Posting to follow. I intend to have a cash buffer worth two years of expenses when I FIRE but haven't get defined what would trigger using it. Appreciate the input.
yes - this seems tricky to me. On one hand, spending as soon as the market begins to really weaken, 2 years would cover most downturns. On the other hand - when 2 years doesn't cover the downturn, one would have been best off not spending the cash piece the first year.
I get these questions all the time, and here's some discussion points.
First, it's only two years' expenses in cash. With the 4% Safe Withdrawal Rate, that's only 8% of the overall asset allocation, and it's not likely to make a significant difference in the portfolio's total return. The absolute "worst" case (100% equities) would be only getting 92% of the stock market's upside. If you have a high-equity asset allocation then it still might be 80% equities, 12% bonds, and 8% cash.
Second, it's only for the first decade of FI. By the end of the decade, even with keeping 8% in cash, investments should still grow faster than inflation and you'll be immune to sequence of returns risk.
As an example, someone starting their FI with $1M would spend $40K during the first year. At the end of the decade, spending would have grown with inflation but would still be $40K in today's dollars.
During that decade, a high-equity portfolio (at least 60% stocks) would grow faster than inflation. If the withdrawal rate at year #11 dropped from 4% over that decade to begin year #11 at 3.5% (which EarlyRetirementNow would agree is bullet-proof from sequence of returns risk), then the new investment value at year #11 to support that (in today's dollars) would have to be $40K / 3.5% = $1.143M.
To reach that value in a decade, it'd have to grow at an annual compound rate of only 1.4%/year faster than inflation.
Third, nobody knows how long the market downturn will last. There's no way to predict it, but no prediction is necessary.
The only thing you know is that you'll be able to let your cash stash get you through two years
without selling equity shares. Even if you start selling equity shares at the beginning of year #3 of the downturn, you've already given your equities two years of breathing room by skipping sales of those shares.
Finally, after two years of a bear market or a recession, you still have the options of:
- cutting spending or
- seeking part-time work or
- if you're eligible, starting Social Security at age 62.
Our first decade of retirement was 2002-2012, which meant that we got to test this two-year cash stash through two significant recessions.
Ironically, we didn't cut our spending during those recessions because corporations couldn't raise prices. Better yet, we were able to score bargains in our lifestyle areas like home improvement (contractors) and travel (discounted airfares & lodging). We spent the money we would normally spend and actually received more value from it.
A financially-independent person seeking part-time employment during a recession doesn't need much money. Spending $40K/year means that even $5000 is more than 10% of your annual expenses. During a recession, employers don't want to hire people full-time because they can't afford them. However they'd love to hire part-time employees because they don't need to give them benefits like 401(k)s or health insurance. This means there are plenty of part-time jobs during recessions, and it doesn't take much part-time work to earn the money to give your investments time to recover.
If you're financially independent, maybe you should actually be
hoping for a nasty recession during that first decade. You'll probably get more value for your spending, you'll have more opportunities to work (if you want), and you won't be at a full-time job where you're worrying about layoffs or picking up the bigger workload after others are laid off.
Based on the last century or so, a nasty recession will probably happen during that first decade anyway.
If a 4% SWR portfolio fails from sequence of returns risk, it still lasts for at least 20 years (most of the failures happen after year 24). This means that someone reaching FI before their early 30s (30 years from Social Security) would have to be concerned about a recession so prolonged that their investments couldn't survive even after using the cash stash, then (2-3 years later) cutting expenses and seeking part-time employment, and then not making it to Social Security at age 62.
If we encounter a recession that bad, I'd hate to be stuck in the workplace environment of a full-time job. Why, for that sort of meteor-strike extinction-level catastrophe, it'd take something like... oh, I don't know... maybe a global pandemic.
On another popular FI forum, we'd refer to this level of concern as the analogy of keeping your pants around your waist by relying on a belt, a set of suspenders, and a nailgun.
To summarize:
Once you reach the tripwire of FI (assets of 25x annual expenses), then how much longer would you feel obligated to trade your life energy (which you might not have) for more money (which you almost certainly will not need)?
