- Abstract
- We use transaction-level data on the euro area repo market to assess the impact of the Financial Stability Board’s (FSB) recommended minimum haircut framework on leverage in non-bank financial institutions. We find that it would affect larger and more leveraged entities the most, indicating its capability to make a meaningful contribution to addressing risks from leverage in non-bank financial institutions.

- Abstract
- This article develops a framework for assessing risks and formulating policies for leveraged alternative investment funds by integrating entity-level information for investment funds with transaction-level data on derivatives and repurchase agreements. Combining both types of data allows us to better understand the use of leverage in alternative investment funds and assess its implications for financial stability. Using a comprehensive set of risk metrics, our analysis identifies hedge funds and liability-driven investment (LDI) funds as the most vulnerable to leverage-related risks. We demonstrate the usefulness of our framework for risk assessment by analysing the sensitivity of leveraged funds to interest rate shocks. We find that LDI funds may face significant liquidity needs and mark-to-market losses. Hedge funds appear to be more resilient to this type of shock, but depending on their investment strategy, they could be sensitive to other risk factors. Our framework allows us to flexibly analyse other risk scenarios and to evaluate regulatory measures in terms of both their effectiveness and their precision in addressing potential vulnerabilities arising from leverage.

- Abstract
- Leverage in the non-bank financial intermediation (NBFI) sector can be a source of systemic risk and amplify stress in the wider financial system. Policymakers are currently considering ways to address NBFI leverage risks, with the focus on containing the build-up of such risks ex ante. To achieve this, authorities need a broad toolkit that allows them first to identify leverage risks and then to address them. Taking advantage of recent improvements in data availability, this edition of the Macroprudential Bulletin explores novel approaches to identifying risks and designing policies. In doing so, it contributes to the wider ongoing debate on addressing risks from NBFI leverage.

- Abstract
- Amid the growing financial vulnerabilities posed by climate change, we investigate macroprudential capital buffers to mitigate systemic risks and increase the resilience of the banking sector. Leveraging granular data and state-of-the-art stress testing methods, we quantify potential bank losses attributed to climate-related transition risks. Focusing on short-term transition scenarios, we document a significant variance among banks in their risk exposure, with the most exposed institutions being those characterized by lower excess capital. Subsequently, we introduce a methodological framework for tailoring bank-specific buffer requirements to cover these losses, offering macroprudential authorities a practical method for calibrating climate-related macroprudential capital buffers, complementing microprudential policies. While we focus our application on transition risks, the framework can be extended to capture all climate risks in general. The study demonstrates the potential of macroprudential capital buffers to mitigate potential climate-related losses and contributes to the understanding of the appropriate prudential policy response to these challenges.

- Abstract
- Recent stress episodes have shown how leverage in the non-bank financial intermediation (NBFI) sector can be a source of systemic risk and amplify stress in the wider financial system. Prominent examples of leverage-related risk in the NBFI sector include the role of leveraged hedge funds in the US Treasury market in March 2020, liability-driven investment funds in UK gilt markets in September 2022 and the failure of Archegos Capital Management in March 2021. In response to these events, policymakers around the world have launched a range of initiatives to contain risks from leverage in the NBFI sector more broadly. A key takeaway from these recent experiences and policy initiatives is that no single tool can be uniformly applied to address risks stemming from NBFI leverage. An effective policy response requires a broad range of tools to be made available, which should be appropriately tailored to the specific circumstances and can serve as complements to each other. Given the significant cross-border and cross-sector dimension of these risks, close coordination and cooperation between various authorities is essential, ensuring that risks are addressed from a system-wide perspective.

- Abstract
- The introduction of the Securities Financing Transactions Regulation into EU law provides a unique opportunity to obtain an in-depth understanding of repo markets. Based on the transaction-level data reported under the regulation, this paper presents an overview and key facts about the euro area repo market. We start by providing a description of the dataset, including its regulatory background, as well as highlighting some of its advantages for financial stability analysis. We then go on to present three sets of findings that are highly relevant to financial stability and focus on the dimensions of the different market segments, counterparties, and collateral, including haircut practices. Finally, we outline how the data reported under the regulation can support the policy work of central banks and supervisory authorities. We demonstrate that these data can be used to make several important contributions to enhancing our understanding of the repo market from a financial stability perspective, ultimately assisting international efforts to increase repo market resilience.

- Abstract
- Climate-related risks are due to increase in coming years and can pose serious threats to financial stability. This paper, by means of a DSGE model including heterogeneous firms and banks, financial frictions and prudential regulation, first shows the need of climate-related capital requirements in the existing prudential framework. Indeed, we find that without specific climate prudential policies, transition risk can generate excessive risk-taking by banks, which in turn increases the volatility of lending and output. We further show that relying on microprudential regulation alone would not be enough to account for the systemic dimension of transition risk. Implementing macroprudential policies in addition to microprudential regulation, leads to a Pareto improvement.

