South Korea’s Ministry of Economy and Finance is convening a high-level market meeting on Thursday, pulling together the country’s most powerful financial regulators in what appears to be a coordinated response to escalating market turbulence.

The so-called F4 meeting brings the Ministry together with the Financial Services Commission, the Financial Supervisory Service, and the Bank of Korea.

What’s driving the meeting

The primary catalyst appears to be rising volatility tied to single-stock leveraged ETFs. Adding to regulator anxiety, major corporations in South Korea’s chip and shipbuilding sectors have been actively divesting positions in the forwards market.

The specific agenda and expected outcomes of Thursday’s meeting haven’t been publicly disclosed.
