The issuance of retail central bank digital currency (CBDC) entails a transfer of risk from commercial banks to the central bank. While this paper does not provide an overall assessment on whether or not to issue a retail CBDC, it analyzes how different mechanisms to limit the risk transfer, such as an unattractive interest rate on retail CBDC, a quantity ceiling or preventing convertibility of cash and reserves into CBDC, have different effects on the ability of retail CBDC to fulfil its intended purposes. In particular, these mechanisms hinder the use of CBDC as a medium of exchange. Specific aspects of demand and challenges related to a potential retail CBDC in Switzerland, namely, a small open economy with a safe-haven currency and a low level of government debt, are discussed.
This paper aims at deriving the market's assessment as to whether banks worldwide still benefit from a Too Big To Fail (TBTF) subsidy. Such a subsidy reflects the market's expectation of government support in the event of a crisis and results in reduced funding costs for the benefiting bank. To capture this effect, we use two different extensions of the Merton (1974) framework. We find that large banks benefit from a TBTF subsidy, while large nonfinancial firms do not. This subsidy has declined somewhat since the Global Financial Crisis (GFC) but remains larger than before the crisis. These conclusions also hold when considering Contingent Convertible (CoCos) and bail-in bonds as fully loss-absorbing. Moreover, we find differences in the TBTF subsidy across jurisdictions and provide evidence that these can to a large extent be explained by differences in bank health.
