If you’re shopping for a home in Central Oregon and trying to figure out where mortgage rates are headed, stop watching the Fed funds rate and start watching the 10-year Treasury yield. It’s the single most useful indicator for predicting mortgage rate movement, and understanding the relationship will make you a better-informed buyer.
The Basics: Why Treasury Yields Matter
Mortgage-backed securities (the bonds that fund most home loans) compete with Treasury bonds for investor money. When Treasury yields rise, mortgage rates rise to stay competitive. When Treasury yields fall, mortgage rates follow. The relationship isn’t perfect, but it’s the strongest correlation in housing finance.
Federal Reserve policy drives roughly 65-75% of Treasury yield movement. The rest comes from inflation expectations, global capital flows, and market sentiment. When you hear that the Fed “controls” mortgage rates, that’s an oversimplification, but it’s not entirely wrong either.
The Spread: Where the Real Story Lives
The difference between the 10-year Treasury yield and the average 30-year mortgage rate is called the spread. Historically, this spread has averaged about 170 basis points (1.7 percentage points). During periods of market stress, it widens. During calm periods, it narrows.
Here’s where it gets interesting for today’s buyers. In 2023, the spread blew out to over 300 basis points, which is why mortgage rates hit 8% even though Treasury yields peaked around 5%. That spread has been compressing. As of early 2026, it’s running around 220-240 basis points, still above the historical average but well below the panic levels of 2023.
What this means: even if Treasury yields stay exactly where they are, further spread compression could push mortgage rates lower. If the spread returns to its historical average of 170 basis points with a Treasury yield of 4.1%, you’d be looking at mortgage rates around 5.8%. That’s meaningful for Central Oregon buyers.
Current Yield Environment
The 10-year Treasury has been trading in a range of roughly 3.80% to 4.60% over the past several months. That’s a wide band, and it reflects genuine uncertainty about the economic outlook. When recession fears spike (weak jobs reports, declining manufacturing data), yields drop toward the low end. When inflation data comes in hot or the economy shows resilience, yields push higher.
At 4.10% (roughly where we are in March 2026), and with the current spread, mortgage rates sit near 6.31%. Here’s a quick reference for how yields translate to rates at today’s spread:
- Treasury at 3.60%: Mortgage rates around 5.80-6.00%
- Treasury at 4.00%: Mortgage rates around 6.20-6.40%
- Treasury at 4.40%: Mortgage rates around 6.60-6.80%
- Treasury at 4.80%: Mortgage rates around 7.00-7.20%
For Central Oregon, where the median home price in Deschutes County is around $615,000, the difference between a 6% rate and a 7% rate on a $500,000 loan is approximately $330 per month. Over 30 years, that’s nearly $119,000. Treasury yields are not abstract financial data; they directly affect what you can afford.
What Moves Treasury Yields
Economic Data
Monthly jobs reports, inflation readings (CPI and PCE), GDP growth, and consumer spending data all move yields. Stronger-than-expected economic data pushes yields up. Weaker data pushes them down. If you want to understand short-term rate movements, the Bureau of Labor Statistics release calendar is your friend.
Fed Policy Signals
The Fed doesn’t set Treasury yields directly, but its forward guidance heavily influences them. When the Fed signals rate cuts are coming, the bond market typically prices that in before the cuts actually happen, pushing yields (and mortgage rates) lower. When the Fed signals it will hold rates higher for longer, yields rise.
Global Capital Flows
U.S. Treasuries are considered the safest investment on the planet. During global uncertainty, money flows into Treasuries (pushing yields down). During periods of global stability, money flows into riskier assets (pushing yields up). This is why geopolitical events can affect your mortgage rate.
What This Means for Central Oregon Buyers
The practical takeaway is straightforward. If Treasury yields drop below 3.80% and stay there, expect mortgage rates to approach 6% or lower, which would significantly boost buyer demand across Central Oregon. More buyers means more competition and potentially higher prices.
If yields push above 4.60%, expect rates back near 7%, which historically weakens housing activity. Fewer buyers, slower sales, and more negotiating leverage for those who remain in the market.
The current range of 3.80-4.60% produces mortgage rates in the zone where the market functions but isn’t overheated. It’s frankly not a bad environment for buying if you find the right property, because you’re not competing against the frenzy that sub-6% rates would unleash.
A Note on Timing
Trying to time the bottom of interest rates is like trying to time the stock market. Some people get lucky, but the math shows that most people who wait end up paying more for a home to save less on their rate. If the numbers work for your budget today, and you find a property you want to live in, the rate environment is reasonable.
You can always refinance if rates drop meaningfully. You can’t always buy the house you want if prices rise while you’re waiting for a rate that may not materialize.
