South Korea's Fair Trade Commission imposed fines totaling approximately ₩1.6 trillion on 15 banks and securities firms for collusion in government-bond auctions. The regulator said dealers exchanged bidding-yield information through telephone calls and Telegram between January 2020 and June 2023, covering 150 auctions. In 145 auctions, the firms allegedly coordinated both yields and bidding volumes, according to the authority's findings. The regulator concluded that the practices artificially increased government borrowing yields; the findings and penalties may still face legal challenges.

This is a major enforcement action involving market integrity, institutional compliance, and public borrowing costs.
It may influence how primary dealers manage communications, bidding processes, surveillance, and regulatory exposure.
