2026 Multi-Asset Strategies Outlook

Third Quarter

Multi-colored piles of spices.

Key Takeaways

  1. Markets in 2026 may be shaped by inflation pressures, geopolitical risks and evolving market structures that can influence asset behavior in different ways.

  2. Uncertainty around debt levels, retail investor activity and global events highlights the importance of monitoring risks across asset classes.

What Are the Biggest Knowns, Unknowns, and Known Unknowns Facing Markets?

Economics is called the dismal science for many reasons. For one, there are almost an infinite number of variables that could affect economic outcomes, and their values and relationships keep changing.

It’s the opposite of running experiments in a chemistry lab. This seems highly relevant now, given the major unexpected developments affecting today’s stock and bond markets, from technological advances to geopolitics.

This evokes remarks by former Secretary of Defense Donald Rumsfeld, who once reflected on world events and the global economy. He said there are “known knowns,” meaning things we know we know and can prepare for, and “known unknowns,” meaning we know there are things we don’t know.

To investors, known unknowns are risks that haven’t yet been priced into the market. (Rumsfeld also noted that we should acknowledge “unknown unknowns,” which we don't even know we don't know.)

As Rumsfeld pointed out, throughout U.S. and other democratic history, the unknown unknowns have tended to be the most challenging because they can really blindside us. The timing of calamitous, unexpected events like pandemics or terrorist attacks is unpredictable. We can’t see them coming, so they are almost impossible to model or hedge against.

But as investment professionals, we can (and do) ask, “What worries us most right now, beyond traditional market valuation issues? Domestic policy mistakes, geopolitics, energy security, liquidity or something else? And how can we incorporate these risks into portfolio decisions?”

Three particular risks come to mind.

1. China Invades Taiwan (a known risk, definitely not fully priced into markets)

Over 90% of advanced semiconductor chips are made in Taiwan. If China controlled this supply, the economic and market implications could be staggering.

During President Donald Trump’s recent visit to China, President Xi wasted no time in publicly warning Trump about “clashes and even conflicts” with the U.S. over Taiwan. Xi then cited the “Thucydides Trap,” a term coined by the ancient Greek historian Thucydides, who described the Peloponnesian War as the inevitable clash between a rising power and a dominant state. We have no doubt that Xi meant this as a warning about how the U.S. and China manage their rivalry.

This scenario highlights several areas that we believe are worth watching:

  • Whether emerging markets funds have meaningful exposure to Taiwan, particularly in market-cap-weighted indexes that may allocate heavily there.

  • Whether companies rely heavily on semiconductor production in Taiwan, and how supply disruptions could affect related industries, including computers and telecommunications equipment.

  • How sectors such as defense have historically responded to periods of geopolitical tension.

  • How assets often viewed as perceived safe havens, such as gold, have behaved during past episodes of market stress.

2. U.S. Debt/Gross Domestic Product (GDP) Ratio Reaches a Level at Which the Market Starts to Care

We don’t know what that level is, so it’s an unknown, but we know it exists. The U.S. has long enjoyed the privilege of having its debt serve as a perceived safe-haven asset for investors worldwide. But this debt has risen to an unprecedented level (now roughly 120% of GDP). It will keep rising unless U.S. deficits shrink and/or interest rates fall dramatically, neither of which appears likely. Interest costs alone add roughly $1 trillion to the total each year.

U.S. Treasuries are losing their appeal for non-U.S. investors in China, the Middle East and elsewhere. If they sold more than a small portion of their U.S. Treasury assets (China has already reduced its exposure), that could push prices lower and yields higher. The U.S. could print money to buy those bonds, but that would hurt the dollar (increased supply, less demand), pushing inflation higher, as a falling dollar raises the cost of imports.

To address this risk, investors may evaluate a range of approaches, including:

  • Treasury Inflation-Protected Securities (TIPS)

  • Government debt from countries whose currencies may become even more popular as alternatives to the U.S. dollar, such as the yen, Swiss franc and yuan

  • Gold, which some central banks have been buying as an alternative to U.S. Treasuries

  • Hard assets such as real estate

3. Retail Investor Influence Can Reduce the Validity of Market Signals

This risk is hidden in plain sight, as market structure has changed markedly over the past decade. Retail investors now account for 20%-35% of the stock market’s average daily volume, up from 10% a decade ago.

In the options market, closely connected to the stock market, retail trading volume has grown significantly and is considered a major source of market noise. The 'buy-the-dip” mentality among some retail investors may reduce the duration of pullbacks across many stocks. Additionally, increased retail participation could partly explain why the momentum factor has recently dominated, thereby pushing up stock prices.

However, if these investors headed for the exits en masse, we could see significant, sustained downward moves. We believe it’s important to maintain a long-term focus and stay aligned with strategic, long-term asset allocations. Doing so may help reduce this risk by avoiding inadvertent overweights driven by short-term “fear-of-missing-out (FOMO)” momentum.

Don’t Count on Lower Inflation or Interest Rates Anytime Soon

One known known is that the conflict in Iran has made the inflation outlook much worse than it was when Trump chose Kevin Warsh as the new chair of the Federal Reserve. Combined with continued labor market strength, it’s challenging for anyone, including Warsh, to support cutting interest rates.

Inflation is running hot, and the consensus view is that even after the Strait of Hormuz opens, it could take six months or longer for oil supplies to recover and energy prices to move significantly lower.

Not only are gas prices roughly 50% higher than before the war in Iran, but rising shipping costs are also hitting businesses and consumers. Additionally, tight fertilizer supplies (natural gas is a major ingredient in fertilizer) are expected to affect food supplies for months.1

One observer said we should be prepared to pay as much for the hamburger bun as we pay for the beef it holds, as farmers won’t plant wheat if the cost of fertilizer is too high. Weakness in the U.S. dollar, which we have seen over the last year or so, also puts upward pressure on inflation.

All these forces are leading many economists to raise their inflation expectations to 3% or higher in 2026. Our economic outlook continues to favor fairly steady growth, somewhat higher inflation, strong corporate earnings, consumer spending bolstered by the wealth effect of a rising market, and job numbers that remain relatively solid.

We also note less likely possibilities, such as a recession or stagflation on the downside, or an unexpected surge in growth on the upside. While these scenarios aren’t our primary focus, unknown unknowns may lurk, so we remain vigilant.

International investing involves special risks, such as political instability and currency fluctuations. Investing in emerging markets may accentuate these risks.

Investment return and principal value of security investments will fluctuate. The value at the time of redemption may be more or less than the original cost. Past performance is no guarantee of future results.

Historically, small- and/or mid-cap stocks have been more volatile than the stock of larger, more-established companies. Smaller companies may have limited resources, product lines and markets, and their securities may trade less frequently and in more limited volumes than the securities of larger companies.

The letter ratings indicate the credit worthiness of the underlying bonds in the portfolio and generally range from AAA (highest) to D (lowest).

Diversification does not assure a profit nor does it protect against loss of principal.

Rebalancing allows you to keep your asset allocation in line with your goals. It does not guarantee investment returns and does not eliminate risk.

Generally, as interest rates rise, bond prices fall. The opposite is true when interest rates decline.

Past performance is no guarantee of future results. Investment returns will fluctuate and it is possible to lose money.
