Guardrails Against Sequence Risk

If the market falls right after you quit, withdrawals can lock in losses and shrink what you can safely spend forever. A big drop in the first few years matters more than the same drop later, so early protection is key.

Begin FIRE with 1-2 years of expenses in cash or short Treasuries. Consider a slightly calmer mix, like 65/35 instead of 80/20, for your first 2-3 years. Once you are past the riskiest window, you can move back toward your long-term mix.

Set simple rules so you do not guess under stress. Example: if your portfolio drops 20% from its peak, cut spending by 10-15% and skip inflation raises; if it rises 20%, give yourself a small raise. Guardrails add flexibility without daily tinkering.

After markets bounce back, refill your cash buffer first, then rebalance to your target mix. If you paused inflation raises, restart them only after your portfolio makes a new high. Survival first, then comfort.

Any steady income helps: part-time work, small rentals, or later Social Security. The more steady cash you have, the smaller your buffer can be. If you plan to claim Social Security at 70, you can withdraw a bit more before 70 and less after checks start.
