IFDP Paper: To Cap or Not to Cap? Energy Crises in a Currency Union

12/12/2025 Federal Reserve Central banks

Momo KomatsuDuring the energy crisis in 2022 some Euro Area countries introduced price caps on energy, while others did not, leading to about 30 percentage points higher energy inflation in uncapped countries. This paper investigates the trade-offs policymakers face with energy price caps in a two-country currency union model with shared energy supply. The cooperative, optimal outcome is for neither country to impose a price cap, since the cap is a costly market distortion.

IFDP Paper: Decoupling Dollar and Treasury Privilege

12/12/2025 Federal Reserve Central banks

Wenxin Du, Ritt Keerati, and Jesse SchregerWe document a strong decoupling between the convenience yield on the US Dollar and US Treasuries. We measure the convenience of the U.S. dollar using covered interest parity (CIP) deviations between risk-free bank rates, such as secured overnight rates since the benchmark reform. In parallel, we measure the convenience of U.S. Treasury bonds through CIP deviations between government bond yields.

IFDP Paper: Economic Diversity and the Resilience of Cities

12/12/2025 Federal Reserve Central banks

François de Soyres, Simon Fuchs, Illenin O. Kondo, and Helene MaghinWe develop a framework to assess how economic shocks affect local labor markets and worker welfare, with a focus on city-level economic diversity. Using detailed worker flow data across cities, sectors, and occupations, we construct theory-consistent welfare measures. Our approach combines a dynamic discrete choice model with a dual representation that captures both direct effects and the insurance value of local economic diversity.

Financial integration and the transmission of monetary policy in the euro area

12/10/2025 European Central Bank Central banks

We study how financial integration shapes the transmission of monetary policy to consumer prices and output in the euro area. Using local projections, we document that the effect of financial integration is continuous: greater integration systematically strengthens the pass-through of monetary policy. When integration falls to low levels—around the first quartile of its historical distribution— transmission to both prices and output becomes statistically and economically insignificant. The amplification pattern is pervasive across member states and more pronounced in peripheral economies.

The climate-biodiversity-pollution nexus: the pricing of environmental credit risks for European

12/09/2025 European Central Bank Central banks

This study examines how euro area banks factor pollution-induced biodiversity risks into lending decisions, using data from 832 banks and 5,000 major polluters. Our results show that banks are increasingly pricing these risks by adjusting loan-to-value ratios and interest rates. Banks adjust lending conditions in line with EU pollution and biodiversity protection legislation, particularly for companies with large pollution footprints near biodiversity-protected areas or those contributing to Environmental Quality Standards failures of downstream surface waters.
