Track the Why, not the what: 🗓️December 5, 2025 ~ Alert📢
Today’s Mortgage Rates: What’s driving the change isn’t just about the daily number that pops up. It’s more about the WHY that caused the numbers to move. 💡Understanding the economic forces, Fed policy shifts, and bond market trends behind rate changes helps you make smarter, more confident decisions with your money. Each day, I break down the “WHY” behind the moves. It goes far beyond the headlines, revealing the deeper story of what drives rates and affects your monthly payment. 🧠💲
🚨 Morning Predictions ~ All 👀 Are on the Bond Market & Securities ~ 12-5-2025 @ 10:00🕙
📉 The Fed’s Math vs. Wall Street’s Story. That bump means mortgage rates will push higher today, unless the FHFA Fed desk steps in again. We’re starting the day with the 10-year Treasury yield up by 0.030 📈, now at 4.117% as of 9:00 AM. The real question this morning is: Will the FHFA compress the MBS gap for a fourth straight day to keep mortgage rates from rising too high? It would appear the Fed desk has baked in an interest rate cut even though Wall Street hasn’t. 🤔Based on the Federal Reserve Report, my crystal ball says the Federal Reserve is setting up for another rate cut 🔮.
🔧 Why This Week Feels Messy
The last time they went this hard was September and October, forcing rates down to 6.13%—twice—right before a rate cut. This week? They’re right back in the market, smoothing out volatility. And agencies are holding mortgage rates steady while yields try to climb. The FHFA has been compressing the gap for 3 straight days. In November, they let the math run because there was no Fed meeting. That tells us: The bond market and the Fed’s script are completely out of sync. ⚡
What’s Driving the Volatility Today
📊 The Fed’s Math Points to a Cut🧨 Unemployment is currently rising at 4.4%. The Federal Reserve projection for the end of 2025: 4.7%. A rising jobless rate signals a cooling labor market, easing wage pressure, and supporting lower inflation. Now we have great news. The Federal Reserve is now calculating the pass-through rates of tariffs on inflation. The Fed Reserve calculation—using June–August trends of .5 —shows PCE YoY inflation near 2.241% once tariff noise is removed. That’s precisely what the Fed looks at: Is demand cooling? Yes. This gives them cover to cut rates, even if headline PCE is still above 2.5%.
More Reasons for Volatility ⤵️
1️⃣ Conflicting Jobs Signals
Job growth is slowing, revisions keep rolling in, and the market can’t get a clean read. Powell already said jobs now outrank inflation, so every labor datapoint is triggering knee-jerk reactions in the bond market.
2️⃣ Bond Traders Don’t Trust the Data
Investors still see major cracks in government reports. When trust drops, volatility rises. Traders pull back from Treasuries, then rush back in, creating whiplash.
3️⃣ Over-Correction From Last Week’s Rally
The Fed desk forced mortgage rates down to 6.20% by compressing the MBS gap. That move went against market math. Now yields are snapping back as traders try to re-price risk on their own terms.
4️⃣ Global Money Flows Are Shifting Again
Overseas buyers have been inconsistent for months. When foreign demand cools even slightly, the yield moves fast—and today’s jump has that exact signature.
5️⃣ Algorithmic Trading Is Amplifying Every Tick
Once the yield breaks key thresholds, algorithms step in. That’s why we’re seeing sharp moves instead of smooth curves. Small headlines = big swings.
6️⃣ Year-End Rebalancing Has Started Early
Funds are cleaning up portfolios before December. When they dump bonds or rotate into stocks, the yield reacts instantly—especially in a thin post-holiday market.
Today’s Headline: Is an Investment Shift coming
This could be the start of something new. CNN’s Fear & Greed Index is back up this morning, which means they are cautious and selective on where they invest. Looks like they are sticking to stocks and not bonds.
CNN Business ~ Fear & Greed Index 12-5-2025
Who’s Really to Blame for High Mortgage Rates Overall
1 U.S. Treasury Department
- Why they matter: They issue massive amounts of government debt to fund spending.
- Impact: More debt = more Treasury bonds = higher yields = higher mortgage rates. 🚨 Today, the Treasury is auctioning T-bonds, and that’s also creating havoc and chaos in the bond markets.
- When the Treasury floods the market with bonds, investors demand higher returns. Mortgage rates typically follow the 10-year Treasury yield, causing rates to rise as well.
