JPX Market Innovation & Research, Inc. (JPXI) and QUICK Corp. today announced that they will jointly calculate and operate a series of indices that reflect the price movements of yen-denominated spot crypto asset transactions conducted in Japan.

JPXI and QUICK have leveraged the expertise of both companies to examine index design and operational frameworks that align with conditions in the domestic crypto asset market.

From today, the index currently calculated and published by QUICK as the “QUICK Bitcoin Index” will be renamed the “JPX–QUICK Bitcoin Index.” Related index documents and operational materials will also be published. In addition, the two companies will calculate and publish the “JPX-QUICK Ethereum Index.”

Based on discussions held by the “Crypto Asset Benchmark Study Group,” QUICK began trial calculation of the “QUICK Bitcoin Index” in April 2025. Full-scale calculation commenced in December 2025, and the index has since been published on a daily basis.

To ensure fairness and transparency in index operations, JPXI has established operational policies governing the calculation of the JPX–QUICK Crypto Asset Index Series.

Index values for the JPX–QUICK Bitcoin Index and JPX-QUICK Ethereum Index will be published on the QUICK website and through QUICK terminal services.
