The decision comes amid increased pressure from European regulators on financial institutions to tighten oversight of crypto-related activities.
BiG pointed to compliance with recommendations from the European Central Bank, the European Banking Authority, and the Bank of Portugal.
The banking giant emphasized that its decision to stop fiat transfers also aligns with its efforts to adhere to national regulations aimed at combating money laundering and terror financing.
Delphi Labs co-founder José Maria Macedo criticized BiG, warning that it could encourage more people to adopt DeFi (decentralized finance).
“Crypto is inevitable, banks are dead, and these abuses of power will only red pill more people into moving their wealth on-chain.”
Despite BiG’s restrictions, other Portuguese banks, like Caixa Geral de Depósitos, continue to allow fiat transfers to crypto platforms, indicating that BiG’s stance is not yet a widespread practice.
Portugal was once a crypto tax haven.
However, in 2023, it introduced a 28% capital gains tax on short-term crypto holdings, reflecting a shift towards tighter regulation.
It’s clear that BiG is trying to align with broader European trends, as Markets in Crypto-Assets Regulation (MiCA) seeks to establish a unified framework for digital assets across the EU.
It’s unclear if other Portuguese banks will follow suit, but so far, they have not.
