This paper studies the effects of government guarantees on the interconnection between banking and sovereign debt crises in a framework where both the banks and the government are fragile and the credibility and feasibility of the guarantees are determined endogenously. The analysis delivers...

We study a novel mechanism through which systemic risk, in the form of self-fulfilling runs, forces the banks to hoard liquidity. To this end, we develop an environment where banks offer insurance to their depositors against both idiosyncratic and aggregate real uncertainty, by holding a...

We propose a novel theory of banks' liquidity management and financial fragility. Banks hold liquidity and an illiquid productive asset, thereby engaging in maturity transformation, and insure their depositors against idiosyncratic and aggregate shocks. However, strategic complementarities in...

Shocks to banks' ability to raise liquidity at short notice can lead to depositor panics, as evidenced by recent bank failures. Why don't banks take a more active role in managing these risks? In a standard bank-run model, we show that risk management failures are most prevalent when exposures...

How far should capital requirements be raised in order to ensure a strong and resilient banking system without imposing undue costs on the real economy? Capital requirement increases make banks safer and are beneficial in the long run but also entail transition costs because their imposition...

We examine the optimal size and composition of banks’ total loss absorbing capacity (TLAC). Optimal size is driven by the trade-off between providing liquidity services through deposits and minimizing deadweight default costs. Optimal composition (equity vs. bail-in debt) is driven by the...
