The Main Reason Mortgage Rates Are So High




Today’s mortgage rates are top-of-mind for many homebuyers right now. As a result, if you’re thinking about buying for the first time or selling your current house to move into a home that better fits your needs, you may be asking yourself these two questions: 

  1. Why Are Mortgage Rates So High?
  2. When Will Rates Go Back Down?

Here’s context you need to help answer those questions.

1. Why Are Mortgage Rates So High? 

The 30-year fixed-rate mortgage is largely influenced by the supply and demand for mortgage-backed securities (MBS). According to Investopedia: 


“Mortgage-backed securities (MBS) are investment products similar to bonds. Each MBS consists of a bundle of home loans and other real estate debt bought from the banks that issued them . . . The investor who buys a mortgage-backed security is essentially lending money to home buyers.”

Demand for MBS helps determine the spread between the 10-Year Treasury Yield and the 30-year fixed mortgage rate. Historically, the average spread between the two is 1.72 (see chart below):


Last Friday morning, the mortgage rate was 6.85%. That means the spread was 3.2%, which is almost 1.5% over the norm. If the spread was at its historical average, mortgage rates would be 5.37% (3.65% 10-Year Treasury Yield + 1.72 spread).


This large spread is very unusual. As George Ratiu, Chief Economist at Keeping Current Matters (KCM), explains:


“The only times the spread approached or exceeded 300 basis points were during periods of high inflation or economic volatility, like those seen in the early 1980s or the Great Financial Crisis of 2008-09."

The graph below uses historical data to help illustrate this point by showing the few times the spread has increased to 300 basis points or more:


The graph shows how the spread has come down after each peak. The good news is, that means there’s room for mortgage rates to improve today.

So, what’s causing the larger spread and making mortgage rates so high today?

The demand for MBS is heavily influenced by the risks associated with investing in them. Today, that risk is impacted by broader market conditions like inflation and fear of a potential recession, the Fed’s interest rate hikes to try to bring down inflation, headlines that create unnecessarily negative narratives about home prices, and more.

Simply put: when there’s less risk, demand for MBS is high, so mortgage rates will be lower. On the other hand, if there’s more risk with MBS, demand for MBS will be low, and we’ll see higher mortgage rates as a result. Currently, demand for MBS is low, so mortgage rates are high.

2. When Will Rates Go Back Down?

Odeta Kushi, Deputy Chief Economist at First American, answers that question in a recent blog:


“It’s reasonable to assume that the spread and, therefore, mortgage rates will retreat in the second half of the year if the Fed takes its foot off the monetary tightening pedal and provides investors with more certainty. However, it’s unlikely that the spread will return to its historical average of 170 basis points, as some risks are here to stay.”

Bottom Line

The spread will shrink when the fear investors feel is eased. That’ll mean we should see mortgage rates moderate as the year goes on. However, when it comes to forecasting mortgage rates, no one can know for sure exactly what will happen.

Are Big Investors Really Buying Up All the Homes? Here’s the Truth.

By KCM • January 28, 2026
Are Big Investors Really Buying Up All the Homes? Here’s the Truth. It’s hard to scroll online lately without seeing some version of this claim: “Big investors are buying up all the homes.” And honestly, if you’re a homebuyer who’s lost out on a few offers, that idea probably sounds believable. When homes are expensive and competition is tight, it’s easy to assume giant companies are scooping everything up behind the scenes. But here’s the thing: what people assume is happening and what the data actually shows aren’t always the same. Let’s look at what’s really happening with large institutional investors in today’s housing market – because the numbers tell a much different story than the headlines. The Number Most People Won’t See Online Let’s start with the most important stat. According to John Burns Research & Consulting (JBREC), large institutional investors – those that own 100 or more homes – made up just 1.2% of all home purchases in Q3 of 2025 (see graph below): That’s it. Out of every 100 homes sold, only about 1 went to a large institutional investor. And here’s an important point that often gets missed: that level of investor activity is very much in line with historical norms. It’s not unusually high, and it’s actually well below the recent peak of 3.1% back in 2022 – which itself was still a small share of the overall market. So, while it can feel like big investors are everywhere, nationally, they’re a very small part of overall home sales. Why Investor Activity Gets So Much Attention There are two main reasons this topic gets so much attention: Investor activity isn’t spread evenly. Investors are more active in certain markets, which can make competition feel intense for homebuyers in those areas. As Lance Lambert, Co-Founder of ResiClub, explains:“On a national level, “large investors”—those owning at least 100 single-family homes—only own around 1% of total single-family housing stock. That said, in a handful of regional housing markets, institutional and large single-family landlords have a much larger presence. ” Investor is a broad term. Part of what makes the share of purchases bought by investors sound so big is because many headlines lump large Wall Street institutions together with small, local investors (like your neighbor who owns one or two rental homes). But those are very different buyers.In reality, most investors are small, local owners, not massive corporations. And when all investors get grouped together in the headlines as a single stat, it inflates the number and makes it seem like big institutions are dominating the market (even though they’re not). Yes, big investors exist. Yes, they buy homes. But nationally, they’re responsible for a very small share of total purchases – far smaller than most people assume. The bigger challenges around affordability have much more to do with supply, demand, and years of underbuilding than with large institutions competing against everyday buyers. That’s why it’s so important to separate noise from reality, especially if you’re trying to decide if now is the right time to move. Bottom Line If you want to talk through what investor activity actually looks like in our local market, and how it impacts your options (or doesn’t), let’s connect. Sometimes a little context makes all the difference.

