Treasury Yields Exceed 5% as Global Bond Selloff Accelerates Before Fed Decision
The 10-year benchmark climbed above 5%, reaching 5.04% intraday on Tuesday, its highest level since July 2007, as investors unloaded government debt across developed markets. The move wasn't isolated to U.S. Treasuries. German bunds climbed past 2.7%, and the Canadian 10-year Government bond yield rose to 3.8%, marking a two-year high, a level that translates directly into higher fixed mortgage rates when homeowners renew next year.
This is the return of the term premium. For a decade after the financial crisis, investors accepted near-zero compensation for the risk of holding long-term government debt because central banks were reliable buyers and inflation was dormant. That equilibrium broke in 2022, and what's happening now is the market re-pricing that risk in real time.
The immediate trigger is tomorrow's U.S. Consumer Price Index release. Markets are hyper-reactive to inflation prints because core services inflation, the category that includes wages, rents, and medical care, has remained elevated when central banks need it below 2.5% to comfortably hit their targets. A single upside surprise in tomorrow's number would likely push the 10-year through 5% outright because it gives bond traders permission to demand more yield for holding duration, even if the underlying inflation trend remains unchanged.
Why Canadian rates are following U.S. yields up
The correlation between U.S. and Canadian long-term yields runs above 0.8 in normal conditions. When the U.S. 10-year climbs, the Canadian 10-year typically trails by 50 to 100 basis points, depending on domestic economic slack. The Bank of Canada controls the overnight rate, the short end of the curve. Global capital flows and inflation expectations determine the 10-year yield, not decisions made by the Bank's policy committee.
This creates a floor. Even if the Bank of Canada wanted to ease aggressively to support housing or consumption, it cannot force long-term Canadian bond yields meaningfully below U.S. Treasuries without triggering a currency collapse. If Canadian 10-year yields fall too far relative to their U.S. counterparts, capital flows out, the Loonie depreciates, and imported inflation rises, forcing the Bank to stay hawkish precisely when it wanted flexibility.
For Canadians who took out 5-year fixed mortgages in 2021 at 2.8%, a 5% 10-year U.S. Treasury yield environment means their renewal rate in 2026 will likely land somewhere between 4.5% and 5.2%, depending on the lender's margin over the 5-year Government of Canada bond. That cohort represents roughly 40% of outstanding mortgages by volume. The payment increase isn't marginal. On a $600,000 mortgage, the monthly cost jumps from $2,740 to $3,480, an extra $740 every month.
What rising yields break first
The equity market pressure is already visible in rate-sensitive sectors. Canadian utilities, telecoms, and REITs have underperformed the broader index by 8 percentage points since August as the 10-year yield climbed. These are the "widow and orphan" holdings, stable dividend payers that retirees and pension funds use as bond proxies. When the risk-free rate approaches 5%, a stock yielding 4.5% with equity volatility stops looking like income and starts looking like unnecessary risk.
The traditional 60/40 portfolio, 60% equities, 40% bonds, was built on the assumption that bonds rally when stocks fall, providing ballast. Inflation-driven yield spikes break that assumption. Both assets sell off together, which is what happened in 2022 and what is beginning to happen again now. Institutional portfolios that assumed bonds were safety have discovered they were holding duration risk in a rising-rate world.
If tomorrow's CPI number comes in hot, 5% on the 10-year becomes the new floor, not the ceiling.
