South Korea Eases Margin Loan Rules After KOSPI Crash

South Korea is temporarily suspending collateral requirements for margin loans to prevent forced stock liquidations following a sharp KOSPI market selloff.

The government of South Korea is temporarily easing collateral requirements on margin loans for three months to prevent a wave of forced stock sales. Finance Minister Lee Hyoung-il chaired an emergency financial market review meeting where officials decided to suspend the mandatory 140% collateral maintenance ratio for securities firms. This measure grants brokerages more flexibility to manage investor collateral and avoid immediate margin calls.

The intervention follows a severe market rout on Friday, during which the benchmark KOSPI plunged as much as 8.8%. The index fell below the 5,000-point threshold for the first time in nine months, triggering a 20-minute trading halt.

Semiconductor giants Samsung Electronics and SK Hynix led the selloff. The crash was influenced by overnight losses on Wall Street, driven by investor concerns regarding data-center regulatory constraints and the returns on artificial intelligence investments. The emergency meeting included representatives from the Financial Services Commission, the Financial Supervisory Service, and the Industrial Bank of Korea.
