# Why S&P 500 (SP500) fell 4.24% on November 6, 2026

S&P 500 (SP500) fell 4.24% on November 6, 2026 — Fed overhaul plan rattles rate-outlook bets.

## What happened

The S&P 500 fell 4.2% as reports that Fed Chair Kevin Warsh is planning to break 45 years of monetary-policy precedent weighed on markets during a broader tech rout. The plan is still a proposal, not an enacted change.

## Why it moved

A rewrite of Fed precedent would change how investors price the discount rate, and uncertainty about the policy path lifts the term premium. That pressures risk assets across the index.

## Why it matters

Under US Index & Macro, the question is whether policy-regime uncertainty becomes a durable valuation discount rather than a one-day headline. Index-level moves like this reflect that repricing.

## What would break the thesis

If the plan is shelved or lacks support from the Fed or White House, the policy-risk premium should unwind quickly. Any formal Fed communication on the framework would be the clearest signal.
