- Lucas: Alright, let me pitch you a scenario. You retire at fifty-five with a one-point-two-million-dollar portfolio. You've got a seventy-thirty split — stocks to bonds. And you're planning to withdraw four percent a year, which is forty-eight thousand dollars. That's your number. Luna: Classic four-percent-rule setup. So far so good. Lucas: Now, what happens if the market drops twenty-three percent in your first year? That's what actually happened in 2022. Your stocks go from eight hundred and forty thousand to roughly six hundred and forty-seven thousand. Your total portfolio shrinks to about nine hundred and sixty-seven thousand. And you still need to pull out forty-eight grand to live on. Luna: That's the sequence of returns nightmare. You're selling stocks at the bottom, locking in losses, and your portfolio might never recover. Lucas: Exactly. And the classic advice is: hold two years of cash so you never have to sell during a downturn. But that cash is earning next to nothing. Over thirty years, that drag can cost you hundreds of thousands in missed growth. So there's a tension — safety versus growth. Luna: That's the puzzle I think a lot of early retirees wrestle with. How do you get the safety without sacrificing the compounding? Lucas: Before we dive into the mechanics — and I promise we will — I want to say something honestly. A handful of listeners chip in monthly through buy me a coffee dot com slash fexingo, and that's literally what funds us making episodes like this without ads. Luna: Yeah. And it's not a big ask — it's just a small way people who find these conversations useful can keep them going. We really appreciate it. Lucas: So — back to the cash cushion. The strategy I want to walk through is what some people call a 'dynamic cash reserve.' The idea is: you keep a smaller buffer — say, eighteen months of expenses — but you only refill it when the market is up. Luna: Eighteen months. So in our example, that's about seventy-two thousand dollars. How do you hold it? Lucas: Split it. Put six months — twenty-four grand — in a high-yield savings account currently yielding around four and a half percent. The other twelve months — forty-eight thousand — in a short-term bond ETF like SGOV or BIL, which is yielding around five and a quarter percent. Combined, you're earning roughly five percent on your cash, so it's keeping pace with inflation. Luna: So you're not losing purchasing power while it sits there. That's better than the typical 'cash under the mattress' approach. Lucas: Right. Now here's the critical rule: during a down year, you spend from the cash reserve first. You do not touch your stock portfolio. In 2022, you would have drawn down that seventy-two thousand dollars over the year. By the end of the year, you'd have used maybe forty-eight thousand of it, leaving twenty-four thousand. Luna: So your stocks stay untouched, and they get to recover fully when the market bounces back. What about the next year? Lucas: Let's say 2023 was a good year — the S&P 500 was up about twenty-four percent. By the end of 2023, your stock portfolio has recovered to about eight hundred thousand. Now you refill the cash reserve. You sell maybe sixty thousand dollars worth of stocks — but only the ones that have appreciated, and you're mindful of capital gains. Luna: But doesn't selling stocks trigger a tax bill? You'd have to pay capital gains on those sales. Lucas: Great question. Here's the trick: you refill the cash reserve gradually, over several months, and you prioritize selling lots with the lowest gains — or even tax-loss harvest from earlier losses. In practice, if you're strategic, you can keep the tax impact minimal. And remember, if your taxable income is low in early retirement, you might be in the zero percent capital gains bracket. Luna: Right. For a married couple filing jointly in 2026, the zero percent bracket goes up to about ninety-four thousand dollars in taxable income. So if your total income is below that, you pay zero federal tax on those gains. Lucas: Exactly. So the dynamic buffer actually works with the tax code. Now, what about the size of the buffer? Why eighteen months and not twelve or twenty-four? Luna: I'm guessing it's related to the typical length of a bear market. Lucas: Bingo. The average bear market since 1929 has lasted about fourteen months. Eighteen months covers the average and gives you a little extra margin. If you had twenty-four months, you'd be holding more cash than necessary, and over thirty years that extra cash might cost you about one hundred and fifty thousand dollars in missed growth, assuming a seven percent return. Luna: So there's a real cost to being too conservative. What about the replenishment rule? How do you know when to refill? Lucas: The rule is simple: only refill when your portfolio is at or above its previous all-time high. That ensures you're selling high, not low. You don't refill during a partial recovery. If the market goes up ten percent but is still fifteen percent below the peak, you wait. Patience is key. Luna: That makes sense emotionally, too. It prevents you from getting impatient and selling too early. But what if the market stays down for longer than eighteen months? Lucas: It's happened — the 2000 dot-com crash lasted about two and a half years. In that case, you'd have to tap your bond portfolio after the cash reserve runs out. But here's