FOMC Reaction Edition — the decision, the press conference, and what it means| Next jobs report: Friday, October 2| Next FOMC: late October

A note on timing: we're publishing this the morning after rather than in the 2:15 scramble. Wednesday's decision was priced at better than 90% odds, so the news was never the hike — it was the vote count, the tone, and the bond market's answer. Those are all clearer with a night behind them. Everything below reflects the decision, the press conference, and the immediate market reaction; where the rally goes from here is the open question, and it's the one we'll be watching for you this week.

01

The Decision: Unanimous, and Historic

Yesterday at 2:00 p.m. the Federal Open Market Committee voted 12–0 to raise the federal funds rate by a quarter point, from a range of 3.50%–3.75% to 3.75%–4.00%. It is the first rate increase since July 2023, and it comes after the Fed left rates unchanged at each of its first five meetings this year. Markets had priced the move at better than 90% odds — but the unanimity is the part worth pausing on.

Remember where this committee was seven weeks ago. On July 29, Warsh held rates and three members — Hammack, Kashkari, and Logan — dissented in favor of a hike, the first unified three-way hawkish dissent since September 2016. Their argument was that holding while inflation ran above target, with financial conditions that weren't restrictive, was itself a form of loosening. Yesterday, every single member came to their side. The dissenters didn't just win the argument; they won it 12–0.

The updated Summary of Economic Projections carried its own signal: the median Fed official now expects one more rate hike before the end of this year. One institutional footnote that caught our eye — Warsh confirmed he did not submit his own projections to the SEP, which is consistent with a chair who has spent his tenure dismantling forward guidance and refuses to give markets a personal roadmap.

02

What Warsh Said

The press conference was the most direct we've heard from him. On the why: "The plain fact is that inflation is too high, and has been for too long." He noted that recent summer inflation readings had not shown meaningful improvement in the underlying trend — the same argument he made at Jackson Hole, now backed by a vote.

On the economy, he was notably upbeat: "Our decision comes at a time when the American economy appears to be strengthening," citing labor market data, private sector earnings, and capital investment, and pointing to a low jobless rate with job openings and hours rising. And the line that tells you the most about where this is heading: "I would be hard-pressed to describe broad financial conditions as restrictive." Translation — he doesn't think this hike is tight money. He thinks it's a step toward normal.

He committed to a "timelier return" to 2% inflation while making no promises about when that arrives, conceding price stability has been elusive for five and a half years. He rejected the idea that either the White House or the bond market drove the decision, saying the committee reached it by evaluating the economy. And he framed the whole thing in a way we haven't heard from a Fed chair in a while: the hike is good news for the "least well-off" Americans — the people who don't own financial assets or have home equity built up, and who get hurt most by rising prices.

03

The Reaction That Proves the Whole Point

Here is the single most important paragraph in this issue. In the minutes after the Fed raised rates, U.S. equities accelerated and Treasury yields fell. The Fed hiked, and the bond market that determines your mortgage rate rallied.

We have now written this three times in three weeks, so let's score it honestly:

What We SaidWhat Happened
Aug 28: "The thing that lowers your mortgage rate isn't a friendly Fed — it's a believable one." Held up. A credible hike produced falling long yields, exactly as the mechanism predicts.
Sep 11: "If the Fed hikes Wednesday, you'll see 'mortgage rates are going up because the Fed raised rates' everywhere. It's not that simple." Confirmed today. Rates went up at the Fed and yields went down in the market, in the same hour.
Sep 11: "A widely expected hike is already in today's pricing." Right. At 90%+ priced, the decision itself carried almost no new information — the tone did.
⚑ Why It Works This Way

Your mortgage rate is not priced off the fed funds rate. It's priced off long-term bond yields — and those move on what investors expect inflation to be over the next decade. When the Fed hikes decisively and explains it credibly, long-term investors become more confident that inflation gets contained, so they accept lower yields on 10- and 30-year debt. That's what happened yesterday, and it's the same mechanism we described after Jackson Hole. One market strategist put it well on Yahoo Finance: the Fed retained its credibility and "did the right thing," which could cause long-term yields to fall a bit and in the long run be good for borrowers. The hike was the price of admission. Credibility is the product.

