Is a 60/40 Portfolio Still the Best Option?

Key Takeaways

• The 60/40 is still a reasonable core, but the falling-rate tailwind and the reliable stock-bond hedge that powered it are gone.
• In 2022 stocks and bonds fell together, and their correlation has been higher in recent years: 0.61 over the past five years versus 0.24 over 20.
• A 10% real-asset sleeve, funded evenly from stocks and bonds, adds diversification a two-asset portfolio cannot.
• A more complete, actively managed framework extends the core rather than replacing it.

The 60/40 portfolio, 60% stocks and 40% bonds, is still a reasonable starting point for a long-term investor with moderate risk tolerance. But the conditions that built its four-decade reputation have shifted, and the case for leaving it untouched is weaker than it was.

At an ETF forum last week, one figure stuck with me: half of fund flows are going into core, building-block products, the 60/40s and target-allocation funds that sit at the center of a portfolio. Investors clearly still want these funds. So, the question isn't whether to abandon the core. It's whether the version most people hold still does what they think it does.

It's worth remembering how unusual the last stretch has been. Outside the COVID crash and 2022, markets have run almost straight up since the financial crisis. A whole generation of investors have built portfolios without ever sitting through a long, grinding decline. That's a comfortable way to invest, right up until it isn't, and it's exactly the kind of environment where diversification stops feeling necessary. That is usually the moment it matters most.

This piece is not an argument that 60/40 is dead. It's a look at the assumptions underneath it: whether they still hold, and what the evidence says about building something more complete.

What Is a 60/40 Portfolio and Why Did It Work for Four Decades?

A 60/40 portfolio puts 60% of your capital in equities, usually broad-market stocks, and 40% in bonds, using the equity sleeve for long-run growth and the bond sleeve for income and a counterweight when stocks fall. Two conditions made that split work for forty years, and understanding them is what makes the rest of this argument coherent.

The first was diversification. For most of the last 40 years, stocks and bonds were only loosely correlated and often moved in different directions. When equities sold off, bonds often rose, cushioning the drawdown and smoothing the ride. That low correlation is the mathematical engine of the whole strategy.

The second was the rate tailwind. The 10-year Treasury yield fell steadily, from roughly 15% in 1981 to under 1% in 2020, and falling rates push bond prices up. For four decades the 40% sleeve earned a return that was built into the environment, not the product of any manager's skill.

Put those together and a classic 60/40 blend, the S&P 500 paired with the Bloomberg US Aggregate, returned about 9% a year over the last 40 years. Its worst peak-to-trough decline was about 18 percentage points shallower than the S&P 500's (Exhibit 2), in exchange for giving up about 2 points of annual return versus stocks alone.

Three exhibits show the record behind those numbers: the blend's calendar-year returns over the last 20 years (Exhibit 1), its drawdowns against the S&P 500 (Exhibit 2), and the 10-year Treasury yield that powered the bond sleeve (Exhibit 3).

Does a 60/40 Portfolio Still Work When Stocks and Bonds Fall Together?

A classic 60/40 portfolio struggles when stocks and bonds fall at the same time, and 2022 showed that this scenario, long treated as a remote tail risk, can arrive fast and hit hard when inflation forces central banks to act.

What happened to the 60/40 in 2022

In 2022, the S&P 500 fell about 18%, and the Bloomberg US Aggregate Bond Index fell about 13% in the same calendar year (Exhibit 4). Both posting meaningful losses in the same calendar year is rare. A classic 60/40 blend lost roughly 16% for the year, its worst calendar-year result since 2008. For investors who had been told the bond sleeve would cushion the equity drop, it was a shock.

The mechanism was straightforward, even if the outcome was not. The Federal Reserve ran one of its fastest hiking cycles in decades. Higher rates compressed equity valuations through the discount-rate math on earnings, and they pushed bond prices down through the basic inverse relationship between yields and prices. The two forces that had spent decades offsetting each other lined up and amplified each other instead.

