Mortgage rates surge to the highest since June 2025 as new Middle East attacks push oil prices up

• The 30-year fixed mortgage rate rose to 6.87%, up 12 basis points since Thursday and nearly 90 basis points since late February before the Iran war began
• Monthly payments on a $450,000 home (national median) are now $2,363, which is $207 more per month than at the end of February when rates were 5.99%
• Home prices nationally rose 1.5% year-over-year in June, accelerating from May's 1.2% gain, as tight supply and homeowners reluctance to give up low existing mortgages constrain the market

Summary

Key Developments:

Mortgage rates have surged to their highest level since June 2025, with the average 30-year fixed mortgage rate reaching 6.87% on Monday—a 6 basis point jump in one day and 12 basis points higher than Thursday. The rate has climbed over 30 basis points in the past two months.

Primary Driver:

The escalation in the Iran war has pushed oil prices higher, driving up bond yields, which mortgage rates typically follow. Rates stood at 5.99% at the end of February, before the conflict began.

Market Impact:

For a median-priced $450,000 home with 20% down, monthly principal and interest payments now total $2,363—$207 more per month than late February. Higher rates also restrict borrower qualification by adversely affecting debt-to-income ratios used by lenders.

Housing Market Conditions:

The rate surge compounds existing affordability challenges from accelerating home prices. The S&P CoreLogic Case-Shiller home price index shows national prices rose 1.5% year-over-year in June, up from 1.2% in May, driven by lean inventory. Current homeowners remain reluctant to sell and forfeit their lower locked-in rates from previous years.

Analyst Perspective:

Matthew Graham, COO of Mortgage News Daily, characterized the increase as a "slow grind" fueled by inflation expectations, elevated bond issuance, and economic resilience rather than sudden momentum. These factors remain subject to future variability.

Outlook:

The current trajectory contradicts earlier expectations for declining rates in 2025, with geopolitical tensions continuing to influence financial markets and housing affordability.
