Why This Comparison Matters
Freddie Mac MORTGAGE30US printed 6.30 percent on April 30, 2026, off the October 26, 2023 peak of 7.79 percent, with the S&P 500 at a record 7,165.08 on April 24. Mortgage rates still 308 basis points above the 3.22 percent January 2022 starting line alongside equities at all-time highs: a housing-finance regime not normalized, an equity tape rerated on AI capex.
Why the mortgage-equity disconnect of 2022 to 2026 is the key episode
From January 2022 to October 2023 the 30-year fixed rate climbed from 3.22 percent to 7.79 percent, the largest 21-month move in the Freddie Mac series since 1981, and SPY drew down 25 percent peak-to-trough by October 2022. That window obeyed the textbook script in which housing finance and equity multiples both responded to the discount-rate channel. The script broke in late 2022. Mortgage rates stayed in a 6 to 7.79 percent band through 2024 and into 2026 while SPY first recovered the 2022 drawdown by July 2024 and then added another 35 percent into the April 2026 record at 7,165.
The break has a specific mechanical cause. Mortgage rates price off the 10-year Treasury plus the primary-secondary spread, which has run 250 to 290 basis points wider than the 1990 to 2019 average of 170 basis points because of MBS convexity hedging and the post-March 2023 regional-bank retreat from MBS purchases. Equity multiples by contrast have rerated on AI capex commitments that are largely insensitive to the mortgage market. The Microsoft April 29 fiscal Q3 capex guide of $190 billion for FY2026 is the textbook example: a capex line that is 61 percent higher year over year, that flows directly to mega-cap earnings power, and that has nothing to do with the 30-year fixed rate. The cross-asset desk reads the spread as a measure of how decoupled the two transmission channels have become.
The 1981 reference point and what 7.79 percent really meant
The October 26, 2023 print of 7.79 percent was the highest weekly reading since November 30, 2000, but it remains roughly half the all-time peak. Freddie Mac's series printed 18.63 percent on October 9, 1981, during the Volcker disinflation. The 2023 episode was the first time since the early 1980s that mortgage rates more than doubled inside two calendar years. The Federal Reserve raised the funds rate from a 0 to 0.25 percent target band in March 2022 to 5.25 to 5.50 percent by July 2023, a 525 basis-point move in 16 months that the Atlanta Fed

Frequently Asked Questions
Why did SPY rally to record highs while mortgage rates stayed above 6 percent?+
The lock-in effect insulated US household cash flow from the headline rate move. Roughly 60 percent of outstanding US mortgages carry rates below 4 percent, and existing-home sales fell from 5.97 million annualized in October 2022 to 3.84 million in October 2023 because most homeowners chose not to refinance into the new rate regime. With household debt service ratios stable, the wealth effect from rising home equity continued to support consumer spending. SPY's rerate from October 2022 lows was driven primarily by AI capex commitments (Microsoft FY2026 capex guide of $190 billion is the most-cited example) rather than by housing-channel transmission, so the historical relationship between mortgage rates and equity multiples broke for the duration of this cycle.
What was the highest 30-year mortgage rate in history?+
Freddie Mac's PMMS series printed 18.63 percent on October 9, 1981, during the Volcker disinflation when the Fed funds rate ran above 19 percent. The October 26, 2023 print of 7.79 percent was the highest weekly reading since November 30, 2000, but remains roughly 11 percentage points below the all-time peak. The 2022 to 2023 episode was distinctive less for absolute level than for rate of change: the largest 21-month move in the Freddie Mac series since 1981, with the 30-year fixed climbing from 3.22 percent in January 2022 to 7.79 percent in October 2023 alongside the Fed's 525 basis-point hiking cycle.
How does the primary-secondary spread affect mortgage rates?+
The primary-secondary spread is the gap between the Freddie Mac 30-year rate and the secondary-market MBS yield that funds it. It ran 290 basis points in October 2023 against the 1990-2019 average of 170. The widening reflects the Fed's exit as a marginal MBS buyer when QT started in June 2022, the post-March 2023 regional-bank retreat from MBS portfolios after Silicon Valley Bank's failure, and the convexity-hedging premium dealers charge during high rate-volatility periods (the MOVE index ran above 100 for most of 2022 to 2023). The structurally wider spread is why the 30-year fixed has stayed sticky even as the 10-year Treasury yield has fallen 80 basis points from its October 2023 peak.
