## Critical Fed Test
The S&P 500 faces its most consequential Federal Open Market Committee meeting this year as inflation proves stubborn and a rate hike is widely expected.
## Iran Deal Impact
The summer US-Iran peace deal reopened the Strait of Hormuz but inflation metrics remain sticky, delaying Fed action.
## Warsh's Moves
Fed Chair Kevin Warsh may hike rates to 3.75% and disrupt central bank messaging with alternative metrics and forward guidance changes.
## Tech Sector Risk
Aggressive AI spending in big tech has reduced free cash flow buffers, making companies vulnerable to rate hikes.
## Software Valuation
Spiking Treasury yields are compressing software valuations as high multiples face severe resets from rising discount rates.
## Near-Term Scenario
A hawkish Fed move could trigger immediate S&P 500 selloffs, especially in long-duration growth stocks.
## Key takeaway

S&P 500 faces immediate pressure from rate hikes and communication shifts as Fed moves faster on inflation.
