In January 2022, a 60-year-old American with a conventional retirement portfolio of 60% stocks and 40% bonds might have felt reasonably secure. The bond portion was there to provide stability, income, and a cushion when stocks fell. That was the basic idea behind decades of conventional portfolio thinking.

By the end of the year, the picture looked very different. The S&P 500 had returned about −18%, while the Bloomberg U.S. Aggregate Bond Index had fallen about 13%. A simple 60/40 mix using those benchmarks therefore lost roughly 16%.

For someone approaching retirement, this was genuinely alarming. Stocks having a bad year was nothing unusual. What made 2022 different was that the broad investment-grade bond market also suffered one of its worst years, sharply weakening the diversification benefit many investors had come to expect.

This does not mean bonds no longer have a role in portfolios. It means the conventional wisdom about why they belong, how much to hold, and what to expect from them needs to be understood more carefully.

Why Bonds Exist in Portfolios at All

Bonds can serve four distinct functions in a portfolio, and they don’t always all work at the same time:

Income generation. Many bonds provide scheduled interest payments, making them a useful source of portfolio income. For retirees drawing from a portfolio, or anyone who wants investments to generate cash flow, that regular income can be an important part of the bond allocation.

Capital preservation. Short-duration, high-quality bonds generally have lower price volatility than stocks, while U.S. Treasuries also carry very low default risk. They can therefore play a useful role when preserving capital matters more than maximizing long-term growth. But bond prices can still fall, especially when interest rates rise or credit conditions deteriorate.

Volatility reduction. High-quality bonds tend to be less volatile than stocks. Adding them to a stock-heavy portfolio can reduce overall price swings and make drawdowns less severe. That can matter not only mathematically, but behaviorally: a portfolio that is easier to live with may also be easier to hold through difficult markets.

Diversification. This is the function that came under the most pressure in 2022, and the one that needs the most nuance. During many recessionary or risk-off periods, investors have moved toward high-quality government bonds, often helping Treasury prices rise while stocks fall. That relationship provided valuable diversification during episodes such as 2001, 2008, and the early stages of the 2020 pandemic. In 2022, it behaved very differently.

The Correlation That Isn’t Always Negative

The negative stock-bond correlation, the tendency for bonds to rise when stocks fall, is not a law of nature. It is a relationship that changes with the economic environment.

For much of the 1970s and 1980s, stock and bond returns were positively correlated. Inflation was a persistent concern during much of this period, and shocks that pushed inflation and interest rates higher could put pressure on both bonds and stocks.

The relationship changed around the late 1990s. Stock-bond correlation turned negative and remained predominantly negative for more than two decades. During an era of relatively low and stable inflation, recession and deflation became more prominent threats. When growth weakened, the Fed could cut interest rates, bond prices could rise, and those gains could help offset stock-market losses.

Then 2022 arrived. Inflation surged to 40-year highs and the Fed raised interest rates aggressively. Bonds were hit by rising yields, while stocks also came under pressure as interest rates rose and financial conditions tightened. Both fell sharply at the same time.

The broader lesson is that stock-bond correlation depends on the type of economic shock investors are facing. Inflation is an important part of that relationship. When recession or deflation is the dominant concern, high-quality bonds can provide particularly valuable diversification. When an inflation shock pushes interest rates sharply higher, stocks and bonds can fall together.

The 60/40 Portfolio: Where It Came From and What It Really Means

The 60% stocks / 40% bonds allocation did not emerge from a single study or breakthrough insight. It evolved over time as a practical way to combine the growth potential of stocks with the stability and income of bonds.

Part of its intellectual foundation can be traced to Harry Markowitz’s Modern Portfolio Theory, introduced in 1952. Markowitz showed that combining assets that do not move perfectly together can improve a portfolio’s risk-return trade-off. Bonds therefore had value not only because they were generally less volatile than stocks, but because their returns could behave differently from equities.

The practical case for 60/40 was reinforced by decades of strong results. From the early 1980s through 2020, balanced stock-bond portfolios benefited from both equity-market growth and a powerful long-term decline in interest rates.

That decline mattered. The 10-year Treasury yield climbed above 15% in the early 1980s and, decades later, fell below 1% in 2020. As yields trended lower over that long period, existing bonds often benefited from price gains in addition to the income they paid.

That does not mean every year was favorable for bonds, or that falling rates alone explain the success of 60/40. Stocks provided most of the long-term growth, while diversification and rebalancing also mattered. But investors during those decades experienced an unusually favorable backdrop for the bond side of the portfolio.

The Age-Based Rules: Useful Starting Points, Not Commandments

One of the best-known bond-allocation rules is remarkably simple: hold roughly your age in bonds.

Under that rule, a 30-year-old might hold 30% bonds, while a 60-year-old might hold 60%.

The logic is intuitive. Younger investors generally have more time to recover from stock-market losses and can often tolerate greater equity exposure. As retirement and portfolio withdrawals approach, preserving capital and reducing large swings may become more important.

Vanguard founder Jack Bogle, one of the most influential investors in history, used age in bonds as a rough guideline. Target-date retirement funds follow a similar broad principle: they generally begin with heavier stock exposure and gradually shift toward bonds and other fixed-income assets as the target retirement date approaches.

