- Abstract
- The digitalisation of payments has accelerated over the last decades with the internet and ever faster and cheaper computing. Now, many believe that decentralised finance (“DeFi”) offers fundamentally new possibilities for trading, payments and settlement. Moreover, for a few years central banks have launched work on what has been called retail and wholesale central bank digital currencies (“CBDC”). Concurrent to the rise of innovative technologies has been the advent of new terminology, which is widely used, but which often seems to be biased, confusing, or is used inconsistently. By providing an etymology of key concepts and reviewing terminology and definitions, this paper also provides a new approach to clarifying the essence of new technologies in the field of payments to facilitate ongoing discussions about their eventual merits and use cases.

- Abstract
- This paper explores the relationship between banks and stablecoins and their issuers, focusing on the mechanical effects on banks’ capital and liquidity ratios when issuing stablecoins or collecting deposits from stablecoin issuers.The analysis reveals that converting retail deposits into stablecoin issuers’ deposits weakens a bank’s liquidity coverage ratio (LCR), turning a retail deposit into a wholesale deposit, even when these funds are reinvested in high-quality liquid assets. If a credit institution issues its own stablecoins, the impact on its LCR depends on whether it can identify the stablecoin holders; unknown holders weaken the LCR which could incentivise banks to issue stablecoins where they can continually identify the holders to benefit from more favourable liquidity treatment. Additionally, banks must either hold the reserves backing the stablecoins as central bank reserves or reinvest them in low-risk assets, making these funds a less effective source for economic financing and maturity transformation compared with traditional retail deposits. The study also finds that when retail customers of bank A buy a stablecoin issued by a non-bank that keeps reserves at bank B, both banks could see an unexpected decline in their liquidity ratios, as bank A loses stable retail deposits and bank B gains volatile wholesale deposits. These insights are crucial to understanding the dynamics between banks and stablecoins in the evolving financial landscape.

- Abstract
- Custodians play a key but discrete role in the global financial market infrastructure. In Europe, they are licensed as “credit institutions ”, a legal requirement for European deposit-taking institutions, and therefore they face the same prudential requirements as “traditional” banks. However, their business model and risk profile are different from those of traditional banks since the core of their activity does not encompass balance sheet transformation and the associated risks.
