The Fed Cut 1.75%. Mortgage Rates Went Up. Here's the Part Nobody Explains.

A hundred and twenty central bankers head to Wyoming next week. Here's what that meeting actually does to your mortgage rate — and an honest look at the math on waiting, in both directions.

I get this question about four times a week, and it's a completely fair one:

"Should we wait for the Fed to cut rates before we list?"

It sounds reasonable. It sounds patient. It's the same instinct that tells you not to buy the first car on the lot.

But there's a mechanical detail underneath it that almost nobody explains properly, and once you see it, the whole question changes shape. So let's walk through it — the numbers, the history, and the honest case on both sides.

Start with the number that surprises everyone

The Federal Reserve's benchmark rate peaked at 5.25%–5.50%.

Today it sits at 3.50%–3.75%, where the committee left it at its July 29 meeting.

That's 175 basis points of cuts — a full point and three quarters, delivered over roughly two years.

And the average 30-year fixed mortgage today? 6.67%, per Freddie Mac's August 13 reading. Daily lender surveys had it nearer 6.73% earlier this week.

A year ago it was 6.58%.

So: the Fed cut 175 basis points. The 30-year mortgage went up about nine.

That's not a typo, and it's not a scandal. It's just how the plumbing works — and it's the single most useful thing a Chicago buyer or seller can understand right now.

It is, admittedly, a very Chicago outcome. Looked like a gift. Tasted like Malört.

The Fed doesn't set your mortgage rate. It never has.

This is the part the headlines flatten.

The federal funds rate is what banks charge each other for overnight loans. Overnight. Borrowed at dinner, returned before the coffee's done.

It has roughly the same relationship to your 30-year mortgage that the Kennedy at 3 a.m. has to the Kennedy at 5 p.m. Technically the same road. Very different experience.

Your mortgage rate tracks the 10-year Treasury yield, plus a spread that historically runs about 1.7 to 2.25 percentage points.

Think of it this way: the Fed influences the short end. The bond market prices the long end. Your mortgage lives on the long end.

So where's the 10-year sitting?

It touched 4.75% on Tuesday — its highest level in 20 months. It eased back toward 4.7% Wednesday. The 30-year Treasury recently reached a 19-year high.

Bond investors are asking for more yield right now for a few reasons at once: inflation that hasn't fully settled, energy prices, heavy government borrowing, and an enormous wave of corporate debt issuance — AI companies alone are projected to issue up to $1.5 trillion this year. When the market is flooded with bonds, buyers get choosier, and choosier means higher yields.

Now do the arithmetic. Take 4.7%, add a normal spread, and you land right around 6.5% to 6.9%.

Your mortgage rate isn't broken. It's tracking its actual benchmark almost exactly.

We've already run this experiment. Twice. In public.

If that sounds theoretical, here's the record.

September 18, 2024. The Fed cut 50 basis points — its first cut in over four years. Going in, the 30-year fixed had drifted to about 6.08%, a two-year low.

The Fed then cut again in October and again in December: a full percentage point across three meetings.

By January 14, 2025, the 30-year fixed was 7.01%.

Fed down a point. Mortgages up nearly a point. Four months.

September 2025. Fed cut again, to 4.00%–4.25%. Mortgage rates ticked up roughly an eighth to a quarter point in the days that followed.

There's a clean explanation for this, and it's not conspiracy. Markets price expected Fed moves in advance. By the time the chair reaches the microphone, the bond market made its decision weeks ago. What moves rates afterward is what investors think inflation looks like years out — not the announcement.

Which means the cut you're waiting for is, in a real sense, already in your rate.

So what actually happens next week?

The Jackson Hole Economic Policy Symposium runs August 27–29 at Jackson Lake Lodge in Grand Teton National Park — roughly 120 central bankers, economists and policymakers from more than 70 countries.

It is, essentially, Lollapalooza for people who own more than one calculator. Comparable crowd density. Substantially more fleece.

It's also Kevin Warsh's first Jackson Hole as Fed Chair; he was sworn in May 22, 2026. He's signaled a preference for shorter statements and less forward guidance, which one analyst described as a return to "constructive ambiguity." Translated: expect fewer hints, not more.

And a detail worth knowing before you build a plan around it: this year's symposium theme is "Financial Innovation: Implications for Payments and Policy." Digital payments, central bank digital currencies, fintech.

Housing isn't on the agenda. The next actual rate decision comes September 16.

One more piece of context on the committee itself

At the July 29 meeting, the Fed held steady. The vote wasn't unanimous, though — three officials dissented, and all three preferred to raise rates by a quarter point: Beth Hammack, Neel Kashkari and Lorie Logan.

The Fed's own statement noted inflation remains elevated relative to its 2% goal, partly reflecting supply shocks in sectors including energy.