Other age-based variations have also emerged, such as 110 minus age or 120 minus age for the stock allocation. A 60-year-old following the 110-minus-age rule, for example, would hold 50% stocks rather than the 40% implied by the original age-in-bonds rule.

However, age alone cannot determine an appropriate bond allocation. Two investors of the same age can have very different circumstances.

Income sources. Reliable income from pensions, Social Security, or other sources can reduce how much cash flow must come from the investment portfolio.

Risk tolerance. Two investors with similar finances can react very differently to the same market decline. A portfolio that is theoretically efficient but too volatile for someone to hold through difficult markets may not work well in practice.

Spending needs. An investor making regular withdrawals has different liquidity and stability needs from someone who is still accumulating assets and does not expect to draw from the portfolio for many years.

Time horizon. Age is only a rough proxy for how long the portfolio may need to support the investor. The relevant horizon can differ substantially even among people of the same age.

Three Investor Profiles: Different Ages, Different Approaches

Rather than abstract rules, let’s see what sensible bond allocations might actually look like at different life stages.

The 28-Year-Old Early Investor

At 28, with more than three decades before retirement, the primary portfolio goal is often long-term growth. A long time horizon gives the investor more opportunity to recover from stock-market declines and can support a relatively high equity allocation.

But the portfolio still has to be one the investor can actually hold through a severe downturn. Suppose stocks fall 40% while high-quality bonds remain roughly unchanged. An all-stock portfolio would fall 40%, while a portfolio with 10–15% in bonds would fall roughly 34–36%. Although the difference is not enough to eliminate the pain, it can provide a somewhat smoother ride and leave relatively stable assets available for rebalancing.

Illustrative starting allocation at 28: 85–90% equities, 10–15% bonds (primarily short-to-intermediate duration, high quality).

The 45-Year-Old Mid-Career Investor

At 45, there may still be roughly two decades before retirement, leaving meaningful time for equity growth. But the portfolio may also be much larger than it was earlier in life, making the dollar consequences of a major decline more significant.

Suppose an investor has a $1 million portfolio invested 70% in stocks and 30% in high-quality bonds. If stocks fall 40% while the bond portion is unchanged, the portfolio would fall about 28%, leaving roughly $720,000. An all-stock portfolio facing the same stock-market decline would fall to $600,000. A bond allocation can therefore reduce the impact of a severe equity decline while still leaving substantial exposure to long-term growth.

As retirement gets closer, sequence-of-returns risk also becomes increasingly important. A major decline shortly before or after withdrawals begin can be harder to recover from because withdrawals may reduce the capital available to participate in a subsequent rebound.

Illustrative allocation at 45: 70% equities, 30% bonds (mix of short- and intermediate-duration securities, diversified across Treasuries and investment-grade corporates).

The 65-Year-Old New Retiree

At retirement, the portfolio has a different job. It may need to preserve capital, generate income, fund regular withdrawals, manage sequence risk, and still maintain enough growth to support a retirement that could last decades.

Several adjustments are worth considering for retirement-stage investors:

The bucket strategy — dividing the portfolio into short-term cash and bonds (2–3 years of spending needs), medium-term bonds (years 4–10), and long-term equities (10+ years). This helps keep spending needs for the next several years from depending on stock market performance, reducing the forced-seller dynamic that makes crashes genuinely harmful.

TIPS allocation. Treasury Inflation-Protected Securities can help protect part of the portfolio from unexpected inflation because their principal adjusts with changes in the Consumer Price Index.

Illustrative allocation at 65: 45–50% equities, 35–45% bonds (tilted toward short-to-intermediate duration, incorporating some TIPS), 10–15% cash.

What 2022 Actually Taught Us

The 2022 experience was painful, but it contained a genuinely useful lesson rather than simply being an argument to abandon bonds.

The bonds hit hardest were long-duration bonds, including long-term Treasuries and long-duration corporate bonds. TLT, the iShares 20+ Year Treasury Bond ETF, lost more than 31% in 2022. Short-duration Treasuries held up far better. The iShares 1–3 Year Treasury Bond ETF, for example, lost only about 3.9%.

That distinction matters for portfolio construction. Two investors can both say they hold 40% in bonds while taking very different amounts of interest-rate risk. A portfolio dominated by long-duration bonds can react much more sharply to rising rates than one concentrated in shorter-duration securities.

The lesson from 2022 was therefore not that bonds were broken. It was that duration risk is real, and the composition of the bond allocation matters alongside the percentage assigned to bonds.

What Higher Yields Changed

After years of unusually low yields, the rate reset that began in 2022 changed the starting point for bond investors.

Higher yields mean bonds can generate more income from the outset. They also provide a larger income cushion against some price declines than investors had when yields were close to zero.

That does not make bonds risk-free or erase the lessons of 2022. Longer-duration bonds can still fall sharply when yields rise, corporate bonds still carry credit risk, and stock-bond diversification can weaken during inflationary shocks.

What has changed is that investors no longer have to rely as heavily on falling interest rates to make the bond allocation useful. Income itself can once again do more of the work.

For portfolio construction, that shifts the question away from simply whether to own bonds toward what role the bonds need to play, how much interest-rate risk to take, and what level of credit risk fits that role.
