Canada's factory boom is panic buying in disguise

CANADA'S manufacturing sector has posted its strongest streak of growth in years. The S&P Global purchasing managers' index, a monthly survey of factory bosses that reads above 50 when the sector is expanding, has remained above that threshold for six straight months. In June it edged up to 53.0, a reading that would once have been cause for quiet celebration. It is not now.

The trouble is that this expansion looks less like an economy finding its footing and more like one bracing for impact. Growth is being propped up by two forces that do not signal healthy demand: panic stockpiling ahead of fresh American tariffs, and rush ordering prompted by the Middle East war's disruption of global shipping. Peel away these distortions and the underlying picture is rather less cheerful.

The war between Israel and Iran, which began in March, closed the Strait of Hormuz, a sea channel through which roughly a fifth of the world's oil and gas passes. The resulting spike in energy prices sent a shiver through supply chains. Canadian factory bosses report that suppliers' delivery times have lengthened to the greatest degree since the end of 2022, according to S&P Global. Firms have been hoarding inputs and their clients have been stockpiling finished goods in case prices rise further or products become scarce. The stocks-of-purchases component of the PMI hit its highest level since last August.

This is not the sort of growth that lastingly strengthens an economy. It borrows demand from the future and stores it in a warehouse. When the fear subsides - or when warehouses are full - the spending stops.

A second distortion has been even more specific to Canada. Since early 2025, America has imposed sectoral tariffs on Canadian steel, aluminium, lumber and automobiles. Canadian firms responded by front-loading inventories, buying goods while tariff costs were still manageable. That inventory accumulation was, according to the chief economist of Global Affairs Canada, the main contributor to Canada's economic growth last year. It was a clever short-run response to an unwise long-run constraint. But front-loaded orders are a one-time event, not a growth engine.

The data from inside the PMI confirm the fragility. Input prices rose to 67.2 in June, their highest level since the summer of 2022, driven by high oil prices, disrupted freight routes and existing American tariffs. Businesses managed to pass some of these costs on - the output-price measure stood at its highest since July 2022, too - but business confidence slipped to a three-month low. Employment is rising, to its strongest level since the autumn of 2024, but only because firms are hiring to cope with workloads created by artificial urgency. When the urgency fades, those jobs may not.

To be sure, some of the recovery is real. The new-domestic-orders component has been rising, suggesting that Canadian consumers and non-manufacturing businesses are spending a bit more freely. The Bank of Canada's July monetary-policy report judged that GDP growth had resumed in the second quarter, estimated at 2½%, and that sources of expansion appeared to be broadening. Consumer spending, in particular, has shown resilience.

Yet the Bank of Canada is navigating a policy trap. It held its policy rate at 2.25% in July, its sixth straight hold, and projected that inflation would ease gradually back to its 2% target by early 2027. Headline inflation breached the bank's 3% upper limit in May, mainly because of gasoline prices tied to the Hormuz closure. The bank's case for holding rates rests on the assumption that these cost pressures are transitory and that the economy has sufficient slack - the unemployment rate was 6.5% in June - to absorb the shock without reaccelerating underlying inflation.

That assumption is about to be tested harder than anyone expects. On July 20th, the American president invoked Section 338 of the Tariff Act of 1930 - a statute unused for at least 70 years - to impose additional 50% tariffs on a wide range of Canadian goods, from dairy to electronics to furniture. The tariffs take effect on August 19th and cover nearly $20bn in annual Canadian exports to the United States. They apply even to goods that qualify under the USMCA free-trade agreement.

The consequence will be immediate and disquieting. American importers facing a 50% duty on Canadian goods will either stop buying them, push the cost onto consumers or scramble to source substitutes. Canadian exporters, meanwhile, have been one of the brighter spots in the recovery narrative: the Bank of Canada judged that export growth had resumed and was expected to continue strengthening. That story now looks as though it has been preemptively written.

The broader lesson is structural. Canada's economy is the world's most trade-dependent among large advanced economies, and roughly three-quarters of its exports flow south. When its largest trading partner treats it less like a partner and more like an adversary to be leveraged, conventional macroeconomic tools lose much of their force. Interest rates cannot offset a 50% tariff wall. Currency depreciation - the Canadian dollar has weakened against the dollar in part because of the tariff overhang - helps exporters but makes imported inflation worse.

What should Ottawa do? Retaliation, the natural first instinct, would punish Canadian consumers with higher prices on American goods without changing American behaviour. The wiser approach is to negotiate, even from a position of weakness. Canada should pair diplomatic pressure on American consumers, farmers and manufacturers who rely on Canadian supply chains with targeted domestic support for the hardest-hit sectors. It should also accelerate efforts to diversify trade, however incrementally, towards the Asia-Pacific and Europe. The economics of proximity will always favour the United States, but the politics of dependence have a cost.

The Bank of Canada, meanwhile, should resist the temptation to raise rates in response to tariff-driven inflation spikes. Those spikes are supply shocks, not demand pulls. Tightening in response would suppress domestic consumption at the very moment the economy needs it most. If oil prices retreat and shipping normalises, the inflation problem will largely resolve itself.

Canada's factory PMI may have risen to a four-year high. But the factories are running hot not because demand is strong, but because everyone is afraid. That is not a recovery. It is a postponement.
