Japan upgrades crypto to regulated financial instruments, adds investor safeguards and insider trade ban

The Japanese government approved an amendment to the Financial Instruments and Exchange Act (FIEA) on April 10 that will classify crypto assets as financial instruments rather than treating them solely under the Payment Services Act, according to reporting based on government sources and Nikkei coverage ^{[1] [2]}.

The legislation introduces new oversight measures, including a ban on insider trading related to crypto and strengthened investor protections, bringing crypto trading within FIEA rules for the first time, the reports say ^{[1] [3] [4]}.

Some outlets report the reforms will be implemented in stages with a target rollout around 2027, and regulators are expected to publish detailed rules and consultations as they move to operationalize the change ^{[4] [3]}.

Lawmakers have approved the bill, and market participants should expect follow-up rulemaking and implementation guidance from regulators to clarify compliance requirements under the new FIEA framework ^{[1] [4]}.
