Why 60/40 worked for so long
For most of the period from 1980 to 2020, equities and government bonds were negatively correlated — when stocks fell, bonds rose as investors sought safety, and vice versa. This negative correlation meant a 60/40 portfolio produced smoother returns than a pure equity portfolio, with significantly lower drawdowns. A portfolio that avoids catastrophic losses allows the investor to stay invested through cycles, and staying invested is the primary driver of long-run wealth accumulation.
The 2022 failure — and why it happened
In 2022, the 60/40 portfolio suffered its worst year since the 1930s, losing roughly 16%. Equities fell as growth expectations collapsed; bonds fell simultaneously because interest rates rose sharply (bond prices move inversely to rates). The problem: the entire post-1980 era of bonds-cushioning-equities relied on structurally declining interest rates. When central banks had to aggressively raise rates to fight inflation, that correlation flipped. Both asset classes sold off together.
Is it still relevant?
The 60/40 is not dead, but it needs updating. The theoretical underpinning — diversification across assets with different return profiles — remains sound. The specific assumption that government bonds will always offset equity falls is the part that needs revision. With yields back to historically normal levels (3–5%), bonds now provide a genuine income buffer that was absent in the near-zero-rate era. They may not be the perfect hedge they once were, but they're not worthless either. The 2022 losses have largely been recovered.
Modern alternatives and additions
Some investors supplement 60/40 with: gold or commodities (which held value in 2022); property (real estate investment trusts); international diversification; or inflation-linked bonds. The key insight is that no static allocation is optimal forever — the correlation structure of the market changes. But the core principle of mixing growth assets with defensive assets remains the right starting point for any balanced investor.
"The 60/40 portfolio is like a reliable car — not the fastest, not the flashiest, but it gets most people to their destination if they don't abandon it mid-journey."
What this means for you
For most individual investors with a 10+ year horizon, a 60/40 or similar balanced allocation remains a sensible default — particularly inside a pension or ISA where you want simplicity and low cost. Adjust the equity/bond split based on your time horizon: younger investors typically skew toward 80/20 or even 100% equity; those approaching retirement might move toward 40/60 or 30/70 to reduce sequencing risk. The 2022 year was painful but within the long-run range of expected outcomes for a balanced portfolio.
