What do higher government bond yields mean for investors?

• Higher bond yields are not necessarily a warning sign for investors. They largely reflect stronger growth, persistent inflation, higher demand for capital and a return to more normal market conditions after a period of unusually low yields.
• Today's higher yields have improved the long-term return potential of bonds. This gives investors a much better starting point than they had a decade ago, meaning expected returns are also correspondingly more attractive.
• While we remain cautious on government bonds, they continue to play an important role in portfolios and funds as they can potentially provide important diversification during economic downturns.

In many countries, government bond yields have risen significantly in 2026, prompting questions from investors. For some, higher yields evoke concerns about government debt burdens, fiscal sustainability and the potential for negative returns from bond investments.

However, while rising debt levels are undoubtedly part of the story, we believe the recent move in bond yields has multiple drivers: including resilient economic growth, persistent inflation and elevated demand for capital across the global economy. We do not view current yield levels as a cause for significant concern. Rather, they are returning to more normal levels after a prolonged period of being unusually low. 

While headlines often focus on debt concerns, robust nominal growth conditions are as important, if not more important, in explaining today’s yield levels.

A longstanding rule of thumb in bond markets is that long-term government bond yields may, over time, gravitate toward nominal GDP growth, which combines real economic growth and inflation. If the US economy is expected to grow at around 2% per year in real terms while inflation averages approximately 3%, nominal GDP growth would be about 5%. In that environment, a 10-year Treasury yield near 5% could be considered broadly reasonable, although actual yields are also influenced by monetary policy expectations, term premiums, and global demand for government bonds.

The value of investments, and the income from them, can fall as well as rise and you may not get back what you put in. Past performance should not be taken as a guide to future performance. You should continue to hold cash for your short-term needs. This article should not be taken as advice.

Inflation has remained above central bank targets for several years and has shown signs of renewed upward pressure during 2026. Combined with resilient economic growth and ongoing fiscal deficits, this helps explain why bond yields have risen to higher levels. While a modest economic slowdown could lead to some easing in yields, we believe the broad range of current yields is likely closer to the new normal, rather than the exception.

In addition, central banks retain tools to support financial stability, including quantitative easing (QE). These could be deployed if higher bond yields become disruptive for financial markets and governments. However, our base case for now is that such tools won’t be called upon.

One factor that has attracted significant attention is the level of government debt around the world. Countries with higher debt burdens, such as Japan or Italy, have generally experienced larger increases in bond yields this year. Investors can demand greater compensation to lend to governments when debt levels are high, particularly if fiscal deficits remain elevated.

At today's levels, debt servicing costs are becoming a much larger proportion of government budgets than they were during the era of ultra-low rates that followed the global financial crisis (GFC). Given the political challenges associated with austerity measures, we believe that policymakers are likely to rely more heavily on economic growth and inflation to reduce debt burdens, rather than making fiscal spending cuts.

However, debt alone does not explain recent market moves. Yields have increased across a wide range of countries, including some with relatively modest debt levels. This suggests broader forces are also at work. 

Many of the current themes shaping today's economy require enormous amounts of investment. Artificial intelligence (AI), defence, and the energy transition are all competing for capital expenditure. Importantly, this spending is not confined to governments. Companies are also borrowing heavily to fund investment programmes, particularly within the technology sector and the build-out of AI-related infrastructure.

As demand for capital increases, governments and corporations increasingly compete for investor funds. In simple terms, when more borrowers seek financing simultaneously, investors tend to require higher yields – and this competition for capital will have contributed to this year’s rising bond yields. 

It is worth remembering that today's bond yields are not historically unusual.

The period after the GFC was characterised by exceptionally low inflation, weak productivity growth and extensive central bank asset purchases. These forces helped suppress bond yields to historically rare levels.

Looking over a much longer period, current yields appear far less extraordinary. UK government bond yields have averaged around 6% since the 1930s. Viewed through that lens, current yields represent a return to more typical conditions rather than a dramatic departure from them. 

For several years we have recommended an underweight allocation to government bonds, and that remains our position today.

Our preference has been to rely on a broader range of diversifiers, including assets such as gold and liquid alternatives where appropriate, to help improve portfolio resilience. We continue to believe investors need multiple sources of diversification. 

We still see value in bonds though. We generally own assets for two reasons: their return potential and their diversification benefits. Government bonds continue to offer both.

Firstly, starting yields are one of the strongest indicators of future bond returns. Today's yields are significantly higher than those available a decade ago, meaning expected returns are correspondingly more attractive. Higher yields also provide investors with a much larger cushion against future rate increases. Based on current yield levels, yields would need to rise substantially and remain elevated for some time before investors would experience meaningful losses over a multi-year horizon.

Secondly, bonds remain one of the most effective hedges against recession risk. Although the diversification benefits of government bonds have been less consistent in recent years, we would still expect them to perform well during a sizable growth shock. In such an environment, investors typically seek safe-haven assets, and central banks often respond by cutting interest rates, both of which tend to support government bond prices. Historical analysis suggests that even in periods of elevated public debt, bonds have retained their ability to provide protection during economic downturns.

In conclusion, while we remain cautious on government bonds relative to other opportunities, higher yields have also improved bonds’ long-term investment case. For us, they therefore remain an important component of a well-diversified portfolio.