- Abstract
- This paper investigates both the magnitude and the drivers of bank window dressing behaviour in euro-denominated repo markets. Using a confidential transaction-level data set, our analysis illustrates that banks engineer an economically sizeable contraction in their repo transactions around regulatory reporting dates. We establish a causal link between these reductions and banks’ incentives to window dress and document the role of the leverage ratio and the G-SIB framework as the most relevant drivers of window dressing behaviour. Our findings suggest that regulatory action is warranted to limit banks’ ability to window dress.

- Abstract
- This box investigates the measurement of banks’ exposures to concentration risk related to climate change. It does so by introducing a new metric to quantify carbon-related concentration risk in banks’ corporate loan portfolios. Using data on individual borrowers’ emissions, the formula of the Herfindahl-Hirschman Index (HHI) is extended to create a carbon-weighted HHI (cwHHI). The cwHHI reveals substantial heterogeneity in the degree of carbon-related concentration among portfolios similarly exposed to high-emitting firms. Furthermore, banks with exposures to high-emitting firms similar to their peers but with higher cwHHI experience higher expected losses in a disorderly transition scenario. The empirical findings of this box suggest that institutions and exposures significantly affected by carbon-related concentration risk run a higher risk of incurring losses, extending even to those banks with a lower share of exposures to high emitters. The implication is that carbon-related concentration risk may be a material risk driver.

- Abstract
- The market turmoil in March 2020 highlighted key vulnerabilities in the EU money market fund (MMF) sector. This paper assesses the effectiveness of the EU's regulatory framework from a financial stability perspective, based on a panel analysis of EU MMFs at a daily frequency. First, we find that investment in private debt assets exposes MMFs to liquidity risk. Second, we find that low volatility net asset value (LVNAV) funds, which invest in non-public debt assets while offering a stable NAV, face higher redemptions than other fund types. The risk of breaching the regulatory NAV limit may have incentivised outflows among some LVNAV investors in March 2020. Third, MMFs with lower levels of liquidity buffers use their buffers less than other funds, suggesting low levels of buffer usability in stress periods. Our findings suggest fragility in the EU MMF sector and call for a strengthened regulatory framework of private debt MMFs.

- Abstract
- This impact assessment shows that a mandatory public debt holding would reduce the liquidity risk of private debt money market funds by increasing their shock absorption capacity and diversifying their asset liquidity profile. This would enable these funds to better mitigate the externalities associated with large-scale redemptions. The analysis also considers possible costs related to the funding of non-financial corporations and the attractiveness of MMFs as well as possible feasibility issues in terms of the supply of public debt.

- Abstract
- This article assesses proposed reforms to the European Money Market Funds (MMF) Regulation to enhance the resilience of the sector. Specifically, the article provides a rationale for requiring private debt MMFs to hold higher levels of liquid assets, of which a part should be public debt, and considers the design and calibration of such a requirement. The article also proposes that the impediments to the use of liquidity buffers should be removed and authorities should have a role in releasing these buffers. Finally, while the removal of a stable net asset value for low-volatility MMFs would reduce cliff effects, we argue that this might not be necessary if liquidity requirements for these private debt MMFs are sufficiently strengthened.

- Abstract
- Large differences between the liquidity of investment funds’ assets and liabilities (i.e. liquidity mismatches) can create vulnerabilities in the financial system and expose funds to a risk of large outflows and sudden drops in market liquidity. From a macroprudential perspective, the current regulatory framework may not sufficiently address the risks stemming from liquidity mismatches in investment funds. By modelling the liquidity management of an open-ended fund, this article provides theoretical justification for pre-emptive policy measures such as cash buffers that enhance financial stability by helping to increase the resilience of investment funds.

- Abstract
- Following the onset of the coronavirus (COVID‑19) crisis, a significant number of European investment funds suspended redemptions. We find that many of those funds had invested in illiquid assets, were leveraged or had lower cash holdings than funds that were not suspended. Furthermore, suspensions were more likely to be seen in jurisdictions where pre-emptive liquidity measures were not available. Our findings also suggest that suspensions have spillover effects on other funds and sectors, highlighting the importance of pre-emptive liquidity management measures.

- The turmoil seen in March 2020 highlighted key vulnerabilities in the money market fund (MMF) sector. This article assesses the effectiveness of the EU’s regulatory framework from a financial stability perspective and identifies three important lessons. First, investment in non-public debt assets exposes MMFs to liquidity risk, highlighting the need to limit investment in illiquid assets. Second, low-volatility net asset value (LVNAV) funds are particularly vulnerable to liquidity shocks, given that they invest in non-public debt assets while offering a stable net asset value (NAV). Enhanced portfolio requirements could strengthen their liquidity profile. And third, MMFs seem reluctant to draw down on their liquidity buffers during periods of stress, suggesting a need to make buffers more usable.