I'm not predicting a hike, and I'm not rooting for one. The point is narrower and worth sitting with: if you've built a timeline around an imminent cut, it's worth knowing that the disagreement inside the room right now runs in the other direction.

Meanwhile, in the market where your actual house is

Here's what Chicagoland is doing while everyone watches Wyoming:

  • City of Chicago median price: $427,500 in June, up 6.9% year over year. Redfin's rolling three-month figure has it at $430,000, up 7.4%.

  • Chicago inventory fell 28.9% year over year — from 4,693 homes to 3,338.

  • Chicago metro (nine counties): median $407,000, up 4.6%, with inventory down 14.4% to 14,992.

  • Homes are averaging about 46 days on market and roughly three offers.

A wrinkle worth knowing: lower rates cut both ways

Here's something that surprises most sellers.

If mortgage rates fall meaningfully, it doesn't only bring buyers off the sidelines. It also brings sellers off the sidelines — every homeowner sitting on a 3.5% mortgage, holding onto it like the last Old Style at a family picnic.

More buyers and more listings. Today's 28.9% inventory shortage would ease.

That's genuinely good news for the market's health, and it's genuinely mixed news if you're the one with something to sell. Worth factoring in either way.

The math, run honestly

Say you're buying a median-ish Chicago home at $430,000 with 20% down.

Today at 6.67%: $344,000 loan. Principal and interest ≈ $2,213/month.

A year from now at 6.00%, with prices up a conservative 5% (they're currently running near 7%): home is $451,500, loan is $361,200. Principal and interest ≈ $2,166/month.

Monthly savings: $47. Roughly four Portillo's combos.

To get there you'd pay $21,500 more for the same house and bring $3,500 more cash to closing — and that's assuming rates actually drop two-thirds of a point.

Now flip it. If rates fall to 6.00% and prices stay flat, that same house at $430,000 runs about $2,063/month — a real savings of $150. So the outcome hinges almost entirely on whether Chicago prices flatten. They haven't in three years, but "haven't yet" is not "won't."

That's the actual bet. Not rates versus no rates — rate relief versus price appreciation.

The honest case for waiting

I'd rather give you this straight than sell you urgency.

Waiting makes real sense if:

  • Your budget is genuinely stretched at today's payment. Buying something you can't comfortably carry is a far bigger risk than mistiming a rate.

  • You'd be selling and immediately rebuying into the same tight market — the arbitrage mostly cancels out.

  • Your life circumstances aren't settled. Real estate rewards a five-year horizon, not a clever quarter.

  • The labor market softens this fall. If it cracks, the 10-year could fall quickly and mortgage rates would follow. That's a real scenario. Fannie Mae and the MBA have both been pointing at the low-to-mid 6s for a while now — they've been early three years running, but early isn't wrong forever.

The honest case for acting now

  • Chicago inventory is down 28.9% year over year. Fewer competing listings is a measurable advantage that costs you nothing.

  • Prices are up 6.9% year over year in the city. Every month of waiting is priced in somewhere.

  • The fall buyer window runs roughly six weeks — active now through mid-October, then thin until February. Call it the first-orange-parking-chair rule.

  • You can refinance a rate. You can't refinance a house someone else bought.

Neither list is the right answer for everybody. Which one describes your situation is the actual question — and it's a much better question than "what will the Fed do."

Practical steps either way

Selling:

  • Price to today's rate environment. Buyers shop by monthly payment, not by list price.

  • Consider offering a rate buydown instead of a price cut. A 2-1 buydown often costs less than a $15,000 reduction and does more for the buyer's payment.

  • Handle roof age, sewer line and insurance history before listing. Those derail more Chicago deals than interest rates do.

Buying:

  • Ask your lender about float-down options. Many exist and most won't be volunteered.

  • Underwrite the payment at today's rate, not a hoped-for one.

  • Get fully underwritten, not just pre-qualified. In a market averaging three offers per home, a clean file is worth more than a clever timeline.

One rate you can actually control

You can't do much about the Federal Reserve. I've checked.

You can decide what it costs to sell your house.

My listing commission is 1.25%. On a $430,000 home, that's a meaningfully smaller line item on your closing statement — roughly $5,375 less than a 2.5% listing side. That's real money, in your pocket, regardless of what happens in Wyoming.

Also included:

  • The Zero Commission Clause — if you find your own buyer, you pay me nothing.

  • Cancel anytime. No six-month lock-in. I'd rather earn it every month.

  • Professional photography, 3D Matterport tours and full online marketing on every listing.

Twenty-five years in this market. Over $100 million closed. City and suburbs.

Nobody can tell you what rates will do. I can tell you what your house is worth today, and what it'll cost you to sell it.
