Japan is preparing a major regulatory overhaul to curb crypto insider trading, a move that could significantly influence international standards for digital asset market integrity.
The plan, spearheaded by the Financial Services Agency (FSA), will empower its market watchdog, the Securities and Exchange Surveillance Commission (SESC), to police illicit crypto trades. Once formalized, likely by 2026 under an extension of the Financial Instruments and Exchange Act (FIEA), the SESC will have the authority to investigate suspicious trades and recommend criminal referrals or surcharges for transactions based on undisclosed information.
This legislative-first approach is being welcomed by policy experts for providing clarity over “case-by-case improvisation,” which has characterized the U.S. approach. Experts suggest that by applying securities-style rules to digital assets, Japan is aligning its regulatory philosophy with the EU’s MiCA framework, creating a “de facto clarity bloc” that institutional investors will find legible.
This decisive action puts pressure on jurisdictions like the U.S. to develop a clearer federal framework. As one policy head noted, “Integrity is now a baseline requirement,” and Japan’s move makes it “politically straightforward” for other countries to treat insider trading in tokens as a crime, not a grey area.
