We model a banking union of two countries whose banking sectors differ in their average probability of failure and externalities between the two countries arise from cross-border bank ownership. The two countries face (i) a regulatory decision of which banks are to be shut down before they can...

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 analyze link between mortgage-related regulatory penalties levied on banks and the level of systemic risk in the U.S. banking industry. We employ a frequency decomposition of volatility spillovers (connectedness) to assess system-wide risk transmission with short-, medium-, and long-term...

Small businesses (SMEs) depend on banks for credit. We show that the severity of the Eurozone crisis was worse in countries where firms borrowed more from domestic banks ("domestic bank dependence") than in countries where firms borrowed more from international banks. Eurozone banking...

European banks have been criticized for holding excessive domestic government debt during the recent Eurozone crisis, which may have intensified the diabolic loop between sovereign and bank credit risks. By using a novel bank-level dataset covering the entire timeline of the Eurozone crisis, I...

We develop a simple model of banking regulation with two policy instruments: minimum capital requirements and supervision of domestic banks. The regulator faces a trade-off: high capital requirements cause a drop in the banks'; profitability, while strict supervision reduces the scope of...

The financial integration in Europe concentrates on cross-border mergers rather than cross-border lending and emphasizes the need for harmonizing bank regulation and supervision. We study the impact of cross-border lending in a theoretical model where banks acquire either hard or soft...

There are, at least, seven aspects relating to financial regulation where the recent, and still current, financial turmoil has thrown up issues for discussion. These include: 1. The scale and scope of deposit insurance; 2. Bank insolvency regimes, also known as prompt corrective action'; 3. Money...

During the last decades a consensus has emerged that it is impossible to disentangle liquidity shocks from solvency shocks. As a consequence the classical lender of last resort rules, as defined by Thornton and Bagehot, based on lending to solvent illiquid institutions appear ill-suited to this...

I review the state of the art of the academic theoretical and empirical literature on the potential trade-off between competition and stability in banking. There are two basic channels through which competition may increase instability: by exacerbating the coordination problem of...
