 9.5 million by mid-2027, against 19 to 20 million before the war. HSBC does not expect the market to rebalance until around the middle of 2027, and describes a disrupted “new normal” in which the strait is neither closed nor open but persistently impaired. The bank’s stalemate case – diplomacy fails, flows stay constrained – is $120.
Goldman Sachs has warned separately that prices could reach $120 if attacks on Middle East shipping intensify. Citi’s April work put a $150 tail on the scenario in which flows stay disrupted, assigning roughly 30 percent to its bull case at the time. Bank of America has been the conservative outlier, at $83 for the second half of 2026.
With Brent at $103.67, the market is already trading above every published base case except the stalemate ones. That is the uncomfortable part: spot is not pricing HSBC’s $90 world, it is pricing something between the base case and the stalemate, and it got there mostly on the strength of a UN speech.

Scenarios into year-end
| Case | Brent | vs spot ($103.67) | Anchor |
|---|---|---|---|
| Bear | $90 | -13.2 percent | HSBC’s published 2026 base case, raised from $80 on 10 September (Kim Fustier). Requires the fragile US-Iran understanding to hold and Hormuz flows to drift toward 8m bpd on schedule. The Polymarket board gives the “traffic returns to normal by 31 December” leg 22 percent. |
| Base | $104 | flat | The board’s own modal path: no change of control at Kharg (about 94 percent by year-end), no return to normal traffic (78 percent), and a one-in-three chance of a negotiated transit regime with fees. Impaired, open, expensive. |
| Bull | $120 | +15.8 percent | HSBC’s stalemate case and Goldman Sachs’ escalation warning converge here: diplomacy fails, shipping attacks intensify, flows stay near 6m bpd. Citi’s separate $150 tail sits above this and requires a supply event at an export terminal – the outcome the Kharg market prices at 6 percent. |

Quick take
Brent at $103.67 is carrying a war premium for a war outcome that the deepest prediction market on the subject prices at roughly 1 percent this week. What is not priced out is the boring version: a strait that stays half-shut into 2027, flows at 6 million barrels a day against a pre-war 19 to 20 million, and a one-in-three chance the reopening comes with a toll attached. If you are long oil on the Kharg headline, you are long a 6 percent event. If you are long oil on Hormuz staying broken, the board is on your side at 78 percent – and so is HSBC’s mid-2027 rebalancing date.
FAQ
What is Brent crude trading at today?
Brent is at $103.67 a barrel as of 24 September 2026, up 0.57 percent on the day, per TradingEconomics. WTI is at $92.66. Brent is up 18.79 percent over the past month and 51.17 percent year on year.
Why does Kharg Island matter to the oil price?
Kharg is the loading terminal for roughly 90 percent of Iran’s crude exports, with about 7 million barrels per day of loading capacity. A loss of the terminal would remove Iran’s primary route to the seaborne market almost overnight, which is why it is the single most-traded geopolitical question on Polymarket’s Iran board.
What odds is Polymarket giving on Kharg Island?
About 1 percent for the legs resolving 30 September and 1 October, and 6 percent for a change of control by 31 December, on $74 million of total volume and $487,000 traded in the last 24 hours, checked 24 September 2026. Odds move continuously – verify at the source before acting on them.
When will the Strait of Hormuz reopen?
Nobody knows, and the market says not soon. Polymarket prices a return to normal traffic at 1 percent by 30 September, 8 percent by 31 October, 13 percent by 30 November and 22 percent by 31 December. HSBC does not expect the oil market to rebalance until around mid-2027. A senior Iranian official told Reuters on 22 September that Iran could reopen the strait within seven days if the US eased military pressure and lifted its port blockade.
What are analysts forecasting for Brent?
HSBC raised its 2026 Brent forecast to $90 from $80 on 10 September, with a $120 stalemate case. Goldman Sachs has warned of $120 if shipping attacks intensify. Citi’s April work carried a $150 tail. Bank of America has been at $83 for the second half of 2026. Spot is currently above all of the base cases.
Could Brent reach $150?
Citi has put that number on the scenario where Hormuz flows stay disrupted. Mechanically it requires a genuine supply event rather than a risk premium – most plausibly an interruption at an export terminal. The prediction market prices a change of control at Kharg at 6 percent by year-end, which is the closest available read on how likely traders think that specific path is.
How much Iranian oil is still moving?
Loadings resumed at Kharg’s western terminal on 12 August after a 25-day shutdown. Between 19 and 21 September a VLCC able to carry up to 2 million barrels departed the Jask terminal in the Gulf of Oman, Iran’s route that bypasses the Persian Gulf. HSBC estimates roughly 6 million barrels per day is currently transiting Hormuz overall, against 19 to 20 million before the war.
