The Bank for International Settlements Innovation Hub released a retrospective report reviewing the six editions of the G20 TechSprint held from 2020 to 2025, focusing on how the initiative has evolved and its role in fostering innovation and central bank collaboration. The 25-page report is supported by a survey of G20 TechSprint winners, capturing participants’ experiences, insights and observations, and using this feedback to assess the programme’s development and perceived impact.
