The Chicago Board of Trade has signed a surveillance agreement with the Tokyo Stock Exchange to monitor trading activity in futures on the Tokyo price index.

The Tokyo Stock Exchange plans to begin trading Tokyo price index stock futures later this summer, and the Chicago Board of Trade said it will start trading the futures in Chicago as soon as possible after the Tokyo launch, possibly by the end of the year. The agreement allows both exchanges to share information regarding trading in the futures.

“We have reached this agreement in order to provide complete protections for all parties involved in the trading of these upcoming futures contracts,” CBT Chairman Karsten Mahlmann said in a release.

“This understanding symbolizes the close working relationship between the world’s largest futures exchange and the world’s largest securities exchange,” Mahlmann said.

The Tokyo exchange also has signed a formal surveillance agreement with the Chicago Mercantile Exchange, which plans trading of stock index futures based on the Nikkei 225-stock index.
