Bond Allocation for Retirees

Retirees face a risk that workers do not: sequence-of-returns risk. A 2008-like crash in the first years of retirement can derail a portfolio. Bonds don't solve this completely, but they do reduce it—if chosen carefully.

Key takeaways​

  • Sequence-of-returns risk is the danger that large portfolio losses coincide with required withdrawals, forcing you to sell at low prices
  • Bonds reduce sequence risk by providing ballast; a 50% stock allocation in retirement is far safer than 50% in accumulated savings
  • The bond allocation should cover 2–5 years of withdrawals, held in Treasuries or IG bonds to guarantee availability
  • TIPS protect your purchasing power in long retirements; nominal bonds protect in normal-inflation scenarios
  • Most retirees benefit from 40–60% bond allocation, not the 60–70% suggested for pre-retirees

Sequence risk: the retirement-specific danger​

A 35-year-old with a $1 million portfolio can afford a 40% decline. They have 30 years of compound growth ahead. Even if the portfolio falls to $600k, it can recover to $2–3 million by age 65 if equities average 7% returns. Sequence risk is abstract.

A 65-year-old with a $1 million portfolio faces a different arithmetic. They need 4% withdrawals ($40k per year), and they have only 25–30 years of investment horizon. If the portfolio falls 40% to $600k in year one of retirement, they've now spent $40k in withdrawals while experiencing a $400k loss. Their $600k portfolio must now generate 6.7% to sustain $40k withdrawals. This is mathematically dangerous.

Consider two 65-year-olds with identical $1 million portfolios and identical 60/40 allocations:

Scenario A (Bad luck): 2008 hits immediately. Stocks fall 37%, bonds gain 15%. Year 1 ending balance: $940k (60% x -37% + 40% x 15% = -22.2% + 6% = -16.2%). The retiree withdraws $40k, leaving $900k.

Scenario B (Good luck): Stocks gain 15%, bonds gain 5%. Year 1 ending balance: $1,090k (60% x 15% + 40% x 5% = 9% + 2% = 11%). The retiree withdraws $40k, leaving $1,050k.

After 30 years of retirement, Scenario A leaves the heirs roughly $500k (due to compounding on a smaller base). Scenario B leaves the heirs roughly $1.8 million. The difference in outcomes is not noise—it is existential.

This is sequence risk: the luck of when returns happen is as important as the average return itself.

How bonds reduce sequence risk​

Bonds reduce sequence risk by:

  1. Providing ballast that gains when stocks crash, funding withdrawals without forced selling.
  2. Allowing retirees to skip equity sales in downturns by drawing from bonds instead.
  3. Reducing overall portfolio volatility, making drawdowns shallower.

The mechanism is straightforward. A 60/40 portfolio falls 22% in a crash (60% x -37% + 40% x 15% = -16.2%). A 50/50 portfolio falls 17%. A 40/60 portfolio falls 11%. If you can afford the 2–3% annual return drag, the lower volatility means you spend fewer down years selling equities at distressed prices.

The optimal bond allocation for a retiree depends on:

  • Years until death (or giving up control). A 65-year-old planning to live to 95 has 30 years. A 75-year-old planning to live to 95 has 20 years.
  • Withdrawal rate. A 3% withdrawal rate is easier to sustain than 5%. The lower the withdrawal rate, the lower your bond allocation needs to be.
  • Volatility tolerance. Some retirees can handle a 25% decline; others panic at 15%.
  • Other income sources. If you have Social Security, pensions, or rental income covering 60% of expenses, you can afford higher equity exposure in the portfolio.

The bond ladder approach: 2–5 years of withdrawals​

The safest approach for retirees is to build a bond ladder with 2–5 years of withdrawal needs:

If you need $50k per year (from a $1.25M portfolio using the 4% rule), build a bond ladder:

  • Year 1: $50k in 1-year Treasury or short-term bond fund
  • Year 2: $50k in 2-year Treasury
  • Year 3: $50k in 3-year Treasury
  • Year 4: $50k in 4-year Treasury
  • Year 5: $50k in 5-year Treasury

Total bond ladder: $250k (20% of portfolio). The remaining $1M (80%) is in equities.

This approach guarantees that you never have to sell equities for the next 5 years, no matter how bad the market is. Even in a 2008-like crash, you withdraw from the maturing Treasury each year. By year 5, if the market has recovered (as it historically does), equities are back to $1.5M+, and you can rebalance by building a new ladder.

