Fed Funds Rose to 3.75%. Treasuries Still Aren’t Convinced

The Federal Reserve’s effective federal funds rate rose to 3.75% in September 2026 from 3.63% in August, a 12 basis point increase that on its own would usually reinforce a straightforward inflation-fighting story. But that is not how the bond market traded it.

Instead, Treasuries split. On October 7, the 2-year yield fell 2 basis points to 4.77% while the 10-year yield rose 1 basis point to 5.28%. By October 8, the 10-year minus 2-year spread had narrowed to 0.47% from 0.51% a day earlier. That is a small move in absolute terms, but it matters because it shows investors are not simply extending a clean “higher rates for longer” view. They are repricing near-term policy and longer-run growth at the same time.

For households and businesses, that distinction matters. A higher policy rate keeps pressure on short-term borrowing costs, while elevated long-end yields keep mortgages and other longer-duration financing expensive. In other words, the Fed can still look restrictive even if markets are becoming less convinced about the economy’s ability to absorb more of it.

The policy rate rose, but the market reaction was less straightforward

The higher effective funds rate arrived alongside inflation readings that still look firm. The Consumer Price Index rose 0.4% month over month in August to 334.13, while the Personal Consumption Expenditures Price Index increased 0.31% over the same period. Those are not numbers that suggest inflation has cleanly rolled over.

Normally, that kind of backdrop would support a more uniform move higher in front-end yields. Instead, the 2-year Treasury yield moved lower even as the 10-year edged up. With no single verified external catalyst attached to the move in the research package, the safest reading is that markets are still struggling to decide which risk matters more right now: inflation staying sticky, or growth weakening under already restrictive conditions.

That is why the fed funds print, while important, does not settle the bigger macro question. The market is treating the current stance as restrictive, but not necessarily as a guarantee of durable growth resilience.

A flatter curve points to pressure on growth-sensitive parts of the economy

The narrowing in the 10-year minus 2-year spread to 0.47% from 0.51% is the clearest sign of that tension. A flatter curve here does not read like confidence in a smooth expansion. It reads more like a market that still sees inflation pressure, but is becoming more careful about the growth trade-off.

That matters most in rate-sensitive areas. Housing already looks vulnerable: housing starts fell about 2.6% in August, and the MBA 30-year mortgage rate climbed to 7.49% in the latest weekly reading available in the data package. Mortgage applications also fell 4.2% in that same weekly update, while the purchase index slipped to 145.1 from 148.2 and the refinance index dropped to 515.8 from 557.8.

Those are practical consequences, not just market abstractions. When long-term yields stay high, homebuyers face higher monthly payments, refinancing becomes less attractive, and housing activity tends to stay under pressure even if the market is no longer pricing an uninterrupted march higher in short-term rates.

Labor and spending still look decent, but confidence is softer

The reason this story is not a clean recession call is that other parts of the economy have not broken decisively. The unemployment rate held at 4.2%, and nonfarm payrolls edged higher in September from August. Retail sales rose 1.13% in August, showing that consumer demand has not rolled over.

But the softer side of the picture is becoming harder to ignore. The University of Michigan consumer sentiment index fell 6.3% to 51.7, and consumer credit growth slowed sharply in the latest calendar reading, with August consumer credit change at 8.28 versus 17.74 previously. Even if spending is still holding up, weaker confidence and slower credit growth can matter later because they hint at a consumer that may be becoming more selective rather than more resilient.

That mix helps explain the Treasury split. Strong enough data can keep inflation worries alive, but not strong enough to remove doubts about how long households can keep absorbing high borrowing costs.

The dollar move also suggests markets are not chasing a one-way tightening trade

The trade-weighted U.S. dollar index slipped 0.33% in its latest reading. That is not a dramatic move, but it fits the broader pattern: tighter policy expectations are being weighed against a more complicated macro backdrop rather than producing a simple rush into the dollar.

For cross-asset readers, the main takeaway is restraint. The available data package does not verify a clean, broad-based move across stocks, gold or crypto tied to this exact repricing, so the article should not overstate that part of the reaction. What is verified is the rates signal: front-end yields eased, long-end yields stayed elevated, and the curve flattened. That combination usually matters most for financing conditions first, then for risk appetite later if incoming data confirms slower growth.

The next test is whether September inflation confirms or breaks this tension

The next major checkpoint is September CPI on October 14, 2026. Estimates in the calendar point to 0.5% month-over-month headline inflation, up from 0.4% previously, with year-over-year CPI seen at 3.6% versus 3.4% prior. Core CPI month over month is estimated at 0.2%, down from 0.3%.

Before that, investors were also set to watch the October University of Michigan sentiment release on October 9, with consumer sentiment estimated at 47.6 versus 48.1 previously, alongside slightly higher 1-year and 5-year inflation expectations.

Those releases matter because they could resolve the current split in market pricing. If inflation stays firm and expectations drift higher, front-end yields could resume climbing and bring the policy story back to the center. If confidence weakens further and demand data softens, the market’s current caution on growth may look more justified.

For now, the important point is that a 3.75% effective fed funds rate has not produced a single, settled macro narrative. Inflation is still sticky enough to keep the Fed under pressure, but the bond market is signaling that growth confidence is not keeping pace.
