Houthi missiles and drones struck three Saudi Aramco facilities on September 8, hitting the 400,000-barrel-per-day Jazan refinery along with sites at Abha and Najran, wounding 73 people and forcing Saudi Arabia to halt operations at several southern energy facilities. WTI crude closed that day at $92.72. The Canadian portfolio consequence is not the price level. It is what kind of risk this attack confirms is now in play.
From a Chokepoint to a Supply Source: Why the Distinction Matters for Canada
For six months, the dominant Middle East oil risk has been transit through the Strait of Hormuz, the passage that historically carried roughly 20 million barrels a day, about a fifth of global supply. Transit risk has a workaround: reroute tankers, draw down strategic reserves, redirect cargoes. It is disruptive, but it is not irreversible.
A strike on Saudi production infrastructure is a different category of risk. The Jazan refinery cannot be rerouted around. It has now been targeted repeatedly since July. That shift, from a chokepoint that can be worked around to production capacity that cannot, is the specific mechanism that keeps a floor under Brent and WTI even in the weeks when ceasefire talk pushes prices down. For Canadian portfolios, it is the reason TSX energy names and the Canadian dollar carry a structurally elevated bid as long as the war continues, not just a bid on days when a specific attack makes headlines.
Six Months of Round-Trips, Not One Spike
WTI crude has moved between the high $60s and the low $110s four separate times since the war began in early March: a surge to $111.54 in early April, a collapse to $94.43 on the first ceasefire announcement, a slide to $69.63 by late June as that ceasefire briefly held, and a climb back into the $90s through the summer as it broke down again.
The chart below tracks that full path against the events that drove it. September 8’s Houthi strikes are the latest inflection, not a new pattern.
WTI has crossed $100 twice and fallen back below $70 twice since the war began in March, with each reversal tied to a ceasefire announcement or its collapse rather than a change in underlying supply capacity.
Base Case Versus Tail Risk
The base case is that the price stays elevated in a wide band, roughly $80 to $100, as the war continues without a resolution and without a strike large enough to take meaningful capacity permanently offline. In that base case, Canadian energy remains a genuine relative outperformer domestically, and the Canadian dollar keeps a modest lift from stronger terms of trade, even as the broader TSX absorbs damage from unrelated stories, as it did this week from a tech and industrials-led decline.
The tail risk is a strike that hits a major export terminal rather than a refinery serving domestic and regional demand. Saudi Arabia’s largest export infrastructure, at Ras Tanura, has not been targeted in this round. A strike there would test the $126 intraday level reached in late April, and at that level the IEA’s own demand-destruction math starts to dominate the story: global growth risk broad enough that it would stop being a Canadian energy tailwind and start being a Canadian growth problem, energy sector included.
