Mortgage Rates Tick Higher as Oil Prices Rise
After ending last week near their lowest levels since mid-July, mortgage rates moved modestly higher to start the new week.
The culprit? A familiar combination: geopolitical tension, oil prices, and the bond market.
Headlines surrounding escalating tensions with Iran put upward pressure on oil prices, particularly after reports that Iran seized a UAE tanker in the Strait of Hormuz. As oil prices climbed, the 10-year Treasury yield followed—and mortgage rates moved with it.
Where Rates Are Today
The average top-tier 30-year fixed mortgage rate increased about 0.02% to 6.73%.
For perspective:
Today: 6.73%
Last Thursday: 6.69%
Recent high: 6.85%
So while rates gave back a little ground, they're still considerably better than the recent highs.
Why Does Oil Matter to Mortgage Rates?
Higher oil and fuel prices can increase inflation expectations. Inflation is important to the bond market, and mortgage rates tend to move closely with bond yields.
That means developments overseas can quickly find their way into what a homebuyer sees on a mortgage quote here at home.
What This Means for Buyers
A 0.02% move isn't dramatic, but it's another reminder that mortgage rates can change quickly—even when nothing changes with the borrower.
If you're shopping for a home, don't let small day-to-day rate movements take you out of the game. Instead, know your numbers, understand your payment options, and have a strategy ready when the right house comes along.
And remember: the rate is only one piece of the mortgage puzzle. Loan structure, seller concessions, temporary buydowns, points and other strategies can sometimes make just as much difference.
