The emergence of so-called "decentralised finance" (DeFi) and a shadow financial system of cryptocurrency exchanges and stablecoin issuers raises the challenge of how to apply technology-neutral regulation so that similar risks are subject to the same rules. This paper makes the case for...

We study the efficiency of banking regulation under financial integration. Banks freely choose the jurisdiction where to locate their activities and have private information about their efficiency level. Regulators non-cooperatively offer any regulatory contract that satisfies information and...

This paper focuses on the consequences of cross-border banking and entry of multi-national banks (MNBs) for banking supervision and regulation. When a MNB expands internationally with subsidiaries, the MNB operates under the legislation of several countries - both the home country and the host...

Several countries have recently introduced national capital standards exceeding the internationally coordinated Basel III rules, thus suggesting a 'race to the top' in capital standards. We study regulatory competition when banks are heterogeneous and give loans to firms that produce output in...

We examine the fiscal footprint of macroprudential policy in euro area countries arising through the bond market channel (Reis, 2021). Using local projections, we estimate impulse responses of the fiscal balance to an unexpected tightening in macroprudential capital regulation. Our findings...

This paper models the strategic interaction between a rating agency, a bank and a bank regulator who lacks information about bank asset risk. The regulator can either (1) make bank capital requirements contingent on credit ratings; or (2) set rating-independent capital requirements. Truthful...

I analyze the optimal design of banking supervision in the presence of cross-border lending. Cross-border lending could imply that an individual bank failure in one country could trigger negative spillover effects in another country. Such cross-border contagion effects could turn out to be...

We present a network model of the interbank market in which optimizing risk averse banks lend to each other and invest in non-liquid assets. Market clearing takes place through a tâtonnement process which yields the equilibrium price, while traded quantities are determined by means of a...

This paper uses data from a panel of more than 400 Italian banks for the period 2001 - 2012 to examine the main determinants of loan loss provision (LLP), which are classified as either discretionary (income smoothing, capital management, signalling) or non-discretionary (related to the business...
