Abstract

The objective of this article is to study the development of the international dimension of the Basque Economic Agreement from a long-term perspective (1878-2025) and, in particular, to analyze the evolution of the framework for the participation of Basque institutions in international fiscal organizations and forums. The article provides a detailed analysis of the agreements reached between the Basque institutions and the Spanish State in 2024 and 2025, with the aim of updating and strengthening the foral participation model and increasing the visibility and international presence of the Basque Treasuries.
