MIDWEEK RECAP ⏪
-------------------
The December Non-Farm Payroll report (November data) was originally due last week but was rescheduled to yesterday (Tuesday).
Inflation, employment, and The Fed make up my “Big 3” market movers.
Inflation (CPI/PCE)
The Fed (FOMC/Minutes)
Employment (NFP/ADP)
Despite the hope that a softening labor market would push mortgage rates back to the October lows, the NFP data was a mixed bag that only nudged bond prices slightly higher.

Today was even more uneventful, with a mostly flat session for all sectors, although crypto continues to lose ground while precious metals have taken over as the preferred hedge.
IMPACT CALENDAR 📅
-----------------------
This is a double whammy week with another Big 3 data set on deck tomorrow, the Consumer Price Index (CPI) inflation report.
This is the last major report before investors likely completely check out for the year.
However, if this week does prove uneventful, and we continue to trend sideways into the new year, there should still be a collective sigh of relief.
Finishing off the month unscathed will put 2025 as the best year for mortgage rates since 2020.

RATE PRICE INDEX 📉
----------------------
Mortgage rates DO NOT rise or fall.
The full range of rates is always available, and instead the price of each rate changes based on the trading of individual mortgage bonds.
The LendZen Index calculates a daily change in the price of mortgage rates by tracking a spectrum of mortgage-backed securities (MBS).
-----------
24-Hour: +1 bps (+$13 per $100K)
5-Day: +4 bps ($40)
10-Day: +1 bps ($8)
30-Day: -21 bps (-$207)
60-Day: -25 bps (-$248)

Since peaking on January 16, mortgage rate PRICES have declined by over 300 basis points.
That means the cost of getting a $500k mortgage (regardless of rate) is $15,000 cheaper today than at the start of the year.

RATE LOCK GUIDE 🔒
---------------------
The LendZen LOCK-O-METER provides borrowers with a risk-weighted score based on how various macroeconomic events, including market data, central bank announcements, and geopolitics, each historically impacts the price of bonds.
higher risk scores = lean towards locking
------------------
Closing Window
------------------
[ 15 Days ] — 86 🔴
NFP failed to meaningfully help bonds and CPI risk is now concentrated into a single release. Short-term lock risk inches higher as the window narrows.
[ 30 Days ] — 69 🟠
With CPI tomorrow’s wild card, there’s little buffer left before year-end. Any upside inflation surprise would be difficult to recover from in this timeframe.
[ 45 Days ] — 59 🟡
The medium-to-longer-term window is steady, but direction hinges on whether CPI confirms or disrupts the disinflation narrative.
[ 60 Days ] — 46 🟡
Longer-term optimism remains intact after NFP came and went without impact. Assuming CPI doesn’t derail bonds either, early-2026 pricing will still benefit from 2025’s strong rate improvement.
