On Wednesday, the US Treasury tried something explicit: expand its long bond buyback program to hold down borrowing costs directly. By Thursday, that intervention had already reversed in the bond market. Canadian advisors watching to see who won the argument this week, the Treasury or the bond market, got their answer in the gold and oil moves that followed it, and the answer bears directly on the Bank of Canada's September 2 decision.
A Debt Auction Alternative That Did Not Hold
The 30 year US Treasury yield closed at 5.25% on August 14 and climbed to 5.31% on August 17, touching an intraday 19 year high near 5.33% on August 18 as the US national debt crossed $40 trillion for the first time. Treasury Secretary Scott Bessent then said the department's bond buyback operation could grow beyond $4 billion per issue, and the 30 year yield fell to 5.19% the day the announcement landed.
The relief did not last. By Thursday the yield had rebounded to 5.23%, and by Friday's close it sat at 5.27%, essentially back to where the week began. A tool built to cap long term borrowing costs held for one session.
Gold Kept the Gain Yields Gave Back
Gold's daily settlement price climbed from $4,076.40 on July 21 to $4,661.60 by Friday, a one month advance of roughly 14.4% that accelerated sharply in the week of the buyback announcement. The metal jumped 2.82% the day the buyback was unveiled and kept climbing even after the 30 year yield fully reversed course.

That divergence is the tell. A one week yield reversal did not resolve what gold is pricing. The metal is treating the buyback as evidence of a structural borrowing problem rather than a policy fix, and it has not walked that view back even as the bond market did.
Two Rallies, Two Stories That Do Not Cancel
WTI closed at $86.30 on Friday and Brent at $93.40, both up on the week for a second straight weekly gain, but for a reason unrelated to gold's move. The US is preparing sweeping new economic sanctions against Iran, and hopes for a near term reopening of the Strait of Hormuz weakened through the week.
A fiscal credibility signal and a supply shock signal pushed commodities higher at the same time for unrelated reasons. That means the inflation read heading into September carries two separate risks stacked on top of each other, not one.
The TSX's Flat Week Hid a Split Between Miners and Banks
The S&P/TSX Composite closed at 36,620.23 on Friday, up 0.70% on the day but down roughly 0.30% for the week from last Friday's 36,730.27 close. Materials rose 2.7% Friday alone, a five month high, as gold miners tracked bullion higher. Heavyweight financials also climbed ahead of bank earnings next week, but the broader index absorbed strain from the same Treasury market stress that pushed Government of Canada yields higher in sympathy.
The Canada 10 year yield closed at 3.76% Friday, its highest since May 2024, tracking the US move rather than reflecting a change in the Bank of Canada's own outlook.
CAD Strengthened for a Reason That Has Nothing to Do With Canada
USD/CAD fell to 1.3764, the Canadian dollar's third consecutive weekly gain, but the driver was mostly American. US retail sales fell in July by the most in over a year, while Canada's own economy is estimated to have expanded at an annualized 3.4% in the second quarter, above the Bank of Canada's 2.5% forecast, and July employment rose by 75,100 jobs against a 15,000 estimate. The yield differential narrowed because US data disappointed, not because Canadian data forced a hawkish repricing.

What Changes Before September 2
The coming week carries the calendar risk this week's price action was reacting to in advance. The July PCE price index and Nvidia earnings land Wednesday, the Federal Reserve's Jackson Hole symposium opens Thursday, and Fed Chair Kevin Warsh delivers his first Jackson Hole address as chair on Friday, August 28, three trading days before the Bank of Canada's September 2 rate decision.
That sequencing gives the Bank of Canada a piece of information this week's markets do not yet have priced: Warsh's own framing of where Fed policy goes from here. Whether he validates the bond market's version of this week (yields settle near multi year highs and the buyback was a one time gesture) or the gold market's version (the debt story is structural and this was the first of several buybacks) is the split worth watching between now and September 2, not the next daily headline on oil.
