Strait of Hormuz Crisis Pushes Oil Past US$100, Reshaping Canada's Inflation and Budget Picture

The shutdown of the Strait of Hormuz by Iran has reshaped global oil markets and is feeding back into the Canadian economy in ways that are at once a windfall for federal and Alberta budgets and a fresh threat to the country's hard-fought progress on inflation. With Brent crude trading near US$108 a barrel and West Texas Intermediate touching the high US$90s, Canadian energy producers are seeing their best price environment in years, even as drivers, businesses and policymakers grapple with the inflationary fallout.

What is happening

Shipping traffic through the Strait of Hormuz has been largely blocked by Iran since late February, when the United States and Israel launched coordinated air strikes against Iranian nuclear and military targets and assassinated supreme leader Ali Khamenei. In retaliation, Iran launched missile and drone attacks on Israel, US bases and US-allied Gulf states. The Iranian Revolutionary Guard Corps issued warnings forbidding passage through the strait, has boarded and attacked merchant ships, and has reportedly laid sea mines in the waterway.

Since 13 April, the United States has imposed a blockade on Iranian ports, leading to a so-called dual blockade of the strait. Before the war, the strait carried about 25 per cent of the world's seaborne oil trade and 20 per cent of the world's liquefied natural gas. The disruption has rippled across global markets, with oil prices climbing roughly 50 per cent above where they sat at the start of the conflict.

Most recently, Iran has signalled it would reopen the strait if the United States lifts its blockade and ends the war, while setting aside nuclear negotiations for later. US Secretary of State Marco Rubio called the proposal unacceptable, leaving the diplomatic standoff in place and the strait essentially closed for now.

The Canadian budget windfall

The federal government's spring economic update, tabled this week by Finance Minister François-Philippe Champagne, was buoyed by the higher oil revenue environment. Officials credited surging energy prices as one factor behind the deficit's improvement to $66.9 billion for 2025-26, down from the $78.4 billion forecast in November.

The Alberta provincial budget is benefiting even more directly. Royalty revenue scales with oil prices, and the provincial treasury is on track for one of its strongest fiscal years since the late 2010s. Premier Danielle Smith's government has used the cushion to fund tax measures and other priorities while running its information campaign for the October referendum.

Saskatchewan and Newfoundland and Labrador are also seeing royalty improvements, although the latter province's offshore production cycles mean the gains are more modest. British Columbia, Quebec and Ontario, by contrast, are experiencing the inflationary side of the equation more acutely than the revenue benefit.

The inflation problem

The flip side of higher oil prices is the inflationary impact on consumer prices. Canada's headline inflation rate eased to 1.8 per cent in February before the war's effects began to bite, but the Bank of Canada and private-sector forecasters now expect headline inflation to touch 3 per cent this spring before settling back as the price shock works through the system.

For Canadian households, the immediate impact is at the gas pump and on home heating costs. Diesel fuel, which feeds into trucking and freight costs, also feels the impact, with downstream effects on the prices of consumer goods that travel by road. The federal government's temporary suspension of the fuel excise tax, announced in the spring update, is designed in part to ease the pump-price impact for drivers.

The Bank of Canada has held its policy rate at 2.25 per cent at recent decisions, signalling a wait-and-see posture as the inflation picture evolves. Bank governors have indicated that the next rate move is more likely to be a hike than a cut if inflation pressures persist, although the central bank has stressed it will be guided by underlying data rather than a single price shock.

The economic balance

The Canadian economy contracted in the fourth quarter of 2025 and lost roughly 100,000 jobs in early 2026, with the unemployment rate climbing to 6.7 per cent in February. Youth unemployment, in particular, has been elevated, with the rate among 15-to-24-year-olds edging back above 14 per cent in February.

The combination of weak labour market conditions, rebounding inflation and trade conflict with the United States has created a difficult backdrop for monetary policy. The Bank of Canada is balancing the risk of inflation re-igniting against the risk of stalling a still-fragile recovery, and the strait crisis is making that balance harder to strike.

For Canadian businesses, the higher oil price environment offers some upside in the energy sector but adds costs across other industries. Manufacturers, transport companies and agriculture all face higher input costs, and the pass-through to consumers depends on competitive dynamics in each market.

Diplomatic stakes

Canada has not had a significant role in the diplomatic efforts around the strait, with the United States and Gulf states leading the negotiating tracks. Foreign Affairs Minister Anita Anand has been engaged with allies on the broader peace and stability question, and has reiterated Canada's support for de-escalation and the protection of civilian shipping.

