Why Mortgage Rates Don't Follow the Fed — And What Actually Drives Them

Update (Oct 2026): Rates have since risen. The 30-year fixed averaged 7.40% the week of Oct 15, 2026 (Freddie Mac PMMS). The analysis below reflects conditions when this was published.

The Federal Reserve has cut interest rates six times since September 2024, a total of 175 basis points. The federal funds rate went from 5.25–5.50% down to 3.50–3.75%.

So why was the 30-year mortgage rate still at 5.98% as of February 2026?

It was the single most common question I got from buyers in early 2026, and the answer is one of the most misunderstood parts of real estate: the Fed does not set mortgage rates.

What the Fed controls

The federal funds rate is the rate banks charge each other for overnight loans, so it's a short-term rate in the most literal sense. When the Fed cuts it, the change flows directly into credit card APRs, auto loans, and home equity lines of credit (HELOCs), because those are all tied to short-term lending.

A 30-year fixed mortgage is a different animal. You're locking in a rate for three decades, and lenders price that off the bond market, specifically the 10-year U.S. Treasury yield.

Mortgages price off the 10-year Treasury

The 10-year Treasury yield is what investors demand to lend money to the U.S. government for 10 years. It bakes in expectations about inflation, economic growth, and risk over that horizon. A 30-year mortgage has a similar duration profile (most mortgages are paid off or refinanced within 10 years), so mortgage lenders price their rates as a spread above the 10-year Treasury yield.

Here's where things stood as of February 2026:

The Fed cut 75 basis points over the past year, but the 10-year Treasury fell only 43 basis points. Long-term yields are driven by market forces such as inflation expectations, global capital flows, and government debt supply, and Fed policy is only one input.

Mortgage rates still fell 78 basis points year over year, because they had two tailwinds: a lower Treasury yield and a narrower spread.

The mortgage-Treasury spread

The gap between the 10-year Treasury yield and the 30-year mortgage rate is called the mortgage-Treasury spread. If the Treasury yield is the cost of raw ingredients, the mortgage rate is the price on the menu, and the spread is the restaurant's markup.

That markup moves with risk conditions in the mortgage-backed securities (MBS) market, and for the past few years it's been abnormally wide:

The spread blew out in 2022–2023 because the Fed was letting its mortgage-backed securities run off its balance sheet (quantitative tightening), the banking sector was stressed after SVB collapsed, and prepayment risk was elevated. All of that made investors demand a bigger premium to hold mortgage debt.

Since then, the spread has been compressing, slowly returning toward the historical average of ~170 bps. The Federal Housing Finance Agency (FHFA) directing $200 billion in MBS purchases helped, and so did calmer credit conditions and reduced volatility.

If the spread alone normalizes from 196 bps to 170 bps, mortgage rates drop another quarter point with no help from the Fed. Based on February 2026 levels, that would put the 30-year rate in the mid-5% range, the lowest since 2022.

What the yield curve shows

The other indicator I watch is the yield curve, specifically the spread between the 10-year and 2-year Treasury yields.

When the 2-year yield exceeds the 10-year yield, the curve is "inverted." An inverted yield curve has preceded every U.S. recession since the 1970s. From mid-2022 through most of 2024, the curve was deeply inverted, the longest inversion in modern history.

That inversion is over. As of February 2026, the 10-year yield sits about 59 basis points above the 2-year yield, so the curve is normal again. Bond markets are pricing in moderate economic growth rather than imminent recession.

For housing, a normal yield curve means long-term rates (including mortgages) are priced on growth expectations rather than fear. It doesn't guarantee rate declines, but it removes the recession-driven volatility that made mortgage pricing erratic over the past two years.

The Fed's path from here

Here's every Fed decision since the rate-cutting cycle began:

The Fed held in January 2026 and signaled a cautious pace going forward. Markets are pricing one more cut in mid-2026, but the dot plot (Fed officials' own rate projections) suggests the days of aggressive cuts are behind us. Inflation remains "somewhat elevated" according to the FOMC statement, and the Fed expects it to stay above 2% until 2028.

I wouldn't bank on Fed cuts alone to push mortgage rates significantly lower. The more meaningful variable is the mortgage-Treasury spread. If it keeps compressing toward the 170 bps historical average, rates can improve independent of Fed action.

What this means for NJ buyers and sellers

This is how I was framing it for clients as of February 2026.

For buyers

Sub-6% mortgage rates are the best we've seen since September 2022 (over three years). As of February 2026, the drop many buyers had been waiting for had arrived. I wouldn't hold out for 4% rates, which would require the 10-year Treasury to fall to ~2.3%, a level we haven't seen since the pandemic. Today's (February 2026) rates are workable, and the spring 2026 market will be more competitive than the winter market you're in right now.

For sellers

The lock-in effect is starting to crack. Homeowners who bought or refinanced at 3–4% have been reluctant to sell and take on a higher rate. As rates move into the mid-to-high 5% range, more of them will move, because life events (job changes, growing families, downsizing) eventually override rate math. I'd expect inventory to improve gradually through 2026.

For investors

Watch the spread. If the mortgage-Treasury spread normalizes to 170 bps and the 10-year holds around 4%, that's a 5.70% mortgage rate, meaningfully better for cash flow analysis. Run your numbers at both 5.98% and 5.70% to see how sensitive your deal is. The NJ investment calculator lets you model different rate scenarios.

For refinancers

If you bought in 2023 or early 2024 and locked in above 6.75%, the February 2026 rate already saves you money. A $500K loan at 6.76% vs. 5.98% saves approximately $260/month.

What to watch

The 10-year Treasury yield and the mortgage-Treasury spread tell you more about where mortgage rates are headed than any FOMC press conference does.

As of February 2026, both indicators were moving in the right direction. Rates just broke below 6% for the first time in three and a half years, the spread is compressing toward historical norms, and the yield curve is signaling stable growth rather than recession.

This is the most favorable rate environment for NJ buyers since 2022, though it may not last.
