[Alpha Biz= Reporter Kim Jisun] The suspension of U.S. stock daytime trading through domestic securities firms led to the cancellation of approximately 630 billion KRW in transactions across about 90,000 investor accounts.

According to Yonhap News on the 7th, the Financial Supervisory Service reported that this amount was refunded to investor accounts following the cancellation of trades by Blue Ocean, an Alternative Trading System (ATS) for U.S. daytime trading.

Nineteen domestic securities firms had been providing daytime trading brokerage services for U.S. stocks during off-hours (9 a.m. to 5 p.m. KST) in partnership with Blue Ocean. However, on the 5th, Blue Ocean unilaterally canceled all trades placed after 2:45 p.m. KST due to a surge in orders caused by heightened volatility in the global stock market.

As a result, all orders were canceled, nullifying both the losses and gains from the daytime trading of stocks. Blue Ocean resumed trading on the 7th, but only for 29 exchange-traded fund (ETF) stocks after being closed on the 6th.