“Mortgage rates may not decline, even with a Fed rate cut, if there is high inflation, and also if somehow the Treasury debt issuance becomes large.” — Lawrence Yun, Chief Economist, NAR
2 Congress & Fiscal Policy
- Why they matter: They approve budgets, stimulus, and deficit spending.
- Impact: Large deficits force the Treasury to borrow more, driving up the yield price.
- Translation: If Congress keeps spending without offsetting revenue, it fuels the debt spiral and pushes mortgage rates higher.
3 Bond Market & Investor Sentiment
- Why they matter: Mortgage rates closely track long-term bond yields, particularly the 10-year Treasury yield.
- Impact: If investors fear inflation, recession, or political instability, they demand higher yields.
- Translation: Mortgage rates spike when bond buyers get nervous or expect more Treasury issuance.
4 Mortgage Lenders & GSEs (Fannie/Freddie)
- Why they matter: They price loans based on risk, demand, and bond spreads.
- Impact: If spreads widen (e.g., between mortgage-backed securities and Treasurys), rates go up.
- Translation: Even if Treasury yields are stable, lenders can raise rates to protect margins or offset risk.
🔮 My crystal ball is cloudy, but here’s what’s clear: This market isn’t reacting like it used to. The last three rate cuts drove mortgage rates up, but this time is different. Jobs, not inflation, are steering policy. I expect less volatility because the Fed is actively compressing the MBS gap to maintain steady rates, even if yields spike. Brace for Whiplash; it has happened before. 📉
📍 If you’re buying or selling in Metro Detroit, understanding why rates move is your edge. Knowing this helps you secure smarter deals and navigate the market with confidence.
💡 Final Thoughts:
Mortgage rates don’t just “happen.” We’re in a market where mortgage rates are no longer tied strictly to the 10-year Treasury yield. The quiet hand of the Fed desk is actively shaping the spread — sometimes tightening it to cool rates, other times widening it to correct overreactions.
For homebuyers and lenders, this means one thing: volatility without warning. Even a stable bond market doesn’t guarantee stable mortgage rates. Keep an eye on the MBS gap and Treasury yield spread this week — they’ll tell you far more than any headline rate chart can. Let’s see how this plays out in Metro Detroit’s housing market as the week unfolds.
Government Reopens, and the Bond Market is throwing a fit! 🤯~ 12-5-2025 Update at 10:30 🕥
The 10-year Treasury Yield: Volatile!
It’s the start of a new month, and following last week’s yield spike, the goal is to see a slow and steady decline. Investors are pricing in long-term risk, and there seems to be a disconnect due to deep distrust in the Fed’s assessment of inflation and its ability to provide economic clarity. 🚨The yield has increased and is climbing. At 11:00, the yield increased to 4.127%. Nope, Wall Street is not taking the bait after a lower PCE inflation report. We could see a yield revision today if the Fed Desk reprices mortgage rates.
Two Mortgage Rate Days?
🤯 Remember: Lenders may adjust mortgage rates up or down if the 10-year yield shifts by ±0.020% until 1:00 PM. I’m watching 👀 to see if this spike holds or if we get a late-day correction lower.
Mortgage-backed Securities (MBS) Prices ~ The Unsung Hero 🦸 or the Villain🦹~ 12-5-2025 @ 11:30 🕦
🚨 The second piece in determining mortgage rates is the all-important Mortgage-Backed Securities. Historically, the 50-year average between the 10-year Treasury yield and MBS rates has hovered around 1.72%. Currently, the average range has plummeted from 2.528% on January 3rd, 2025.
📌 Today’s MBS price Gap: will they be our Hero 🦸 or Villain 🦹Update at 11:30 🕦
📰 Mortgage Daily News reports that MBS prices are moderately weaker and could impact Mortgage Rates higher. MBS prices yesterday were at 99.65 and down to 99.57 today. If we see a hero scenario, that will be because the FHFA Fed Desk was controlling the narrative on mortgage rates.
- 🦸 Hero Mode: When Mortgage-Backed Securities (MBS) prices go up, it means investors are willing to accept lower yields in exchange for the stability of mortgage payments. That puts downward pressure on mortgage rates.✅ Result: Lenders can offer lower interest rates because the value of the mortgage bond (the MBS) is stronger. It’s a win for buyers, refinancers, and anyone seeking to secure a better deal.
