Why it may matterVerify against the original reporting
A rate hike elevates discount rates, typically compressing P/E multiples and increasing corporate financing costs, which can pressure broad equity markets in the short term. History shows initial volatility after policy-tightening steps, with sector rotations and multiple compression acting as key drivers until the rate path and inflation trajectory become clearer.