The correlation shift between stocks and bonds

2022 looks less like a random bad year than a change in the relationship itself. Over the past 20 years, the correlation between the S&P 500 and the Bloomberg US Agg has been a low 0.24, low enough for bonds to offer real diversification. But it climbs as the window shortens, reaching 0.61 over the past five years, a stretch that includes the 2022 rate shock (Exhibit 5). The move from a low-inflation, falling-rate world to a higher-inflation, rate-sensitive one took away the low correlation that 60/40 depends on.

This is not a forecast. It's an observation about what has already happened, and a reminder of what conditions would have to return for the original logic to fully reassert itself.

Is a 60/40 Portfolio Still a Good Investment?

For a long-term investor with moderate risk tolerance and a multi-decade horizon, a 60/40 portfolio is still a reasonable baseline. But the structural conditions that made the bond sleeve a dependable cushion for forty years have changed, and anyone relying on 60/40 unchanged may be carrying risks the track record does not fully capture.

Where 60/40 still holds up

• Simplicity and cost. Built from two index ETFs, a 60/40 portfolio is easy to implement, monitor and rebalance, and it can be run at very low cost. That is a real advantage over more complicated multi-asset structures.
• The long record. One bad year does not erase a forty-year track record of solid returns for the risk taken. 2022 puts that record in context. It does not invalidate it.
• Accessibility. For an investor without access to institutional multi-asset solutions, a disciplined 60/40 beats holding cash or crowding into a single asset class.

Where the assumptions have weakened

• The rate tailwind is over. The forty-year slide in interest rates that lifted bond prices was a feature of the 1980 to 2021 period, and with the 10-year yield back near 5%, it is unlikely to repeat in the same form. Bonds can still pay income and offer some diversification, but the mechanical price gains that padded 60/40 returns are not on the table in a higher-rate world.
• Correlation depends on the regime. The low stock-bond correlation that 60/40 leans on tends to show up in low-inflation periods and weaken or reverse in high-inflation ones. Hold a static 60/40 and you are making an implicit bet on the inflation regime, whether you meant to or not.
• Hidden concentration. A two-asset portfolio can concentrate risk in ways that do not show up on the surface. As VanEck's research notes, much of what passes for globally diversified equity exposure is heavily tilted toward US technology, which means a 60/40 investor may be far less diversified than the label suggests.

This is where a more complete, actively managed approach can help, by addressing those gaps directly rather than hoping the old relationships come back.

What Should You Add to a 60/40 Portfolio for Better Diversification?

One answer the data supports is real assets, and commodities in particular, which have shown near-zero correlation to bonds and just 0.21 correlation to the S&P 500 technology sector over the past 30 years, yet represent less than 1% of total fund assets today.

These are not replacements for 60/40. They are targeted additions that address the specific gaps 2022 exposed. The goal is a more complete framework, not a teardown.

The case for real assets: three decades of chronically under-owned diversification

• Since 1997, US commodity funds have taken in about $188 billion in cumulative net flows. Equity funds pulled in roughly $1.1 trillion. Bond funds pulled in about $5.3 trillion. Commodity allocations have never run much above 2% of fund assets, and today they sit below 1%. (Source: VanEck / Morningstar, June 2026)
• The case is not mainly about commodity returns. It is about correlations. Over 30 years, commodities have been modestly correlated with stocks and bonds, from 0.44 with international stocks down to roughly 0.00 with US bonds, and just 0.21 with US technology stocks (Exhibit 6). (Source: VanEck / Morningstar, June 2026, Bloomberg Commodity Index)
• That last number matters because of where portfolios actually sit today. A passive broad-market equity allocation carries a lot of implicit US technology exposure. Commodities offer a return profile that is genuinely different from that concentration, not a watered-down version of it.
• On valuation: against US stocks, commodities have recently traded near their cheapest levels since the 1970s. In the past, comparable extremes have often been followed by commodity outperformance, though that is a historical pattern, not a forecast. (Source: VanEck / Bloomberg, June 2026)
• The test case is 2022. When stocks and bonds fell together, commodities gained about 16%, and a 55/35/10 mix lost about 13% versus about 16% for a plain 60/40 (Exhibit 7). Real assets are not a universal hedge, though. In 2008, commodities fell about 36%, and 55/35/10 lost slightly more than 60/40, about 24% versus 22% (Exhibit 7).

