FEDS Paper: Pricing Tail Risks: Bank Equity Returns During the 2023 Bank Stress

09/05/2025 Federal Reserve Central banks

Matthew P. Seay and Shawn M. KimbleDid bank equity prices reflect growing sector imbalances before the 2023 failure of Silicon Valley Bank? We find that banks with higher reliance on uninsured deposits, or with higher marked-to-market leverage, had lower equity returns prior to SVB's collapse. Although markets priced uninsured deposits and high leverage individually, their interaction was not reflected in market prices prior to SVB’s failure.

IFDP Paper: De-Dollarization? Diversification? Exploring Central Bank Gold Purchases and the Dollar’s Role in International Reserves

09/05/2025 Federal Reserve Central banks

Colin WeissI examine how governments have managed their holdings of gold and dollar reserves in recent decades, a period when gold’s share of aggregate international reserves rose and the dollar’s share fell. Using data on central banks’ reserve currency composition and official sector purchases of U.S. assets, I argue that gold reserve accumulation is generally not associated with de-dollarization of international reserves at the country level, except in a few prominent cases.

IFDP Paper: Geopolitical Risk and Global Banking

08/27/2025 Federal Reserve Central banks

Friederike Niepmann and Leslie Sheng ShenHow do banks respond to geopolitical risk, and is this response distinct from other macroeconomic risks? Using U.S. supervisory data and new geopolitical risk indices, we show that banks reduce cross-border lending to countries with elevated geopolitical risk but continue lending to those markets through foreign affiliates—unlike their response to other macro risks.

FEDS Paper: When Tails Are Heavy: The Benefits of Variance-Targeted, Non-Gaussian, Quasi-Maximum Likelihood Estimation of GARCH Models

08/27/2025 Federal Reserve Central banks

Todd PronoIn heavy-tailed cases, variance targeting the Student's-t estimator proposed in Bollerslev (1987) for the linear GARCH model is shown to be robust to density misspecification, just like the popular Quasi-Maximum Likelihood Estimator (QMLE). The resulting Variance-Targeted, Non-Gaussian, Quasi-Maximum Likelihood Estimator (VTNGQMLE) is shown to possess a stable limit, albeit one that is highly non-Gaussian, with an ill-defined variance.

From words to deeds – incorporating climate risks into sovereign credit ratings

07/29/2025 European Central Bank Central banks

We investigate the impact of climate risks on sovereign credit ratings worldwide. Our analysis shows that higher temperature anomalies and more frequent natural disasters – measures of physical risk – correlate with lower credit ratings. We find that long-term shifts in climate patterns (“chronic risk”) primarily affect advanced economies, while the increased frequency and severity of extreme weather events (“acute risk”) matters more for emerging economies. However, the estimated impact of both types of risk on credit ratings is low and the economic effects are negligible.

Climate change, firms and aggregate productivity

06/24/2025 European Central Bank Central banks

Our paper uses a general equilibrium framework to examine the effects of temperature on firm-level demand, productivity and input allocative efficiency. Using data from Italian firms and detailed climate data, it uncovers a sizeable negative effect of extreme temperatures on firm-level productivity. Based on these estimates, the model generates aggregate productivity losses from local temperature fluctuations that are higher than previously thought, ranging from 0.60% to 6.82% depending on the scenario and the extent of adaptation.

Private safe asset supply and financial instability

05/27/2025 European Central Bank Central banks

This article studies the supply of private safe assets by banks and its implications for financial stability. Banks originate loans and improve loan quality through hidden screening efforts. They can then create safe assets by issuing debt backed by the safe payoffs, from both loans they have originated and a diversified pool of loans from other banks. The interaction between banks’ screening efforts and diversification decisions determines the volume of safe assets they supply.

Why monetary policy should crack down harder during high inflation

04/29/2025 European Central Bank Central banks

The recent surge in inflation has led to a significant increase in the frequency of price changes, making prices more flexible. Conventional models assume a constant price change frequency, but in state-dependent models the frequency varies with economic conditions. Price flexibility has an impact on the effectiveness of monetary policy. In high inflation periods, frequent price changes make monetary policy more effective in reducing inflation with less impact on economic activity. Therefore, monetary policy should be more aggressive during such periods to stabilise prices efficiently.

Effects of monetary policy on labour income: the role of the employer

03/26/2025 European Central Bank Central banks

This article investigates how firms transmit monetary policy shocks to individual labour market outcomes at both the intensive and extensive margins. Using matched employer-employee administrative data from Germany, we study the effects of monetary policy shocks on individual employment and of labour income conditioning on characteristics of workers and firms. First, we find that the employment of workers at young firms is especially sensitive to monetary policy shocks.
