One of the key ways to track mortgage rates is to look at the 10-year bond yield.<\/p>\n

It acts as a bellwether for 30-year fixed mortgage rates because most home loans only last for about a decade.<\/p>\n

They are typically paid off ahead of time, whether it\u2019s due to a home sale, a refinance, or perhaps prepayment via extra payments or a lump sum payoff.<\/p>\n

But because mortgages are riskier than Treasuries that are guaranteed by the government, there is a spread between the two.<\/p>\n

This spread ensures MBS investors get a higher return for taking on the risk of mortgages defaulting or being prepaid.<\/p>\n

And lately this spread has come in tremendously, leading to the lowest mortgage rates in about three years.<\/p>\n

Normal Mortgage Spreads Lead to the Best Mortgage Rates in Three Years<\/h2>\n

\"three<\/p>\n

To come up with the spread, you simply subtract the current 10-year bond yield from the daily mortgage rate (of your choosing).<\/p>\n

For example, if you use Mortgage News Daily\u2019s widely cited 30-year fixed average<\/a> of 6.01% today, and a 10-year yield of 4.18%, we get a spread of 1.83 basis points (bps).<\/p>\n

For context, the historical spread between the 30-year fixed mortgage and 10-year Treasury is about 170 basis points.<\/p>\n

In other words, mortgage spreads are basically back to normal right now.<\/p>\n

The reason mortgage rates were so much higher a year ago (and even higher in late 2023) was due to really wide spreads.<\/p>\n

At one point, the spread was around 325 bps, meaning MBS investors would only buy mortgage-backed securities if they could earn a really sizable return relative to Treasuries.<\/p>\n

One of the reasons was after the Federal Reserve stopped buying trillions in MBS via QE, there was a demand vacuum.<\/p>\n

Essentially, mortgage rates shot higher due to greatly reduced demand and as they did, MBS investors shied away due to increased default risk and also the thought of higher prepayment risk.<\/p>\n

There was less liquidity and at the time, there was a strong opinion that the 8% mortgage rates wouldn\u2019t last very long.<\/p>\n

Chances are they\u2019d be refinanced in short order once rates normalized. And guess what? They were right.<\/p>\n

A lot of 2023- and 2024-vintage mortgages only lasted a year or two before being refinanced to much lower rates.<\/p>\n

MBS investors don\u2019t like when high-rate loans are quickly paid off and exchanged with lower-rate loans.<\/p>\n

So they required a higher spread than normal at the time to compensate for this increased risk.<\/p>\n

Why Are Mortgage Rate Spreads Better Now?<\/h2>\n

Today, mortgage rate spreads are basically back in a totally normal range, which is wild considering they were nearly double that in 2023.<\/p>\n

But now that the MBS market has adjusted and comes to terms with the new post-QE normal of mortgage rates around 6%, there\u2019s a lot more certainty.<\/p>\n

In essence, rates are historically pretty average and there\u2019s the thought they could hang around these general levels for the foreseeable future.<\/p>\n

If that\u2019s the case, there\u2019s the argument that the loans will no longer be paid off rapidly and there\u2019s a sense of stability for MBS investors.<\/p>\n

It\u2019s also a pretty decent yield for MBS investors to earn ~6%, especially if they think they\u2019ll continue to earn 6% for a longer period of time.<\/p>\n

As noted, the 8% rates were very short-lived, so while the higher rates may have seemed attractive, a wider spread was required at the time because many investors probably had a feeling it wouldn\u2019t persist.<\/p>\n

Now that we\u2019ve had mortgage rates remain in a tighter range for the past year and a half, there\u2019s more demand again. Investors have re-entered the picture.<\/p>\n

In addition, as you likely heard, Trump ordered Fannie Mae and Freddie Mac to purchase $200 billion in MBS to bring spreads down even more.<\/p>\n

That\u2019s why they tightened up further over the past couple days, despite the 10-year bond yield barely budging during that time.<\/p>\n

How Do Mortgage Rates Move Even Lower?<\/h2>\n

\"10-yr<\/p>\n

While the news on spreads is a positive, it also means we likely won\u2019t get much more relief via spreads.<\/p>\n

After all, they are back to normal. So the only way to get mortgage rates even lower (outside another round of QE) is via a lower 10-year bond yield.<\/p>\n

Remember, it serves as a bellwether, so if the 10-year comes down, 30-year fixed mortgage rates can come down too.<\/p>\n

But in order for that to happen, you either need inflation to cool or you need labor to worsen.<\/p>\n

You could have both those things happen concurrently, which is kind of what\u2019s been happening lately.<\/p>\n

The spreads were a major reason why mortgage rates got markedly better, but we can also thank lower 10-year bond yields too.<\/p>\n

The 10-year yield<\/a> was priced at about 4.65% a year ago and is nearly 50 basis points lower today.<\/p>\n

So mortgage rates are about 1.25% lower today (7.25% vs. 6%) thanks to both a lower 10-year bond yield and tighter spreads.<\/p>\n

But if spreads are normal, you look to bond yields if you want even lower rates. As noted, that can happen with a slowing economy, whether it\u2019s disinflation or higher unemployment.<\/p>\n

The trick is threading that needle where inflation cools and labor perhaps eases without a recession, so we don\u2019t get lower mortgage rates but a worse off economy (and by extension housing market).<\/p>\n
