A recent research paper from the Bank for International Settlements (BIS) outlines a proposal that would grade cryptocurrencies based on their transaction history and assign compliance scores. This framework aims to flag assets linked to suspected illicit funds like those used in money laundering, lowering their scores and potentially restricting conversions into fiat currency. National regulators could set minimum score thresholds for these conversions, barring exchanges from processing if an asset falls below that mark. BIS believes this approach can deter the flow of illicit funds while increasing trust among institutions. However, BIS remains cautious about cryptocurrencies, highlighting their volatility as a potential threat to financial stability and emphasizing the need for robust oversight in the industry.
