Japan Expands Insider Trading Rules to Cryptocurrencies

Japan's Securities and Exchange Surveillance Commission (SESC) will now enforce insider trading regulations on cryptocurrencies, marking a significant shift in the country's financial oversight. The Financial Services Agency (FSA) is finalizing the framework, with amendments to the Financial Instruments and Exchange Act (FIEA) expected next year.

The move aligns crypto markets with traditional securities laws, banning trades based on undisclosed information. However, defining "insider information" for decentralized tokens remains a challenge. Japan joins the EU and South Korea in tightening crypto regulation, contrasting with more permissive jurisdictions.

This regulatory clarity could boost institutional participation in Japan's crypto markets, particularly for major assets like BTC and ETH. The SESC's new authority to investigate violations and impose penalties replaces previous self-regulatory approaches, potentially setting a precedent for other Asian markets.
