# South Korea faces debt crisis and leveraged trading collapse > Live situation record from CLSTR: https://clstr.news/situations/south-korea-housing-loan-regulatory-tightening > Updated: 2026-08-11T23:22:49.000Z. Sources: 32. Developments: 24. By mid-2026, South Korean financial stability faced mounting pressure from soaring household leverage and retail speculation. In July, Financial Supervisory Service chief Lee Chan-jin warned of surging stock-borrowed investing, with credit-loan balances reaching 37.3 trillion won in June. This coincided with a wave of margin calls affecting over 1.2 million leveraged retail accounts, leading to hundreds of thousands of liquidations. To curb debt, major lenders like KB Kookmin Bank implemented aggressive tightening, including halving mortgage limits from 600 million to 300 million won. These restrictions sparked political criticism and fears of a “balloon effect,” where tightened bank credit pushes borrowers toward higher-cost alternatives like P2P loans and savings banks. By late June, the five largest banks had already exceeded their annual household-loan growth targets, prompting the Bank of Korea to raise the policy rate to 2.75% in July. The systemic risk materialized in August when a collapse in leveraged ETFs tied to semiconductor giants erased billions, contributing to a massive KOSPI decline. This “leveraged trading blow-out” resulted in retail investors losing approximately 56.3 trillion won. Concurrently, banks are navigating a dual crisis: rising bad debt and intense deposit competition. Non-performing loans (NPLs) exceeded 6 trillion won, with corporate NPLs rising over 36% due to high interest rates and a real estate downturn. To counter potential capital outflows from the stock market, banks have launched aggressive high-interest deposit products to attract liquidity. ## Claims - Between 300 000 and 700 000 young South Koreans suffered significant losses from leveraged trading.
