Three things happened this week that look unrelated and aren't.
On Monday, the market was assigning better-than-even odds to the Federal Reserve raising rates in September rather than cutting them. On Wednesday, the July inflation report landed and everybody argued about a national average that describes almost nobody's actual costs. On Friday, retail sales showed a consumer that looks strong in aggregate and is quietly split into two populations, one spending portfolio gains and one drawing home equity lines at a floating rate.
The thread running through all three is a single question, and it's one I've never heard an individual investor ask about their own money.
Is this fixed, or does it float?
That distinction is the organizing principle of how banks are actually managed. It has a name, asset-liability management, and there are people whose entire careers consist of nothing else. Every institution that borrows and lends maps both sides of its balance sheet by when each item reprices, and then deliberately decides how much mismatch it wants to carry. A bank that gets this wrong doesn't lose money slowly through bad stock picks. It fails, sometimes in a weekend, and the failures of 2023 were a live demonstration of what happens when the asset side is locked long and the liability side reprices overnight.
Households have exactly the same structure. Assets on one side, liabilities on the other, each one repricing on some schedule or not at all. And virtually nobody has ever drawn the map.
Let me draw the distinction cleanly first, because the words get used loosely. A fixed-rate item has a rate contractually locked for a defined term. A thirty-year mortgage at 3.1 percent is fixed. A Treasury note you intend to hold to maturity is fixed. A floating-rate item resets off some benchmark, prime, SOFR, the effective fed funds rate, on a schedule you did not negotiate and cannot influence. A credit card balance floats. A home equity line floats. A money market fund floats. Your savings account floats, though the bank has discretion about how much of the move it passes through to you, which in practice means it floats up slowly and down quickly.
Two weeks ago I wrote about the spread between what your cash earns and what your debt costs, which is a question about the level of rates. This is a different question and in some ways a more important one, because it's about what happens when the level changes. You can have a perfectly sensible spread today and still be positioned catastrophically for the next move.
Four quadrants, and each behaves predictably.
Floating-rate liabilities are the ones that hurt you when rates rise. Card balances, home equity lines, business revolvers, variable-rate private student loans, adjustable mortgages past their fixed period. When the Fed moves, these reprice within a billing cycle or two. No notice that matters, no negotiation, no ability to opt out. This is the quadrant that turns a policy decision into a personal cash flow problem.
Floating-rate assets are the ones that help you when rates rise. Money market funds, savings, short Treasury bills as they roll, the front end of any cash ladder. These are the reason a lot of savers have quietly enjoyed the last three years without understanding why.
Fixed-rate liabilities are the quadrant almost everyone misreads. If you locked a mortgage in the threes during 2020 or 2021, that loan is not a burden in the current environment. It's an asset. You're borrowing money at a rate far below what the same money would cost today and far below what safe cash currently yields. Every time rates rise, the economic value of that contract to you increases, because you hold a below-market obligation that the lender cannot reprice. People pay these down early out of a general feeling that debt is bad, and in doing so they destroy one of the best positions on their balance sheet.
Fixed-rate assets are the quadrant that surprises people in the other direction. A long-dated bond pays exactly what it promised, which is wonderful if you hold it to maturity and painful if you have to look at the market value in the meantime. Rising rates knock down the price of an existing fixed-rate bond because newer bonds pay more. Nothing has gone wrong with the bond. You simply own a contract that's now below market, which is the mirror image of the low-rate mortgage, and if you're a forced seller you realize the loss for real.
Now do the arithmetic that institutions do and individuals don't. Add up your floating liabilities. Add up your floating assets. Whichever side is larger tells you your actual position with respect to interest rates.
If your floating assets exceed your floating liabilities, you benefit when rates rise. In the language of a trading desk, you're long rates. A household with a hundred thousand in cash and money market funds, a fixed mortgage at 3.4 percent, and no revolving balances is meaningfully long rates and is being paid to be. Most of the people in that position have no idea they're carrying a macro view, and it happens to be the correct one for the environment the market is now pricing.
If your floating liabilities exceed your floating assets, you're short rates, and every hike takes money directly out of your monthly cash flow. A household with twelve thousand on cards, an active home equity line, and three thousand in a checking account is short rates by a wide margin. Nobody in that position chose it. It accumulated, one decision at a time, each of which made sense in isolation.
That's the whole insight, and it's worth stating plainly. Almost every household in America is carrying a substantial, unhedged bet on the direction of interest rates. Almost none of them placed it deliberately, and almost none of them could tell you which way it points.
Before you go build the map, four complications that determine whether the exercise is accurate or merely comforting.
First, most things labeled fixed are only fixed until a date. An adjustable mortgage in its fixed period, a home equity line with a promotional rate, a business term loan with a five-year reset or balloon, a certificate of deposit maturing next spring. Each of these is floating with a delay, and the delay is the only thing separating you from the exposure. So the map needs two columns, not one: fixed or floating, and then the date on which that answer changes. An item fixed for eleven more months belongs in a very different mental bucket from one fixed for twenty-two more years.
