How Has COVID-19 Affected Banking System Vulnerability?
The COVID-19 pandemic has led to significant changes in banks’ balance sheets. To understand how these changes have affected the stability of the U.S. banking system, we provide an update of four analytical models that aim to capture different aspects of banking system vulnerability.

Assessing Contagion Risk in a Financial Network
Since the 2008 financial crisis, there has been an explosion of research trying to understand and quantify the default spillovers that can arise through counterparty risk. This first of two posts delves into the analysis of financial network contagion through this spillover channel. The authors introduce a framework, originally developed by Eisenberg and Noe, that is useful for thinking about default cascades.

How to escape a liquidity trap with interest rate rules
I study how central banks should communicate monetary policy in liquidity trap scenarios in which the zero lower bound on nominal interest rates is binding. Using a standard New Keynesian model, I argue that the key to anchoring expectations and preventing self-fulfilling deflationary spirals is to promise to keep nominal interest rates pegged at zero for a length of time that depends on the state of the economy. I derive necessary and sufficient conditions for this type of state-contingent forward guidance to implement the welfare-maximizing equilibrium as a globally determinate (that is, ...

Fire-sale spillovers and systemic risk
We reveal and track over time the factors making the financial system vulnerable to fire sales by constructing an index of aggregate vulnerability. The index starts increasing in 2004, before any other major systemic risk measure, more than doubling by 2008. The fire-sale-specific factors of delevering speed and concentration of illiquid assets account for the majority of this increase. Individual banks? contributions to aggregate vulnerability are an excellent five-year-ahead predictor of SRISK, one of the most prominent systemic risk measures. Had our estimates been available at the time, ...

The equity risk premium: a review of models
We estimate the equity risk premium (ERP) by combining information from twenty models. The ERP in 2012 and 2013 reached heightened levels?of around 12 percent?not seen since the 1970s. We conclude that the high ERP was caused by unusually low Treasury yields.

The equity risk premium: a review of models
The authors estimate the equity risk premium (ERP)?the expected return on stocks in excess of the risk-free rate?by combining information from twenty models for the period 1960-2013. They begin their analysis by categorizing the models into five classes: trailing historical mean, dividend discount, cross-sectional estimation, regression analysis using valuation ratios or macroeconomic variables, and surveys. They find that an optimal weighted average of all models places the one-year-ahead ERP in June 2012 at 12.2 percent, close to levels reached in the mid- and late 1970s, when the ERP was ...

Time-Varying Inflation Risk and Stock Returns
We show that inflation risk is priced in stock returns and that inflation risk premia in the cross-section and the aggregate market vary over time, even changing sign as in the early 2000s. This time variation is due to both price and quantities of inflation risk changing over time. Using a consumption-based asset pricing model, we argue that inflation risk is priced because inflation predicts real consumption growth. The historical changes in this predictability and in stocks' inflation betas can account for the size, variability, predictability and sign reversals in inflation risk premia.

Monetary policy and financial conditions: a cross-country study
Loose financial conditions forecast high output growth and low output volatility up to six quarters into the future, generating time-varying downside risk to the output gap, which we measure by GDP-at-Risk (GaR). This finding is robust across countries, conditioning variables, and time periods. We study the implications for monetary policy in a reduced-form New Keynesian model with financial intermediaries that are subject to a Value at Risk (VaR) constraint. Optimal monetary policy depends on the magnitude of downside risk to GDP, as it impacts the consumption-savings decision via the Euler ...

On Fire-Sale Externalities, TARP Was Close to Optimal
Imagine that many large and levered banks suffer heavy losses and must quickly sell assets to reduce their leverage. We expect the market price of the assets sold to decline, at least temporarily. As a result, any other financial institutions that happen to hold the same assets will experience balance sheet losses through no fault of their own —a negative fire-sale externality. In this post, we show that the vulnerability to fire-sale externalities was high during the crisis and that the capital injections of the government’s Troubled Asset Relief Program (TARP) helped reduce it ...

Are Asset Managers Vulnerable to Fire Sales?
According to conventional wisdom, an open-ended investment fund that has a floating net asset value (NAV) and no leverage will never experience a run and hence never have to fire-sell assets. In that view, a decline in the value of the fund’s assets will just lead to a commensurate and automatic decline in the fund’s equity—end of story. In this post, we argue that the conventional wisdom is incomplete and then explore some of the systemic risk consequences of investment funds’ vulnerabilities to fire-sale spillovers.
