Iran Conflict Market Impact: What It Means for Mortgage Rates

A client-ready comparison of the 2-year Treasury, 10-year Treasury and WTI crude oil—plus what Freddie Mac’s strong quarter really tells us about housing.
Market update: July 31, 2026
Date correction: The 2026 Iran war began February 28. Therefore, Friday, February 27 is the proper pre-conflict market baseline. March 25 was approximately Day 26 of the conflict, so it is shown as a separate checkpoint.

What this means for mortgage rates

Near-term rate signal: unfavorable

  • The 10-year Treasury is about 70 basis points above its pre-conflict level.
  • Oil remains roughly 26% higher, increasing inflation risk.
  • The 2-year yield says markets expect monetary policy to remain restrictive.
  • These forces make a major mortgage-rate decline harder without softer inflation, weaker employment or de-escalation.

Housing-system signal: positive

  • Freddie Mac earned $3.8 billion in Q2 and increased net worth to $77.8 billion.
  • It financed 306,000 single-family mortgages, including 97,000 first-time-buyer purchases.
  • A stronger GSE supports liquidity and continued access to conventional mortgage credit.
  • This supports stability, but it does not directly reduce a borrower’s interest rate.

Freddie Mac: read beyond the headline

The accurate takeaway: Freddie Mac’s results are good news for housing-market resilience and mortgage availability—not a rate-cut signal. The 61% increase in net income was helped substantially by an $880 million credit benefit tied to updated home-price scenarios. Net revenue grew only 1%, while net interest income grew 13%.

Client-ready talking point

“Freddie Mac is financially stronger and continues financing hundreds of thousands of families, so the mortgage system itself remains healthy. But the market forces that determine your rate are still working against us. Since the day before the Iran conflict, the 10-year Treasury is up about 70 basis points and oil is still roughly 26% higher. That combination keeps inflation concerns alive and makes it difficult for mortgage rates to fall sharply. Good news for housing stability does not automatically mean lower rates today.”

What to watch next

#1

Oil below $80

A sustained decline would reduce some energy-driven inflation pressure.

#2

10-year below 4.25%

A meaningful Treasury rally would create a better backdrop for mortgage pricing.

#3

MBS spreads

Mortgage rates can improve further if agency mortgage-backed securities outperform Treasuries.

Sources and methodology

Treasury yields: U.S. Department of the Treasury, Daily Treasury Par Yield Curve Rates. Feb. 27: 2-year 3.38%, 10-year 3.97%. March 25: 2-year 3.84%, 10-year 4.33%. July 30 official close: 2-year 4.23%, 10-year 4.68%. July 31 intraday quotes: 2-year approximately 4.256%, 10-year approximately 4.669%.

Oil: U.S. Energy Information Administration Cushing, Oklahoma WTI spot series for Feb. 27 ($66.96) and March 25 ($91.51). July 31 uses the intraday WTI front-month market quote ($84.15), because the EIA daily spot series is released with a lag.

Conflict date: Reuters and the UK House of Commons Library identify February 28, 2026 as the beginning of the U.S.-Israel strikes on Iran.
