This week, the Basel Committee on Banking Supervision released the Basel III monitoring statistics for December 2023, including exposure to crypto assets. Given that this data is somewhat outdated due to the upcoming launch of the Bitcoin ETF in the United States, it has already shown a significant increase in U.S. banks offering crypto services to clients. In particular, the Americas have almost completely withdrawn from the cryptocurrency custody space, mainly due to the U.S. SEC's SAB 121 accounting rules prohibiting banks from providing custody services, while the incoming Trump administration is likely to completely abandon this rule. In the second half of 2023, custodial assets in Europe grew by 49% compared to the first half, reaching 5.5 billion euros (5.8 billion dollars). Globally, 94% of custody is in spot cryptocurrencies rather than tokenized assets or ETPs. In terms of client exposure, the Americas dominate, providing 98% of the services. U.S. banks generated a risk exposure of 190 billion euros (201 billion dollars) for their clients. U.S. banks also significantly increased their own risk exposure, nearly quadrupling it, although from a small base. The prudent risk exposure at the end of 2023 was 531 million euros.
