Find out more about PISCES[2]

We are running a sandbox until June 2030 to test the regulatory framework for PISCES.

This will allow entities hosting a PISCES platform (operators) to test out various business models.

The benefits include testing:

Live in the market with real companies and investors.
Within a proportionate and flexible regulatory framework.

The FCA and the Treasury will monitor the outcomes and decide whether to transfer PISCES into permanent legislation or other next steps.

We consulted on PISCES framework.

Pre-application support opened.

Final rules published.
Sandbox opened.
