The Last Tankers Have Arrived
The oil world just crossed a critical threshold that most people haven't noticed yet.
The IEA's executive director Fatih Birol warned in early April that in March there were still cargo ships carrying oil that had transited through the Strait of Hormuz before the war broke out, they were still arriving at ports. "In April," he said, "there is nothing."
Those last tankers have now docked. The pipeline of pre-war Gulf crude is empty. What countries are burning through right now are strategic reserves, and those have a hard bottom.
The UK holds roughly 90 days of strategic reserves. Europe has approximately six weeks of jet fuel remaining. China entered the conflict in the strongest position globally, with nearly 1.4 billion barrels stocked away, but even Beijing has begun drawing down.
The uncomfortable math: refilling inventories after a prolonged closure will require an additional 1.8 million barrels per day above baseline demand for a full year — and that assumes the strait reopens soon. It hasn't.
What this means: The supply crunch is not coming. It's here. The next 30-60 days will determine whether a negotiated settlement arrives in time or whether rationing becomes a reality in Europe and parts of Asia. Watch inventory data and tanker movements closely they're the leading indicator everyone else is missing.
MARKET SNAPSHOT
The US Energy Information Administration projects Brent crude averaging around $115/barrel in Q2 2026. Goldman Sachs estimates Brent hovering around $80/barrel by year end, roughly $20 higher than their pre-conflict forecast.
Brent Crude: ~$100–105/barrel
WTI: ~$95–100/barrel
Jet Fuel: Nearly double pre-war levels at ~$200/barrel
WCS (Western Canada Select): ~$80–88/barrel — trading at roughly $16 discount to WTI
Natural Gas: Severely disrupted, LNG flows from Qatar remain constrained
Price outlook: Markets have largely priced out the worst case $200/barrel scenario following Trump's ceasefire extension, but the Strait of Hormuz remains functionally closed and as Goldman's Daan Struyven noted, "you can't draw inventories forever."
THE INSURANCE WALL — Why A Ceasefire Doesn't Reopen The Strait
This is the number most analysts are glossing over and it explains why political announcements keep failing to move physical oil flows.
Before the conflict, typical war risk insurance rates for the Strait of Hormuz were 0.15% to 0.25% of hull value for a one-week policy. Since the conflict began, quotes have reached as high as 5% to 10% of hull value. That is a 4,000% increase.
In the days immediately before the February 28 strikes, premiums had already risen from 0.125% to between 0.2% and 0.4% an increase of a quarter million dollars per transit for a Very Large Crude Carrier. That was the warning signal the market gave before a single shot was fired.
Lloyd's Market Association has expanded its "high-risk" designation to cover the entire Persian Gulf. In the weeks prior to the war, an average of 178 ships transited the Strait daily. Traffic has since reduced by approximately 95%.
Current rates sit at 2-6% of hull value still 10-40 times pre-war levels. Insurers are now pricing transits on a case-by-case basis requiring a ship to be pointed at the Strait with engines running before they'll quote a price, valid for just 48 hours.
The bottom line: even if Iran verbally reopens the Strait tomorrow, independent tanker operators will not move until insurance premiums normalize and premiums will not normalize until sustained, verified safe passage is demonstrated over weeks not days. Watch premium rates, not political statements, as your leading indicator.
GEOPOLITICAL PULSE - Ceasefire Extended, Crisis Unresolved
Trump indefinitely extended the two-week ceasefire with Iran on Tuesday, just hours before it was set to expire. Markets largely shrugged.
A second round of US-Iran talks in Islamabad is being arranged, though it remains unclear who will lead the Iranian delegation. The ceasefire extension came after the US Navy seized an Iranian cargo ship in the Gulf of Oman, which Iran called a direct violation of the truce.
Iran maintains effective control over the Strait of Hormuz through two IRGC-controlled transit corridors. Maritime insurance premiums remain at 2–5% of hull value, keeping most independent tanker operators out of the strait regardless of political declarations.