the thing: your seventy-thirty split means you have about three hundred and sixty thousand in bonds. You can spend from those for a while. And bonds typically hold up better in downturns. Luna: But bonds also got hammered in 2022. The Bloomberg Aggregate Bond Index was down about thirteen percent. Lucas: True. But a short-term bond ETF like BIL actually held up much better — it was only down about one percent in 2022. So the choice of bond vehicle matters. For the cash reserve, stick with very short duration. For the bond portion of your portfolio, you might consider a mix of short-term and intermediate-term to get a bit more yield. Luna: So the overall withdrawal order is: first the cash reserve, then bonds, then stocks only as a last resort. Lucas: Exactly. And that order alone — selling cash and bonds first instead of stocks — can boost your portfolio's survival rate by five to ten percentage points over a thirty-year retirement, according to research by Wade Pfau and others. Luna: I want to run a quick back of the envelope on our example. Starting with one point two million, seventy-thirty split. First year, market drops twenty-three percent. You spend forty-eight thousand from cash. Your cash reserve drops from seventy-two thousand to twenty-four thousand. Your stocks are at six hundred forty-seven thousand, your bonds are at three hundred sixty thousand. Total portfolio: about one point zero three one million. Lucas: Correct. And in year two, the market recovers twenty-four percent. Your stocks go from six hundred forty-seven thousand to about eight hundred and two thousand. Your bonds maybe earn five percent, so they go to three hundred seventy-eight thousand. Total portfolio: one point one eight million. Now you refill the cash reserve by selling sixty thousand from stocks — but you only do it if the market is at a new high. In this case, your stocks are still below their original eight hundred forty thousand, so you might wait. Luna: So you'd have to live off the remaining cash and bonds for another year? That would be tight. Lucas: It would be. But if the market continues to recover, by year three you might be back to even. And you can refill then. The key is you never sell stocks at a loss. You might have to tighten your belt a little, but you avoid the permanent portfolio damage. Luna: So the dynamic cash reserve is essentially a buffer that lets you avoid selling low, but it's not a guarantee that you'll never have to adjust your spending. Lucas: Right. And that's why it pairs well with a variable withdrawal strategy. If the market is down, you might cut spending by ten percent. The cash reserve gives you time to adjust without panic. Luna: I like that. It's a system that builds in flexibility rather than a rigid rule. What about the mechanics of setting it up? How do you actually create the cash reserve at retirement? Lucas: Ideally, you build it in the five years before you retire. You gradually shift a portion of your portfolio from stocks to cash. If you're still working, you can direct new contributions to the cash reserve. If you're already retired, you can sell some bonds or stocks in a tax-efficient way — maybe over a few years to spread out the tax hit. Luna: And what if you're already retired and you don't have a cash reserve? Can you build one now? Lucas: Absolutely. If the market is up, sell a little from your winners each year and build it over two to three years. If the market is down, wait. The worst time to build a cash reserve is during a downturn, because you're selling at the bottom. So be patient. Luna: So the strategy is really about timing — not market timing, but withdrawal timing. Sell when you have gains, spend from cash when you don't. Lucas: That's the essence. And it's surprisingly simple once you set it up. You just need two accounts — a high-yield savings and a short-term bond ETF — and a rule about when to refill. No complex algorithms. Luna: I think the hardest part is psychological. It's tempting to refill the cash reserve when the market is only halfway back, because you feel like you need the security. Lucas: Absolutely. That's the discipline. You have to trust the system. But if you run the numbers, it's clear that refilling only at all-time highs gives you the best long-term outcome. The research backs it up. Luna: So for someone listening who's five years from retirement, what's the one takeaway? Lucas: Start building your cash reserve now. Aim for twelve to eighteen months of expenses in a mix of high-yield savings and short-term bonds. And commit to the rule: spend from cash in down markets, refill in up markets. It's that simple, and it can add years to your portfolio's life. Luna: And if you're already retired and haven't done this, it's not too late. Start by selling a little from your winners this year, and build that buffer over time. Lucas: Exactly. The goal isn't to time the market perfectly — it's to build a system that protects you from your own worst impulses. Luna: Alright, that's a solid framework. I'm going to look at my own withdrawal plan this weekend. Lucas: Do it. And if you want, we can follow up in a future episode with a deep dive on how to tax-loss harvest while building your cash reserve. Luna: I'd love that. For now, thanks for walking through this — really practical stuff. Lucas: Happy to. That's all for today — go enjoy that iced coffee on the porch.
