Mortgage Rates Just Spiked — Here's What You Do Now
Mortgage Rates Just Spiked — Here's What You Do Now
If you got pre-approved for a mortgage even a few weeks ago, your numbers might already be wrong. Rates just jumped, and understanding exactly why it happened, what's driving it, and what you should be doing about it right now is essential — whether you're buying or refinancing.
Let's break this down step by step so you can make a smart, informed decision instead of guessing your way through one of the biggest financial moves of your life.
What Happened: Rates Dipped, Then Reversed Hard
At the very end of February, mortgage rates dipped below six percent for the first time since 2022. That was a big deal. A lot of buyers and homeowners felt like the tide was finally turning in the right direction.
Then on February 28th, the conflict with Iran started. Within about two weeks, rates shot back up — roughly a quarter point higher in a very short window.
A quarter point might not sound like much on paper. But on a typical home purchase, that kind of move can add a couple hundred dollars a month to your payment. Over thirty years, that adds up to serious money.
Why a War on the Other Side of the World Affects Your Mortgage Rate
Here's the simple version. Mortgage rates follow something called the 10-year Treasury yield. Think of the 10-year Treasury as the government's way of borrowing money for ten years.
When investors feel safe, they buy more of these bonds, yields go down, and mortgage rates follow. When investors get nervous — like when a major conflict disrupts the global oil supply — they sell bonds, yields go up, and your mortgage rate goes up with it.
That's exactly what happened here. Oil prices spiked because the Iran conflict is threatening shipping lanes in the Strait of Hormuz, which is where a huge chunk of the world's oil passes through. Higher oil means higher costs to make and ship everything. That makes investors worry about inflation coming back.
When inflation worries go up, bond yields go up. The 10-year Treasury went from under four percent to around 4.35 to 4.39 percent in just a few weeks. That's a significant move. And mortgage rates followed it, tick for tick.
What the Fed's March Decision Really Means for You
This is the part most people miss, and honestly, it's the piece that changes everything if you've been sitting on the sideline waiting for lower rates.
The Fed met on March 18th. They held rates steady — no surprise there. But here's what matters: they still project maybe one rate cut this year. However, they raised their inflation forecast, and Fed Chair Powell essentially said they haven't made as much progress on inflation as they had hoped.
So if you were waiting for mortgage rates to magically drop to five percent, that plan has a serious problem. The market is now only pricing in one small cut, and it might not even come until December.
You can track the Fed's meeting schedule and policy statements directly on the Federal Reserve's website to stay informed on future decisions.
The Real Cost of Waiting: A Client Story
Here's a real example. A client last week was already pre-approved and had found a house she loved. But she said, "Let me wait a month and see if rates come down."
In that one month, rates moved higher — not lower. Her monthly payment on the same house went up meaningfully, and now she's second-guessing the whole purchase.
The point isn't to panic. The point is that waiting for a specific rate is a strategy that almost never works. Nobody — not your lender, not the Fed, not anyone on financial TV — can time the market.
Your 3-Step Action Plan
Here's what you actually control, and these three steps are the difference between people who close on homes and people who watch from the sideline for another year.
Step 1: Check Your Pre-Approval Numbers
Pull up your most recent pre-approval letter or loan estimate. Look at the rate that was quoted. If it was issued more than two or three weeks ago, it's almost certainly outdated. That rate was a snapshot from a different market. You need fresh numbers.
Step 2: Run the Updated Math on Your Budget
Calculate what a higher rate actually means for your monthly budget. Take your loan amount and use any free mortgage calculator online. Punch in a rate that's about a quarter to a half point higher than what you were originally quoted.
If that new payment still fits comfortably within your budget — meaning your total housing costs are under about 28 percent of your gross monthly income — you're still in a strong position. The CFPB's homeownership resources offer helpful guidance on what an affordable payment looks like.
