Latest / The Emergency Fund Podcast with Fexingo: Cash Reserves, Saving, and Financial Cushion / How Your Emergency Fund Can Also Fight Inflation
Transcript
- Lucas: So, we've spent nine episodes talking about emergency funds — how much to set aside, where to keep it, how to rebuild it after you've drawn it down. But there's a tension we haven't really unpacked. Luna: The inflation tension, right? That cash you're holding safe and sound is quietly losing value. Lucas: Exactly. A dollar in your emergency fund today buys maybe four percent less than it did a year ago. Over three years, that compounds. So the question is: can your emergency fund also fight inflation — without sacrificing the safety and accessibility that makes it an emergency fund? Luna: I've seen people online suggest TIPS, or just dumping it all into the stock market. Both feel like the wrong answer. Lucas: Right. TIPS are inflation-protected but they're bonds with price volatility if you sell early. Equities are great long term but terrible if you need the money during a downturn. So there's a middle-ground tool that gets surprisingly little attention for this specific use case: Series I Savings Bonds. Luna: I Bonds. I've heard about them but I don't think I've ever seriously considered them for an emergency fund. Lucas: Most people don't. And for good reason — they have a one-year lockup, you can't redeem at all in the first twelve months. After that, there's a three-month interest penalty if you cash out before five years. So they're not a pure substitute for a high-yield savings account. Luna: So you're saying use I Bonds for a portion of the emergency fund, not the whole thing. Lucas: Exactly. Think of a tiered approach. The first two or three months of expenses sit in a high-yield savings account — instantly accessible, no strings attached. Then the next three to six months go into I Bonds. They earn a composite rate that's reset every six months based on inflation, so your purchasing power is preserved. Luna: And what's that rate looking like now? May 2026 — we're not in the crazy inflation we had a couple years ago, but prices are still climbing. Lucas: The latest composite rate for I Bonds issued through April 2026 is about 4.8 percent. Compare that to the best high-yield savings accounts, which are hovering around 4.5 percent. Not a massive difference, but over a few years it adds up. More importantly, the I Bond rate adjusts with inflation. If inflation spikes again, your yield follows. The savings account rate might lag or get cut. Luna: So there's a built-in hedge. But the one-year lockup is the big concern for most people. What if you have an emergency in month eleven? Lucas: That's why you never put your entire emergency fund into I Bonds. You keep that first tier — the quick-access layer — big enough to cover any realistic near-term need. The I Bond layer is for the portion you're less likely to tap immediately. If you have fifteen thousand dollars saved, maybe five thousand stays in savings and ten thousand goes into I Bonds over time. Luna: And you'd buy them gradually, right? There's an annual purchase limit. Lucas: Right now it's ten thousand dollars per person per year, plus you can use your tax refund to buy another five thousand. So for an individual, you could build up a meaningful position in one year. For a couple, double that. The limit actually encourages disciplined, gradual accumulation — which fits nicely with how you should build an emergency fund anyway. Luna: I like that. It forces you to think of the emergency fund as a process, not a one-time thing. Lucas: And the interest is state-tax-free, which is a bonus if you live in a high-tax state. Federal taxes apply, but only when you redeem. So it's tax-deferred growth until you need the money. Luna: Speaking of money and the show — you know, we keep this podcast ad-free, and that's a choice we've stuck with. A couple of dollars a month is genuinely what keeps these going. If you've gotten something out of our episodes, there's a link at buy me a coffee dot com slash fexingo. Lucas: Yeah, it's a small thing that makes a real difference. No pressure, but if you find the conversations useful, that's the easiest way to help us keep them going. Back to the I Bond strategy — one more nuance: the three-month interest penalty if you redeem before five years. Luna: Right, so it's not a penalty in the traditional sense. You just forfeit the last three months of interest. Lucas: Exactly. So if you hold for, say, two years and need to cash out, you lose three months of interest but you still earned twenty-one months of inflation-adjusted yield. That's still better than a savings account over the same period, especially if rates drop. And if you hold for five years, no penalty at all. Luna: So the ideal hold time is at least five years. But emergencies happen before that. It's still a good deal. Lucas: Right. And you can structure it so the I Bond portion matures into the penalty-free window gradually. Buy some this year, some next year — after five years, you have a rolling ladder where some bonds are always penalty-free. Luna: That's a nice strategy. It's almost like a CD ladder but with inflation protection. Lucas: Exactly. And unlike a CD, I Bonds can't lose