Gold: a distinct role from commodities

Gold does something different from broad commodities, and the difference matters for how you build a portfolio. It is less economically sensitive and responds mainly to real interest rates, the dollar, and geopolitical stress. Think of it as a debasement hedge and a tail-risk instrument, not an inflation play in the way commodity producers are. Investors can own gold as physical bullion, which tends to be less volatile and less correlated with equities, or through gold equities, which tend to behave more like stocks. Each has a specific role. (Cross-link to VanEck's dedicated gold research.)

Structural growth themes beyond broad equity

The 60% equity sleeve in a classic 60/40 is usually a passive broad-market allocation, and that leaves return on the table while concentrating your exposure in whatever the index weights most heavily at the moment. Targeted exposure to structural themes, think AI infrastructure, semiconductors, electrification and natural resources, can add differentiated return potential inside the equity sleeve without simply piling on more market beta. The point is that the equity sleeve itself can be made more purposeful.

What allocation makes sense?

So how much is enough to matter without taking over the portfolio?

Here is where a small, deliberate addition earns its place. Think of digital assets as hot sauce. You do not build the meal around it, but the right amount changes the whole plate. Carve a sliver of that 10% sleeve into digital assets and the risk-adjusted numbers improve. Splitting the sleeve 8% real assets and 2% digital assets, rather than 10% real assets alone, improved returns for the risk taken in a hypothetical back test of the last ten years, with volatility little changed (Exhibit 8).

There is a trade-off worth naming. The all-real-assets 55/35/10 version was the better crisis hedge. It had the shallowest max drawdown of the three, about 3 percentage points shallower than a plain 60/40. The gains are modest, though: moving from 60/40 to 55/35/10 improved returns for the risk taken only slightly (Exhibit 8). So, this is a choice between optimizing for overall risk-adjusted efficiency and optimizing for crisis-specific ballast, not a strict improvement either way. Treat the digital-asset slice as an optional refinement on top of the core recommendation, not a replacement for it. (Source: Morningstar Direct, October 1, 2016, through September 30, 2026.

How Often Should a Multi-Asset Portfolio Be Rebalanced?

A multi-asset portfolio should be rebalanced on a regular schedule or when allocations drift past set bands, but the more important decision is whether you are rebalancing back to a fixed target at all or letting a manager adjust that target as conditions change.

The drift problem

A strong equity year can quietly turn a 60/40 portfolio into a 72/28 or 75/25, raising your risk without any decision on your part. Letting the mix drift is itself an active allocation decision. It just happens passively, and without intent.

There is also a macro layer. Mechanical rebalancing pulls a portfolio back to its target, but it never asks whether the target is still the right one for the current environment. An active approach is to manage exposure around long-term structural tilts, trimming into rallies and adding during dislocations rather than snapping back to a fixed number. That is the difference between a static 60/40 and a dynamically managed multi-asset framework. VanEck's 2026 Outlook describes this approach as "built to be adaptive by rebalancing, managing exposure after rallies and adding opportunistically during periods of dislocation."

What Does a More Complete Portfolio Framework Look Like in Practice?

A more complete portfolio framework does not discard the 60/40 structure. It extends it, adding asset classes that address the specific vulnerabilities 2022 exposed: inflation sensitivity in the defensive sleeve, genuine diversification from assets with low correlation to both stocks and bonds, and the active discipline to hold that allocation through volatility.

In principle, it looks like the 55/35/10 idea. Keep the core. Fund a real-asset sleeve evenly from both stocks and bonds. Make the equity portion more purposeful rather than purely passive. Manage the whole thing actively instead of letting it drift. And, optionally, carve a small slice toward digital assets for added efficiency.

Conclusion

The 60/40 portfolio is not broken, and it is not dead. It is a sound core built for a particular set of conditions, some of which no longer hold. The rate tailwind that padded bond returns is gone, and the low stock-bond correlation that made the bond sleeve a reliable cushion can no longer be taken for granted. None of that argues for abandoning the core. It argues for completing it: adding real assets for genuine diversification, making the equity sleeve more intentional, and managing the allocation actively instead of letting it drift. Investors clearly still want a strong core to build around. The opportunity is to build a better one.
