Trading for Bailouts

Staff Working Paper 2020-23 Toni Ahnert, Caio Machado, Ana Elisa Pereira
In times of high uncertainty, governments often implement interventions such as bailouts to financial institutions. To use public resources efficiently and to avoid major spillovers to the rest of the economy, policy-makers try to identify which institutions should receive assistance.

Loan Insurance, Market Liquidity, and Lending Standards

Staff Working Paper 2019-47 Toni Ahnert, Martin Kuncl
We examine loan insurance—credit risk transfer upon origination—in a model in which lenders can screen, learn loan quality over time, and can sell loans. Some lenders with low screening ability insure, benefiting from higher market liquidity of insured loans while forgoing the option to exploit future information about loan quality.

Bank Runs, Portfolio Choice, and Liquidity Provision

Staff Working Paper 2019-37 Toni Ahnert, Mahmoud Elamin
After the financial crisis of 2007–09, many jurisdictions introduced new banking regulations to make banks more resilient and less likely to fail. These regulations included tighter limits for the quality and quantity of bank capital and introduced minimum standards for liquidity. But what was the impact of these changes?

Macroprudential FX Regulations: Shifting the Snowbanks of FX Vulnerability?

Staff Working Paper 2018-55 Toni Ahnert, Kristin Forbes, Christian Friedrich, Dennis Reinhardt
Can macroprudential foreign exchange (FX) regulations on banks reduce the financial and macroeconomic vulnerabilities created by borrowing in foreign currency? To evaluate the effectiveness and unintended consequences of macroprudential FX regulations, we develop a parsimonious model of bank and market lending in domestic and foreign currency and derive four predictions.

Should Bank Capital Regulation Be Risk Sensitive?

Staff Working Paper 2018-48 Toni Ahnert, James Chapman, Carolyn A. Wilkins
We present a simple model to study the risk sensitivity of capital regulation. A banker funds investment with uninsured deposits and costly capital, where capital resolves a moral hazard problem in the banker’s choice of risk.

Seeking Safety

Staff Working Paper 2018-41 Toni Ahnert, Enrico Perotti
The scale of safe assets suggests a structural demand for a safe wealth share beyond transaction and liquidity roles. We study how investors achieve a reference wealth level by combining self-insurance and contingent liquidation of investment. Intermediaries improve upon autarky, insuring investors with poor self-insurance and limiting liquidation.

Asset Encumbrance, Bank Funding and Financial Fragility

Staff Working Paper 2016-16 Kartik Anand, Prasanna Gai, James Chapman, Toni Ahnert
In this piece we show that a limit on the level of asset encumbrance and minimum capital requirements are effective tools for minimizing the incentive for banks to take excessive risk.

Covered Bonds as a Source of Funding for Banks’ Mortgage Portfolios

Financial System Review - June 2018 Toni Ahnert
The author traces developments in the Canadian covered bond market. Covered bonds could be a valuable way to provide a stable and diverse source of funding, particularly for smaller banks. However, higher issuance could increase banks’ vulnerability to liquidity stress, with implications for the broader financial system. The author argues that these benefits and challenges can be balanced in a well-designed policy framework.
