韩国 South Korea tightens single-stock leveraged ETF regulations, margin threshold raised to 30 million KRW The South Korean Financial Services Commission announced that starting July 31, the margin requirement for single-stock leveraged ETFs/ETNs will be increased: Individual investors must hold at least 30 million KRW in cash for new purchases or additional buy-ins. Only cash is accepted—stocks, bonds, and other assets will no longer be considered. The new rule comes as the scale of single-stock leveraged products has skyrocketed—total market value of 16 products surged from 4.4 trillion KRW on May 27 to 11.9 trillion KRW on July 15. Selling operations are not subject to this restriction.
