Recent years have seen renewed interest in the regulation of interbank markets. A review of the literature in this area identifies two gaps: first, the literature has tended to make ad hoc assumptions about the interbank contract space, which makes it difficult to generate convincing policy...

We propose a flexible machine learning (ML) framework for real-time transaction monitoring in high-value payment systems (HVPS), which are a central piece of a country's financial infrastructure. This framework can be used by system operators and overseers to detect anomalous transactions,...

Financial markets face the constant threat of cyber attacks. We develop a principal-agent model of cyber-attacking with fee-paying clients who delegate security decisions to financial platforms. We derive testable implications about clients' vulnerability to cyber attacks and about the fees...

High-value payment systems (HVPSs) are typically liquidity-intensive because the payment requests are indivisible and settled on a gross basis. Finding the right order in which payments should be processed to maximize the liquidity efficiency of these systems is an NP-hard combinatorial...

Banking regulators often practice forbearance and ambiguity in insolvency resolutions. The paper examines the effects of regulatory forbearance and ambiguity in a context of allocational efficiency. Bailouts, liquidations and their stochastic policy mix lead to suboptimal allocations if banks do...

Using a unique dataset of the Euro area and the U.S. bank lending standards, we find that low (monetary policy) short-term interest rates soften standards, for household and corporate loans. This softening – especially for mortgages – is amplified by securitization activity, weak supervision...

In the presence of macroeconomic shocks severe enough to threaten the liquidity or solvency of the banking system, the regulator can rely on the funds concentration effect to save long-term investment projects. Some banks are forced into bankruptcy with the result that other banks obtain more...
