3 Trends Pressuring 60/40 Portfolios Over the Next Decade

The oft-heard advice to “stay the course” may be inappropriate for the investing environment that's coming.

Many investment discussions focus on the outlook for the next quarter or year. Although the focus on the “here and now” is understandable, most investors should measure their time horizon in years or decades. The distinction between short- and long-term is particularly important today, with near-term “noise” obscuring material changes in long-term economic trends.

Given what is likely to be a different long-term investment environment, balanced portfolios comprising 60% stocks and 40% bonds may provide returns that fall short of the lofty levels reached over the past decade.

Stock and bond returns have benefited from globalization, the “peace dividend,” and abundant energy supply. Each of these “tailwinds” for investment returns is likely turning into a “headwind” at a time when the U.S., China and much of Europe will be struggling with an aging population:

1. Globalization, Regionalization and Fragmentation

Declining globalization and regionalization of supply chains could lead to a fragmentation of economic markets. The loss of U.S. manufacturing jobs, rising income inequality, the COVID-19 pandemic and U.S.-China tensions are among the factors contributing to the backlash against globalization.

One lasting consequence of the pandemic will be a focus on supply chain resiliency. Although the “just-in-time” approach to inventories might have been the optimal financial strategy during placid times, the pandemic exposed the need to consider more of a “just-in-case” approach for key elements within the supply chain.

Changes in approach to managing supply chains and stalling of other aspects of globalization are likely to raise costs and create pressure on corporate profit margins. In addition, fragmentation within the global economy is likely to reduce the total addressable market for many companies with global aspirations. But while global brands may find themselves with a shrinking opportunity set, national or regional champions may benefit from a more “localized” market.

2. The Diminishing ‘Peace Dividend’

Russia’s invasion of Ukraine marks the end of a long period in which capital market valuations and government balance sheets were boosted by relative peace between superpowers. Government spending on defense will likely rise in much of the world as a global arms race looks inevitable. Increased government spending to address energy and food insecurity also will create more of a tax on economic growth while sustaining inflationary pressures.

A less stable world with higher risk of superpower conflict may cause pressure for equity valuations, particularly when geopolitical tensions are elevated.

3. Climate Transition: Expensive and Disruptive

Decarbonization will be challenging and create some uncomfortable trade-offs. Consumer wallets will feel the impact of persistently high energy prices and increased taxes, while periodic service interruptions may be the price of reducing the world’s reliance on fossil fuels.

Shortcomings in government policy are likely to be exposed during a transition in which there will be unpleasant trade-offs between present and future stakeholders. Steps by policymakers to slash red tape will be controversial, while speeding financing and providing tax incentives to jumpstart the rebuilding of supply chains will be expensive.

If the war in Ukraine and sanctions against Russia continue, the U.S. will face some difficult choices between promoting domestic energy production or acquiring more oil from repressive regimes.

The next decade for markets is likely to feature lower returns, higher inflation and greater volatility. Although inflation will likely decline from current peak levels, the “new normal” is likely to be above 3%.

With inflation perhaps the greatest threat to returns and monetary policy moving from a loosening to a tightening bias, bonds may not be as consistent a hedge against falling stock market prices. In addition, with bonds still at tepid yields relative to inflation, income-focused investors may need to supplement traditional bond holdings in the search for yield.

Consequently, the oft-heard advice to “stay the course” may be inappropriate for the environment of the coming decade. Long-term investors should think about making some “course adjustments” to add investments that provide incremental diversification, inflation protection and/or incremental income:

The 60/40 portfolio is not obsolete; traditional stocks and bonds still have a vital portfolio role. However, given changes in the long-term outlook, investors may need to be more creative to achieve the returns required to meet financial goals and manage market volatility. Diversification, inflation protection and incremental income may be harder to find, but will be available to those willing to do the necessary work.
