Japan Moves to Ban Crypto Insider Trading, Setting Global Regulatory Precedent

Japan's Financial Services Agency is preparing to extend securities-style insider trading prohibitions to cryptocurrency markets under the Financial Instruments and Exchange Act. The landmark move would grant the Securities and Exchange Surveillance Commission (SESC) authority to investigate and penalize illicit digital asset trades for the first time.

The proposed framework, expected to reach parliament by 2026, marks a significant escalation in Japan's crypto oversight. Regulators would gain powers to impose surcharges or pursue criminal referrals for transactions involving undisclosed material information—bringing digital assets under existing market integrity standards.

Policy analysts suggest Japan's regulatory clarity could trigger competitive convergence among major economies. As one of the first G7 nations to formalize crypto-specific insider trading rules, the MOVE may pressure other jurisdictions to accelerate their own regulatory frameworks for digital assets.
