Abstract
Energy sector firms use energy derivatives under different strategies depending on their main area of activity, business model and exposure to risk in physical markets. The significant volatility and skyrocketing prices seen in energy markets since March 2022 have resulted in large margin calls, generating liquidity risks for derivatives users. Strategies employed by companies to alleviate liquidity stress may lead to an accumulation of credit risk for their lenders or their counterparties in less collateralised segments of the derivatives market. Further price increases would accentuate nascent vulnerabilities, creating additional stress in a concentrated market. These issues underline the need to review margining practices and enhance the liquidity preparedness of all market participants to deal with large margin calls.

Abstract
Interest rate swaps account for the largest share of the euro area derivatives market. Outstanding contracts on EURIBOR swaps have risen sharply since 2021, possibly reflecting expectations of monetary policy normalisation. Using trade repository data on individual EURIBOR swap trades between 2019 and 2022, this box identifies how the risk is being shared across sectors in the interest rate swaps market and who would pay margins to whom should rates change. Empirical findings show that euro area banks are among the most active counterparties in EURIBOR swaps, due to either their role as market-makers or their need to hedge interest rate risk. Investment funds, insurance companies and pension funds would need to make margin payments in the event of rising interest rates.

Abstract
Since the European Central Bank’s (ECB’s) 2003 strategy review, the importance of macro-financial amplification channels for monetary policy has increasingly gained recognition. This paper takes stock of this evolution and discusses the desirability of further incremental enhancements in the role of financial stability considerations in the ECB’s monetary policy strategy. The paper starts with the premise that macroprudential policy, along with microprudential supervision, is the first line of defence against the build-up of financial imbalances. It also recognises that the pursuit of price stability through monetary policy, and of financial stability through macroprudential policy, are to a large extent complementary. Nevertheless, macroprudential policy may not be able to ensure financial stability independently of monetary policy, because of spillovers originating from the common transmission channels through which the two policies produce their effects. For example, a low interest rate environment can create incentives to engage in more risk-taking, or can adversely impact the profitability of financial intermediaries and hence their capacity to absorb shocks. The paper argues that the existence of such spillovers creates a conceptual case for monetary policy to take financial stability considerations into account. It then goes on to discuss what this conclusion might imply in practice for the ECB. One option would be to exploit the flexible length of the medium-term horizon over which price stability is to be achieved. Longer deviations from price stability could occasionally be tolerated, if they resulted in materially lower risks for financial stability and, ultimately, for future price stability. ...

Abstract
This paper shows how the combined endogenous reaction of banks and investment funds to an exogenous shock can amplify or dampen losses to the financial system compared to results from single-sector stress testing models. We build a new model of contagion propagation using a very large and granular data set for the euro area. Based on the economic shock caused by the Covid-19 outbreak, we model three sources of exogenous shocks: a default shock, a market shock and a redemption shock. Our contagion mechanism operates through a dual channel of liquidity and solvency risk. The joint modelling of banks and funds provides new insights for the assessment of financial stability risks. Our analysis reveals that adding the fund sector to our model for banks leads to additional losses through fire sales and a further depletion of banks’ capital ratios by around one percentage point.

Abstract
We examine some aspects of how the low-for-even-longer interest rate environment may affect bank lending margins and overall financial stability. We find evidence that margins fall more in response to declines in nominal short-term rates when these are low to begin with. The compression of margins reflects the sluggish response to further policy rate cuts of deposit rates as these approach the zero lower bound. Moreover, the analysis indicates that bank margins and overall profitability are influenced by both the level of real rates and, more materially, the level of inflation expectations embedded in nominal rates, which reflects the fact that bank profits are partly akin to seigniorage.

Abstract
Recent events have shown that stress in non-banks can affect other parts of the financial system, for example through forced asset sales and reduced short-term funding. This box examines the interconnections between banks and non-banks through direct exposures, overlapping portfolios and ownership links, and considers how these can increase the risk of systemic contagion.
