Latest / The Emergency Fund Podcast with Fexingo: Cash Reserves, Saving, and Financial Cushion / Should You Invest Your Emergency Fund
Transcript
- Lucas: Let me start with a number that's been sticking in my head. If you've got a typical fifteen thousand dollar emergency fund sitting in a checking account earning zero percent, and inflation runs at four percent — which is roughly where it's been — that fund just lost about six hundred dollars of purchasing power over the past year. Luna: Ouch. And that's not even accounting for what you could have earned if that money were invested. Lucas: Exactly. That's the opportunity cost argument we hear more and more from the FIRE community and a lot of younger investors. The logic goes: if your emergency fund is earning nothing, you're leaving money on the table. Why not put it in the market and get a real return? Luna: And there's a counterargument that's equally loud: you don't invest money you might need tomorrow. That's the whole point of an emergency fund. Lucas: Right. So today I want to push past the slogan and actually look at the trade-offs with real numbers and a specific strategy. Because I think there is a middle ground that preserves the cushion while earning something. Luna: I'm in. Let's start with the base case. What does a conventional emergency fund look like in May 2026? Lucas: The standard advice is three to six months of essential expenses in a high-yield savings account or money market fund. And right now, with the Fed funds rate at 4.5 percent after the last rate hold, you can actually earn decent interest. Ally, Marcus, and SoFi are all offering around 4.3 to 4.5 percent on savings. Luna: So if you use a high-yield savings account, you're basically keeping pace with inflation. That's not nothing. Lucas: It's close. But a lot of people still keep their emergency cash in a brick and mortar checking account earning zero. And that's where the opportunity cost really bites. Luna: So the first step is just moving the money, right? Before we even talk about investing. Lucas: Absolutely. But let me play devil's advocate for the investing crowd. If instead of earning four percent, you put that fifteen thousand into the S&P 500, the long-term average return is about ten percent. Over a decade, the difference is roughly ten thousand dollars. Luna: But the problem is that emergencies don't happen on a ten-year schedule. They happen next month. Lucas: That's the crux. If you need that money during a market downturn — and the worst employment shocks often coincide with bear markets — you're selling stocks at a loss. That's the opposite of financial security. Luna: There's actually a great 2023 Morningstar paper on this. They looked at the worst-case scenario for investors who put their emergency fund in equities. If you had to withdraw during the 2008 crash, your fund would have lost nearly forty percent of its value. Lucas: Right. And that's not an emergency fund anymore. That's a disaster fund that turns into a smaller disaster. Luna: So what's the middle ground you mentioned? Lucas: A tiered approach. Keep one to two months of expenses in something completely liquid — a checking account or a no-penalty CD. Then put the next two to three months in a high-yield savings account or a short-term Treasury ETF like SGOV, which currently yields about 4.6 percent and is effectively as safe as cash. Luna: SGOV — that's the iShares 0-3 Month Treasury Bond ETF, right? Lucas: Yes. It's basically a wrapper for T-bills. You get the yield of Treasuries with same-day liquidity. The catch is that it's not FDIC insured, but the underlying assets are U.S. government obligations. Luna: And for the rest? If someone wants to be more aggressive? Lucas: If you have a larger cushion — say, six months or more — you could consider putting the portion beyond month four into a short-term bond fund or a ladder of CDs with staggered maturities. That way you're earning a bit more while still having money coming due regularly. Luna: I've seen people argue for putting emergency funds in a Roth IRA. You can withdraw contributions anytime without penalty. Lucas: That's a valid strategy for someone who's already maxing out their retirement savings, but it's risky. If you raid your Roth for an emergency, you're sacrificing future tax-free growth. And if the market drops, your contribution might be worth less when you need it. Luna: So the takeaway is: earn something, but don't gamble. Lucas: Exactly. There's a concept called the 'sleep well at night' premium. The cost of having your cash earn four percent instead of eight percent is the price you pay for knowing it's there when you need it. And for most people, that's worth it. Luna: Speaking of which, Fidelity just launched a new cash management account in March that offers 4.7 percent on balances up to fifty thousand. No fees, no minimums. Lucas: Yeah, I saw that. It's a sign that the big brokerages are competing for your emergency fund dollars. Schwab has their high-yield checking, Vanguard has their Cash Plus account. The options are better than ever. Luna: So for someone listening right now, what's the single action step? Lucas: Check what your emergency fund is earning today. If it's less than four percent, move it. Open a high-yield savings account — it takes fifteen minutes. Then decide if you want to build a tiered structure over time. Luna: And if you're tempted to go all in on stocks? Lucas: Remember the Morningstar paper. Remember that emergencies don't call ahead. Your emergency fund isn't an investment — it's insurance. And insurance isn't supposed to maximize returns. It's supposed to be there. Luna: Solid. So next time, maybe we talk about what happens after you actually use the emergency fund — how to rebuild. Lucas: That's a great angle. Because rebuilding is where a lot of people fall off. But for today, let's leave it here: earn something, sleep well.
