Tariffs, Treasuries, and Jackson Hole: What’s Moving Markets

In this week’s edition of Steady Investor, we break down the latest developments shaping the economic and market outlook, including:

Will the Escalating U.S.-Canada Trade Spat Hurt Markets? The U.S.-Canada trade dispute escalated again after trade talks broke down and the U.S. imposed 50% tariffs on a targeted group of Canadian goods. Canada responded with plans for dollar-for-dollar retaliation, which prompted the U.S. to threaten to raise tariffs on Canadian autos and auto parts to 50% starting January 1, 2027.As a general economic principle, we are no fans of tariffs and trade wars. Tariffs are almost always a negative because they raise costs for businesses and consumers, and in our view, it ultimately hurts the imposer as much as the target. In the context of this current escalation, however, investors should weigh the scale and timing. The new U.S. tariffs apply to about $20 billion to $28 billion of Canadian goods, depending on the estimate, which represents a very small share of total U.S.-Canada trade. Recent reporting pegs the affected goods at roughly 5% of Canadian exports to the U.S., while most trade between the two countries remains governed by USMCA rules. Canada’s retaliatory tariffs are also scheduled to start September 8, leaving room for further negotiations in the coming weeks.We are not implying that the impact here is so negligible that it should be outright ignored. But remember, markets have had a lot of experience with tariff volatility over the past year, and unless the dispute broadens meaningfully, this still looks more like another trade-policy flare-up than a major threat to the expansion.1

What Today’s Market Signals Mean for Investors

Bond Woes Go Global – The recent rise in U.S. Treasury yields has drawn plenty of attention, and it’s the subject of Mitch Zacks’ latest Mitch on the Markets column. But the upward pressure on yields is not limited to the U.S.Global debt has surpassed $350 trillion, according to the Institute of International Finance, equal to about 305% of global GDP. Governments in advanced economies alone are expected to borrow roughly $18 trillion this year, according to the OECD. That growing supply of debt is arriving at a time when investors are also weighing inflation risk, central-bank uncertainty, and competition from other asset classes.The pressure has been especially visible overseas. France’s 10-year yield has risen about half a percentage point since the end of June, while Italy’s has climbed nearly as much. By comparison, the U.S. 10-year Treasury yield is up about 0.2 percentage point over the same stretch. Japan’s bond market has also been under pressure as inflation becomes more entrenched after decades of deflation, while U.K. yields remain sensitive to fiscal concerns and shifting demand from traditional buyers like pension funds.3

The common thread is that higher debt levels make markets more sensitive to changes in inflation expectations, politics, and central-bank credibility. When investors demand more compensation to lend, borrowing costs rise for governments—which can translate to higher borrowing costs for businesses and households.

What Investors Should Watch for as the Fed Heads to Jackson Hole – Fed Chair Kevin Warsh heads to Jackson Hole with a basic question still unanswered: is inflation being kept above target by temporary shocks, or by an economy running too hot? If tariffs, the Iran war, and higher energy costs are the main drivers of above-target inflation, the Fed may be able to wait for those pressures to fade. But if strong demand, AI-driven investment, and healthy credit growth are allowing price increases to stick, then the argument for higher rates becomes stronger. The Fed is clearly divided. Three officials voted to raise rates at the July meeting, the most dissents in a decade, while others remain more patient. Softer inflation data over the past two months has reduced pressure for an immediate move in September, but inflation has still been above the Fed’s 2% target for more than five years. That puts Warsh’s leadership style—and his press conference in Jackson Hole—in focus. Warsh has argued the Fed should communicate less and avoid giving markets too much forward guidance, but the flip side to this approach is that markets are increasingly in the dark. Markets do not need a guaranteed rate path, but they do need to understand what data the Fed is watching and how policy might respond. That’s what makes Warsh’s speech so meaningful—it can give markets a clearer framework for interpreting the Fed’s next move.5

Navigating Markets During Geopolitical Uncertainty – Ongoing geopolitical and economic uncertainty continues to shape investor sentiment and contribute to periods of market volatility.

Understanding the potential impact of these developments may help investors make more informed decisions and maintain a long-term perspective.