Why January Is the Best Time to Kickstart Your 2026 Home Search

By Inner Circle • January 22, 2026
It’s a new year, and if buying a home in 2026 is on your mind, there’s one simple piece of advice worth hearing first: get started now. Not in March. Not in spring. Not “when the weather gets better.” Now. Why? For starters, buying a home takes time. A recent Realtor.com article suggests getting started at least six months before you plan to close. That doesn’t mean starting in January automatically puts you on track for a June closing. In fact, if you get started now, there’s a good chance you could be in a home much sooner than that. On the flip side, even if you don’t plan to move until later in the year, beginning the process early still puts you in a far stronger position when you’re ready to make offers. You’re almost always better off starting sooner rather than later. There’s a lot involved beyond simply finding a house you like. Financial preparation, getting pre-approved for a mortgage, understanding what you can truly afford, getting a handle on the existing inventory, touring homes, writing offers, negotiating terms, and finally closing — all of that takes time. And that’s before factoring in local competition and inventory. But as we head into this new year, there’s another reason starting early matters even more — and it has everything to do with what’s happening in the market right now… It’s Finally a Buyer’s Market in Many Areas… But It Might Not Last One of the biggest reasons to begin in January is where the market stands right now. In many areas, conditions are unusually favorable for buyers — and that’s not something to assume will stick around. According to recent housing market data , there were roughly 37% more sellers than buyers across the U.S. in November 2025, one of the largest gaps on record going back to 2013. A gap that large can give buyers more negotiating power. It often leads to more options, more time to consider choices, and greater leverage when it comes to price, terms, and requests for seller concessions. But that gap can easily close. Many buyers put off looking for a home until the spring market “officially” begins. That’s in quotation marks because there really is no official date for when the spring market begins. But at some point in the next few months, there will likely be a surge of buyers entering the market. When that happens, competition will increase and many of the advantages buyers enjoy early in the year will likely begin to shrink. Buyers who wait may find themselves facing more multiple-offer situations, tighter negotiations, and less room to ask for concessions. Getting started in January doesn’t just give you a head start — it gives you a shot at taking advantage of conditions that may look very different just a few months from now. The First Thing to Do After the First of the Year If you’re even just thinking about buying a home in 2026, the most productive first step after the new year isn’t scrolling listings or heading out to open houses — it’s having a conversation with a local real estate agent. National headlines are helpful for understanding broad trends, but real estate is extremely local. Conditions can vary dramatically from one city to the next, from one neighborhood to another, and even from one price range to another within the same town. An agent can walk you through what inventory looks like right now, how competitive buyers are in your target price range, and whether sellers are negotiating or still holding firm. They can also help you come up with a timeline and strategy based upon your personal situation and the current market conditions. The Takeaway: Buying a home almost always takes longer than people expect. That’s why many experts recommend starting the process at least six months before you plan to move. That doesn’t mean it has to take that long — plenty of buyers find and close on a home much sooner. But it does mean that giving yourself time is rarely a bad idea. Starting as early in the year as possible is always smart, but starting early in 2026 may be even smarter. With roughly 37% more sellers than buyers — the largest gap we’ve seen since 2013 — today’s market is offering buyers opportunities that may not last once more people jump in later this year. Waiting until spring could mean more competition and fewer advantages than buyers see right now. If you’re even thinking about buying in 2026, getting the ball rolling in January can put you in a much stronger position. And the best first step isn’t browsing listings — it’s talking with a local real estate agent who can explain what’s happening in your market, help you set realistic.
