A MiCA CASP License Can Travel Across the EU, but It Does Not Turn Into a Universal Financial Passport
A MarsBit analysis argues that the biggest misunderstanding around the EU’s Markets in Crypto-Assets framework is not whether a crypto-asset service provider, or CASP, can expand across borders after authorization. It can. The real issue is what exactly gets carried into other member states through passporting, and what does not. Under MiCA, a CASP authorized in its home state may extend approved crypto-asset services into other EU countries through a branch or on a freedom-of-services basis, without setting up a separate licensed entity in each market. But the scope remains limited to the services already listed in the authorization. A cross-border notification does not automatically add fiat conversion, trading venue operations, order execution, or investment advice. The article also says many business models, especially crypto payments, sit partly outside CASP authorization. Stablecoin flows may overlap with payment regulation, and the European Banking Authority has discussed how MiCA interacts with PSD2, particularly for EMT-related transfers and some custodial wallet functions after transitional arrangements end on March 2, 2026. It also highlights ESMA’s 2025 warning about the “halo effect,” where users may wrongly assume that all products in a group app are MiCA-regulated just because one EU entity holds a CASP license. The broader point is that passporting removes duplicate licensing, not every local, product, and group-structure compliance issue.