principal. The composite rate can be zero or very low if there's deflation, but the bond never drops below its face value. So the nominal value is always protected. Luna: So let's say I'm a listener with a fifteen thousand dollar emergency fund. What would the concrete allocation look like? Lucas: Five thousand in a high-yield savings account — that's about two months of basic expenses for a typical single person. Then ten thousand in I Bonds, bought over the course of a year. That gives you twelve months of expenses total, with the bulk earning an inflation-adjusted yield. The savings account covers the first month of any emergency, and by the time you'd need the I Bond money, the one-year lockup is behind you. Luna: But what if the emergency is bigger than five thousand? A medical bill or car repair could eat that up fast. Lucas: Good point. That's where the credit card float comes in. You can put the expense on a card, then redeem I Bonds — the TreasuryDirect transfer takes a couple of business days — and pay off the card before interest accrues. So the effective access is about three to five days, not instant but fast enough for most non-catastrophic emergencies. Luna: That's smart. It makes the liquidity concern less scary. Lucas: And if you have a true catastrophe — natural disaster, job loss, medical crisis — you probably have a few days before you need to pay. The credit card bridge works. Luna: Let's talk about the mechanics. How do you actually buy I Bonds? Lucas: You need a TreasuryDirect account — it's a government website, not the most modern user interface, but it's functional. You link your bank account, then you can buy up to ten thousand dollars per calendar year. The bonds are issued electronically. You can also buy paper I Bonds with your tax refund, but that's a separate process. Luna: Is there any risk that the government changes the rules? I know there's been talk about lowering the purchase limit or altering the rate structure. Lucas: The Treasury has adjusted the fixed rate component in the past. In 2022, when inflation was high, they raised the fixed rate to encourage purchases. They could lower it too. But the inflation adjustment is formulaic — it's tied to the Consumer Price Index. That part is set by law. So even if the fixed rate goes to zero, you still get the inflation component. Luna: So the worst case is you earn zero real return, but you don't lose purchasing power. That's basically what a savings account gives you in a low-rate environment. Lucas: Exactly. And in a high-rate environment, you do better. So it's asymmetric upside. That's the key appeal. Luna: I'm sold on the concept. But there's one thing that gives me pause: the account management. TreasuryDirect isn't exactly user-friendly, and if you lose your password or your two-factor device, it's a nightmare to get back in. Lucas: That's a real concern. The customer service is notoriously slow. My advice: keep meticulous records. Save your confirmation numbers, write down your password in a secure place — a password manager, not a sticky note — and set up a secondary contact method. Also, consider buying in smaller increments so you're not putting all your eggs in one basket. Luna: Or you could use a brokerage that offers I Bond ETFs, though I don't think those exist yet. Lucas: They don't. I Bonds are only available directly from TreasuryDirect, or in paper form via tax refund. So you have to deal with the interface. But for most people, the initial setup takes thirty minutes, and then you buy once a year. It's not a daily chore. Luna: Fair. And the payoff is a more resilient emergency fund that doesn't get eaten by inflation. I think the tiered approach is the most practical takeaway from this episode. Lucas: I agree. The big idea isn't to replace your emergency fund with I Bonds. It's to use them as a complement — a way to give the portion you're least likely to touch a fighting chance against rising prices. The rest stays liquid and safe. Luna: And for listeners who already have a fully funded emergency fund in a savings account, it's worth considering a gradual shift. Sell some of the savings, buy I Bonds, and rebuild the savings over time. Lucas: Right. The key word is gradual. You don't want to lock up money you might need next week. But if you have a stable job and a solid cushion, moving a portion into I Bonds over six to twelve months is a low-risk way to inflation-proof your safety net. Luna: Let's leave listeners with a concrete next step. If someone wants to start, what's the first thing they should do? Lucas: First, figure out your emergency fund target — three months, six months, whatever works for your situation. Then decide what portion you're comfortable having less liquid. Maybe it's twenty percent, maybe it's fifty. Then open a TreasuryDirect account, and buy your first I Bond. Set a reminder to buy again next January. That's it. Luna: And check the current composite rate before you buy. It changes every May and November. Lucas: Good point. As of today, May 25, 2026, the rate is roughly 4.8 percent. That's decent. But even if it were lower, the inflation protection is the real value. Thanks for listening, everyone — hope this gives you a new tool for your financial toolkit. Luna: See you next time.
