What are mortgage rates on May 18, 2026?

Daily 30-year fixed mortgage rates ranged from 6.49% to 6.64% on May 18, 2026, with 30-year refinance quotes at 6.84% (+16bp day-over-day). Freddie Mac's most recent weekly PMMS print was 6.36%. The 10-year Treasury yield closed at a six-week high after rising about 17bp over the week, driven by Iran-related oil pressure and the hot April CPI (3.8% YoY) and PPI (6.0% YoY) prints.

How much does +26bp on a 30-year mortgage cost?

On a $400,000 30-year fixed loan, moving from 6.23% (April low) to 6.49% adds about $68 to monthly principal and interest ($2,459 to $2,527). Over 30 years that is roughly $24,500 in extra interest. On a $500,000 loan the monthly impact is about $86 and lifetime interest rises by roughly $30,800.

Why are mortgage rates rising if the Fed is on hold?

Mortgage rates track the 10-year Treasury yield, not the Fed funds rate directly. The 10-year hit a six-week high on a combination of Iran-driven oil pressure, hot April inflation (CPI 3.8%, PPI 6.0%), and markets repricing out 2026 rate cuts. The 30-year mortgage / 10-year Treasury spread has also widened back toward 2.2 percentage points, well above the long-run average of about 1.7pp, which adds to the move.

Should I lock my mortgage rate before the June 17 FOMC meeting?

If you have a ratified contract and are within 30-45 days of closing, locking now is the safer play. Markets are pricing zero 2026 rate cuts, and the next CPI release (June 11) plus FOMC (June 17) are more likely to push rates higher than lower given the recent inflation trajectory. Floating only makes sense if you have a long closing window and tolerance for a 20-40bp adverse move.

What is the 30-year mortgage to 10-year Treasury spread?

The spread is the gap between the average 30-year fixed mortgage rate and the 10-year Treasury yield. It compensates investors for prepayment risk and credit servicing costs. Historically it averages 1.5-1.8 percentage points. As of mid-May 2026 it sits near 2.1-2.2pp with the 10-year around 4.4% and 30-year mortgages near 6.5%, signaling stressed mortgage-bond demand.

Are mortgage rates expected to fall in 2026?

Bankrate's mid-May rate-cut survey now shows Wall Street pricing in zero 2026 Fed cuts, down from 2-3 cuts expected in January. For mortgage rates to fall meaningfully toward 5% would require either core PCE returning to the Fed's 2% target, a sharp drop in oil prices, or the 30-year/10-year spread narrowing by 30-50bp toward its long-run average. None of those look imminent.

What +26bp actually costs you

A 26-basis-point move sounds small. On a real mortgage payment over 30 years, it is not. The table below assumes a 30-year fixed loan with no points and no PMI, at the principal-and-interest level only.

Loan amount	P&I at 6.23%	P&I at 6.49%	Monthly cost	Lifetime interest cost
$300,000	$1,844	$1,895	+$51	+$18,400
$400,000	$2,459	$2,527	+$68	+$24,500
$500,000	$3,074	$3,159	+$86	+$30,800
$750,000	$4,610	$4,739	+$129	+$46,200

Put differently: if you were pre-approved at the April low and your budget topped out at a $2,459 P&I payment, the same payment now buys you about $390,000 in loan instead of $400,000. That is a 2.5% haircut to purchase power in roughly six weeks.

Why is the 10-year Treasury moving?

Three things drove the May 12–18 move in the long end:

Hot April CPI (3.8% YoY headline, 2.8% core). The May 12 BLS print was above 3.7% consensus and the highest YoY reading since May 2023. Energy ran +17.9% YoY with gasoline +28.4%.
Hot April PPI (+6.0% YoY, +1.4% MoM). The May 13 wholesale-price release was the biggest monthly jump in years. Gasoline drove about 40% of the increase, signaling more pipeline inflation into May and June CPI.
Iran oil risk premium. Brent has held above $104 and intermittent Strait of Hormuz disruptions are now baked into term premium on long-dated Treasuries. Redfin's May 18 weekly note framed Middle East tensions, not US data, as the dominant rate driver this week.

The spread is widening again

Mortgage rates do not track the Fed funds rate directly. They track the 10-year Treasury, plus a spread to compensate investors for prepayment risk and servicing costs. That spread averaged about 1.7 percentage points in the decade before 2022. As of May 18 it sits near 2.05–2.2pp (6.49% mortgage minus 4.45% Treasury).

For mortgage rates to fall meaningfully without a Fed pivot, the spread has to narrow. That requires healthier MBS demand from banks and the Fed, which is not happening while the Fed is still running off its mortgage-bond portfolio at the cap.

Lock or float into June 17 FOMC?

Markets are now pricing zero 2026 Fed cuts, per Bankrate's May 18 rate-cut survey — a sharp reversal from the 2–3 cuts pencilled in back in January. Between now and the June FOMC, the rate-relevant prints are:

May 30: April PCE (Fed's preferred gauge).
June 6: May jobs report.
June 11: May CPI.
June 17: FOMC decision and SEP dots.

Three of those four releases are more likely to push rates higher than lower given current trajectory. If you have a ratified contract and are inside a 30–45 day closing window, locking is the safer play. Floating only makes sense if you have a long closing window and the budget to absorb another 20–40bp adverse move.

Frequently asked questions

What are 30-year mortgage rates today?

Daily 30-year fixed quotes were 6.49–6.64% on May 18, 2026, with 30-year refinance at 6.84%. Freddie Mac's weekly PMMS print was 6.36%.

How much does a 0.25% rate change cost on a $400k mortgage?

About $66 per month and roughly $23,800 in lifetime interest on a 30-year fixed loan, holding everything else constant.

Why are mortgage rates rising when the Fed has not hiked?

Mortgage rates follow the 10-year Treasury, not the Fed funds rate. The 10-year is up on hot April CPI and PPI, Iran oil pressure, and markets pricing out 2026 cuts. The mortgage-Treasury spread has also widened back toward 2.2pp.

Should I lock my mortgage rate now?

If your closing window is under 45 days, lock. The next CPI print (June 11) and FOMC meeting (June 17) skew toward higher rates given the current inflation trajectory.

Will mortgage rates drop in 2026?

Wall Street is pricing zero 2026 Fed cuts as of mid-May. A move toward 5% would require core PCE back to 2%, lower oil, or a meaningful narrowing of the mortgage-Treasury spread. None of those look imminent.
