Latest / The Emergency Fund Podcast with Fexingo: Cash Reserves, Saving, and Financial Cushion / Where Should You Keep Your Emergency Fund
Transcript
- Lucas: So you've built your emergency fund — three months, six months, maybe more depending on your situation. Great. Now the question nobody really answers well: where should that cash actually live? Luna: Right, because it can't just sit in your checking account earning zero, but it also can't be tied up in the stock market. There's a real tension there. Lucas: Exactly. The emergency fund has three non-negotiables: it has to be safe from market loss, it has to be liquid — meaning you can get to it within days, not weeks — and ideally it should earn something, even if that something is modest right now. Luna: And 'modest' is the word. As of this week in late May 2026, the top high-yield savings accounts are still hovering around 3.8 to 4.1 percent APY. That's down from the five percent peak we saw in 2023, but it's not nothing. Lucas: Yeah, the Fed's rate cuts have trickled through. But compared to the big bank checking accounts that pay zero point zero one percent — literally one basis point — there's still a huge gap. On a ten thousand dollar fund, that's roughly three hundred eighty dollars a year versus one dollar. Luna: So the first obvious stop is a high-yield savings account from an online bank. Ally, Marcus by Goldman Sachs, Capital One 360 — those names come up a lot. The question is, are they the best option? Lucas: They're the default for a reason. FDIC insured up to two hundred fifty thousand dollars, so your emergency fund is effectively risk-free on the credit side. You can withdraw money any time, typically with no fees, and transfers to your checking account take one to three business days. Luna: One to three days — that feels fast enough for most emergencies. But what about a true same-day need? If your car breaks down on a Saturday and you need cash right now? Lucas: That's where the tiered approach comes in. A lot of personal finance writers recommend keeping one month's worth of expenses in your regular checking account — earning nothing — just for that immediate access. Then the rest in the high-yield savings account, earning that four-ish percent. Luna: So you're essentially accepting a little dead money for convenience. That feels like a fair trade. But there are other options too, right? Money market funds? Lucas: Yeah, money market mutual funds are worth a look. These are offered by brokerages like Vanguard, Fidelity, Schwab. They invest in very short-term government debt, Treasury bills, that kind of thing. As of this week, the seven-day yield on a prime money market fund like Vanguard's is around 4.2 percent — slightly higher than savings accounts. Luna: And they're also very liquid. You can write checks from some of them, or just sell shares and have the money in your bank account in a day or two. Lucas: Right. But here's the nuance: money market funds are not FDIC insured. They're regulated by the SEC, and they've historically been very safe, but there's no government guarantee. In 2008, one fund 'broke the buck' — its net asset value fell below one dollar — and that caused a panic. The rules have tightened since, but it's still a distinction worth knowing. Luna: That's a fair point. For someone who wants absolute sleep-well-at-night safety, the FDIC insurance on a savings account might be worth giving up a tenth of a percent in yield. Lucas: Exactly. Then there's a third option that's been gaining popularity: short-term Treasury ETFs. Things like the iShares 1-3 Year Treasury Bond ETF, ticker s h y, or the shorter-duration SGOV, which holds Treasury bills less than three months to maturity. Luna: Those are traded like stocks, so you buy and sell them during market hours. The yield is tied to what short-term Treasuries are paying — right now around four and a quarter percent for three-month bills. Lucas: But again, not FDIC insured. Though they hold U.S. government debt, so the credit risk is essentially the same as the full faith and credit of the United States. The bigger issue is that the share price can fluctuate slightly — not like a stock crash, but a few cents up or down depending on interest rate moves. So if you need to sell on a day when rates spiked, you could get back slightly less than you put in. Luna: That's the thing — for an emergency fund, even a one percent temporary drop in principal could be annoying. Imagine you have fifteen thousand dollars in SGOV and the day your roof leaks, the ETF is down half a percent. You lose seventy-five bucks just because of timing. Lucas: Right. So for most people, the simplicity of a high-yield savings account wins. But there's a fourth option that's worth mentioning for the disciplined saver: Series I savings bonds, or I-bonds. Luna: I-bonds are interesting because they're inflation-protected. The rate resets every six months based on CPI. Right now, the composite rate is around 3.2 percent, so lower than the savings account, but the inflation protection means if inflation spikes again, your I-bond yield would follow. Lucas: The catch is liquidity. You can't redeem an I-bond at all in the first twelve months. And if you redeem within the first five years, you forfeit the last three months of interest. So they're really only suitable for the 'deep' portion of your emergency fund — the three-to-six-month portion you hope never to touch. Not for the money you might need next