Iran War Keeps Mortgage Rates Stuck Above 6% as Spring Homebuying Season Hangs in the Balance

For borrowers sitting on the sidelines of the housing market, today’s mortgage rate landscape offers a mixed and heavily geopolitics-influenced picture. The current average 30-year fixed mortgage interest rate is 6.23% as of Thursday, March 12, 2026, according to Bankrate’s latest survey of the nation’s largest lenders. For homeowners weighing refinancing, the average 30-year fixed refinance interest rate stands at 6.62%, while the average 15-year refinance interest rate sits at 5.92%. The national average 30-year fixed mortgage APR, which incorporates lender fees on top of the headline rate, is 6.29%.

Those numbers would look very different — and considerably more encouraging — if you had checked them two weeks ago. Rates had briefly dipped below 6% for the first time since 2022, crossing what many economists describe as a key psychological threshold. That window slammed shut almost immediately when the United States and Israel launched military operations against Iran on February 28, reigniting inflation fears through an oil shock and pushing Treasury yields — and with them, mortgage rates — sharply higher. What happened to mortgage rates over the past two weeks is a case study in how abruptly geopolitical shocks can rewrite the affordability calculus for millions of American households.

How the War in Iran Reversed a Historic Rate Milestone

The timing of the Iran conflict could hardly have been worse for the housing market’s momentum. Mortgage rates briefly touched 5.98% the week ending February 27 — the first sub-6% reading since 2022 — generating genuine excitement among housing economists and prospective buyers who had been waiting for exactly this kind of signal. Within days, those gains were erased.

Mortgage rates jumped back above 6% in the immediate aftermath of the US-Israel strikes, driven by a spike in oil prices and the resulting surge in inflation expectations. The mechanism is well-established: mortgage rates track closely with the yield on the 10-year US Treasury note, which investors bid upward when they price in higher future inflation. By Thursday, March 12, the 10-year Treasury yield has climbed to approximately 4.19%, up from 3.96% on February 27, the day before the conflict began — a move of more than 23 basis points in under two weeks, and one that has fed almost directly into the mortgage rates consumers are seeing today.

“Despite growing economic data showing a weakening U.S. economy, the ongoing conflict in Iran is keeping mortgage rates north of 6%,” said Jeff DerGurahian, chief investment officer and head economist at loanDepot, quoted in Bankrate’s March analysis. “Without the geopolitical tensions, we would likely be seeing a 10-year Treasury well south of 4%, with mortgage rates in the high 5s.”

The conflict has also introduced a new dimension to the normal dynamics of war and bond markets. Typically, armed conflict drives investors toward the perceived safety of US government bonds, pushing yields lower and pulling mortgage rates down with them. But this time, the Iran war has done the opposite. The closure of the Strait of Hormuz to commercial tanker traffic has triggered an oil supply shock large enough to raise inflation expectations faster than safe-haven demand can push yields lower. Bonds are being sold, not bought, because investors are more worried about inflationary erosion of returns than about financial system instability.

Today’s Full Rate Picture: Purchase and Refinance

Here is a comprehensive view of where rates stand across all major product types on March 12, 2026, according to Bankrate’s national survey:

The 30-year fixed purchase rate averages 6.23% (APR: 6.29%). This is the most widely used mortgage product in the United States and the rate that most first-time buyers will encounter. A year ago, Freddie Mac recorded the 30-year fixed rate at 6.63%, meaning that despite the post-Iran bounce, borrowers today are still financing at a materially lower cost than they were twelve months ago.

The 15-year fixed purchase rate averages approximately 5.43–5.48% based on Freddie Mac’s most recent weekly survey, versus 5.79% a year ago. This product remains attractive for refinancers and move-up buyers who can manage the higher monthly payment in exchange for dramatically reduced total interest over the life of the loan.

For refinancing, the average 30-year fixed refinance rate is 6.62% — notably higher than the purchase rate, a spread that reflects the additional lender risk associated with refinance transactions. The 15-year fixed refinance rate averages 5.92%.

Adjustable-rate mortgage products are also available at slightly lower initial rates — the 5/1 ARM averages approximately 6.01% and the 7/1 ARM sits near 5.82% — though in the current environment of elevated rate uncertainty, the appeal of locking in a fixed rate has risen. Historically, ARMs become more popular when the initial rate advantage over fixed products is large; with that gap relatively modest today, most borrowers continue to gravitate toward fixed-rate loans.

The Treasury-Mortgage Spread: A Rare Bright Spot

One structural feature of the current rate environment deserves attention from borrowers: the spread between mortgage rates and the 10-year Treasury yield is significantly narrower than it was during the most painful stretch of 2023, when the spread ballooned to historic levels and amplified the impact of every basis-point move in Treasury yields.

