## Fed raises rates again
On September 16, 2026, the Federal Reserve hiked its baseline interest rate by a quarter percentage point to a new range of 3.75% to 4%.
## Inflation still elevated
The Fed cited elevated inflation as the reason for the hike. Consumer prices rose 3.4% over the past year, well above the 2% target.
## A two-speed economy
The U.S. economy is moving at very different speeds. AI investment is booming while housing and traditional businesses struggle with high costs.
## Housing market crushed
High mortgage rates and diminishing affordability are crushing the housing market. Rates are nearing 7%, pricing out many potential buyers.
## The lock-in effect
Millions of homeowners financed at 3% or 4% rates, so they're staying put. There's little incentive to sell and buy another home at much higher rates.

> Persistently high mortgage rates are reinforcing the "lock-in" effect for current homeowners.
## Treasury yields spike
The yield on the 10-year Treasury crossed 5% on September 14 for the first time since 2023, driven by inflation concerns and soaring government debt.
## Oil adds inflation pressure
The war with Iran has pushed oil prices back above $100 a barrel, adding new inflation pressure through gasoline, diesel, and transportation costs.
## AI investment keeps booming
More than half of recent capital-spending growth is attributed to AI buildout. Companies expect huge returns, so higher rates barely slow their investment.
## Consumers stretched thin
Consumers are carrying ever more expensive credit card and auto debt. Many are increasingly dipping into their savings despite higher returns on safe assets.
## Federal debt tops $40 trillion
As the Treasury issues new debt at higher rates, federal interest costs will gradually rise. The national debt recently topped $40 trillion.
## Key takeaway

The Fed's rate hike will hit struggling sectors like housing hardest while barely slowing booming AI investment.
