What if the SEC reclassifies ether as a security?
An SEC reversal reclassifying ETH as a security forcing US staking delistings is an ETH-specific regulatory shock — ETH -7% as the US institutional bid and staking-ETF complex are gutted, MSTR/Coinbase follow on crypto-regulatory beta. The current roots wrongly inject trade_tension, dragging in semis/Alibaba/Nasdaq tariff effects that have no causal link to a securities-law decision. Closer analogue is the 2023 SEC-vs-exchanges enforcement scare; transmission is regulatory, so the cascade should stay inside crypto.

What it would mean