If the new number pushes you past that threshold, that's not a stop sign. It's a yellow light. It means you might need to adjust the price range or look at your down payment strategy.
Step 3: Get on the Phone With Your Lender — To Strategize, Not Shop
This step separates the people who buy homes from the people who keep waiting. Call your lender. But not to shop rates. To strategize.
If you're working with someone who just sends you a rate sheet and says "good luck," that's not a strategy. A good lender will build out multiple scenarios for you — different down payment amounts, different rate levels, what your payment looks like in each scenario, and the actual opportunity cost of waiting versus acting now.

What About Refinancing?
If you're thinking about refinancing, the same rules apply. If you locked in a rate in the high sixes or sevens last year, you might still have room to improve your position even with this recent bump. But don't assume — run the numbers.
A good rule of thumb: if you can drop your rate by at least three quarters of a point and you plan to stay in the home for at least three to four years, a refinance probably makes sense because you'll recoup the closing costs and start saving after that. Fannie Mae's refinance guide is a great resource for understanding your options.
If the math is tight, it might be worth holding your current position and watching how things develop over the next few months.
Why Doing Nothing Is Usually the Most Expensive Decision
A lot of people hear "rates are going up" and they freeze. They do nothing. Uncertainty is uncomfortable, and that reaction makes sense. But doing nothing is a decision too, and it's usually the most expensive one.
The housing market was finally starting to move. Inventory is still tight. Prices haven't dropped. So every month you wait, you're not just dealing with potentially higher rates — you're competing with more buyers who decided to stop waiting.
Home prices continue to hold steady or rise in most markets
Inventory remains historically low, keeping competition strong
Waiting doesn't guarantee lower rates — the mortgage rate forecast remains uncertain
The opportunity cost of not building equity compounds over time
Acknowledge the situation, learn from the data, and make a move. That's how you protect your purchasing power.
Quick Recap
Here's the bottom line on everything covered above:
Mortgage rates jumped because the Iran conflict drove up oil prices and bond yields
The Fed is holding steady with no cuts expected anytime soon and a raised inflation forecast
If you were pre-approved before this spike, your numbers have likely shifted
Pull your documents, run the updated math, and talk to someone who will actually walk you through scenarios — not just send you a rate quote
Frequently Asked Questions
Why did mortgage rates go up so quickly in early 2026?
The Iran conflict that began on February 28th disrupted global oil markets, particularly around the Strait of Hormuz. Higher oil prices reignited inflation fears among investors, which pushed 10-year Treasury yields up from under four percent to around 4.35-4.39 percent in just a few weeks. Mortgage rates track closely with the 10-year Treasury, so they moved higher almost immediately.
Is it still worth buying a home if mortgage rates are rising?
For most buyers, yes. Trying to time the bottom of rates is a strategy that almost never works. If your monthly payment fits within your budget — generally under 28 percent of your gross income for total housing costs — you're in a solid position to buy. Remember, you can always refinance later if rates drop, but you can't go back in time to buy at a lower home price.
How do I know if my pre-approval is still accurate?
If your pre-approval letter or loan estimate was issued more than two to three weeks ago, the rate quoted is likely outdated given how quickly the market has moved. Contact your lender and ask for updated numbers based on current rates so you know exactly where you stand.
When will mortgage rates drop again?
No one can say for certain. The Fed's March 2026 meeting indicated that only one small rate cut may happen this year, and that cut might not come until December. The Fed also raised its inflation forecast, which signals that meaningful rate relief is further out than many hoped. Building your plan around today's rates rather than hoping for lower ones is the safest approach.
Should I refinance now or wait for better rates?
It depends on your current rate and how long you plan to stay in the home. If you can reduce your rate by at least three quarters of a point and plan to stay for at least three to four years, refinancing likely makes sense because you'll recoup closing costs and then benefit from monthly savings. If the numbers are close, it might be worth waiting, but have your lender run the actual scenarios so you're making a data-driven decision.