- 🦹Villain Mode:
Falling MBS prices mean investors demand higher yields to take on mortgage risk, creating upward pressure on mortgage rates.❌ Result: Lenders increase rates to keep spreads profitable or temporarily pause quoting. Additionally, when the yield skyrockets, 🚀 the Fed Security Desk or Freddie and Fannie 🏦 have been using the gap to correct and stabilize volatility in the Mortgage market. Buyers lose buying power, and the urgency to lock on a dip becomes critical.
🔍Always follow the WHY!🚀
-Important 📢 Know Your Lender’s 🏦 Policy on Rate Revisions ~ Morning vs Afternoon
⚠️ Before locking your rate, always understand how your Lender determines their daily mortgage rate. Remember: yield and MBS prices fluctuate throughout the day, so knowing the Lender’s timeline before locking your rate is crucial to saving. 🔏

🔮 Today’s Mortgage Rate Prediction: 12-5-2025 ~ Update by 11:30🕦
This blog post will update the latest bond yield changes as of Noon. Mortgage Daily News reports the first mortgage rate base between 1:00 and 1:30, and Lender revision updates by 3:30. 💥The examples below show why you need to know how your Lender could handle mortgage rate shifts and what time they determine their rates and revisions. 🔁
🔷 Scenario #1: First yield report @ 10:00🕙 MBS Gap at 11:00🕦
The Yield increased by 0.023% to 4.110% and remains stable. What was interesting was that this proved my hypothesis: Wall Street is not taking the bait with the BLS data. The PCE core inflation, the Federal Reserve’s preferred measurement, was lower than expected, and the bond yield remained steady at over 4.110%. Next, we’ll examine the critical role the Mortgage-Backed Securities Gap plays today. (+ or – .01%) Will it be the Hero 🦸 or the Villain? MBS prices aren’t released until 11:00. 🕚
🦸MBS Hero Scenario:
I must pause here. We’ve seen 3 days of modest overall compression, pushing rates below 6.25%. Today could be a repeat of yesterday, and split the difference between the yield increase and the gap, pushing mortgage rates up slightly to 6.25%. With the PCE lower than expected and the Fed’s report on data from June to August, it appears inflation in September was declining. My crystal ball 🔮 is saying Fed interest rate cut. But I can’t read the FHFA Fed desk mind, yet. Will they start compressing the gap for a repeat number three, moving mortgage rates down to 6.13% before the Fed announcement on interest rates?
📌Neutral Scenario:
If the MBS gap stays the same at 2.153% plus today’s yield at 4.110% that would push mortgage rates up to 6.26%
🦹 MBS Villain Scenario:
I don’t foresee a villain scenario today. The Fed desk has been narrowing the gap and forcing mortgage rates lower twice before an interest rate cut. It’s in their playbook, and we could see number three next week.
🧠 Why You Can’t Predict GLS’s Gap Logic Anymore
1️⃣ The Gap Is No Longer Mathematical—It’s Tactical 
2️⃣ They’re Using the Gap as a Smokescreen 🎭
3️⃣ Wall Street’s emotional sabotage meets forensic clarity🧮
👉 Bottom line: The timing of the UMBS change, combined with political gridlock, has boxed mortgage rates in. Until confidence is restored, the path isn’t down — it’s sideways or higher.

Scroll for Rates for the past week.
📉 Today’s Mortgage Rates: A hot mess ~ Here’s your WHY?
Mortgage rates pushed up because the 10-year Treasury yield jumped early and kept climbing. The day opened near 4.110%, already up 0.023%, and by early afternoon it broke into the 4.140% range 📈. When yields rise this fast, lenders often issue mid-day rate sheet revisions—usually around 2:00 PM—to cover the higher cost of money. Even small spikes force a shift, and today’s move was enough to push mortgage rates higher.
Wall Street Isn’t Taking the Bait
On paper, this should have been a calmer market day. Unemployment is up, Core PCE dropped to 2.8%, and the Federal Reserve is actively filtering pass-through inflation to separate real demand from policy-driven price pressure. Normally, that combination would cool yields. Instead, the bond market kept climbing 🔥. Wall Street is signaling a new shift—less trust in policy direction, more defensive positioning—and today’s yield behavior shows they’re no longer reacting the way traditional models predict.
