Are Treasury Yields Approaching a Turning Point? What It Means for Mortgage Rates

Market Signal: The Risk-Reward Calculation Is Changing

At some point, Treasury yields get high enough that investors start reconsidering how much additional risk they need to take.

I think we may be getting to that point.

Last week, the 10-year Treasury tested the 5.35% level, territory we haven't seen since 2002.

While rising Treasury yields have continued to put pressure on mortgage rates, there's another side to this that deserves attention.

When the so-called "risk-free rate" reaches these levels, the relative attractiveness of other investments begins to change.

Institutional investors, pension funds, insurance companies, and foreign buyers can earn meaningful yields from U.S. government securities without assuming the additional credit risk of corporate bonds or the volatility associated with equities.

That doesn't eliminate interest rate or inflation risk. But it changes how investors evaluate the additional return they're being offered for taking on more risk.

And last week's Treasury auction may have provided some evidence of that shift.

Strong Treasury Demand at Elevated Yields

On October 7, the Treasury's $39 billion 10-year note auction attracted strong demand, with a bid-to-cover ratio of approximately 2.77.

Indirect bidders, a category that includes foreign institutions and other investors, accounted for more than 80% of the allocation.

That is meaningful demand at a time when Treasury yields have been moving higher.

Now, one auction doesn't establish a trend. And it doesn't necessarily mean investors are selling equities or corporate bonds to purchase Treasuries.

But it does suggest buyers are willing to commit capital at these yield levels.

If that demand continues, it could begin providing some resistance to further increases in yields.

What's Driving Treasury Yields Higher?

There are still several forces working in the opposite direction.

Inflation remains a significant concern, particularly with energy prices and geopolitical developments creating uncertainty about future price pressures.

Higher energy costs can work their way through transportation, manufacturing, and consumer prices, making it more difficult for inflation to return to the Federal Reserve's target.

At the same time, markets continue to evaluate the likelihood of additional Fed tightening.

As of late last week, the CME FedWatch Tool indicated a relatively low probability of an October rate hike but a considerably higher probability of additional tightening by December.

That creates an interesting situation.

Investors may be increasingly attracted to Treasury yields at current levels, while inflation expectations and monetary policy uncertainty continue pushing those same yields higher.

Which force ultimately dominates will have important implications for mortgage rates.

Mortgage Rates and the Importance of Spreads

Freddie Mac's October 8 survey reported a national average 30-year fixed mortgage rate of 7.40%, marking another weekly increase.

Although mortgage rates generally move in the same direction as the 10-year Treasury, the relationship isn't one-to-one.

The difference between Treasury yields and mortgage rates is influenced by mortgage-backed security pricing, prepayment risk, liquidity, and investor demand.

In 2023, those spreads became unusually wide, contributing to mortgage rates above 8%.

Since then, spreads have narrowed toward more historically typical levels.

That has helped moderate mortgage rates relative to where they might otherwise be with Treasury yields this elevated.

There's also another dynamic worth watching.

As mortgage rates rise, fewer homeowners have an incentive to refinance. That extends the expected duration of existing mortgage-backed securities.

Institutional investors may respond by adjusting their interest rate hedges, which can create additional selling pressure in the Treasury market.

In other words, rising yields can sometimes reinforce the very market conditions that pushed them higher in the first place.

Mortgage Rate Outlook: Why 5.35% Matters

The 5.35% level on the 10-year Treasury is what I'm watching most closely.

From a technical perspective, this is an important resistance area.

If institutional and foreign demand continues emerging around these levels, it could provide enough buying support to slow or stabilize the recent increase in yields.

But there's another possibility.

If the 10-year breaks decisively above 5.35% and holds there, we could see another leg higher in Treasury yields.

That would likely put additional upward pressure on mortgage rates, particularly if mortgage-backed security spreads also begin widening.

This is why I'm not ready to conclude that we've seen the peak in rates.

Strong demand is encouraging, but it needs to be sustained.

What to Watch Next

This week's inflation data could help determine whether the Treasury market finds some stability or continues moving higher.

The September Consumer Price Index and Producer Price Index reports will provide additional insight into whether inflation pressures are broadening beyond energy.

I'll be paying particular attention to core inflation, Treasury demand, and how yields react to the economic data.

Sometimes the market's reaction tells us more than the headline number itself.

If yields continue testing 5.35% but fail to break higher, that could strengthen the argument that investors are finding value at current levels.

A sustained move above that resistance area would suggest the opposite.

Colorado Housing Perspective

For buyers and homeowners across Denver, Broomfield, Boulder, and the Front Range, the recent increase in mortgage rates continues to affect affordability.

Higher borrowing costs reduce purchasing power and can make monthly payments more challenging.

But we're also seeing a housing market where buyers may have more negotiating leverage than they did during periods of intense competition.

September data from the Denver Metro Association of Realtors showed closed sales declining approximately 21% from a year earlier, while inventory conditions provided buyers with additional choices.

That doesn't mean every neighborhood or price range is experiencing the same conditions.

It does mean financing costs need to be considered alongside purchase prices, seller concessions, and longer-term ownership plans.

Professional Takeaway

The bond market is approaching an interesting point.

Treasury yields are high enough to attract meaningful investor demand, but inflation and geopolitical uncertainty continue creating pressure in the opposite direction.

For me, the important question isn't whether we've seen the peak in rates.

It's whether we're beginning to see enough demand in the Treasury market to establish some stability, or whether the next move is another breakout to the upside.
