Your 401(k) in a recession.

A recession is a number on a chart until it is the number on your quarterly statement. Move your balance, move your mix, and see what the last three did to a portfolio shaped like yours.

— Your 401(k), three recessions

Set your current balance and your stock/bond/cash mix. We apply the actual peak-to-trough S&P 500 drawdown from each of the last three U.S. recessions to your stock sleeve, cushion by the bond rally the Fed tends to engineer, and leave cash flat. The dollar number underneath each scenario is what the low print on your statement would have said.

In the Financial crisis (2007-2009), your $250,000 would have printed a low of

a loss of $61,625 (−24.6%). On the prior-peak recovery clock that episode then ran 60 months.

— How long to recover

6 months in the pandemic crash (2020). 60 months in the financial crisis (2007-2009).

The recovery window is how long the index took to print its prior peak again. It is not the same thing as the recession being over. The 2020 case ran six months end-to-end. The dot-com case ran multiple years. If you sold at the low in either one you missed the part where the market made you whole. The contribution you make on the way down buys shares at a discount that the rest of the chart does not offer.

— What to do (and not do) in a recession

None of this is advice. It is the common wisdom, written down, with the failure modes on the other side of each line. The failure modes are the interesting part.

  • Keep contributing through the drop.

    Every paycheck on the way down buys more shares than the same paycheck on the way up. That is the entire argument for dollar-cost averaging, and it only works if the payroll deduction keeps firing.

  • Do not sell the whole portfolio.

    Cash is easy to get to and famously hard to get out of. The re-entry trigger rarely gets pulled at the right moment. The people who sold in March 2020 mostly watched the recovery from the sidelines.

  • Rebalance to targets, not to feelings.

    If stocks dropped and your 70/30 is now a 58/42, rebalancing means buying more stocks at the lower price. It feels wrong in the moment. It is the whole point of having a target.

  • Keep the emergency fund separate.

    Six months of expenses in a money-market account is not the same pot as retirement. If you are forced to withdraw from the 401(k) during a drawdown, you are locking the loss and paying the early-withdrawal penalty too.

The same drawdown series, with a cleaner radio-button scenario UI and a 60/40 default, lives at the recession stress test. If you want the recession label itself, what NBER actually measures, and whether the current data is flashing one, start at recession.
