Last week, following the US imposition of tariffs and Prime Minister Mark Carney's retaliatory measures, Canadian bonds rallied in a flight to quality as investors sought the safety of government bonds in an uncertain trade environment. While both shorter- and longer-term bonds rallied, investors are increasingly looking at bond yields to ensure their investment yields continue to outpace inflationary pressure. US bond markets responded to the Federal Reserve’s (Fed’s) preferred inflation data release, and investors searched for policy insights and guidance from Fed Chair Kevin Warsh’s speech at the annual Jackson Hole Symposium. 

In Canada, swap markets continued to price in a Bank of Canada (BoC) rate hold ahead of this Wednesday's decision, as investors weighed the potential inflationary and growth-dampening impact of new tariffs against energy price pressures stemming from the Middle East conflict. Amidst this uncertainty, Canadian government bonds rallied, most pronounced at the shorter-end of the curve. The two-year treasury yield moved 3 basis points lower to close the week at 3%.

Second-quarter headline Canadian gross domestic product (GDP), a measure of economic activity, came in at 3.3%, a slight miss to expectations of 3.4% but the fastest quarterly expansion since 2023 according to Bloomberg. While the quarterly growth was stronger, bond markets had a limited reaction to the posting, as investors remained focused on recent US-Canada trade developments moving into the third-quarter.  

In the US, the Fed's preferred inflation gauge—the core personal consumption expenditures (PCE) price index—largely met expectations by rising 3.3% year-over-year, though it remained above the Fed’s target. At the Jackson Hole Symposium, Fed Chair Warsh emphasized that the 2% price-stability objective is a firm, fixed target, noting that the Fed requires confidence that underlying inflation is trending toward this goal. Following the speech, shorter- to medium-term Treasuries sold off and yields rose, as markets re-priced the probability of a 25-basis-point Fed rate hike in September, increasing from 39% to 58% to close the week.   

Many investors are observing headlines of decade-highs in long-term global bond yields, conventionally defined across the 10- to 30-year maturity spectrum. While these elevated yields present an opportunity for fixed income investors, it is equally important to understand the risks and diverse drivers behind these moves—ranging from geopolitical tensions and oil price volatility to broader inflation expectations and concerns regarding fiscal sustainability. Compounding these pressures are significant supply dynamics driven by hyperscalers, whose substantial AI infrastructure spending is boosting new bond issuance and testing the market's capacity to absorb new debt.

In response to these uncertainties and supply dynamics, investors have demanded higher interest rates for holding long-term debt. This is evidenced by 30-year UK gilts reaching yields not seen since the 1990s, US Treasuries breaching the key 5% psychological threshold to hit two-decade highs, and Canadian yields returning to 2010 levels. While recent government intervention (such as the doubling of the US Treasury’s buyback program) aims to contain these rising rates and bolster treasury liquidity, the persistence of elevated yields continues to place significant pressure on both government and consumer borrowing costs, while also providing an opportunity for investors to take advantage of higher yields.

By understanding the evolving drivers behind long-term yield movements, investors can better evaluate the opportunities present in fixed income. While these conditions offer a chance to lock in higher available yields, bond investing still comes with inherent risks. However, for those with a long-term horizon who hold fixed-income securities to maturity, such market fluctuations are simply par for the investment course.
