South Korea's stock market is crashing hard, wiping out huge numbers of small investors — bad news for Korean households now, and a warning sign for US markets later.

• A record sell-off has crushed over 700,000 small Korean traders, many wiped out on leveraged bets tied to Samsung and SK Hynix.
• The crash kept falling even after Samsung confirmed big profits — people are running for the exits regardless.
• The government is weighing five rescue moves: a national bailout fund, a short-selling ban, limits on leveraged ETFs, tighter margin rules, and looser buyback caps.
• Officials pushed households into the AI and chip stock mania, so now there's heavy political pressure to step in.
• The worry is these losses spread outward — into Europe, then the US, where many investors are also piled into leveraged S&P and Nasdaq funds.

Outlook: Korea will likely be forced to deploy one or more rescue levers soon, and the same playbook is what the US may reach for if its own market turns down.
