• The Prudential Toolkit with Shadow Banking

  Staff Working Paper 2025-9 Kinda Hachem, Martin Kuncl

  Can regulators keep pace with banks’ creative regulatory workarounds? Our analysis unpacks the trade-offs between fixed regulations and crisis-triggered rules, showing that the latter are especially prone to circumvention—and can trigger larger, costlier bailouts.

• Stagflation and Topsy-Turvy Capital Flows

  Staff Working Paper 2022-46 Julien Bengui, Louphou Coulibaly

  Unregulated capital flows are likely excessive during a stagflation episode, owing to a macroeconomic externality operating through the economy’s supply side. Inflows raise domestic wages and cause unwelcome upward pressure on firm costs, yet market forces likely generate such inflows. Optimal capital flow management instead requires net outflows.

• Are Bank Bailouts Welfare Improving?

  Staff Working Paper 2021-56 Malik Shukayev, Alexander Ueberfeldt

  Financial sector bailouts, while potentially beneficial during a crisis, might lead to excessive risk taking if anticipated. Taking expectations and aggregate risk implications into account, we show that bailouts can be welfare improving, but only if capital adequacy constraints are sufficiently tight.

• A Macroprudential Theory of Foreign Reserve Accumulation

  Staff Working Paper 2019-43 Fernando Arce, Julien Bengui, Javier Bianchi

  This paper proposes a theory of foreign reserves as macroprudential policy. We study an open-economy model of financial crises in which pecuniary externalities lead to overborrowing, and show that by accumulating international reserves, the government can achieve the constrained-efficient allocation.