week. Luna: So you're describing a tiered system again: one month in checking, three to five months in a high-yield savings account, and maybe an additional two or three months in I-bonds building a longer-term buffer. Lucas: That's exactly what I do personally, actually. My emergency fund is split about twenty percent in checking — just for true immediate needs — and eighty percent in a high-yield savings account. I've also been slowly adding I-bonds each year, treating them as a second layer. They're not my primary fund, but they add a little extra security with inflation protection. Luna: I think that's a really practical framework. And it avoids the paralysis of trying to find the single perfect vehicle. You're diversifying the 'safe' bucket itself. Lucas: Yeah, I'd rather people do that than chase the highest yield by putting their emergency fund into something like a long-term bond fund or a dividend stock. That's not an emergency fund anymore — that's an investment. And if the market drops forty percent right when you lose your job, you're in real trouble. Luna: Let's talk about some real numbers for a minute. Say someone has a fifteen thousand dollar emergency fund. If they leave it in a checking account earning zero, they're losing about six hundred dollars a year in opportunity cost at current rates. That's a dinner out every month they're just giving up. Lucas: Yeah, and over five years, that's three thousand dollars — enough for a small vacation or a decent emergency appliance replacement. So there is a real cost to being lazy about this. Luna: On the flip side, if they chase yield too aggressively and pick something that isn't truly liquid or safe, the cost could be much higher. The point is to find the sweet spot. Lucas: Before we go further — a quick note. If today's episode was useful to you and you want to keep it ad-free, buy me a coffee dot com slash fexingo helps. That's literally what keeps these conversations going without any sponsor interruptions. Luna: Yeah, it's a small ask, but it makes a big difference for us. We really appreciate everyone who chips in. Lucas: So back to the sweet spot. I think for the vast majority of listeners, the answer is simple: open a high-yield savings account with an online bank that has a good app, good customer service, and a competitive rate. Move your fund there. Keep one month in checking. Done. Luna: What about people who have much larger emergency funds? Say someone has fifty thousand dollars because they're self-employed or have a very volatile income. That exceeds the FDIC limit if it's all in one account, right? Lucas: Good point. FDIC insurance covers up to two hundred fifty thousand per depositor per bank. So fifty thousand is fine in one account. But if someone has, say, three hundred thousand across multiple accounts at the same bank, only two fifty is insured. The fix is simple: spread it across two or three banks. Or use a money market fund at a brokerage, which isn't FDIC insured but is held in a separate account structure. Luna: Or use Treasury ETFs, which are backed by the government. But then you're back to the price-fluctuation issue. Lucas: Right. For very large cash reserves, I'd lean toward a combination: multiple high-yield savings accounts at different banks, plus some short-term Treasuries held directly — not through an ETF — to avoid the price risk. You can buy Treasury bills at auction through TreasuryDirect.gov or a brokerage, and they mature in four, eight, thirteen weeks. You can ladder them so some are maturing every few weeks. Luna: That's a more advanced strategy, but it's good to know it exists. For the typical listener, the key takeaway is: don't let your emergency fund rot in a zero-interest account. It takes thirty minutes to open a high-yield savings account online, and you can set up automatic transfers from your paycheck. Then it's done. Lucas: One last thing I want to mention: a common mistake is treating your emergency fund as one monolithic pile that never changes. But your life changes — your rent goes up, you get a raise, you have a kid. You should revisit the size of your fund at least once a year, and also check whether the vehicle you're using still has a competitive rate. The high-yield savings account that paid four point five percent last year might be paying two point five percent now if you didn't notice the rate change. Luna: Yeah, rate-chasing is a thing. Some banks offer teaser rates that drop after a few months. It's worth setting a calendar reminder every six months to check your rate and compare. Lucas: So to sum up: tier your fund, keep a month in checking for immediacy, put the bulk in a high-yield savings account, and consider I-bonds or short-term Treasuries for the portion you're less likely to tap. Don't overcomplicate it, but don't ignore it either. Luna: And whatever you do, don't invest it in the stock market. I've seen people do that and regret it deeply. Lucas: Yeah, that's a separate episode. We actually covered that a few episodes ago. But the short version: an emergency fund is insurance, not an investment. Keep it safe, keep it accessible, and give it a modest return. That's the whole strategy. Luna: I think that's a good place to leave it. Next time, maybe we can talk about how to rebuild an emergency fund after you've had to use it — because that's a real challenge for people. Lucas: Absolutely. That's a great topic. We'll see you next time on the Emergency Fund Podcast.
