Bonds in FIRE: When and How Much

Bonds in FIRE: When and How Much

The role of bonds in a FIRE portfolio sparks endless debate. On one side: bonds provide stability and reduce volatility. On the other: lower expected returns mean you need to save more to reach your target number. Finding the right balance depends on your timeline, risk tolerance, and how close you are to your FIRE date.

Here's a framework for thinking through bond allocation at different stages of your FIRE journey.

The Accumulation Phase

When you're decades from FIRE with a long investment horizon, maximum stock exposure often makes sense. Market downturns, while painful, provide opportunities to buy shares at lower prices. Your ongoing contributions dollar-cost average through volatility. Time heals most market wounds.

Many FIRE pursuers in their 20s and 30s maintain 90% or even 100% stock allocations during this phase. The math supports this approach: higher expected returns compound over decades, potentially shaving years off your working career.

However, this aggressive stance only works if you can actually stick with it. A 100% stock portfolio might drop 50% or more in a severe downturn. If seeing your balance cut in half would cause you to sell in panic, a small bond allocation provides psychological protection that keeps you invested.

Approaching FIRE (5-10 Years Out)

As you get closer to your FIRE date, sequence of returns risk becomes a real concern. A major market decline in the years just before or after you stop working can significantly impact your portfolio's longevity. You no longer have decades to recover, and you might not have ongoing income to buy the dip.

This is when gradually increasing bond allocation makes sense for many FIRE planners. Moving from aggressive to moderate might mean shifting from 10% bonds to 20-30% bonds over several years. The exact numbers depend on your risk tolerance and flexibility around your FIRE date.

Some FIRE planners use a "bond tent" approach, temporarily increasing bond allocation to 40% or higher right around retirement, then gradually reducing it over time. This protects against the most dangerous years for sequence risk while still allowing growth in later retirement.

In Retirement

Traditional retirement advice suggests high bond allocations (60-70%) for retirees. But FIRE retirements can last 40-50 years, and too little growth exposure creates its own risk: running out of money because your portfolio couldn't keep pace with inflation.

Many FIRE retirees settle on something like 60-75% stocks and 25-40% bonds, far more aggressive than traditional retirement portfolios but more conservative than their accumulation phase. This balances growth needs with volatility reduction.

The Flexibility Factor

Your ideal bond allocation also depends on how flexible your FIRE plan is. If you have:

A paid-off home, pension income, or ability to return to work: You might handle more volatility, allowing for lower bond allocation.

Fixed expenses, no backup income source, or health issues preventing return to work: A higher bond allocation provides more stability when you need it.

A lean FIRE budget with minimal margin: Conservative allocations protect against having to cut an already minimal lifestyle.

Practical Guidelines

While everyone's situation differs, here are some starting points:

During accumulation (10+ years from FIRE): 0-20% bonds, depending on risk tolerance.

Approaching FIRE (5-10 years out): Gradually increase to 20-30% bonds.

At and near FIRE date: Consider 30-40% bonds to protect against sequence risk.

Early FIRE retirement: Settle into a long-term allocation of 25-40% bonds, adjusting based on market conditions and personal circumstances.

These are guidelines, not rules. Your allocation should reflect your specific situation, including other income sources, spending flexibility, and psychological ability to handle volatility.