Historically, mortgage rates have run roughly one to two percentage points above the 10-year Treasury yield, according to the Brookings Institution. Today’s spread of approximately 1.93–2.00 percentage points is close to the upper end of that historical range, but well below the abnormal peak of 3.00% seen in late 2023. HousingWire analyst Logan Mohtashami noted that “mortgage spreads are under 2%” — a positive development that has helped keep rates from climbing even higher in response to the jump in Treasury yields. Had spreads matched their 2023 peak levels, today’s mortgage rates would be approximately 1.20 percentage points higher — meaning the 30-year rate would be closer to 7.5% rather than 6.23%.

Why does the spread matter? Because even as geopolitical shocks push Treasury yields around, the normalisation of mortgage spreads provides a buffer. A narrower spread means mortgage rates are more directly connected to underlying Treasury market moves, rather than amplified by them. That is moderately good news for borrowers in the current environment.

The Housing Market: Affordability Improves, Demand Remains Cautious

Against the backdrop of persistently elevated rates, the latest housing market data reveals a picture of gradual improvement interrupted by war-driven uncertainty. Existing-home sales rose 1.7% month-over-month in February to a seasonally adjusted annual rate of 4.09 million, according to the National Association of Realtors (NAR) — exceeding market expectations of 3.89 million and partially recovering from January’s weather-affected 8.4% plunge.

The median existing-home price reached $398,000 in February, up a modest 0.3% from $396,800 a year earlier — the 32nd consecutive month of year-over-year price increases, though at a pace that has slowed considerably from the torrid 10%-plus gains of 2021–2022. Inventory stood at a 3.8-month supply, unchanged from January but up from 3.6 months a year ago. A balanced market is generally considered to have 5–6 months of supply, so inventory remains tight by historical standards even as conditions improve at the margin.

The affordability picture has been quietly brightening for most of the past year, however. NAR’s Housing Affordability Index rose to 117.6 in February — up from 117.1 in January and a full 14.5 points above the 103.1 reading from a year ago, reaching its highest level since March 2022. An index reading above 100 means the median-income household can qualify for the median-priced home; at 117.6, there is meaningful headroom above that threshold, reflecting both lower rates versus the 2023–2024 peak and wage growth that has outpaced home price increases. “Wage growth is now outpacing home price growth by almost four percentage points,” NAR Chief Economist Lawrence Yun said.

Zillow senior economist Kara Ng captured the current market tension succinctly: “Mortgage rates briefly fell below 6% before an oil shock reversed them. Buying power is up about $30,000 compared to this time last year, as mortgage rates fell from the high 6% range to the low 6% range. Households that did not buy or refinance a home during the mortgage rate dip might have missed a flash sale, but can still buy at a discount.”

The War Risk to the Housing Market: How Much Could Rates Rise?

The most important variable for the spring 2026 housing market — traditionally the busiest selling season of the year — is whether Iran-driven inflation materialises in a sustained way or proves transitory.

Redfin chief economist Daryl Fairweather identified the core dilemma: “Fear of higher inflation because of higher oil prices tends to push rates up, but fear about global stability and economic growth tends to push rates down.” So far, inflation fears are winning the argument in the bond market, as the dramatic oil price surge and Strait of Hormuz closure have set off a round of inflation repricing. Redfin economist Chen Zhao noted that “mortgage rates are unlikely to fall as they usually would in response to data like this because the escalating Iranian conflict is dominating headlines, with oil prices spiking.”

Goldman Sachs economists told clients that inflation could snap back to 3% this year if the war drags on and oil prices keep rising, compared to their earlier prediction that inflation would ease to 2% by year-end. Every $10-per-barrel sustained increase in oil prices costs the average US household roughly $450 per year, according to Moody’s economist Mark Zandi — a meaningful drag on disposable income at a moment when consumers are also navigating the lagged effects of tariff-driven price increases.

The key threshold to watch for housing is the 7% mortgage rate level. HousingWire’s Mohtashami noted that “every time rates head toward 7% or higher, the sales demand curve turns negative and the housing market stalls.” Today’s 6.23% average is a safe distance from that threshold, but a continued escalation of the Iran conflict — particularly if it drives oil materially above the current $87 per barrel — could accelerate the pace of Treasury yield increases and push mortgage rates meaningfully higher in coming weeks.

The Federal Reserve’s March meeting, taking place next week, is universally expected to produce no change in the federal funds rate. The Fed has held its benchmark rate steady at 3.50–3.75% since January. Fannie Mae’s 2026 Housing Forecast projects that mortgage rates will sit at 6% for most of 2026 and 2027 — a forecast that appears optimistic given the current geopolitical environment, though not implausible if the Iran conflict resolves and oil prices normalise.

Should You Buy, Wait, or Refinance Now?

