There's a number almost nobody checks, and it's costing regular people more than any market crash ever has.
It's the yield on their cash.
Right now, as you read this, the Federal Reserve has its benchmark rate sitting at 3.50% to 3.75%. That's where it's been for four straight meetings in 2026, after three cuts late last year. New Chair Kevin Warsh and the committee held again in June, and they'll meet next on the 28th and 29th of this month. The market spends enormous energy guessing what they'll do next. Almost nobody spends any energy on what that rate already means for the cash they're holding today.
So let me make it concrete. The FDIC puts the national average savings rate at about 0.38%. The three largest banks in the country, the ones where most people actually keep their money, pay 0.01% on a standard savings account. Meanwhile, the best high yield savings accounts and money market funds are paying somewhere between 4.00% and 4.50%. You can confirm that yourself in any current rate survey from Bankrate.
Sit with the size of that gap for a second, because it's not a rounding error. On $25,000 of cash, the difference between 0.38% and 4.25% is roughly $965 a year. Every year. On $50,000, it's close to $1,930. That money isn't lost to a risky bet or a bad market. It's handed to your bank, quietly, because you never made a decision. And here's the part that should sting a little: your bank is earning that spread on your deposits and paying you almost none of it back. The system is doing exactly what it was built to do. It's just not built for you.
This is the difference between how institutions think about cash and how most people think about it. To a household, cash is the money that isn't invested yet, the leftover, the thing sitting in the account until it becomes something else. To an institution, cash is a position. It's an asset class with its own job, its own yield target, and its own risk profile. A treasury desk at a fund would be fired for leaving millions in an account earning 0.01% while risk free instruments pay north of 4%. Yet everyday savers do the equivalent every single day and never think twice, because nobody ever framed idle cash as a decision they were actively making.
Let's fix the framing, because the fix is genuinely simple and it doesn't require you to take on any more risk than you already have.
Start by separating your cash into tiers based on when you'll actually need it. This is what a treasury operation does, and it's the single most useful mental model I can give you. You have three buckets. The first is your operating cash, the money that pays this month's bills and covers the small surprises. It needs to be instantly available and you shouldn't obsess over its yield, because its job is access, not return. Keep it lean. Most people keep far too much here out of habit.
The second tier is your reserve, your emergency fund, the three to six months of expenses that exist to keep a bad month from becoming a catastrophe. This money needs to be safe and reachable within a day or two, but it does not need to sit in your checking account earning nothing. This is the tier where the 0.38% versus 4.25% gap does the most damage, because it's usually the largest pile of cash a household holds, and it's the pile people are most afraid to touch, so it sits still for years. A high yield savings account or a money market fund at a reputable institution is purpose built for exactly this. It's liquid, it's insured up to $250,000 per institution when you use an FDIC member bank, and it pays you something real for the privilege of holding your money.
The third tier is cash you know you won't need for a defined stretch, six months, a year, longer. This is where you can reach for a certificate of deposit and lock in a fixed rate, which matters more than usual right now. Here's why. For most of the last two years, the assumption was that the Fed would keep cutting and cash yields would drift lower, so locking in didn't feel urgent. That assumption has quietly shifted. The committee has held four times, cited persistent inflation, and some forecasters now think the next move could actually be a hike rather than a cut. Nobody knows. But when the direction of rates is genuinely uncertain, locking in a known 4% on money you won't touch for a year is a decision you can make with a clear head, not a gamble.
Notice what we did there. We didn't predict the Fed. We didn't try to time anything. We just matched each pile of cash to the right instrument based on when we'd need it, and in doing so we captured yield that was sitting on the table the whole time. That's the institutional move. It's boring, it's mechanical, and it's worth more than most of the clever things people do with the money they're actually trying to grow.
The reason so few people do this isn't ignorance. It's friction and inertia. Opening a new account feels like a chore. Moving money feels like a risk even when it isn't. And the loss is invisible, because you never see the interest you didn't earn. A market drop shows up as a red number that makes you flinch. A cash drag of a thousand dollars a year shows up as nothing at all. It just doesn't happen. This is why the wealthy have always been better at this than everyone else, not because they're smarter, but because they, or the people they pay, treat every dollar as if it has a job, and they check whether it's doing that job.
