Inflation risk and heterogeneous trading down

11/25/2025 European Central Bank Central banks

I examine how households adjust the quality of their purchases in response to adverse economic shocks. Using household scanner data from Germany, I document heterogeneous responses across income levels. Higher-income households tend to reduce the quality of the goods they purchase, whereas lower-income households, who typically consume lower-quality goods, show a limited propensity to trade down, likely due to a limited ability to do so. To assess the equilibrium effects of an aggregate shift in demand toward lower-quality varieties, I implement a shift-share research design.

Systemic risks in linkages between banks and the non-bank financial sector

11/25/2025 European Central Bank Central banks

Linkages between euro area banks and entities in the non-bank financial intermediation (NBFI) sector may lead to the emergence of systemic risk in at least two fields. First, the banking sector receives short-term deposit, repo and debt securities liabilities from NBFI entities. Such liabilities may be prone to flight risk and difficult to substitute. Second, euro area banks provide credit to NBFI entities which follow leveraged investment strategies.

FEDS Paper: Settlement Speed and Financial Stability

11/20/2025 Federal Reserve Central banks

Agostino Capponi and Jin-Wook ChangThis paper investigates how settlement speed affects financial stability in payment networks, taking into account netting benefits, liquidity costs, and counterparty risks. Our analysis reveals that faster settlements have ambiguous effects on systemic risk and social welfare. The optimal settlement speed is determined by the network structure and the trade-off between netting efficiency and liquidity costs on one hand, and the probability of counterparty defaults on the other.

Walking the talk? Green politicians and pollution patterns

11/20/2025 European Central Bank Central banks

Exploiting three decades of detailed regional data for Germany, we find that when the Green Party is successful at the polls, local hazardous emissions decline. The level of political representation matters, too. Green politicians’ gaining influence at county level is followed largely by a decline in air pollutants that have an immediate adverse health effect. In contrast, when the Green party joins the state government, only greenhouse gas emissions that affect the welfare of future generations via climate change decline.

The complex linkages between euro area insurers and sovereign bond markets

11/20/2025 European Central Bank Central banks

Euro area insurers manage several trillion euro in assets and take a long‑term investment perspective. To counteract the long period of low interest rates, they have shifted towards holding more alternative and less liquid assets. As a result, their balance sheets have become less liquid and more sensitive to market conditions overall. Meanwhile, their holdings of sovereign bonds show a significant home bias, which may have even increased with quantitative easing.

FEDS Paper: The Collateral Channel and Bank Credit(Revised)

11/19/2025 Federal Reserve Central banks

Arun Gupta, Horacio Sapriza, and Vladimir YankovWe examine the firm-level and aggregate effects of the collateral channel using administrative bank-firm-loan level data. We introduce novel instrumental variables related to the efficiency of federal district bankruptcy courts and show their importance as predictors of collateral use and banks' expected losses given default across collateral types.

Beyond the single bank: macroprudential insights from the 2025 EU-wide stress test and its extensions

11/19/2025 European Central Bank Central banks

This overview article provides an introduction to the 2025 Macroprudential Stress Test Extension Report (MaSTER), released as the 32nd edition of the Macroprudential Bulletin, which investigates how the EU-wide stress test and its extensions provide a broader assessment of the systemic vulnerabilities of euro area banks. The 2025 EU-wide stress test results are expanded via a top-down model-based toolkit to assess additional risks, perform policy simulation exercises, and present novel approaches to gauging the severity of the adverse scenario.