- Abstract
- During the market turmoil of March 2020, many money market funds (MMFs) and other investment funds which were exposed to liquidity risk through a liquidity mismatch between their assets and liabilities experienced significant outflows. Those funds reacted in a procyclical manner by either selling assets in already stressed markets or curtailing investors’ access. That behaviour resulted in knock-on effects on other sectors of the economy and amplified the stress within the financial system. This overview article discusses financial stability risks arising from liquidity transformation by MMFs and other investment funds, a subject which is then explored in greater depth in the three other articles in this issue of the Macroprudential Bulletin. While the liquidity transformation carried out by investment funds serves an important economic function, by intermediating savings and real economy financing, it can also generate risks to financial stability. With this in mind, this article argues for a macroprudential approach to the regulation of investment funds to enhance their resilience and facilitate a stable provision of funding to the wider economy in both normal market conditions and periods of market stress.

- Abstract
- The analysis provides empirical evidence that repo market liquidity is an important determinant of bond market liquidity and arbitrage opportunities in swap markets. The first part of the analysis is concerned with the role of repo market liquidity in funding bonds used as collateral in repo transactions. It explores whether tense repo markets reduce the liquidity in bond markets. The second part examines how lower liquidity in repo markets hampers arbitrage in swap markets. The results presented show that repo markets support both bond market liquidity and swap market efficiency, highlighting their important role in financial markets.

- Abstract
- Initial margin (IM) reduces counterparty credit risk in derivative markets. Notwithstanding efforts to limit potential procyclical effects of IM-setting practices, there is an ongoing debate about whether the current framework sufficiently addresses this concern, in particular when Value-at-Risk (VaR) models are used for setting IM. This article provides further insights into this issue. First, using EMIR data, we provide an overview of outstanding IM in the euro area derivative market and identify the most relevant sectors for the exchange of IM. Second, using a VaR IM model in line with industry practice, we show that aggregate IM can potentially vary substantially over a long-term horizon. Finally, we show that an IM floor based on a standardised IM model could be an effective tool for reducing IM procyclicality.

- Abstract
- We assess the quantitative implications of collateral re-use on leverage, volatility, and welfare within an infinite-horizon asset-pricing model with heterogeneous agents. In our model, the ability of agents to reuse frees up collateral that can be used to back more transactions. Re-use thus contributes to the buildup of leverage and significantly increases volatility in financial markets. When introducing limits on re-use, we find that volatility is strictly decreasing as these limits become tighter, yet the impact on welfare is non-monotone. In the model, allowing for some re-use can improve welfare as it enables agents to share risk more effectively. Allowing re-use beyond intermediate levels, however, can lead to excessive leverage and lower welfare. So the analysis in this paper provides a rationale for limiting, yet not banning, re-use in financial markets.

- Abstract
- Over the last decade, exchange-traded funds (ETFs) have grown at a fast pace both globally and in the euro area. ETFs typically offer low-cost diversified investment opportunities for investors. ETF shares can be bought and sold at short notice, making them efficient and flexible instruments for trading and hedging purposes. At the same time, the wider use of ETFs may also come with a growing potential for transmission and amplification of risks in the financial system. This special feature focuses on two such channels arising from (i) liquidity risk in ETF primary and secondary markets and (ii) counterparty risk in ETFs using derivatives and those engaging in securities lending. While ETFs still only account for a small fraction of investment fund asset holdings, their growth has been strong, suggesting a need for close monitoring from a financial stability and regulatory perspective, including prospective interactions with other parts of the financial system.

- Abstract
- This article summarises the key findings from a counterfactual exercise where the effect of removing repo assets from the leverage ratio on banks’ default probabilities is considered. The findings suggest that granting such an exemption may have adverse effects on the stability of the financial system, even when measures are introduced to compensate for the decline in capital required by the leverage ratio framework. Increases in probabilities of default are mainly seen for larger banks which are more active in the repo market. Moreover, it is observed that the predictive power of the model improves when repo assets are included. Overall, the analysis in this article does not support a more lenient treatment of repo assets in the leverage ratio framework, e.g. by exempting them or allowing for more netting with repo liabilities or against high-quality government bonds.

- The rapid growth of the asset management sector over recent years has raised questions about the interaction between traditional banks and investment funds, as well as the drivers behind this trend. Our analysis contributes to this debate by shedding light on the implications of increased competition between the two sectors. We first examine how competition between banks and investment funds drives the risk profiles and market shares of these two sectors. In a second step, we assess whether and how capital requirements for banks influence the relative market shares of the two sectors, contributing to both the analysis of the drivers behind the structural developments in the euro area financial sector and the work on the evaluation of the impact of post-crisis reforms.

