What reserve rules did Japan propose?

TLDR

Japan proposed mandatory liability reserves for crypto exchanges so customers can be refunded after hacks or operational failures.

1. Reserves would be sized like securities firms, roughly 2b40b ($12.7m$255m) scaled by volume and risk, with insurance possibly counting toward the requirement report.
2. The bill is targeted for submission in 2026 and would add formal bankruptcy asset?return procedures via court?appointed administrators coverage.
3. The plan ends the current cold?wallet exemption and tightens asset segregation and customer refund protections update.

Deep Dive

1. Reserve Sizing

Japans Financial Services Agency (FSA) intends to mirror securities?industry practice, requiring exchanges to hold liability reserves sized to trading activity and risk, with ranges used by brokers as a reference point. The FSA may allow part of the reserve via insurance rather than cash only, reducing balance?sheet strain report.

2. Insolvency and Custody

Beyond hacks, the framework would strengthen protections if an exchange fails. It would formalize segregation of customer assets and enable a court?appointed administrator to return assets, improving payout certainty during bankruptcy or loss of control coverage. The plan also removes the current exemption that relied on cold?wallet storage alone, closing a gap where reserves were not required if coins were mostly kept offline update.

3. Timing and Catalyst

The FSA aims to submit legislation in 2026. The push follows high?profile breaches, including DMM Bitcoins roughly 48.2b loss in 2024, which underscored that cold?wallet rules alone do not guarantee fast customer reimbursement coverage.

Conclusion

Japans proposal would shift crypto exchanges toward traditional financial safeguards: capital or insurance set aside for emergencies, stricter custody rules, and clearer bankruptcy recovery. The trade?off is higher operating costs in exchange for faster, more reliable customer refunds in adverse events.
