Mortgage Rates Improve Slightly as Iran Ceasefire Talks Calm Markets

After several difficult weeks for mortgage rates, markets finally showed signs of stabilization this week.

Mortgage bonds improved for a second straight day as reports surfaced that negotiations between the United States and Iran may be moving closer toward a broader ceasefire agreement. Oil prices also reversed sharply lower, helping ease immediate inflation concerns that had been driving rates higher throughout May.

The central issue remains the Strait of Hormuz.

Roughly 20% of the world’s oil supply moves through this narrow waterway, making it one of the most important shipping routes globally. Any disruption there immediately impacts energy prices, inflation expectations, and ultimately mortgage rates.

Over the past month, rising oil prices helped push Treasury yields sharply higher and created another wave of mortgage rate volatility. Markets feared that prolonged disruptions could keep inflation elevated much longer than expected.

This week brought some relief.

Oil prices fell back below $100 per barrel after reports that diplomatic negotiations may be narrowing key disagreements between Washington and Tehran. Mortgage-backed securities rallied alongside Treasuries, allowing lenders to modestly improve rate sheets.

However, the market remains extremely headline-driven.

If negotiations continue progressing

:• Rates could gradually improve into June

• Inflation fears may ease

• Bond markets could stabilize further

If talks break down:

• Oil prices could spike again

• Treasury yields could move back higher

• Mortgage pricing could worsen quickly

Housing fundamentals themselves have not changed dramatically.

Inventory remains relatively constrained in many markets, affordability remains challenging, and many homeowners continue sitting on substantial equity positions.

Buyers also continue benefiting from less competition compared to the peak frenzy years.

The key takeaway:

Markets have improved, but volatility has not disappeared. This remains a market where preparation, flexibility, and strategy matter far more than trying to perfectly time rates day-to-day.
