MODERATE IMPACT

Will mortgage rates go up because of the Iran war?

Quick answer: Mortgage rates may fluctuate. The 10-year Treasury yield has risen, which typically pushes mortgage rates higher. However, a flight to safety could also push rates down if recession fears grow.

How War Affects Mortgage Rates

Mortgage rates are closely tied to the yield on the 10-year U.S. Treasury note. Since the conflict began:

  • The 10-year Treasury yield rose over 4 basis points to 4.173% in the first week of the conflict (CNBC, March 10)
  • Rising oil prices create inflationary pressure, which can push interest rates higher
  • However, geopolitical uncertainty can also trigger a “flight to safety” into bonds, which would push yields (and mortgage rates) down

What This Means for Homebuyers

If you’re buying a home:

  • Rates may be volatile in the short term — expect ups and downs week to week
  • Consider locking your rate if you find an acceptable one, rather than gambling on timing
  • The war adds uncertainty but isn’t the only factor — Fed policy, jobs data, and inflation all matter

If you already have a mortgage:

  • Fixed-rate mortgages are unaffected by any changes
  • Adjustable-rate mortgages (ARMs) could see higher payments at reset if rates rise
  • Home equity lines of credit (HELOCs) may see rate increases

If you’re refinancing:

  • Monitor rates closely — there may be brief windows of opportunity when safety buying pushes yields down
  • Don’t wait for a “perfect” rate in volatile times

Global Housing Impact

Europe: The European Central Bank faces pressure from both rising energy costs (inflationary) and slowing growth (deflationary). Mortgage rates in the EU may diverge from US rates.

UK: The Bank of England is navigating similar competing pressures. UK fixed-rate deals may become more expensive.

Australia: The Reserve Bank of Australia had been considering rate cuts, but energy-driven inflation could delay those plans.

Canada: Canadian mortgage rates tend to follow US trends. The Bank of Canada faces similar inflation vs. growth tensions.

What Economists Are Saying

The consensus is that the war’s impact on mortgage rates is uncertain because two forces are pulling in opposite directions:

  1. Higher inflation from oil prices — pushes rates UP
  2. Recession fears and flight to safety — pushes rates DOWN

The net effect will depend on how long the conflict lasts and how severely it disrupts the global economy.