Bottom line ~ a hot mess:
One headline changed the market’s direction Today. Knowing how these chain reactions work helps you stay a step ahead in real estate decisions.
- August Month-End mortgage rates closed at 6.50%
- September Month-End Mortgage Rates closed at 6.37%
- October Month-End Mortgage Rates Closed at 6.28%
- November Month-End Mortgage Rates Closed at 6.22%
📉 MBS Gap Trends: Why MBS Prices Are Being Engineered by the Fed Desk & GLS
📌 The MBS gap has not been following the math since August. 🧮 The Fed desk is determining the outcome of where they want rates to land. We’ve seen huge compressions at .111%, and mortgage rates plummeted to 6.13%. Two days later, a gap correction occurred, and the gap spiked to .148%, resulting in mortgage rates landing at 6.37%. Remember, the Federal Reserve doesn’t determine mortgage rates; instead, the 10-year Treasury yield (set by the Treasury Department) and the Mortgage-Backed Securities (MBS) gap (set by the Federal Housing Finance Agency) do.
The Fed Desk and GLS
1️⃣ Gap Control 🎚️ — The Fed Desk actively engineers the spread (gap) between Treasury yields and mortgage rates. By widening or compressing it, they offset bond market moves.
2️⃣ Artificial Stability 🏦 — When yields rise, they compress the gap so rates don’t spike too high. When yields fall, they expand the gap to keep rates from dropping too far. This creates an engineered illusion of “stable” mortgage rates.
3️⃣ Policy Pressure 📊 — The GSEs (Fannie & Freddie) coordinate with the Desk, ensuring MBS prices align with policy goals — not just market supply and demand.
📉 To put that in perspective: we’ve gone from a market where spreads were holding closer to historical norms, to one where the gap is being forced tighter and tighter. This isn’t natural market behavior — it’s policy-driven compression at work.
Monthly Gap Stabilization Plan
The Fed desk is trying to narrow the MBS gap back to the 50-year average of 1.72%, or at least to 1.88%, as in February 2020, before the shutdown changed everything. In 3 month-end closing gap has decreased .071% and mortgage rates have followed. 🥳
- August Month-end Gap: 2.272
- September Month-end Gap: 2.245
- October Month-end Gap: 2.201
🧩 Who’s Really Compressing the Gap
🔶 Retail lenders don’t have the balance sheet or hedging power to absorb yield shocks or MBS rallies. They’re rate takers, not rate makers—unless they’re portfolio lending (using their own money), which is rare and usually flagged.
🔷 Banks using the Fed’s underwriting system (think Desktop Underwriter or Loan Prospector) are pricing off agency guidelines. They’re not setting rates—they’re executing.
♦️GLS (Government Liquidity Systems)—whether that’s GSEs like Fannie/Freddie or Fed desk operations—are the only entities with the capital, mandate, and tools to compress the rate/yield gap. They can:

⌛What My Crystal Ball 🔮 Tells Me About the Future Mortgage Market
The Core PCE data just proved my hypothesis. Core PCE came down for September 📉, and that was the moment that confirmed my hypothesis. The Fed isn’t calculating pass-through inflation from tariffs, and they don’t need to. When you strip out the noise, the trend is clear: real inflation is easing, drifting toward the 2.3% range that my own calculations have been tracking for months.
And the Fed just signaled they see it too. They’ve quietly shifted their focus to insurance premiums across every platform — home, auto, health. That only happens when they believe the core battle is nearly over. They’re preparing for another interest rate cut, and a falling Core PCE gives them the cover they need. The Fed’s November report is not painting a pretty picture of the economic future.
Wall Street, though, isn’t taking the bait.
Not today. Not with deficits ballooning, Treasury supply piling up, and politics heating the room. You can feel it in the bond market — yields won’t come down, even when the data says they should. Stocks love the idea of lower rates. Bonds don’t trust the story.
And that’s why mortgage rates are stuck in the middle. With yields holding above 4.13%, the only thing keeping rates from rising is the FHFA stepping in and compressing the gap. They’ve already done it three days in a row, and after today’s PCE print, they may have to keep pressing.
So here’s where the crystal ball lands:
- Inflation is easing
- The Federal Reserve now has mathematical formulas to make better decisions regarding inflation.
- But mortgage rates hold steady only if the Fed desk keeps smoothing out the chaos.
That’s the real story today — short, sharp, and exactly what the data just proved.