- Abstract
- Effectively functioning repo markets are of key importance for both financial stability and monetary policy, but the excessive use of repos may also be a source of systemic risk as witnessed during the recent financial crisis. Regulatory reforms introduced since the start of the crisis have aimed to contain systemic risk related to the excessive build-up of leverage and unstable funding, but recently some concerns have been raised about their potential effects on the functioning of the repo market. This special feature presents new evidence on the drivers of banks’ activity in the repo market with respect to regulatory reforms. In addition, it takes a closer look at the repo market structure and pricing dynamics, in particular around banks’ balance sheet reporting dates. While the observed volatility around reporting dates suggests that the calculation methodology for some regulatory metrics should be reviewed, overall, the findings indicate that unintended consequences of regulatory reforms on the provision of repo services by euro area banks have not been material.

- Abstract
- This paper addresses the tradeoff between additional loss-absorbing capacity and potentially higher bank risk-taking associated with the introduction of the Basel III Leverage Ratio. This is addressed in both a theoretical and empirical setting. Using a theoretical micro model, we show that a leverage ratio requirement can incentivise banks that are bound by it to increase their risk-taking. This increase in risk-taking however, should be more than outweighed by the benefits of higher capital and therefore increased lossabsorbing capacity, thereby leading to more stable banks. These theoretical predictions are tested and confirmed in an empirical analysis on a large sample of EU banks. Our baseline empirical model suggests that a leverage ratio requirement would lead to a significant decline in the distress probability of highly leveraged banks.

- Abstract
- Alternative investment funds (AIFs) in Europe operate without regulatory leverage limits. Competent authorities within the EU have the legal power to impose macroprudential leverage limits on AIFs, but no authority has implemented this tool so far. This joint European Central Bank-De Nederlandsche Bank (DNB) special feature (i) presents a macroprudential case for limiting the use of leverage by investment funds, (ii) develops a framework to inform the design and calibration of macroprudential leverage limits to contain the build-up of leverage-related systemic risks by AIFs, and (iii) discusses different design and calibration options. By way of example, it uses supervisory information on AIFs managed by asset managers based in the Netherlands. The article concludes by recommending a way forward to develop an EU-level framework for a harmonised implementation of macroprudential leverage limits for AIFs, which forms a key part of the agenda of the European Systemic Risk Board (ESRB) to develop macroprudential policy beyond banking.

- Abstract
- This paper investigates whether credit constraints in the US economy amplify the international propagation of US financial shocks. We model the dynamics of the US economy jointly with global macroeconomic and financial variables using a threshold vector autoregression. This model captures regime-specific dynamics conditional on the severity of credit constraints in the US economy. We identify three main episodes of tight credit in US financial history over the past thirty years. These occur in the late-1980s, in the early 2000s, and during the 2007-09 financial crisis. We find that US financial shocks are associated with a significant contraction in global economic activity in times of tight credit. By contrast, there is little impact of US financial shocks on the global economy in normal times. This asymmetry highlights an international dimension of the US financial accelerator mechanism.

- Abstract
- Financial institutions can build up leverage via the use of derivatives and securities financing transactions (SFTs). In order to limit the build-up of excessive leverage and the associated liquidity risks, as well as the pro-cyclical effects of margin and haircut setting practices, the macro-prudential toolkit needs to be extended. This special feature presents the general case for setting macro-prudential margins and haircuts using theoretical and empirical evidence on the effectiveness of various design options. Furthermore, it addresses implementation and governance issues that warrant attention when developing a macro-prudential framework for margins and haircuts. It concludes by recommending a way forward that is intended to inform the ongoing policy discussions at the European and international levels.

- The Basel III leverage ratio aims to constrain the build-up of excessive leverage in the banking system and to enhance bank stability. Concern has been raised, however, that the non-risk-based nature of the leverage ratio could incentivise banks to increase their risk-taking. This special feature presents theoretical considerations and empirical evidence for EU banks that a leverage ratio requirement should only lead to limited additional risk-taking relative to the induced benefits of increasing loss-absorbing capacity, thus resulting in more stable banks.

- In this paper we examine the quantitative effects of margin regulation on volatility in asset markets. We consider a general equilibrium infinite-horizon economy with heterogeneous agents and collateral constraints. There are two assets in the economy which can be used as collateral for short-term loans. For the first asset the margin requirement is exogenously regulated while the margin requirement for the second asset is determined endogenously. In our calibrated economy, the presence of collateral constraints leads to strong excess volatility. Thus, a regulation of margin requirements may have stabilizing effects. However, in line with the empirical evidence on margin regulation in U.S. stock markets, we show that changes in the regulation of one class of assets may have only small effects on these assets' return volatility if investors have access to another (unregulated) class of collateralizable assets to take up leverage. In contrast, a countercyclical margin regulation of all asset classes in the economy has a very strong dampening effect on asset return volatility.