Canadian companies operating in the region, including those in the energy and shipping sectors, have adjusted their operations to account for the closure. Insurance premiums for ships transiting the area have soared, and many operators have rerouted cargo around the Cape of Good Hope despite the higher cost.

The federal government has not announced any specific Canadian military commitment to the maritime security operations in the area. Canadian naval assets have been deployed in support of allied operations elsewhere, including in the Pacific as part of the Balikatan exercises with the United States, the Philippines and Japan.

The energy export picture

The crisis has highlighted the strategic value of Canada's energy export capacity. The Trans Mountain Expansion, which came online in 2024, has provided an additional outlet for western Canadian heavy crude to access Pacific Rim markets, and demand for that capacity has been strong throughout the war.

Canadian liquefied natural gas exports, including from the LNG Canada project at Kitimat that began commercial operations in 2025, have also been positioned as a complement to global supply during a period of constrained Middle East shipments. Industry executives have argued the crisis underscores the case for further LNG capacity on the West Coast and East Coast.

For oil sands producers, the elevated price environment translates into stronger cash flow and the potential for accelerated capital spending. Carney's new Canada Strong Fund, announced this week, will operate in part as a vehicle for co-investment in energy and critical mineral projects, and the windfall environment may make those investments more achievable.

Reaction from opposition parties

Conservative Leader Pierre Poilievre has used the price shock to argue for accelerating the development of Canadian energy infrastructure, including pipelines and LNG terminals. NDP Leader Don Davies has emphasised relief measures for households facing higher costs and has called for stronger consumer protections in essential goods markets.

The Bloc Québécois has linked the price environment to the urgency of climate-related industrial transformation, arguing that Quebec's hydroelectric and clean technology assets are positioned to benefit if the country accelerates the transition away from fossil fuels.

What it means for Canadians

For Canadians, the immediate experience of the crisis is at the gas pump and in monthly utility bills. The government's fuel excise tax suspension provides modest relief, but the broader inflation environment remains uncomfortable for households still working through the after-effects of the post-pandemic price shock.

Renters and prospective homebuyers may find their plans further disrupted if elevated inflation prevents the Bank of Canada from delivering rate cuts that had been anticipated for later in 2026. Conversely, retirees and savers may benefit from the prospect of higher returns on fixed-income investments.

Energy sector workers, particularly in Alberta and Saskatchewan, are likely to see the most direct economic benefit from the elevated price environment. Other Canadians will see the costs more directly than the gains.

What's next

The diplomatic standoff over the strait shows no sign of immediate resolution. With Iran offering reopening in exchange for an end to the blockade and the war, and the United States rejecting that proposal in its current form, the conflict's economic effects are likely to persist into the summer.

For Canadian policymakers, the focus will be on managing the dual pressures of higher revenue and higher prices, while preserving the broader economic recovery. The Bank of Canada's next interest-rate decision will be closely watched, as will the federal government's handling of CUSMA negotiations against this elevated price environment. The strait crisis has reminded Canadians that the country's economic health remains tightly linked to global geopolitics, even when the immediate flashpoint is half a world away.

Strategic petroleum reserves and supply security

The crisis has also reignited the long-standing debate about whether Canada should maintain its own strategic petroleum reserve. Most major oil-importing economies hold reserves that can be released into domestic markets during supply disruptions. Canada, as a net oil exporter, has historically not seen the need for such a reserve, although certain regions of the country, particularly Eastern Canada, depend on imports and could be exposed to disruptions.

Industry analysts and some policy advocates have argued the war makes the case for a more proactive Canadian approach to energy security, including coordinated planning with the United States and other allies. Federal officials have not signalled any imminent change in posture, but the issue is on the agenda of broader energy security reviews currently under way in Ottawa.

Eastern Canadian refining

Eastern Canadian refineries, which historically depended on imported oil for portions of their throughput, have adapted over the past decade to use a higher share of domestically sourced supply via Line 9 and other pipeline reversals. The crisis has further reduced reliance on imports from disrupted regions, but logistics across the eastern Canadian energy system remain more constrained than in the west.

The Irving refinery in Saint John, the largest in Canada, processes a mix of domestic and imported crude depending on market conditions and pricing. Its operations during the current crisis have been monitored closely as one indicator of how Atlantic Canadian fuel supply is responding to the disruption.