If you want to cover more withdrawals (say, 7–10 years), extend the ladder:

  • Years 1–10: $50k in 1–10 year Treasuries
  • Total ladder: $500k (40% of $1.25M portfolio)

This is more conservative but guarantees 10 years of income without selling equities.

Allocation by age and circumstances​

Age 60–65 (pre-retirement):

  • 60% equities, 40% bonds. Use this 3–5 years before retirement to build up bond reserves while still capturing equity growth.

Age 65–75 (early retirement):

  • 40–50% equities, 50–60% bonds. Prioritize stability. Withdrawals are high relative to total portfolio. Sequence risk is acute. A 50/50 portfolio has expected volatility of 8–10% and can weather most downturns.

Age 75–85 (established retirement):

  • 30–40% equities, 60–70% bonds. If the portfolio has survived the first 10 years of withdrawal, you've passed the highest-risk period (early-retirement sequence risk). You can afford to trend more conservative as time horizon shortens. A 35/65 portfolio has expected volatility of 5–7%.

Age 85+ (late retirement):

  • 20–30% equities, 70–80% bonds. Simplify for heirs. Prioritize stability and capital preservation. A 25/75 portfolio has expected volatility of 3–5%.

TIPS vs nominal bonds for retirees​

Retirees benefit from TIPS because they protect purchasing power over a 25–30 year retirement. If inflation averages 3% over a 30-year retirement, a $1 million portfolio of nominal bonds loses 60% of purchasing power (in real terms), while a TIPS portfolio maintains purchasing power.

However, TIPS have tax complications in taxable accounts (the annual inflation adjustment is taxed as income). For a retiree with a $1 million portfolio allocated:

  • $400k bonds in a Roth IRA or traditional IRA: use TIPS (tax-deferred)
  • $400k bonds in a taxable brokerage: use nominal bonds or short-term Treasuries (tax-efficient)
  • $200k cash in a brokerage: use money market funds or 6-month Treasury bills

This structure provides inflation protection on tax-deferred bonds while avoiding tax drag on taxable bonds.

The withdrawal strategy: draw from bonds first​

A crucial rule for sequence-risk management: draw from bonds first in early retirement.

Year 1: Withdraw $50k from maturing bond ladder. Don't touch equities. Year 2: Withdraw $50k from next maturing bond rung. Equities continue compounding undisturbed.

If the market crashes in year 3, you've already spent 2 years of withdrawals from bonds. You still have 3+ years of bond runway before you must touch equities. The crash matters less because time heals drawdowns.

In contrast, a retiree who withdraws from equities in year 1 (or worse, in a down market) locks in losses and never recovers that capital.

Case study: 2008 and 2009 sequence risk​

Consider a retiree with $1M portfolio, 50/50 equities and bonds, retiring in October 2007 (just before the crash):

Scenario 1: Withdraws from equities (wrong):

  • October 2007: Portfolio $1M (500k stocks, 500k bonds). Withdraws $30k from stocks, leaving 470k stocks.
  • December 2008: Stocks fell 37%. Portfolio now $831k (470k x 0.63 + 500k x 1.05). Withdraws $30k more from stocks, leaving 427k.
  • By 2012 recovery: Portfolio worth roughly $950k despite 4 years of withdrawals.

Scenario 2: Withdraws from bonds (correct):

  • October 2007: Portfolio $1M. Withdraws $30k from bonds, leaving 470k bonds.
  • December 2008: Portfolio $931k (500k x 0.63 + 470k x 1.05). Withdraws $30k from bonds.
  • By 2012 recovery: Portfolio worth roughly $1,100k despite 4 years of withdrawals.

The difference is only $150k, but that's a 16% difference in final portfolio value. The retiree who drew from bonds stayed invested in equities through the recovery and captured the 100%+ upside from 2009–2012 (stocks tripled). The retiree who drew from equities had less capital growing during recovery.

The simplest approach: target-date funds for retirees​

For simplicity, Vanguard and Fidelity offer target-date funds specifically designed for retirees:

  • Vanguard Target Retirement Income (for people already retired): 40–50% stocks, 50–60% bonds
  • Fidelity Freedom Index K Income (for people already retired): 40–45% stocks, 55–60% bonds

These funds automatically rebalance and gradually shift more conservative as time goes on. They are not perfect, but they handle much of the sequence-risk management for you.
