How Much in Bonds Should I Hold? A Guide by Age

Bond allocation is one of the most debated questions in personal finance. The answer has shifted significantly in 2026 compared to the 2010s, when near-zero interest rates made bonds unattractive relative to equities. With rates now normalised, bonds offer genuine yield again — changing the calculus at every life stage.

Why Bond Allocation Matters

Bonds serve two functions in a portfolio: they provide income (through regular interest payments, or “coupon”) and they dampen volatility (because bond prices tend to move differently to stock prices in most market environments). The amount of bonds you hold is the single biggest determinant of how much your portfolio swings during market turbulence.

A portfolio with 80% stocks and 20% bonds might fall 35% in a severe bear market. The same portfolio with 50% stocks and 50% bonds might fall 20%. The difference is not just numerical — it is the difference between an investor who holds through the drawdown and one who sells in panic and locks in the loss permanently.

The Classic Rules of Thumb — and Why They Need Updating

Two widely cited rules dominate the conversation on bond allocation by age:

• The “100 minus your age” rule: Hold your age as a percentage in bonds. A 40-year-old holds 40% bonds, 60% stocks. Simple, but originated in an era of higher expected bond returns and is widely considered too conservative for today’s longer lifespans.
• The “110 or 120 minus your age” rule: A more aggressive modern variant. A 40-year-old holds 30% bonds (110–40) or 20% bonds (120–40). More appropriate for someone with a long time horizon and other income sources in retirement.

Neither rule accounts for your specific situation: your other income sources, your mortgage and debt position, your pension or social security entitlements, or your psychological risk tolerance. They are starting points, not prescriptions.

Bond Allocation by Age: A 2026 Framework

How 2026 Interest Rates Change the Calculation

From roughly 2010 to 2022, holding bonds carried an opportunity cost that made high allocations difficult to justify. 10-year government bond yields sat near 1–2% in most developed markets — barely above inflation. Holding 40% in bonds meant holding 40% of your portfolio in assets that might deliver 1% annual returns after inflation. Small wonder that many advisers quietly pushed investors toward higher equity allocations than their age might traditionally have suggested.

By 2026, that calculation has reversed. US 10-year Treasuries yield around 4–4.5%. Investment-grade corporate bonds yield 5–6%. Short-duration government bonds yield 4%+ with minimal rate risk. A 40% bond allocation now generates meaningful real income — changing the risk/reward analysis at every age cohort.

Concretely: a 55-year-old holding 50% in bonds in 2026 is not sacrificing growth for safety the way they would have been in 2018. They are holding an asset yielding 4–5% annually while protecting against equity drawdowns. That is a qualitatively different trade-off.

Types of Bonds: Not All Are Equal in Risk

The bond allocation percentage matters — but so does the type of bond. Bond risk varies enormously by duration and credit quality:

• Short-duration government bonds (1–3 years): Lowest rate risk, lowest credit risk. Yield approximately 4–4.5% in 2026. The safest bond category and the right choice for investors within 3 years of needing their money.
• Intermediate government bonds (3–7 years): Modest rate sensitivity, strong credit quality. The core holding for most moderate-risk investors. Yield approximately 4–4.5%.
• Long-duration bonds (10–30 years): High rate sensitivity — a 1% rate rise causes 10–20% price decline. Only appropriate for investors comfortable with bond volatility and confident about rate direction.
• Investment-grade corporate bonds: Higher yield than government bonds (5–6%), with additional credit risk. Appropriate as a complement to government bonds, not a replacement.
• High-yield (junk) bonds: Yield 7–9%, but carry significant credit risk and correlate more with equities during market stress. Not a true diversifier for equity risk.

Adjusting Your Bond Allocation in Practice

If you determine your bond allocation is too low, increasing it gradually is usually preferable to making a sudden large shift. Redirect new contributions to bond funds over 6–12 months rather than selling equity holdings all at once. This avoids potentially crystallising capital gains and reduces the risk of shifting at an inopportune market moment.

If your bond allocation is too high — common among investors who moved to safety during the 2022 selloff and did not reinvest — the same gradual approach applies in reverse. Systematically move from bonds to equities over several months rather than all at once.

Bonds vs. Cash: An Often-Overlooked Distinction

In the 2010s, bonds and cash were nearly equivalent in yield, so the distinction barely mattered. In 2026, with short-term rates at 4–5%, holding cash in a savings account or money market fund can actually compete with short-duration bonds on yield while carrying zero duration or credit risk. For the portion of your conservative allocation you may need within 1–2 years, high-yield savings accounts or money market funds may be more appropriate than bonds in 2026’s rate environment.

For money you will not need for 3+ years, bonds remain the right vehicle — they provide portfolio diversification that cash does not, and lock in current yields for longer periods rather than being subject to rate fluctuations on cash savings rates.