For prospective buyers, the tactical question is whether today’s 6.23% rate represents a reasonable entry point or whether waiting for a return to sub-6% rates is the better play. The honest answer depends entirely on your personal financial position and timeline — but the structural data suggests that waiting carries its own risks.

Home prices, while growing slowly, are still growing: the median existing-home price has risen for 32 consecutive months on a year-over-year basis. The brief window below 6% that opened in late February suggests that sub-6% rates are achievable when macroeconomic conditions align — but events like the Iran conflict demonstrate that such windows can close in a matter of days. Borrowers who can afford today’s payments and plan to hold for seven or more years have a reasonable case for acting now, particularly given that affordability is at its best level since March 2022.

For existing homeowners considering refinancing, the calculus requires comparing today’s offered rate against what you are currently paying. The average 30-year fixed refinance rate of 6.62% is higher than the current purchase rate, as is standard in the market. Homeowners who locked in rates above 7% in 2023 or 2024 could still achieve meaningful interest savings by refinancing today, even at 6.62%. Those who secured rates in the 6.0–6.5% range during 2025 would benefit from a more significant rate drop before the numbers make sense.

The most critical piece of advice for any borrower entering the market right now is straightforward: shop aggressively across multiple lenders. LendingTree data shows that shopping with three to five mortgage lenders can produce meaningfully lower rates, potentially saving thousands of dollars over a 30-year term. Bankrate’s Mortgage Rate Variability Index currently reads 6 out of 10 — indicating some degree of dispersion in lender offers — which means the difference between the first rate you’re quoted and the best available rate could be substantial. The average 30-year fixed APR of 6.29% on Bankrate’s platform encompasses a range of offers from different lenders, and the best offers are typically available only to borrowers who invest the time to compare.

What Drives Your Individual Rate: The Key Variables

National averages provide useful context, but the rate any individual borrower receives will be shaped by several personal financial factors that lenders evaluate closely.

Credit score is the single most influential factor. The best mortgage rates are generally reserved for borrowers with FICO scores of 780 or above. A score between 700 and 779 typically adds 0.25–0.50 percentage points to the offered rate, while scores below 700 can add a full percentage point or more. Before applying, checking your credit report and addressing any errors or delinquencies is one of the highest-return actions you can take.

Loan-to-value ratio and down payment matter significantly. Lenders price risk, and a larger down payment reduces the lender’s exposure in the event of default. Borrowers who put down 20% generally receive better rates and avoid private mortgage insurance, which adds to the effective monthly cost of lower-down-payment loans. FHA loans are available with as little as 3.5% down for borrowers with credit scores of 580 or above, but carry both upfront and annual mortgage insurance premiums.

Loan type and term also affect pricing. Veterans may be eligible for VA loan rates, which currently average approximately 5.52% on a 30-year basis — meaningfully below the conventional rate. FHA loans typically carry rates in the 5.75–6.00% range for well-qualified borrowers. The 15-year fixed rate, currently averaging approximately 5.43%, offers significant lifetime interest savings compared to the 30-year product — but the higher monthly payment requires that the borrower’s income and cash flow can support it.

Mortgage points — upfront fees equal to 1% of the loan amount — allow borrowers to purchase a lower interest rate. Whether buying points makes sense depends on how long you plan to stay in the home: points typically take four to seven years to break even, making them most attractive for long-term homeowners.

The Outlook: Rate Path Depends on the Strait

The single most important variable for mortgage rates over the next three to six months is not the Federal Reserve, not inflation data, and not the jobs market. It is whether oil continues to flow through the Strait of Hormuz.

If a ceasefire or diplomatic resolution leads to a reopening of the Strait and a sustained decline in oil prices, the inflation fear that currently has yields elevated would dissipate. Treasury yields would likely decline, mortgage rates would follow, and the brief sub-6% window of late February could reopen and persist. In that scenario, the housing market would likely see a rapid recovery in activity, as the combination of improved affordability and pent-up demand from years of rate-constrained buyers would produce a surge in both sales and refinancing activity.

If the conflict persists and oil prices remain elevated or push higher, the opposite scenario unfolds. The 10-year Treasury yield, currently at 4.19%, could move toward 4.5% or higher. Mortgage rates would likely track to 6.5–6.75%, weighing on the spring selling season and potentially reversing several months of affordability gains. The Federal Reserve would face a stagflationary dilemma — growth slowing while inflation rises — with no clean policy response available.

For now, borrowers should operate on the assumption that today’s 6.23% rate is the market as it actually exists, not the market as it was two weeks ago or might be in six months. Whether that rate represents a good deal depends on your individual financial circumstances, your timeline, and your read of a geopolitical situation that could resolve quickly or drag on through the spring and summer. What is certain is that the window between today’s rates and the 7% danger zone for housing demand remains open — and that the spring 2026 homebuying season will be defined by whether that window stays open long enough for buyers to walk through it.
