Following the market closely as closely as I do, I’ve seen geopolitical events shake things up before—but the current conflict with Iran is playing out differently than many expected when it comes to mortgage rates. If you’re a homebuyer, seller, or homeowner thinking about refinancing, this one’s worth paying attention to. Let’s break down exactly what’s happening, why it’s bucking historical trends, and what it could mean for your next move.

Rates Were Finally Dropping—Then the Conflict Hit

At the end of February 2026, we were celebrating a real milestone. The average 30-year fixed mortgage rate had dipped to 5.98% according to Freddie Mac—the first time it had fallen below 6% since 2022. Homebuyer affordability was finally getting a breath of fresh air after years of higher borrowing costs. Then, on February 28, the U.S. and Israel launched strikes on Iran. Almost immediately, the positive momentum reversed. Mortgage rates jumped sharply. By early March, the average climbed to around 6.12%, and as of the week ending March 12, Freddie Mac reported it at 6.11%—with some daily trackers showing even higher levels around 6.3–6.5% depending on the lender and points. In short: rates moved in the negative direction for borrowers right as the conflict escalated. That’s the opposite of what a lot of market watchers anticipated.

Why This Time Is Different: Oil, Inflation, and the Bond Market

Mortgage rates are closely tied to the 10-year U.S. Treasury yield and the broader bond market (specifically mortgage-backed securities). Historically, geopolitical conflicts like this one have been good for bonds. Investors get nervous about uncertainty and flock to the safety of U.S. Treasuries—a “flight to quality” that drives bond prices up and yields (and therefore mortgage rates) down.

We’ve seen it time and again: during past Middle East tensions, the Gulf War era, or even in the immediate aftermath of 9/11, the safe-haven rush often provided relief on borrowing costs. Bond buyers stepped in, yields fell, and mortgage rates followed suit, giving the housing market a bit of a tailwind. But this conflict with Iran flipped the script from day one. Why?

The big culprit: oil prices. Iran’s strategic role in global energy (think the Strait of Hormuz) sent crude oil surging amid fears of supply disruptions. Higher energy costs feed directly into inflation expectations. Investors started demanding higher yields on bonds to compensate for that inflation risk, pushing the 10-year Treasury yield from a recent low near 3.9% back above 4.2%. Mortgage rates followed right along. Added volatility in the mortgage-backed securities market made lenders even more cautious, widening spreads and adding a few extra basis points to the rates you see quoted. The usual safe-haven benefit was there briefly, but inflation fears from the “oil shock” won out—at least in these early weeks.

What This Means for the Housing Market Right Now

The timing couldn’t be more frustrating for the spring buying season. Just as rates were improving affordability and purchase applications were starting to pick up, this reversal has introduced new uncertainty. Pending home sales showed some resilience in February, but experts are watching closely to see if higher rates will cool buyer demand heading into peak season. On the positive side, rates are still meaningfully lower than they were a year ago (when they hovered around 6.65%). And if the conflict remains contained or oil prices stabilize, history suggests these initial spikes can retrace as markets digest the news and the safe-haven flows regain the upper hand.

The Federal Reserve’s path for rate cuts is also a bit cloudier now. Inflation worries tied to energy could keep the Fed on hold longer than hoped, which keeps pressure on mortgage rates.

What Homebuyers and Homeowners Should Do

1. Don’t panic—but don’t wait forever. If you’re in the market to buy, get pre-approved and shop multiple lenders. Even small differences in rate quotes or fees can add up.
2. Consider locking in. If you’ve found a home and rates are still in the low-to-mid 6% range, a rate lock can protect you from further volatility while your loan is processed.
3. Evaluate affordability carefully. Run the numbers with today’s rates (and a few scenarios if they move another quarter-point). Tools like payment calculators are your friend.
4. Refinancing? Existing homeowners with rates above 7% may still find opportunities if rates dip back toward 6% or below.

The world is more interconnected than ever, and events halfway around the globe can directly affect your monthly mortgage payment. That’s why staying informed matters.
