'Another hit to consumers’ pocketbooks': Trump’s EU tariff threats sent mortgage rates higher. Here’s how it could make home buying even more pricey

So what caused the sudden spike? It wasn’t driven by inflation data or Federal Reserve policy; instead, markets got spooked after President Donald Trump floated the idea of new tariffs on imports from eight European countries — including Denmark, France, Germany and the U.K. — starting February 1.

That kind of geopolitical tension tends to make investors nervous. Here’s how these proposed tariffs affect investors and potential homebuyers.

How market turns affect homebuyers

Trump said the tariffs would begin at 10% and climb as high as 25% by June if those countries continued to push back on his proposal for the U.S. to take control of Greenland.

Investors reacted quickly in the bond market. The yield on the 10-year Treasury note, which mortgage rates tend to follow pretty closely, jumped to around 4.25% (2).

At the same time, investors were dealing with turbulence overseas, including a selloff in Japanese government bonds tied to new spending plans there. It was another reminder that mortgage rates don’t just respond to U.S. housing policy, global events can move them fast, too.

“This is a similar pattern to what we saw last spring, when fears over tariffs specifically and geopolitical risk in general caused bond yields to jump and then remain elevated,” Jake Krimmel, a senior economist at Realtor.com, told MarketWatch.

Adding to the confusion, the tariff threats didn’t stick around for long. Within days, Trump signaled he was open to talks and appeared to ease off the idea of immediate tariffs, which helped calm markets somewhat (3).

For people trying to buy a home, the constant back-and-forth can feel impossible to keep up with. Rates drop on one headline, spike on the next, settle down, and then jump again when new developments pop up.

It can be especially frustrating at a moment when affordability is already stretched thin. Home prices remain near record highs, with the median existing-home price reaching $414,400 in 2025 (4).

The latest jump in rates also risks cooling momentum that had been building. Applications surged when rates fell after Trump announced plans for the government to buy $200 billion in mortgage-backed securities, which helped pull rates lower.

But as Krimmel warned, renewed trade tensions could still come back to bite consumers through higher borrowing costs and shakier confidence about the economy.

“For the housing market in general, reigniting the trade war risks another hit to consumers’ pocketbooks, and a resurgence of geopolitical uncertainty means consumer confidence will likely dip, too,” Krimmel said (2).

In other words: even if rates calm down again soon, there’s no guarantee they’ll stay there.

When monitoring mortgage rates, focus on what you can control

When the political landscape is chaotic, headlines can cause mortgage rates to move at the drop of a hat.

The good news is you don’t need to try to predict the next headline to make smart housing decisions. Here are some ways you can stay grounded and protect your affordability, no matter what’s happening in Washington, D.C.:

1. Get pre-approved, not just pre-qualified

A full pre-approval lets you move quickly when rates dip, even briefly. In volatile markets, timing matters (5).

2. Work on your credit score

Even a small improvement can save meaningful dollars off your monthly payment. Pay down balances, avoid new debt and look out for any errors on your credit report (6).

3. Be flexible on location and size

Looking at smaller homes or nearby neighborhoods can reduce your price and can soften the impact of rate swings.

4. Save for a larger down payment
