The Strait of Hormuz is a narrow waterway between Iran and Oman, barely 33 kilometers wide at its narrowest point. Through this sliver of ocean passes roughly 20% of the world's daily oil supply — approximately 21 million barrels per day. Saudi Arabia, Iraq, Kuwait, the UAE, and Qatar all depend on it for their crude exports. When tensions flare in the strait, oil markets react instantly, and the ripple effects reach every corner of the global economy.
The latest escalation began in late April 2026 when Iranian Revolutionary Guard Corps naval vessels conducted live-fire exercises within 15 nautical miles of the strait's shipping lanes — the closest such exercises in over three years. Two weeks later, Iranian officials warned that any expansion of US sanctions enforcement in the Persian Gulf would be met with "proportionate measures to safeguard sovereignty." The language was deliberately vague. Markets hate vague.
Brent crude has risen 14% since the exercises, from $72 to $82 per barrel. WTI has tracked closely, moving from $68 to $77. But the price of crude is only part of the story. Options volatility, futures curve structure, and cross-commodity spreads are telling a more nuanced tale about how professional traders are positioning for what might come next.
The current tensions did not emerge in a vacuum. Since 2023, the US has gradually tightened sanctions enforcement on Iranian oil exports, targeting the network of intermediaries and "dark fleet" tankers that have allowed Iran to sell roughly 1.5 million barrels per day to China and other buyers despite sanctions. Each enforcement action draws a response from Tehran, and the cycle of escalation has been intensifying.
For oil traders, the critical question is not whether Iran will close the strait — that remains a low-probability, high-consequence scenario. The question is how much "risk premium" the market should price in. Risk premium is the extra cost baked into the oil price to account for the probability of supply disruption. Estimates from commodity strategists range from $8 to $15 per barrel currently embedded in the price.
History provides some guidance. In 2019, when Iran seized a British-flagged tanker in the strait, Brent spiked 4% in a single session. In September 2019, the Abqaiq-Khurais attack on Saudi oil infrastructure — the largest single disruption in oil market history — sent Brent up 15% overnight. Both events resolved without sustained supply cuts, and the risk premium faded within weeks. But the precedent is clear: events in or near the strait can move crude by $5-$15 per barrel in hours.
Professional oil traders are deploying several strategies in response to the current tensions, each reflecting a different view of how the situation might evolve.
Call option buying. The most direct hedge against a supply shock is to buy out-of-the-money call options on Brent or WTI crude. These options pay out if oil spikes above a certain price — say, $100 per barrel — and cost relatively little if the spike never materializes. Open interest in Brent $100 calls for September 2026 expiry has tripled since mid-April, according to ICE data. This is classic "tail risk" hedging: paying a small premium for protection against a low-probability, high-impact event.
Calendar spreads. The futures curve for Brent has shifted into steep backwardation — near-term prices are higher than prices for delivery months further out. This reflects the market's view that the risk is concentrated in the short term. Some traders are exploiting this by selling near-month contracts and buying deferred ones, betting that the backwardation will flatten as tensions ease. Others are doing the opposite, betting that a crisis will deepen backwardation further.
"You don't trade the Strait of Hormuz by guessing the headline. You trade the structure. Backwardation, volatility skew, and the crack spread tell you more than any intelligence briefing."

The "crack spread" is the difference between the price of crude oil and the price of refined products like gasoline and diesel. A Hormuz disruption would affect crude supply but not refining capacity, potentially widening the crack spread as refiners bid up crude while product demand remains stable. Some traders are positioning for exactly this scenario by going long crack spreads — buying crude and selling product futures simultaneously.
Energy equity plays. Canadian energy stocks — particularly oil sands producers with no direct exposure to Middle Eastern shipping — stand to benefit from elevated crude prices. Companies like Suncor, Canadian Natural Resources, and Cenovus Energy are natural beneficiaries of any sustained supply disruption. Traders are buying call options on these equities as a leveraged play on higher oil prices, with the added benefit that Canadian producers face no direct operational risk from Hormuz tensions.
Canada's oil industry occupies a unique position in the Hormuz equation. As the world's fourth-largest oil producer, with virtually all exports going to the US via pipeline, Canada is insulated from shipping disruptions in a way that Persian Gulf producers are not. If Hormuz is disrupted, Canadian heavy crude — typically priced at a discount to WTI — would likely see its differential narrow or even flip to a premium, as US refiners scramble for non-seaborne supply.
The Western Canadian Select (WCS) discount to WTI has already narrowed from $14 per barrel in March to $10 in mid-May. A genuine Hormuz disruption could push WCS to parity or premium, a scenario that last occurred during the Abqaiq attack in 2019 (briefly) and during the peak of COVID recovery demand in 2022.
For the Canadian dollar, higher oil prices are broadly supportive. The loonie has a well-documented positive correlation with crude, and each $10 per barrel increase in WTI historically translates to approximately 1.5-2 cents of CAD strength against the USD. Forex traders are positioning for this via long CAD/JPY and short EUR/CAD trades — both of which benefit from higher commodity prices and Canadian dollar strength.
Not every trader has the capital or risk appetite to trade crude oil futures directly. But the Hormuz situation affects portfolios in ways that even retail investors should consider.
The most important thing for any trader or investor during a geopolitical crisis is to avoid panic positioning. The Strait of Hormuz has been a flashpoint for decades. Most escalations de-escalate. Markets overshoot on fear and then correct. The disciplined approach is to define your risk before the crisis peaks — not after the headline has already moved the market. Position sizing, stop losses, and a clear thesis are worth more than any geopolitical prediction.
