Japan’s Financial Services Agency (FSA) have made significant developments regarding insider trading regulations in Japan over the years, and current reports suggest the FSA is planning future changes, particularly related to cryptocurrencies. Historically, insider trading regulations were introduced in Japan in 1988 under the Securities and Exchange Law (SEL), which was later incorporated into the Financial Instruments and Exchange Act (FIEA).
The FIEA, specifically Article 166, prohibits trading based on material non-public information, aiming to ensure fairness and transparency in the securities market. These rules were strengthened over time, with notable amendments in 2004 introducing an administrative surcharge regime and further refinements to enforcement practices.
As of recent developments reported in March, the FSA is planning to amend the FIEA to classify cryptocurrencies as financial products. This proposed change, expected to be submitted to Japan’s parliament as early as 2026, would extend existing insider trading restrictions to crypto assets. Currently, cryptocurrencies are regulated under the Payment Services Act as a “means of settlement,” not as financial products akin to stocks or bonds. The forthcoming amendment aims to address gaps in oversight, particularly to curb insider trading in the rapidly growing crypto market, aligning digital assets with traditional financial instruments under stricter regulatory scrutiny.

While these plans indicate a future expansion of insider trading laws to include cryptocurrencies, no new laws have been formally introduced or enacted as of now. The FSA’s initiative reflects an ongoing effort to adapt regulations to emerging financial technologies, building on decades of evolving insider trading policies in Japan. The implications of Japan’s Financial Services Agency (FSA) planning to amend the Financial Instruments and Exchange Act (FIEA) to classify cryptocurrencies as financial products and extend insider trading laws to them are wide-ranging, affecting markets, investors, businesses, and regulatory frameworks.
Extending insider trading laws to cryptocurrencies would level the playing field by applying the same fairness standards to crypto markets as traditional securities. This could reduce manipulation, such as “pump and dump” schemes or trades based on non-public information (e.g., exchange listings or partnerships), which have been prevalent in the less-regulated crypto space. Clearer regulations might boost trust among retail and institutional investors, encouraging broader participation in Japan’s crypto market, one of the world’s most active.
Crypto exchanges, wallet providers, and token issuers would need to align with FIEA requirements, similar to those for stocks and bonds. This includes implementing systems to detect and prevent insider trading, potentially increasing operational costs. Japan’s move could set a precedent for other nations, pressuring international crypto firms to adapt if they want to operate in or with Japan, a significant market known for its progressive stance on digital assets. Stricter rules might stifle innovation by imposing heavy compliance demands on startups or smaller projects, particularly those issuing new tokens (ICOs or otherwise).
Developers might face hurdles in navigating what constitutes “material non-public information” in a decentralized ecosystem. Larger, well-funded firms with resources to comply could dominate, while smaller players might exit or avoid Japan, reducing market diversity. Unlike traditional markets with clear corporate insiders (e.g., executives), crypto’s decentralized nature complicates identifying who qualifies as an “insider.” For instance, would developers, miners, or large holders.
