Latest / Inflation and Your Money with Fexingo: Protecting Purchasing Power and Beating Inflation / How Inflation Is Quietly Eating Your Mattress Money
Transcript
- Lucas: So Luna, I was talking to a friend last week who swears by keeping a few thousand dollars in a shoebox under his bed. And I get the comfort factor, I really do. But with inflation running at two point three percent, that shoebox is quietly costing him real money. Luna: You mean because the cash just sits there while prices go up? Yeah, it's like the mattress is a slow-motion shredder for purchasing power. Lucas: Exactly. And it's not just the shoebox crowd. Even people with money in a regular checking account are losing out. The latest CPI reading — July's, at three hundred thirty-two point eight — shows prices still creeping up, even if the pace has slowed. Core PCE, the Fed's favorite gauge, is up too. Luna: So what's the real number? How much does, say, ten thousand dollars in cash lose in a year? Lucas: If inflation is two point three percent, that's two hundred thirty dollars in purchasing power gone every year, assuming zero interest. But here's the rub — most checking accounts pay next to nothing. Even a high-yield savings account might give you three point five percent right now, so you can actually beat inflation. But if you're earning zero, you're losing two point three percent a year, guaranteed. Luna: And that's before you even think about opportunity cost. That ten grand could be in the S&P 500, which, even after last week's dip, is still up strong over the past year. Lucas: Right, but we're not telling people to put their emergency fund in equities. The point is, there's a spectrum. Cash under the mattress is at the bottom — zero return, negative real return. A high-yield savings account is step one. Then short-term Treasuries, or even a money market fund. Each step up the ladder gives you a little more yield, but you trade off some liquidity or safety. Luna: So what's the rule of thumb? How much should people even keep in cash? Lucas: Most advisors would say three to six months of expenses in an emergency fund. Beyond that, cash starts to become a drag. And I think a lot of people don't realize how much of their portfolio might be sitting in cash-like instruments without them even thinking about it. Luna: Like in brokerage accounts, sitting in the default sweep. That's been a theme on this show — bank sweep accounts, right? Lucas: Yeah, and that's a whole episode we've done. But today I want to focus on the psychological side. Why do people hold so much cash when inflation is eating it? It's fear, it's habit, it's simplicity. And I think we can give people some practical ways to think about it without getting preachy. Luna: Well, and before we get into solutions, we should give a quick shout-out to the listeners who make this possible. A handful of folks chip in monthly through buy me a coffee dot com slash fexingo, and honestly, that's what funds us making this many episodes a week. No ads, no sponsors — just listener support. Lucas: It's true. And we don't say that often enough. If you've ever gotten something useful out of these conversations, that support is what keeps it going. But back to the math — because I think the real eye-opener is how long it takes for inflation to really gut your cash. Luna: Yeah, let's do the rule of seventy-two. At two point three percent inflation, it takes about thirty-one years for your money to halve in value. That sounds slow, but for a thirty-year-old saving for retirement, that's a lifetime. Lucas: Exactly. And if inflation runs hotter, say four percent, that halving happens in eighteen years. The point is, time is the multiplier. The longer you hold cash, the worse the damage. And that's why even a small shift — moving from a checking account to a high-yield savings account — can make a real difference over a decade. Luna: So what's your practical advice? For someone who's got, I don't know, twenty grand sitting in a zero-interest checking account? Lucas: First, figure out your true emergency number — three to six months of expenses. That's your floor. Then, shop around. The average high-yield savings account is paying close to four percent right now. That's a huge jump from the zero point zero one percent you might be getting. Just that one move, on twenty thousand dollars, is roughly eight hundred bucks a year in extra interest — and it keeps you ahead of inflation. Luna: And if they've got more than that, maybe start a small ladder of Treasury bills or I bonds. I bonds are indexed to inflation, so they're a natural fit for this conversation. Lucas: Good point. I bonds have a fixed rate plus an inflation adjustment, so they're designed to protect purchasing power. But there are limits — ten thousand dollars a year per person. So it's not a parking spot for a windfall, but it's a solid 'second bucket' for cash beyond your emergency fund. Luna: And what about the psychological comfort of having cash at hand? I mean, there's something to be said for that. Lucas: Absolutely. I'm not saying nobody should have cash. In fact, I think a small amount of cash — maybe a few hundred — is smart for emergencies. But beyond that, you're paying a premium for comfort. And the data shows that premium can be steep. Over the last twenty years, cash has lost about thirty percent of its purchasing power. That's not nothing. Luna: So when you look at the current environment — inflation cooling but still positive, gold at four thousand seven hundred eighteen an ounce, up five percent this week alone — what's the takeaway for our listeners? Lucas: The takeaway is: don't let cash be a default. It should be a conscious choice — and if you're going to hold it, at least make it work for you. You don't have to beat inflation by a mile, but you shouldn't be handing it a victory by keeping money in a zero-yield account. Luna: That's a good line. So bottom line: review your cash, park it in something that pays, and don't fear the high-yield savings account. It's not rocket science. Lucas: Exactly. And if you're not sure where to start, just look at your biggest account balances. The ones that are earning next to nothing are the ones to move. It's a five-minute task that could pay you hundreds of dollars a year. Luna: We should also note that inflation data can be revised, so the numbers we're quoting today might shift slightly. But the direction is clear. Lucas: Right, the July CPI came in at three hundred thirty-two point eight, up from three hundred thirty-two point five seven. Core, ex food and energy, was three hundred thirty-six point eight. So the trend is up, even if it's modest. And PCE actually dipped slightly, but that's an older data point. The point stands — prices are still rising. Luna: And with the Fed funds rate at three point six three percent, there's still a decent gap between what banks pay and what they could pay. So shopping around matters. Lucas: For sure. And one last thing: don't forget to factor in taxes. The interest you earn on a high-yield savings account is taxable, so your after-tax return is what really matters. If you're in a high tax bracket, a tax-exempt municipal money market might be worth a look. Luna: Great point. So, to sum up: mattress money is a losing game, high-yield savings is the easy fix, and a little planning can keep your purchasing power intact. Lucas: And if you want to dig deeper into your own numbers, we've got resources on the show page. But for now, that's a wrap on the shoebox problem. Thanks for listening, everyone.
