Stocks 60 Bonds 40 — Still a Thing?
The 60/40 portfolio was the standard asset allocation for decades. Then 2022 happened, and people called it dead. Let's walk through how 60/40 emerged and where it stands today.
The most enduring asset allocation in investing has been 60% stocks, 40% bonds. US pension funds, Korean retirement default options, the starting templates at global asset managers — nearly all of it built off this ratio. Then 2022 hit, 60/40 took a heavy loss, and the obituaries showed up. Let's walk through how 60/40 emerged and where it stands today.
How 60/40 emerged
The 60/40 structure wasn't built by any single person — it settled into place naturally through US academic thinking in the 1950s and 1960s.
In 1952, Harry Markowitz published Modern Portfolio Theory. The core idea: there's an asset combination that delivers the best return for a given level of risk. Mixing two assets with different risks can produce a better return-to-risk ratio than holding either alone.
This framework first hit the field at large US pension funds. Through the 1960s and 1970s, the 60% stocks 40% bonds ratio took hold as the standard. The mix was judged a strong balance between growth and risk, and it became the default at US pensions.
Two assumptions sit underneath this.
First, stocks return more than bonds over the long run, with more volatility. Putting some of your assets into stocks speeds up long-term growth.
Second, stocks and bonds generally move opposite each other. In good economies, stocks rise and bonds soften a bit. In bad economies, stocks fall and bonds tend to rise. Whichever side takes losses, the other partially covers.
These two assumptions working together is what made 60/40 the strong return-to-risk structure that pensions adopted.
The decades when 60/40 ran hot
From 1980 to 2020, the 60/40 portfolio posted very strong returns. The US version averaged roughly 9% annually. A 100 million won deposit in 1980 grew to over 3 billion won by 2020.
A specific macro environment drove that run.
US rates moved from about 18% to 20% in the early 1980s down to 0% to 1% by 2020 — one long downtrend. Falling rates means rising bond prices, so US long bonds steadily appreciated for 40 years. US stocks ran from about 130 on the S&P 500 in 1980 to about 3,700 in 2020 — roughly a 28x increase. Both sides pushing up together produced exceptional 60/40 results.
The 60/40 also held up well in crises during that stretch. When stocks fell in the 2000 dot-com bust, bonds rose. When stocks fell in the 2008 financial crisis, US long Treasuries rose sharply. Across your total portfolio, the losses were partially offset.
The 2022 shock
The 60/40 picture broke in 2022.
The Fed hiked rates 11 times in a single year. The fastest pace in 40 years. That shock hit both assets at once.
First, rising rates pushed up the discount rate applied to future earnings, and growth stocks took the heaviest blow. The S&P 500 fell about 18% on the year, the Nasdaq about 33%.
Second, the same rate-hike shock landed directly on bond prices. US long Treasury ETFs fell about 30% on the year. Korean 30-year government bond ETFs took similar hits.
Stocks and bonds dropped in the same direction, and the 60/40 portfolio posted its worst single-year loss since the 1930s. The US 60/40 ran about -17% on the year. 100 million won shrank to roughly 83 million won in one year.
The cause was straightforward. The same macro shock — inflation and rate hikes — hit both assets at once. Diversification works when two assets face different shocks. When the same shock hits both, diversification's effect shrinks.
So is 60/40 done?
Plenty of analysts argued post-2022 that "60/40 is over." That conclusion deserves a second look.
First, the 2022 joint drawdown is a very rare event. Across 47 years from 1976 to 2022, stocks and bonds both fell in the same year only 4 times. In the other 43 years, when one fell, the other softened the blow. 2022 came from an exceptional macro setup — rapid rate hikes combined with an inflation shock.
Second, 60/40 has been recovering since 2023. US 60/40 returned about 17% in 2023 and showed similar momentum into 2024. A meaningful portion of the 2022 loss has been clawed back. Looking at the long-run data, 60/40 has shown this recovery pattern after big crises before.
Third, 60/40 was never built as short-term protection — it was built as a long-term growth-plus-risk-balance structure. The possibility that any single year could go badly was baked in from the start. If you're holding the assets across a 10 to 30 year horizon, the impact of one rough year fades over time.
That said, whether 60/40 will run as hot as it used to is an open question. The 1980 to 2020 backdrop of falling rates won't repeat in the same way. So some managers are building on top of 60/40 rather than leaving it as is.
How 60/40 is being extended
The most discussed direction for extending 60/40 is broadening asset-class diversification.
First, adding inflation-resilient assets. Gold, commodities, inflation-linked bonds. During an inflation shock like 2022, when stocks and bonds fell together, those assets moved differently.
Second, broadening regionally. Moving from a US-stock-plus-US-bond 60/40 to a global-stock-plus-global-bond version. Not tied to one market.
Third, mixing in alternatives. REITs, commodity ETFs, and similar. When you add assets that move differently from the standard stock-bond pair, the diversification widens.
That said, scrapping 60/40 entirely isn't the consensus call. The core 60/40 structure (stocks for growth, bonds for protection) still has its place — building outward from it is the more natural direction.
Wrapping up in one line
60/40 settled into place in the 1950s and 1960s and ran very strongly from 1980 to 2020. 2022's inflation-plus-rate-hike shock produced its worst single year since the 1930s. That said, the joint drawdown was a 4-in-47 exception. Rather than 60/40 being over, the more common direction now is layering global, inflation-resilient, and alternative assets on top. If you hold 60/40, check what you might add around it.