There's a second, quieter cost stacked on top of the yield you're missing, and it's inflation. Even with price growth cooling from its peaks, it hasn't gone away, and the Fed itself keeps naming it as the reason rates are staying high. Inflation is a tax on idle money that nobody ever sends you a bill for. If your cash earns 0.38% while prices rise faster than that, your money loses purchasing power every single month it sits still, slowly, invisibly, and guaranteed. The cruel twist is that the choice that feels safest, leaving everything in the big bank account you've always used, is the one quietly draining you. Safety from market swings is not the same thing as safety from erosion, and people confuse the two constantly. An account paying above 4% doesn't just earn you more. It's the line between staying ahead of inflation and falling behind it while feeling responsible about it.
Let me put real numbers on the tiering, because abstractions don't move anyone to act. Say you're holding $40,000 in cash, which is ordinary for a household with a decent emergency fund. Right now it's probably all sitting in one account earning close to nothing. Here's the operator version. You decide $5,000 covers this month and the small surprises, so it stays in checking where you can reach it instantly, and you don't fuss over its yield. The next $25,000 is your reserve, roughly six months of expenses, and it moves to a high yield savings account or money market fund earning around 4.25%. The remaining $10,000 you know you won't touch for at least a year, so it goes into a one year certificate of deposit locking in a fixed rate near 4%. You've taken on zero additional market risk. Every dollar is still safe, still insured, still yours. But instead of earning a handful of dollars a year, that same $40,000 now earns well over $1,400. Same money, same safety, one afternoon of work, and the gap compounds for as long as you keep the discipline.
You can build that same discipline without hiring anyone. The first step is simply seeing all of it in one place. Most people have no unified picture of where their cash actually lives, how much of it is earning nothing, and how it fits against everything else they own. A free tool like Empower lets you connect your accounts and see your full financial picture on one dashboard, cash included, so the idle money stops hiding. You can't fix a leak you can't see, and for most households the cash drag is the biggest invisible leak they have.
The second step is putting the reserve and the medium term cash somewhere that actually pays. If you want your cash and your investing to live under one roof, M1 Finance offers a high yield cash account alongside automated investing, which makes it easier to keep the whole system in one place and move money between saving and investing without the usual friction. The specific institution matters less than the act of moving. Whatever you choose, the rule is the same: no tier of your cash should be earning a rate that starts with a zero unless it's the small operating pile you need instant access to.
Let me push on one more thing, because it's the objection I hear most. People say the difference isn't worth the hassle. A thousand dollars, they say, isn't going to change their life. And on its own, in one year, maybe not. But this is compounding we're talking about, and compounding is unforgiving in both directions. That thousand dollars a year, captured and reinvested over a decade, is not a thousand dollars. It's the seed of a meaningful position. More importantly, the habit of asking whether every dollar is doing its job is the exact habit that separates people who build wealth from people who merely earn income. It's not the single decision. It's what the decision trains you to do.
Here's what I want you to actually do this week, before the Fed meets and the headlines start telling you to feel something about a number you don't control. Pull up every account that holds cash. Write down the balance and the actual yield next to each one. Not the yield you think you're getting, the real one, which for most big bank savings accounts will be a decimal so small it's almost funny. Then sort that cash into the three tiers. Operating, reserve, and locked. Move the reserve and locked money to instruments that pay. You can finish the whole exercise in under an hour, and it will very likely be the highest paid hour of your month.
The Fed's decision on the 29th will get wall to wall coverage. Whatever they do, it changes your cash strategy far less than the decision you can make today, which is to simply stop leaving free money on the table. Rates this high on safe cash are not permanent. We've had years of near zero in recent memory, and we'll likely have them again. The window to earn 4% on money that carries no market risk is open right now, and windows close.
If you want the exact framework I use to sort and place cash, I put together a one page worksheet that walks through the three tiers, the yield targets for each, and a short checklist for choosing where to park the reserve. It's called the Cash Command Sheet, and it's the fastest way I know to stop the leak. Reply to this email with the word CASH and I'll send it straight to you, no charge.
