TLDR:
- Japanese FSA introduces new reserve fund requirements for crypto exchanges.
- Crypto exchanges must maintain reserve funds to protect against losses.
- Japan to strengthen crypto security with new compensation reserves.
- New FSA rules aim to boost crypto investor confidence amid hacks.
- Japan redefines crypto regulations, with insurance and reserve mandates.
The Japanese Financial Services Agency (FSA) plans to introduce a new set of regulations for cryptocurrency exchanges. These rules will require exchanges to maintain reserve funds to protect customers from losses due to hacking or operational failures. The move aims to provide an extra layer of security for cryptocurrency traders amid a series of high-profile security breaches in the industry. With this new mandate, the FSA hopes to strengthen consumer protection and increase confidence in the growing digital asset market.
New requirements for crypto exchanges
Under the proposed regulation, Japanese cryptocurrency exchanges will be required to set aside reserve funds specifically for customer compensation. This will cover potential losses due to unauthorized access or other operational failures. The amount of reserve required will depend on factors such as the exchange’s trading volumes and its security track record. For comparison, traditional securities firms in Japan must hold between 2 billion and 40 billion yen in reserves.
Exchanges may be permitted to use insurance policies to partially meet reserve requirements. These funds will ensure that in the event of a loss, compensation to customers can be made quickly without compromising the financial health of the exchange. The FSA’s new rules bring Japan’s crypto regulations in line with those of traditional finance, providing more predictable guarantees for investors.
Closing safety and regulatory gaps
Japanese crypto exchanges are only required to store customer assets in cold wallets to protect them from online threats. However, recent security breaches, such as the 2024 Bitcoin DMM hack, have demonstrated the limits of these measures. In this case, attackers exploited vulnerabilities, resulting in a loss of more than 48 billion yen ($308.5 million). The FSA’s new rules aim to address these loopholes by introducing a reserve fund system that will protect traders against similar incidents.
In addition to reserve requirements, the FSA’s regulatory overhaul includes stricter asset segregation rules. This will ensure that client assets are segregated from exchange holdings, further protecting investors’ funds. If an exchange goes bankrupt, the new framework will allow for the return of customer funds through a court-appointed administrator, streamlining the process.
Broader regulatory reforms to come
The proposed changes are part of a broader shift in Japan’s regulatory approach to digital assets. By 2026, the FSA plans to submit a bill that would reclassify cryptocurrencies as financial instruments under the Financial Instruments and Exchange Act. This would bring them closer to traditional securities, subjecting exchanges to insider trading bans, stricter audits and enhanced disclosure requirements.
The reclassification is expected to support the growth of regulated crypto investment products such as ETFs and investment trusts. It will also introduce tax reforms, with a flat 20% tax on crypto gains, replacing the current variable rates which can exceed 50%. The move aims to balance consumer protection with promoting digital asset innovation in Japan.

Japan’s push for tighter regulation in the crypto market reflects a global trend toward tighter oversight in the digital assets space. As the country continues to refine its crypto regulations, the FSA is focused on protecting traders while fostering an environment conducive to secure investment growth.
