Bison Bank has become the first institution in Portugal to land a full license under the European Union's Markets in Crypto-Assets (MiCA) regulation. The approval, announced this week, gives the bank a regulatory green light to custody, trade, and offer crypto services to clients across the bloc.
What the license covers
MiCA is the EU's sweeping rulebook for crypto assets, designed to replace a patchwork of national laws with a single passport. Bison Bank's license allows it to operate as a crypto-asset service provider from its base in Portugal, covering custody, exchange, and order execution. The bank can now serve institutional and retail clients under the same set of rules in all 27 member states.
Portugal's central bank, Banco de Portugal, handled the application. The regulator has been cautious on crypto in the past, but the MiCA framework gives it a clear standard to assess firms.
MiCA came into full effect in 2025, but national authorities have been slow to issue the first batch of licenses. Bison Bank's approval signals that the system is finally moving from paper to practice. The license is expected to pave the way for broader EU crypto integration, giving other applicants a template to follow.
For institutional investors, the regulatory certainty is a big draw. A full MiCA license means a bank's crypto operations are subject to the same capital, custody, and disclosure rules as traditional finance. That's a step up from the lighter-touch regimes some countries used before MiCA.
Bison Bank's play
Bison Bank is a Lisbon-based institution that has been building out its digital asset arm for a few years. It already offered crypto custody and trading to select clients under Portugal's pre-MiCA rules. The new license lets it scale those services across Europe without needing separate approvals in each country.
The bank hasn't said which specific products it will launch first, but the license covers both crypto-to-fiat and crypto-to-crypto transactions. It also allows the bank to act as a custodian for tokenized securities, a market that's growing as traditional finance experiments with blockchain settlement.
What comes next
Portugal now has a reference point for other applicants. Several crypto firms have set up shop in the country over the past two years, drawn by its relatively friendly tax treatment of crypto gains. Those firms will be watching how Bison Bank's compliance framework works in practice.
The next big test for MiCA is whether the European Securities and Markets Authority (ESMA) will issue additional guidance on stablecoins and decentralized finance. That's expected later this year. For now, Bison Bank has the first-mover advantage in Portugal — and a license that works from Lisbon to Helsinki.
