Mortgage Rates Climb as Iran Conflict Jolts Oil and Bond Markets
Mortgage rates moved higher in early March after geopolitical tensions tied to the war involving Iran pushed oil prices and Treasury yields upward. Freddie Mac said the average 30-year fixed mortgage rate rose to 6.11% on March 12, 2026, up from 5.98% on February 26 and 6.00% on March 5. The average 15-year fixed rate increased to 5.50%. Even with that move, rates remain below year-ago levels, when the 30-year averaged 6.65%. The basic chain reaction is familiar: war risk can lift oil prices, higher oil can worsen inflation expectations, and higher inflation expectations can push Treasury yields and mortgage rates higher. At the same time, flight-to-safety buying in bonds can sometimes pull yields lower, which is why borrowers should expect volatility rather than a straight-line move in one direction. For homebuyers and refinancers, the practical takeaway is simple: shop aggressively, monitor rate swings closely, and be prepared to lock when pricing briefly improves.

Why Mortgage Rates Are Reacting
Mortgage rates do not move directly with the Federal Reserve’s policy rate on a day-to-day basis. Instead, they tend to track the broader bond market, especially the 10-year Treasury yield, because mortgage-backed securities compete with Treasurys for investor demand. Recent geopolitical turmoil has unsettled that market. The Associated Press reported that as of March 12, 2026, the 10-year Treasury yield had moved up to 4.25%, helping send mortgage rates back above 6%.
Oil is part of that story. Reuters reported that the United States announced a release of 172 million barrels from the Strategic Petroleum Reserve on March 11 in response to oil-market stress tied to the conflict, while the International Energy Agency coordinated a larger release with other countries. That kind of emergency action underscores how seriously policymakers are taking the inflation risk from higher energy prices.
When oil jumps, investors often worry that transportation, manufacturing, and consumer costs will rise with it. That can increase expected inflation and make investors demand higher yields. But there is a competing force: during periods of fear, investors also pile into safer assets like Treasurys. That tug-of-war can create fast swings in mortgage pricing rather than a stable trend. Reuters, AP, and Freddie Mac data all point to that same conclusion right now: volatility is back.
The Current Mortgage Rate Picture
The latest Freddie Mac survey shows:
Loan Type | March 12, 2026 | March 5, 2026 | February 26, 2026 | Year Ago |
|---|---|---|---|---|
30-year fixed | 6.11% | 6.00% | 5.98% | 6.65% |
15-year fixed | 5.50% | 5.43% | 5.44% | 5.80% |

That matters because buyers who were waiting for a sustained break below 6% just got a reminder that mortgage rates can reverse quickly when global risks flare up.
Why the U.S. Is Better Positioned Than in Past Oil Shocks
The U.S. economy is still exposed to oil shocks, but it is less dependent on imports than it was during earlier crises. The U.S. Energy Information Administration says the country imported about 8.33 million barrels per day of petroleum in 2022, while total petroleum consumption averaged about 20.28 million barrels per day. EIA also notes the U.S. became a net annual petroleum exporter in 2020 and remained one in 2022.
That does not make the housing market immune, but it does suggest today’s rate shock may not have the same structural force as older oil crises. The risk for borrowers is less about a permanent surge and more about sudden repricing tied to headlines, supply disruptions, and inflation expectations.
What Borrowers Should Do Now
1. Be ready to lock quickly
If rates improve and the payment works for your budget, locking can remove a major source of uncertainty. In a volatile market, the best rate of the week can disappear fast.
2. Shop multiple lenders
Even when headline averages move up, lender-to-lender pricing can vary meaningfully. Borrowers should compare at least three to five quotes, including banks, credit unions, mortgage brokers, and online lenders.
3. Protect your credit profile
Your credit score still has a large impact on the rate you receive. Lower balances, on-time payments, and avoiding new debt before closing can help preserve pricing.
4. Consider a shorter term if cash flow allows
Freddie Mac’s latest data show the 15-year fixed average at 5.50%, notably below the 30-year average. The tradeoff is a higher monthly payment, but borrowers can save substantially on interest over time.
5. Focus on payment, not headlines
Trying to perfectly time rates is rarely realistic. What matters most is whether the home, monthly payment, and long-term plan fit your finances.
What Happens Next
The near-term direction for mortgage rates depends on three moving pieces: energy prices, Treasury yields, and incoming inflation data. If oil stabilizes and bond markets calm down, rates could ease again. If the conflict broadens or energy infrastructure remains under threat, rates could stay jumpy or move higher. Reuters and AP both indicate that policymakers and markets are treating the energy shock as serious, but not yet uncontrollable.
For housing, that likely means a spring market defined by hesitation and brief windows of opportunity. Buyers who are prepared with preapproval, strong credit, and a clear lock strategy will be in the best position to act when pricing improves.
FAQ
Why are mortgage rates rising because of the Iran war?
Because war-related energy disruptions can push oil prices higher, which can raise inflation expectations and Treasury yields. Mortgage rates often follow those bond-market moves.
What is the average 30-year mortgage rate right now?
Freddie Mac reported the average 30-year fixed mortgage rate at 6.11% on March 12, 2026.
Are rates still lower than a year ago?
Yes. The 30-year fixed averaged 6.65% a year ago, versus 6.11% now.
Should buyers lock their mortgage rate now?
Borrowers who find a payment that fits their budget should strongly consider locking, especially in a volatile market. No one can consistently predict the exact bottom.
Are 15-year mortgage rates lower than 30-year rates?
Yes. Freddie Mac reported the average 15-year fixed rate at 5.50%, below the 6.11% average for a 30-year fixed loan.
Bottom Line
Mortgage rates are no longer drifting lower in a calm, orderly way. They are reacting to geopolitics, oil, and bond-market nerves in real time. That does not mean buyers should panic. It means they should be prepared.
The borrowers who win in this market will not be the ones who guess every rate move correctly. They will be the ones who understand their budget, compare lenders carefully, and lock when the opportunity is there.
