- Abstract
- This paper discusses the impact that a retail central bank digital currency (CBDC) could have on the implementation of monetary policy. Monetary policy implementation could be affected if the introduction of the retail CBDC changes the volume of commercial bank deposits held by customers, which would, in turn, affect central bank reserves. While it is often assumed that customer deposits would decrease if a CBDC was introduced, we provide arguments why this is by no means clear cut and deposits could even increase. If bank deposits do decrease, banks would need to draw on, and therefore reduce, their central bank reserve holdings. Moreover, uncertainty as to the timing and extent of any conversions of deposits into CBDC might prompt banks to scale up their demand for central bank reserves in order to hold larger precautionary buffers. Consequently, central banks might need to adjust their reserve supply and other features of their monetary policy implementation, depending, for example, on whether they use a floor or a corridor system for monetary policy implementation. In the specific case of the digital euro, the features already envisaged for its design would make it possible to minimise the risk of negative consequences for monetary policy implementation.

- Abstract
- When a bank receives credit from the central bank, its Liquidity Coverage Ratio (LCR) changes. In most cases, the LCR increases. We investigate how this LCR boost from central bank credit affects banks’ behaviour, looking at the euro area during the Corona year 2020. Our theoretical and empirical analyses suggest that banks that get strong LCR boosts from central bank credit tend to take actions that reduce their LCRs. In this sense, banks consume their LCR boosts. In terms of policy conclusions, our analysis suggests that central bank credit operations can provide strong incentives for banks to take actions that reduce their LCRs. Such actions, which could include the provision of additional credit and a shortening of the maturity structure of the liabilities of the banks, plausibly have an impact on the real economy. As such, our analysis reveals what may be called a “LCR channel” of monetary policy transmission.

- Abstract
- This paper summarises the work done by Eurosystem staff in the context of the Strategy Review Seminar on Monetary Policy Instruments. More specifically, it focuses on the efficacy, efficiency and potential side effects of the key monetary policy instruments employed by the European Central Bank since 2014. The following main findings emerge from the analysis. First, instruments have been effective in easing financing conditions and supporting economic growth, employment and inflation. Second, considering the effective lower bound on policy rates, a combination of instruments is generally more efficient than relying on a single tool. Third, side effects have been generally contained so far, but they are found to vary over time and need to be closely monitored on an ongoing basis. Fourth, the monetary policy toolkit needs to remain innovative, diversified, and flexible, i.e. reviewed regularly to ensure that it remains fit for purpose against the backdrop of evolving financial and macroeconomic conditions.

- Abstract
- This paper summarises the outcomes of the analysis of the ECB Crypto-Assets Task Force. First, it proposes a characterisation of crypto-assets in the absence of a common definition and as a basis for the consistent analysis of this phenomenon. Second, it analyses recent developments in the crypto-assets market and unfolding links with financial markets and the economy. Finally, it assesses the potential impact of crypto-assets on monetary policy, payments and market infrastructures, and financial stability. The analysis shows that, in the current market, crypto-assets’ risks or potential implications are limited and/or manageable on the basis of the existing regulatory and oversight frameworks. However, this assessment is subject to change and should not prevent the ECB from continuing to monitor crypto-assets, raise awareness and develop preparedness.

- Abstract
- This paper provides an assessment of the impact of the covered bond purchase programme (hereafter referred to as the CBPP) relative to its policy objectives. The analysis presented on the impact of the CBPP on both the primary and secondary bond markets indicates that the Programme has been an effective policy instrument. It has contributed to: (i) a decline in money market term rates, (ii) an easing of funding conditions for credit institutions and enterprises, (iii) encouraging credit institutions to maintain and expand their lending to clients, and (iv) improving market liquidity in important segments of the private debt securities market. The paper also provides an overview of the investment strategy of the the Eurosystem with regard to the CBPP portfolio.

- Abstract
- Unsecured interbank money market rates such as the Euribor increased strongly with the start of the financial market turbulences in August 2007. There is clear evidence that these rates reached levels that cannot be explained alone by higher credit risk. This article presents this evidence and provides a theoretical explanation which refers to the funding liquidity risk of lenders in unsecured term money markets.

- Abstract
- A standard repurchase agreement between two counterparties is considered to examine the endogenous choice of collateral assets, the feasibility of secured lending, and welfare implications of the central bank's collateral framework. As an important innovation, we allow for two-sided counterparty risk. Our findings relate to empirical characteristics of repo transactions and have an immediate bearing on market developments since August 2007.

- Abstract
- This paper tries to contribute to the discussion on the role of securities settlement infrastructures for financial integration in Europe. It presents a model that can explain a well-known stylized fact of securities settlement, the surprisingly high fees charged by central securities depositories (CSDs) for settlement through links between CSDs. As the model turns out to provide a robust explanation for this stylized fact, it is then used to analyzes an important policy question, the welfare effects of mergers of CSDs.

- Abstract
- This paper addresses a very European issue, the consolidation of securities trading and settlement infrastructures. In a two-country model, we analyze welfare implications of different types of consolidation. We find that horizontal integration of settlement systems is better than vertical integration of exchanges and settlement systems, but vertical integration is still better than no consolidation. These findings have clear policy implications with regards to the highly fragmented European securities infrastructure.

- Abstract
- The competition between a central securities depository (CSD) and a custodian bank is analysed in a Stackelberg model. The CSD sets its prices first, the custodian bank follows. There are many investor banks each of which has to decide whether to use the service of the CSD or of the custodian bank. This decision depends on the prices and the investor bank's preferences for the inhomogeneous services of the two service providers. Since the custodian bank uses services provided by the CSD as input, the CSD can raise its rival's costs. However, due to network externalities, the CSD's equilibrium market share is not necessarily higher than socially optimal. This result has important policy implications that are related to a discussion currently taking place in the securities settlement industry.
