The State Interests and Governance Authority (SIGA) is the central oversight body established by the Government of Ghana in 2019 to streamline the governance and performance of Specified Entities (SEs), including State-Owned Enterprises (SOEs), Joint Venture Companies (JVCs), and Other State Entities (OSEs).

SIGA was created to address long-standing challenges associated with fragmented oversight by providing a unified, accountable, and transparent framework. This framework ensures fiscal discipline, policy harmonization, effective monitoring and evaluation, and improved information management across SEs. In line with global best practices, SIGA also ensures a clear separation between the shareholder (the State) and policy/regulatory bodies, thereby promoting fair competition and eliminating undue advantages for SOEs.
