I propose a unified model of domestic bank runs, sovereign debt issuance and international reserve accumulation. Banking fragility gives rise to endogenous costs of default that support sovereign debt capacity. It additionally brings about a financial stabilization role for international...

I propose a dynamic general equilibrium model in which strategic interactions between banks and depositors may lead to endogenous bank fragility and slow recovery from crises. When banks' investment decisions are not contractible, depositors form expectations about bank risk-taking and demand a...

We develop a model of bank risk-taking with strategic sovereign default risk. Domestic banks invest in real projects and purchase government bonds. While an increase in bond purchases crowds out profitable investments, it improves the government's incentives to repay and therefore lowers its...

Episodes of debt accumulation have been a recurrent feature of the global economy over the past fifty years. Since 2010, emerging and developing economies have experienced another wave of historically large and rapid debt accumulation. Similar past debt buildups have often ended in widespread...

We analyze domestic, foreign, and central banks holdings of public debt for 31 countries for the period of 1989-2022, applying panel regressions and quantile analysis. We conclude that an increase in sovereign risk raises the share of domestic banks' portfolio of public debt and reduces the...

We examine the welfare effects of bailouts in economies exposed to sovereign default risk. When a government of a small open economy requests a bailout from an international financial institution, it receives a non-defaultable loan of size G that comes with imposed debt limits. The government...

We study determinants of sovereign portfolios of Spanish banks over a long time-span, starting in 2008. Our findings challenge the view that banks engaged in moral hazard strategies to exploit the regulatory treatment of sovereign exposures. In particular, we show that being a weakly capitalized...
