- Abstract
- The aim of this article is to assess the scale and systemic nature of counterparty credit risk (CCR) stemming from banks’ derivatives activities and securities financing transactions. Using supervisory data, along with data collected from the EU-wide stress test carried out by the European Banking Authority in 2023, the article analyses the distribution of CCR across banks. It focuses on the concentration of risk within specific bank business models and products, and on links between the banking and NBFI sectors. It also examines not only the role of collateral in risk mitigation but also its potential negative impact on systemic risk. Exposures to CCR are concentrated in a group of global systemically important banks (G-SIBs) and investment banks, which play a vital intermediation role in European financial markets. Banks’s counterparties mainly operate in the non-bank financial intermediation (NBFI) sector. To quantify systemic risk in a network of CCR exposures, we use stress test techniques to see how widely hypothetical defaults among more vulnerable NBFI counterparties may spread across the banking system. In such an event, banks under European banking supervision may face considerable losses.

- Abstract
- The paper studies the central bank collateral framework and its impact on banks’ liquidity under an adverse stress test scenario. We construct a stress test model that accounts for a granular and multi-faceted representation of the liquidity of marketable and non-marketable assets. In particular, the model analyses banks’ strategic decisions to mobilise assets through four funding channels: unsecured loans, asset sales, private repurchase agreements, or Central Bank lending. We test three scenarios: the EBA regulatory stress test exercise, a shock to Russia and the Eastern European countries, and a shock to the Southern European countries. Results show that illiquidity can trigger insolvency and that liquidity adjustment can last significantly after the initial shock. We find evidence of a threshold in the benefits of expanding the collateral framework and highlight the heterogeneous effects across different jurisdictions and financial institutions. We find that bank equity losses are reduced in aggregate up to 17% at the tail of the loss distribution and on average by around 5% when financial institutions can rely on the collateral framework channel.

- Abstract
- Macroprudential policies should strengthen the banking sector throughout the financial cycle. However, while bank credit growth is used to capture cyclical exuberance and calibrate buffer requirements, it depends on potentially heterogeneous dynamics on the borrower and lender side. By decomposing credit growth into a common component and components capturing heterogeneity in supply and demand à la Amiti and Weinstein, 2018 applied on the euro area credit register ("AnaCredit"), we can inform the policy debates in two ways. Ex ante, we introduce a framework mapping the decomposition to different types of macroprudential instruments, specifically broad vs. targeted measures. Ex post, we also show that the resulting decomposition can be used to assess the effectiveness of adopted measures on credit supply or demand. We find evidence that buffer releases and credit guarantees increased bank credit supply during the COVID-19 pandemic and interacted positively with banks' profitability.
