It’s simple. When interest rates rise, bond prices fall. Stocks get nervous. Yields go up. Good for retirees? Maybe, or maybe not. Any questions?
Interest rates have been in the news for a while now, which is a polite way of saying they have become a regular and mostly unwelcome topic, showing up in headlines and also in small talk about “the Fed” over coffee or at a dinner party. You’ve probably heard economic terms tossed around with casual confidence by people who may or may not know what they mean. Or claims like “a return to super low interest rates would be the best thing for our economy.”
(Very low rates help some parts of the economy and hurt others; they’re not an unambiguous good. The reality is that the right interest rate depends on where the economy is; too high chokes growth and borrowing, too low distorts markets and diminishes returns for savers. “The Fed” typically aims for something closer to “neutral,” not “lowest possible.” The opposite of this is, “Rising rates are always bad.” Rate hikes get blamed for slowdowns, but they’re often a response to an overheating economy or inflation that would do more damage left unchecked.)
Politicians, in particular, despite their best efforts, make bad economists. Many (perhaps, most) wouldn’t know the difference between the Fed funds rate and the discount rate—though they’ll gladly hold a press conference and opine about whichever one just happened, using the tone of someone who understands completely but who’s only just read the briefing memo. But ask one to explain the inverted yield curve, and you’ll get three minutes of confident eye contact and a lot of words with zero actual content, or what is sometimes called a “word salad,” which is itself a kind of monetary policy. The real tell is that they only ever seem to have opinions about rates in one direction: down, always down, preferably yesterday, preferably near zero. That’s because nobody has ever lost an election promising cheaper money. It’s the fiscal equivalent of promising better weather—it sounds good on TV, everyone’s for it, nobody’s in charge of delivering it (except God), and when it doesn’t happen, there’s always someone else to blame—usually “the Fed” or the other party.
As an aside, if you’re in a conversation with someone and they use the phrase “a few basis points” and you find yourself nodding along while secretly wondering what in the world a basis point is, you’re in good company.1 The good news is that none of this requires an economics degree, a Bloomberg terminal, or the ability to explain quantitative easing at a party without everyone slowly backing away. It just requires a little patience, a working sense of how rates and retirement actually connect, and—if we’re being honest—the occasional willingness to admit that “it’s simple” doesn’t quite do it justice.
If you’re still reading, you are either genuinely curious about how interest rates work (who wouldn’t be) or you’re married to someone who explains things the way Earl does and has learned to just let them talk. Either way, as it turns out, it’s not actually that simple, or at least not as simple as it sounds when someone leads with those two words at the dinner table. You may come away from the conversation confused and perhaps with some indigestion.
When someone begins a difficult explanation with the words, “It’s simple…,” or “it’s simple math,” brace yourself. Sometimes it really is a genuine attempt to simplify a complex topic—a kindness, even, from someone who’s done the hard work of understanding so you don’t have to. But just as often, “it’s simple” is the sound of a person talking themselves through a topic in real time, like a pilot announcing an emergency landing procedure and asking you to stay calm when they’re as nervous as everyone else. What follows is rarely simple. It usually involves at least three tangents, and ends by circling back to “so basically it’s…” for the fourth time. They didn’t understand it very well, and now neither do you, but at least you may have added to your economic vocabulary.
Still, Earl’s “simple” explanation is pretty good, even though it probably packed more than Dot needed, and the issues are much more nuanced than he gives them credit. Economics is a strange field. An economist is someone who, when you ask them how their day was, says, “It depends.” It always just depends. Dot thinks his explanation is a lot like their conversations early in their marriage when Earl was in his Amway phase.
Here’s what’s actually true: interest rates and bond prices do move in opposite directions. For most of us, that’s all you really need to know. But if you want to dig deeper, here you go: This is called an “inverse relationship,” and the economics of it work like this: When rates rise, newly issued bonds start paying higher yields. That makes your existing lower-yielding bonds less attractive to other investors, so their market price drops to compensate. Nobody wants yesterday’s yield at today’s prices; it’s the same reason last year’s iPhone is less costly the week after the new one comes out. Meanwhile, stocks tend to wobble during rate-hiking cycles because higher borrowing costs squeeze corporate profits and make investors nervous. So, a rising rate environment can feel like everything is going down simultaneously, while the one thing going up is the rate itself. Which is technically true. And it’s not the whole story, either.
Here’s the genuinely good news for retirees, buried under all the other moving parts: when rates rise, yields rise with them. Savings accounts, money market funds, certificates of deposit, and newly issued Treasury bonds all start paying meaningfully more. After more than a decade of near-zero interest rates that left conservative savers earning nothing on their cash holdings, essentially, the rate environment that emerged in 2022 and 2023 was, other than the short-term turbulence, genuinely the best news income-focused retirees had seen in years. A 4% to 5% yield on a Treasury bill or CD is not nothing. For a retiree drawing income from a portfolio, it is meaningful, reliable (at least in the short term), and real. That part is actually fairly simple: for many retirees, higher interest rates = good; lower interest rates = bad. And the reverse is true for young borrowers, like homebuyers who need a mortgage.
The catch—and there is always a catch, which is why it was never quite as simple as advertised—is that rising rates rarely occur for no reason. They tend to show up alongside inflation, which means your 5% yield is quietly competing with groceries that cost significantly more than they did three years ago, insurance premiums that have crept steadily upward like they’re training for something, and a general cost of living that doesn’t always align with what the politicians say. It’s why you may think twice about buying one of those Slim-Jims next to the tabloids in the check-out line at the grocery store, when 2 bags of food cost over $100. (Still, who doesn’t love a good Slim Jim? You can get one that’s almost 3 feet long.)
The Bible doesn’t talk about inflation in modern monetary terms, obviously; there’s no Fed, no CPI, no economists arguing on cable news, but it has quite a bit to say about the underlying issues: the erosion of value, the temptation to cheat measurement, and the anxiety of not having enough. Proverbs returns to this theme often: For example, “Unequal weights and unequal measures are both alike an abomination to the LORD (Proverbs 20:10). Merchants in the ancient world would keep two sets of weights, a heavier one for buying and a lighter one for selling, quietly debasing every transaction. That’s basically ancient inflation by criminal fraud rather than policy; the coin didn’t lose value, the scale just lied about it. It seems as though every generation finds a new way to shrink the dollar in your pocket without technically touching the dollar.
Which is why the wisest response to any interest-rate environment is to understand the whole picture—rates, yields, inflation, the sequence of returns, income needs—and to build a retirement income strategy that accounts for all those moving parts (and move they will, usually right when you’ve finally gotten comfortable).
Earl was trying to be reassuring, which is a good thing, but “simple” was probably not the best opening. Earl keeps starting there anyway, which is either an endearing habit or an optimistic one, depending on which side of the kitchen table you’re sitting on. Dot has her own word to describe it. The only thing Tippy cares about is his food bowl. Some things, it turns out, are exactly as complicated as they seem, and the first step toward handling them wisely is resisting the urge to oversimplify them, however tempting that particular shortcut may be.
[1] According to Investopedia, “A basis point (BPS) is a way to show changes in interest rates or yields. One basis point equals one-hundredth of a percentage point, making it a precise way to discuss even very small rate movements. Basis points are typically expressed with the abbreviations “bp,” “bps,” or “bips.” One basis point is equal to 1/100th of 1%, or 0.01%. In decimal form, one basis point appears as 0.0001 (0.01/100).”
