Long-term government bond yields have risen across many major markets to levels not seen in decades (1). Investors are increasingly demanding compensation for long term risk, inflation uncertainty, elevated borrowing needs, and reduced central bank support. Together, these forces reflect a significant shift from the low-yield, quantitative easing-driven environment that prevailed for much of the past decade.
This is about more than just the bond market. Long-term bond yields play a central role in the global financial system, influencing borrowing costs, capital allocation decisions, and asset valuations. Their impact extends from corporate financing and real estate prices to equity discount rates. However, the rise in yields has been concentrated at the longer end of the curve and, on its own, does not necessarily indicate a meaningful deterioration in economic fundamentals (2).
Investors also appear skeptical of central bank measures intended to stabilize bond markets, as bond yields continue to rise even after these measures are announced. While initiatives such as bond buyback programs may improve market liquidity, they do little to address the underlying challenge of growing debt issuance.
Hyperscalers such as Meta, Oracle, and Amazon are issuing unprecedented volumes of long-term debt (3) to finance data centre expansion and artificial intelligence investments. This is increasing competition for investor capital at the long end of the yield curve, alongside elevated government borrowing needs to fund fiscal programs.
The Canadian story is not materially different. While Canada has generally maintained stronger fiscal metrics than many G7 peers, long-term Government of Canada bond yields (4) have moved higher alongside global markets as investors reassess inflation risk, debt supply, and term premiums.
What this means for portfolios
For Canadian balanced portfolios, higher long-term yields create both challenges and opportunities. While bond prices may remain sensitive to further yield increases, the higher yield environment has improved the long-term return potential of fixed income and reinforces the value of diversification across asset classes, yield curve segments and credit sectors.
For Canada Life Investment Management managed portfolios, we’re keeping an eye on three key considerations:
- Diversification within fixed income. While long term government bonds are typically held for income generation, liquidity, and downside protection, other fixed income sectors including short-term bonds, investment-grade corporates, global real return bonds, mortgages, and private credit may perform differently in an environment where long-term yields remain elevated.
- Diversification beyond traditional fixed income. When inflation remains persistent and interest rates stay higher for longer, real assets can play an important diversification role. Real estate, infrastructure, and private credit derive returns from different economic drivers than long-term government bonds. Periods of elevated yields and sticky inflation are precisely when these assets can earn their place in a balanced portfolio.
- Rebalancing discipline. Large moves in bond markets can lead to meaningful portfolio drift from targets. Rebalancing helps restore the intended risk profile by trimming positions that have outperformed and adding to areas that may offer more attractive valuations following a sell-off. In volatile market environments, a disciplined rebalancing process can be an important source of long-term return enhancement and risk management.
When could this turn?
We believe there are two potential catalysts that could help relieve pressure on long-term U.S. bond yields:
- A more aggressive Federal Reserve response to inflation. Additional monetary tightening could push short-term interest rates higher while helping to contain inflation expectations, potentially lowering long-term yields and resulting in a flatter yield curve.
- A shift in U.S. Treasury funding strategy. A move away from long-term bond issuance and toward short-term Treasury bill issuance, similar to the approach adopted in 2023, could reduce the supply of long-dated bonds and alleviate some upward pressure on long-term yields.
While Canadian yields are driven by domestic economic and market factors, developments in the U.S. can still influence their direction given the close integration of global fixed income markets.
A similar dynamic is unfolding across other developed markets, including Japan, the United Kingdom, and Canada, where policymakers and investors continue to assess the interplay between inflation, government borrowing needs, and the rise in long-term interest rates (5).
Finding opportunity in higher yields
For much of the last two decades, investors benefited from a combination of declining inflation, falling interest rates, and central banks that actively purchased government debt through quantitative easing. Today's backdrop looks different. Governments are issuing more debt, central banks are no longer major buyers, and investors are demanding higher compensation for lending money over long periods.
While rising yields have created short-term price pressure for long-term bonds, they have also improved future expected returns across fixed income. Investors can now earn substantially higher yields than they could for much of the past decade, which may ultimately benefit long-term portfolio outcomes.
The recent rise in long-term yields should not necessarily be viewed as a sign of economic weakness. Rather, it reflects a market that is reassessing the value of long-term capital in a world of evolving fiscal priorities and ongoing economic growth. Our focus remains on maintaining diversified portfolios and taking advantage of the opportunities created by changing environments.