04

Two Very Different Bills Arrive Now

This is where we need you to separate two things that get lumped together every time the Fed moves.

The immediate, direct hit: variable-rate debt. The prime rate moves in lockstep with the fed funds rate, so it goes from 6.75% to 7.00% within days. Every HELOC, credit card, and variable business line reprices almost immediately. As one analyst summarized today: home equity lines, credit card rates, and auto loans are short-term instruments, so "not necessarily a good thing." In dollars, a quarter point costs about $125 a year on a $50,000 HELOC balance, or roughly $250 a year on $100,000. Not catastrophic — but it's real, it's automatic, and it compounds if the dot plot's second hike arrives.

The indirect, ambiguous one: your mortgage. Nothing about today automatically raises a 30-year fixed rate. Today it arguably helped. The honest caution alongside that: the recent trend in mortgage rates has not been good — the 30-year has been running near 6.76% to 6.81%, at one-year highs, after the 10-year Treasury touched 5% last Friday. Today's rally is one afternoon against three weeks of pressure. We'd call it encouraging, not decisive.

What We'd Do Now

If you have a HELOC balance — act this week. This is the most concrete action item in this issue. Your rate is going up within days, and the dot plot says another increase is likely before year-end. If you've been carrying a balance you meant to consolidate or convert to a fixed product, the math just got worse and is scheduled to get worse again. Home equity loans are fixed; HELOCs are not. Know which one you're holding.

If you're closing in the next 45 days: the case for locking with a float-down is unchanged and yesterday doesn't alter it. Yes, yields fell on the announcement — but the 10-year touched 5% last Friday, published mortgage indexes still lag the bond market, and the committee has one more hike penciled in. Lock the certainty and let the float-down capture any credibility rally that develops.

If you're waiting to refinance: yesterday was the first genuinely constructive development in weeks, and we want to be careful not to oversell it. The path that helps you is exactly what began at 2:00 yesterday — the Fed establishing enough credibility that long yields drift down — combined with oil easing off its highs. Watch the 10-year, not the headlines about hikes. Keep the file staged.

And for everyone, especially our agent readers: you are going to hear "the Fed raised rates, so mortgage rates are going up" constantly over the next several days. It is wrong, and yesterday handed us the cleanest proof we've ever had: the Fed hiked at 2:00 and bond yields fell by 2:15. If a client or a colleague repeats it, forward them this issue. Being the person in the room who understands that distinction is worth real credibility right now.

Fri Oct 2 September Jobs Report First labor read since the hike · Flash edition
Mid-Oct September CPI Does the core breadth from August persist? Date verified before we print it
Late Oct Next FOMC Meeting Goldman Sachs and J.P. Morgan both expect a December hike

The forecasting community has already moved: both Goldman Sachs and J.P. Morgan expect another increase by December, which lines up with the dot plot's median. And the data keeps cooperating with the hawks — this morning's August retail sales showed a sharp rebound from July's decline, reinforcing the picture of an economy that is, in Warsh's words, strengthening.

07

The Bottom Line

The Fed raised interest rates for the first time in three years, unanimously, and told us it probably isn't finished. That should be unambiguously bad news for borrowers. Instead, the bond market that actually sets your mortgage rate rallied — because a central bank that finally acts on inflation is a central bank that long-term investors can lend to more cheaply.

So here's the balance sheet. If you carry variable-rate debt, the bill arrives within days and it's real. If you're buying or refinancing a home, yesterday was cautiously encouraging after three punishing weeks — one afternoon of relief that needs several more sessions to become a trend, which is exactly what this week will tell us. And if you've been following along since Jackson Hole, you watched a mechanism we described in theory play out in public twice in three weeks. Credibility is the cheapest thing a central bank can give a mortgage borrower, and on Wednesday it gave some.

If you're mid-process or carrying a HELOC balance, run the numbers today — the prime rate change is landing right now. Reach out any time. That's what I'm here for. — Ryan
