# Building a Treasury Buffer Before Retirement Protects You From Early Market Crashes
The first five years after you retire matter more than most investors realize. A sharp market decline during that window can force you to sell stocks at depressed prices to cover living expenses, locking in losses that haunt your portfolio for decades. One proven defense: build a cash reserve of short-term Treasury securities before you leave your job.
This strategy, sometimes called a "war chest" or "bucket strategy," addresses a real retirement risk. Consider a retiree who retires in year one of a bear market. If their portfolio drops 30 percent and they need to withdraw $50,000 for living costs, they're forced to sell holdings when valuations are lowest. That $50,000 withdrawal takes a much larger chunk of their remaining portfolio than it would in a normal year. The damage compounds over time.
Short-term Treasuries serve as your emergency fund on steroids. These securities include Treasury bills (T-bills) maturing in weeks to months and short-term Treasury notes maturing in one to three years. As of late 2024, Treasury bills yield between 4.5 and 5.3 percent depending on maturity, while two-year Treasury notes offer around 4.0 to 4.2 percent. These rates give you real returns with zero credit risk.
The mechanics work this way. Build your war chest while still employed, when consistent paychecks let you save aggressively. Aim for 2 to 3 years of living expenses in short-term Treasuries. If you spend $60,000 yearly, target $120,000 to $180,000 in this reserve. You can buy Treasury bills directly through TreasuryDirect.gov at no cost, or purchase them through any major brokerage like Fidelity, Charles Schwab, or Vanguard.
When you retire and markets fall, you don't sell stocks. Instead, you live off your Treasury reserve. Your stock portfolio stays intact, continuing to compound. When markets recover, your remaining stocks bounce back at full strength. You've avoided locking in losses during the downturn.
This approach works because market downturns early in retirement carry outsize risk. A 30 percent decline in year one costs you far more than the same decline in year ten. Money withdrawn in year one never has time to recover. Money you don't touch in year ten can still grow for 20+ years.
The trade-off is modest. Treasury returns (around 4.5 percent currently) lag stock returns over long periods. But you're paying a small insurance premium in exchange for sequence-of-returns protection. You're also sleeping better knowing you won't face forced selling during market chaos.
The strategy works best if you start building your war chest three to five years before retirement. Consistent monthly contributions to short-term Treasuries compound your returns while filling the reserve gradually. A 55-year-old planning to retire at 62 has seven years to build this cushion without aggressive saving.
Market timing matters less with this approach. You're not trying to predict crashes. You're simply reducing your vulnerability when one strikes. Time it right, and a downturn that would derail a traditional portfolio becomes a minor inconvenience.
