Professor Selma Lemes, co-author of the Brazilian Arbitration Act (Law No. 9.307/1996), published her annual survey “Arbitration in Numbers”, with data from the eight main arbitral institutions in Brazil, for the 2023/2024 biennium.
Pursuant to this research, in 2024, the number of new arbitrations grew significantly; 376 proceedings were initiated, an increase of 18% over the previous year, which registered 318 new arbitrations. From an economic standpoint, an expressive 162% increase in total amount in dispute was observed, rising from R$ 29 billion in 2023 to R$ 76 billion in 2024. The average value of proceedings grew by 122%, reaching approximately R$ 202 million per proceeding, in 2024.
Regarding the most frequently discussed subjects in arbitration, the research found the sectors that traditionally lead the number of proceedings – corporate disputes, construction and energy – remained the most prominent.
A relevant increase in the number of new arbitral proceedings involving direct and indirect Public Administration was also identified. In 2024, 32 arbitrations involving the governmental entities were initiated, with total value of R$ 10,2 billion. Currently, there are 131 arbitral proceedings in progress involving the Public Administration, amounting to R$ 101,5 billion. These figures are evidence of the commitment of public authorities to use arbitration as one of the main dispute resolution methods.
The survey also identified a significant increase in the admission of third parties to arbitral proceedings, either as assistants or interested parties. The inclusions occurred mainly in corporate disputes, identified in CAM-B3 – which mostly deals with disputes in publicly traded companies – and in CAM-CCBC, which recorded 77 and 22 cases of third-party intervention, respectively.
The increase in the number and value of expedited arbitration cases – proceedings that are generally of less complex nature and involve lower amounts – was also noteworthy. In 2024, 40 expedited arbitral proceedings were initiated, in six arbitration chambers, amounting to approximately R$ 68 million, an increase of 129% compared to the amount recorded in the previous year. CAM-CCBC remained the chamber with the highest number of expedited arbitration cases, registering 21 new proceedings.
Once again, the survey demonstrates the success and prominence of arbitration in the business word, both nationally and internationally, maintaining Brazil one of the main players in the global market.
