Warsh Jackson Hole hawkish tilt lifts Sept rate hike bets, impacting S&P 500

Why it may matterVerify against the original reporting

A credible path to a September hike raises discount rates and compresses equity valuations; higher yields historically pressure P/E multiples and can trigger sector rotation away from equities. For example, rate-hike cycles in 2018 and 2022 pressured multiple-driven gains even when data remained mixed.