Second, bond funds are not bonds. An individual bond held to maturity returns your principal on a known date regardless of what happens in between. A bond fund is a perpetually rolling portfolio with no maturity date, which means the price risk never rolls off. Both can be entirely appropriate. They are not substitutes, and the difference matters enormously for money you'll need on a specific date.
Third, and this is the one people never include: your income is a floating-rate asset. It reprices with the labor market, on a schedule set by your employer or your customers, in an environment where hiring has slowed noticeably and revisions have been running negative. Worse, it tends to reprice downward at exactly the moment your floating liabilities are repricing upward, because the Fed usually stops hiking only after something in the labor market breaks. Correlation between your assets and liabilities is what makes a mismatch dangerous rather than merely uncomfortable, and this is the correlation nobody models.
Fourth, inflation-protected securities float in real terms rather than nominal ones, which makes them a genuinely different instrument from everything else on the list. Their principal adjusts with the consumer price index, so they hedge the exposure most households actually have, which is to purchasing power rather than to a policy rate. Pair one against a fixed low-rate mortgage and you're holding a real spread trade that a pension fund would recognize immediately.
The exercise itself is straightforward. List every asset and every liability. Mark each fixed or floating. For anything fixed, note the date the answer changes. For anything floating, note the benchmark and how often it resets. That's it. It takes about forty minutes, and the reason so few people have one is that the underlying information is scattered across a mortgage servicer, two banks, a brokerage, a card issuer, and a loan portal nobody has logged into since the terms were signed. Pulling all of it into a single view with a tool like Empower is what makes the difference between a map you actually finish and a project you describe to yourself for three years.
Once you can see the position, changing it is mostly about exercising options while they're still cheap.
If you're short rates and don't want to be, the moves are to convert floating liabilities to fixed where a fixed option exists, to attack the floating balances that carry the worst rates first, and to build the cash buffer that keeps a bad month from generating new floating debt. Every one of those works whether or not the September meeting produces a hike, which is exactly the property you want in a decision made under uncertainty.
If you're long rates, the discipline is different and it's mostly about not accidentally giving the position away. Don't pay off a three percent mortgage to feel tidy. Don't stretch reserve cash out the curve chasing an extra twenty basis points and lose the flexibility that made the position valuable. And recognize that being long rates means you're implicitly short a cutting cycle, so if the labor market does crack and cuts arrive, your cash yield falls at the same time everything else gets harder. Matching maturities to the dates you actually need money, rather than optimizing yield in the abstract, is what protects against that.
For anyone running a business, the same map applies and the stakes tend to be higher because the balances are larger. Your revolver floats. A term loan probably doesn't. Your customer contracts are fixed price unless you wrote an escalator into them, while your input costs float with producer prices that have been running well above consumer inflation. That combination, floating costs against fixed revenue, is the single most common way a profitable small business becomes an unprofitable one without anything visibly going wrong. The two structural fixes are indexation clauses on the revenue side and a lower fixed cost base on the operating side, and on the second one, moving recurring manual work onto an automation platform like Make reduces the cost base permanently rather than for a quarter.
The last piece is the one that determines whether any of this survives. A map drawn once and filed away is worth almost nothing by the time the reset dates you noted actually arrive. What makes it durable is putting the recurring pieces on rails: contributions on a schedule, allocations rebalanced on rules, reset dates on a calendar with a reminder attached. Running the allocation layer through a platform like M1 Finance means the structure keeps executing during the quarters when you're not thinking about it, and those are the quarters that decide outcomes.
The calendar from here is straightforward. The minutes from the July meeting come out Wednesday, and given that three officials dissented in favor of a hike, the discussion behind that vote is worth more than usual. The Jackson Hole symposium runs August 27 through 29, with this year's program built around financial innovation and payments, and the Chair's remarks there have historically been the venue where direction gets signaled ahead of a decision. Then the meeting itself on September 16.
None of which you need to predict. That's the entire point of the map. Once you know which way your balance sheet points and by how much, the Fed's decision stops being a source of anxiety and becomes a piece of information with a known effect on a position you chose on purpose.
I built the map as a two-page template: the four quadrants with prompts for what belongs in each, the reset date column, a worksheet that nets your floating assets against your floating liabilities so you can see your actual position in a single number, and the specific moves available on each side depending on which direction that number points. Reply with the word FLOATING and I'll send you The Fixed vs Floating Map. Forty minutes, and you'll know something about your finances that most people with a financial advisor still don't.
If this is the kind of thinking you want more of, the best support you can give the work is to pass it to one person who'd use it.

Every balance sheet is a bet on interest rates. The only question is whether you know which one you made.
