Crude oil has fallen 33 percent since mid-May as the Strait of Hormuz reopens and Washington's new 60-day licence lets Iranian barrels back onto the water. Most of that decline will not show up at a Canadian pump the way the headline number suggests, because the Canadian dollar has refused to rally on the same news that crashed the price of oil.
Why a Barrel Priced in U.S. Dollars Needs a Loonie to Buy It
WTI settled at $108.66 on May 18. By late-morning trading on June 23, the August contract was changing hands near $73.23, a five-week slide of roughly 33 percent. The mechanism is straightforward: the U.S. and Iran signed a framework in Switzerland, Washington granted Tehran a 60-day licence to sell oil internationally, and shipping traffic through Hormuz has resumed enough that Kuwait and the United Arab Emirates are routing cargo through it again. The war premium that built into crude through the spring is unwinding.
WTI's daily settlement price has tracked a near-uninterrupted descent from the high $100s to the low $70s, with the steepest single-day drops arriving once Hormuz traffic resumed and the Iranian licence was signed in the window's final days.

Bank of Canada Governor Tiff Macklem has been here before. Asked about May's inflation print, he described the 3.2 percent annual rate, the first reading above the Bank's 1 to 3 percent target band in 29 months, as an energy story rather than a broad one. A crude collapse of this size is exactly the kind of move that framework expects to resolve itself by the July 15 decision.
It has not worked that way for the currency. The Canadian dollar closed at 71.7 cents US on June 10. It traded at 70.44 cents US in Tuesday's late-morning session, the lowest close of the year, with the slide accelerating specifically through June 17, when Fed Chair Kevin Warsh's FOMC held rates while nine of nineteen members projected at least one more 2026 increase, and through Monday's Switzerland announcement that was supposed to be unambiguously good news for Canadian inflation.
The Currency Tax the Morning Desks Could Not See Yet
Run the same two weeks through both currencies and the gap appears. WTI fell 18.7 percent in U.S. dollar terms between June 10 and June 23. Converted into loonies at each day's exchange rate, the same barrel fell 17.2 percent, from roughly $125.55 to $103.96 Canadian. The difference is not large on any single day, but it compounds: every barrel Canada imports buys less relief per dollar of U.S. price decline than it did two weeks ago, because the currency it is priced through has been falling for reasons that have nothing to do with oil.
The Canadian dollar's daily closes since June 10 show a steady slide that picked up pace exactly when the Fed's hawkish hold and the Switzerland announcement landed, rather than easing on either piece of news.

The mechanism is the Fed, not the barrel. The U.S. dollar index broke above 100 for the first time in more than a year this week, and December hike futures now price better than 89 percent odds of another move. That is a U.S. monetary story, and it is overpowering the Hormuz-driven relief that should be flowing into the loonie from the oil side of the ledger. For the July 15 decision, the practical read is that the disinflation Macklem is counting on from energy will arrive smaller, in Canadian dollar terms, than the U.S. dollar oil chart implies.
The Capital Relief Sitting Underneath Today's Sell-Off
The S&P/TSX Composite fell through 35,000 on Tuesday, down roughly 152 points in late-morning trading as technology and mining names led the retreat. The TSX 60, weighted toward the largest banks and energy producers, held up better than the broader index on the same day, and the reason predates today's selling by 24 hours.
Canada's banking regulator lowered capital requirements for the country's largest lenders this week, the first such easing in three years, freeing balance sheet capacity for additional lending. Royal Bank gained roughly 1 percent and BMO gained roughly 1.2 percent on Monday's announcement alone. That is a structural, regulator-driven tailwind for bank earnings capacity, and it has nothing to do with the rate fears now hitting technology and mining shares.
The two forces are running in opposite directions on the same stocks. OSFI is expanding what the banks can lend at the same moment the Fed's hawkish posture is raising the cost of capital broadly and the BoC is still six weeks from confirming whether May's inflation surprise was the one-off energy story Macklem described. An advisor reading today's TSX headline as a referendum on bank balance sheets is reading the wrong instrument. The capital relief is durable. The rate uncertainty is not. Tomorrow's conversation with a client holding bank-heavy Canadian equity exposure should separate the two explicitly, because the composite number blends a regulatory story for the banks with a Fed story for everything else.