Bottom line: A ceasefire announcement is not the same as open water. The strait is still closed for practical purposes. Until insurance premiums normalize and tanker operators return voluntarily, no political statement changes the supply math.
INCIDENT WATCH — Eight Refineries in 60 Days
At least eight significant industrial incidents have struck oil refineries, processing units, and upstream sites across multiple continents between February and April 2026 — roughly one major incident every seven to eight days.
Valero Port Arthur, Texas — March 23: A major explosion and fire at one of the US's largest refineries processing 380,000–435,000 barrels per day. The blast shook homes miles away and forced multiple unit shutdowns for several days.
Viva Energy Geelong, Australia — April 15-16: A gas leak ignited a major fire at one of Australia's only two remaining refineries, supplying roughly 10% of national fuel. Petrol output fell to 60% of normal capacity.
Pemex Dos Bocas, Mexico — April 9: The fourth significant safety incident in 23 days at Mexico's flagship new refinery. A petroleum coke warehouse fire required over 150 specialized personnel to contain.
Russia's Tuapse Refinery — April 22: Ukrainian drone strikes ignited fires at the Tuapse refinery, with hundreds of firefighters deployed to contain the blaze.
The Turnaround Problem Nobody Is Talking About
Here's what the headlines are missing — and this comes straight from inside the industry. Refineries run on planned maintenance cycles called turnarounds, typically scheduled every 3-5 years. They are major multi-week shutdowns involving hundreds of contractors, significant capital expenditure, and extensive equipment overhauls.
With margins currently surging due to the supply crunch, operators are under enormous pressure to keep units running. S&P Global's Kurt Barrow noted that operating rates before the crisis were in the mid-70% range "suddenly everything's flat out." That means deferred maintenance, pushed turnarounds, and aging equipment running beyond its intended service window.
The Geelong fire is a direct consequence of exactly this dynamic. Union officials noted that some maintenance had been deferred and the refinery was operating at maximum capacity running a 1950s-era facility flat out in a global supply crisis.
The industry will pay for these deferred turnarounds. When the conflict resolves and margins normalize, expect a wave of planned and unplanned shutdowns across 2026 2027 as operators catch up on overdue maintenance. That has its own supply implications and investors should be watching for it.
While the rest of the world scrambles for supply, North America finds itself in an unexpected position of relative strength though it's complicated.
Alberta's Windfall: Iranian and Iraqi heavy sour grades compete directly with Western Canadian Select. Restrictions on Middle Eastern supplies have tightened global sour spreads by early March the WCS-to-WTI discount had narrowed to $12.40/barrel. Tighter spreads mean fatter margins for Alberta producers. Alberta's oil output averaged 4.2 million barrels per day over the first two months of 2026 the highest on record, a 3.3% increase over the same period last year.
The Pipeline Constraint: Canada's Trans Mountain pipeline is nearly full for April a utilization record since completion in 2024. The bottleneck isn't production it's getting the barrels to market fast enough. Pipeline capacity remains the ceiling on how much Canada can capitalize on the current price environment.
Alberta's Fiscal Reality: Alberta Finance Minister Nate Horner has said Alberta needs $74 US/barrel to balance its budget. With oil well above that threshold, the conflict is quietly helping address what was forecast as a $9.4-billion deficit for 2026-2027.
USA Pumping at Maximum: US petrochemical production, largely based on domestic natural gas, is at a cost advantage and poised to benefit. US shale operators are running hard and North American producers are the marginal supply story the world is increasingly depending on.
The Consumer Pain: The benefit to producers comes directly at the expense of consumers. Retail gasoline prices rose as much as 6.5 cents per litre overnight in Canada following the February strikes. US gas prices hit $4/gallon by March 31 a 30% surge. Canadian households are absorbing inflation across fuel, food, and transportation simultaneously.
The bottom line for the Berta patch: Alberta producers are printing money right now. The constraint is infrastructure, not price or demand. Watch Trans Mountain utilization and any pipeline expansion announcements close that's where the upside unlocks.
