Korea's Financial Supervisory Service (FSS) chief Lee Chan-jin apologized for
failing to act to block listings of single-stock leveraged ETFs, saying their
launch had "to some extent" increased market volatility. At a National Assembly
oversight hearing on the 19th, a People Power Party lawmaker cited post-listing
headlines calling the week "Black Monday" through "Black Friday"; Lee reiterated
the ETFs had an effect "to some extent" and added that Samsung Electronics and
SK Hynix had shown pronounced volatility.
