- Lucas: Picture this: it's late 2021, and you've just retired early with a million-dollar portfolio. You're confident in your 4 percent withdrawal rate. Then 2022 happens — stocks drop 20 percent, bonds drop 15 percent. By the end of the year, your portfolio is worth $800,000, and you've already withdrawn $40,000. That sequence of returns just slashed your long-term survival odds. Luna: That's the classic sequence of returns risk that we've talked about before. But what if you didn't have to sell into that downturn? Lucas: Exactly. That's where a dedicated cash buffer comes in. Instead of selling stocks or bonds each month for living expenses, you hold two years of cash — say $80,000 for a $40,000 annual spend — and you draw from that during bad markets. You only replenish it during good years. Luna: So the idea is that you avoid selling low. In our 2022 scenario, you'd have used cash rather than liquidating equities at the bottom. Lucas: Right. And it's not just theory. Wade Pfau, a retirement researcher, ran the numbers in a 2016 study. He found that a two-year cash buffer improved the sustainable withdrawal rate by about 0.5 to 1 percent for a 30-year retirement. For early retirees looking at 40 or 50 years, that buffer can be even more critical. Luna: But isn't there a cost? Cash earns close to zero in real terms. Over a long retirement, that drag on returns could hurt. Lucas: That's the trade-off. You're accepting lower average returns in exchange for lower sequence risk. But here's the key: the buffer isn't permanent. In good years — say the market is up 15 percent — you rebuild the cash bucket by selling some appreciated assets. So the idle cash isn't sitting there for decades. It gets deployed and replenished. Luna: What about the behavioral side? I imagine it's tough to keep drawing cash when the market is down and your portfolio is shrinking. You might panic. Lucas: That's actually a huge benefit of the buffer. If you've already set aside that cash, you don't have to make a decision during a downturn. You just spend from the money market account. It removes the emotional pressure of selling when stocks are falling. The hardest part is sticking to the replenishment rule — selling when the market is high feels counterintuitive to some retirees. Luna: So how do you decide the size of the buffer? Is two years the magic number? Lucas: It depends on your risk tolerance and spending flexibility. Some researchers recommend one to three years. The idea is to cover a typical bear market recovery period — historically, stocks have recovered within two years on average. But for early retirees, I lean toward two to three years, because you have a longer horizon and less ability to go back to work. Luna: And what about replenishment? Do you have a specific rule? Lucas: There are a few approaches. One is to wait until your portfolio exceeds its initial value by a certain percentage — say 10 percent above the starting balance. Then you sell just enough to refill the cash buffer. Another is to do it annually: at the end of a year when the market is up, you top up the cash account. The key is not to replenish during down years. Luna: That makes sense. But it also means that in a prolonged bear market, you might run out of cash before the market recovers. Then you're forced to sell anyway. Lucas: Right, and that's the risk. A two-year buffer covers the typical bear, but not the Great Depression or the 2000–2002 dot-com crash, which lasted three years. So you want to pair the cash buffer with some spending flexibility. If the market is still down after two years, you cut spending by 10 or 20 percent — that extends the buffer further. Luna: That's a good point. It's not a silver bullet, but it's a practical tool. I think a lot of early retirees overlook it because they're focused on maximizing returns. Lucas: Exactly. The obsession with total return often blinds people to the benefits of liquidity. But think about it: if you're selling stocks at a 20 percent loss, you need a 25 percent gain just to break even. Avoiding that loss is worth more than the interest you'd earn on cash. In Pfau's research, the survival probability for a 4 percent withdrawal rate over 30 years went from about 95 percent to over 99 percent with a two-year buffer. Luna: And I imagine that matters even more for someone retiring at 45 versus 65. They have to survive 40 or 50 years. Lucas: Exactly. And that's really what this show is about — giving people practical strategies to make early retirement work. Speaking of which, I want to take a quick moment to mention something. A number of listeners in our community chip in monthly through buy me a coffee dot com slash fexingo, and that's what allows us to keep this podcast going without any ads or sponsors. Luna: Yeah, it's pretty amazing. We get to make exactly the episodes we think are most useful, and we don't have to worry about selling anything to you. So thanks to everyone who supports the show. Lucas: Alright, back to the cash buffer. So let's talk about how to actually implement this in a portfolio. You don't want to just keep $80,000 in a checking account earning nothing. Luna: What do you recommend? High-yield savings? Money market funds? Short-term Treasuries? Lucas: All of the above. In 2026, with interest rates where they are, a high-yield savings account or a money market fund is earning around 4 to 5 percent. That's actually not bad. You could also build a small Treasury bill ladder — three-month, six-month, one-year — to get a slightly higher yield while keeping the cash accessible. The point is, the buffer should be in something low-risk and liquid. Luna: And you want to keep it separate from your emergency fund, right? Because if you have a big unexpected expense and your cash buffer is gone, you're back to selling. Lucas: Yes, that's a crucial distinction. Your cash buffer is for planned spending — the $40,000 a year you budgeted for. You should have a separate emergency fund for true emergencies, like a major home repair or medical bill. Otherwise, one bad car accident could blow through your buffer and force you to sell at the worst time. Luna: So you're essentially running a modified bucket strategy: a cash bucket for the next two years, a bond bucket for years three to five, and equities for the long term. Lucas: Exactly. The cash bucket is the first line of defense. The bond bucket — short-term bonds or a bond ladder — covers the intermediate term. And equities are for growth over the long haul. When the market is up, you replenish the cash bucket from equities. When it's down, you let it run down and refill later. That's the classic bucket approach popularized by people like Ray Lucia. Luna: Critics say bucket strategies are just mental accounting — that you're better off with a total portfolio approach that rebalances automatically. Lucas: That's a fair criticism. Financially, a cash buffer is slightly less efficient than a perfectly executed rebalancing strategy. But behaviorally, it's much easier to stick with. Most early retirees are better off with a simple system they won't mess up than a theoretically optimal one they'll abandon in a panic. Luna: And given that the biggest risk in early retirement is often the retiree themselves — their emotions — that behavioral benefit is real. Lucas: Exactly. So to wrap up: if you're planning to retire early, consider setting aside one to three years of living expenses in cash or cash equivalents. It might lower your expected returns by a fraction of a percent, but it can dramatically increase the odds that your portfolio lasts as long as you do. In the world of early retirement, that's a trade-off worth making. Luna: And with that, we've covered another tool for the FIRE toolbox. I'm Luna. Lucas: And I'm Lucas. Thanks for being here.
