Abstract
Do politics matter for macroprudential policy? I show that changes to macroprudential regulation exhibit a predictable electoral cycle in the run-up to 221 elections across 58 countries from 2000 through 2014. Policies restricting mortgages and consumer credit are systematically less likely to be tightened before elections during credit booms and economic expansions. Consistent with theories of opportunistic political cycles, this pattern is stronger when election outcomes are uncertain or in countries where political interference is more likely. In contrast to monetary policy, I find limited evidence that central banks are uniquely insulated from political cycles in macroprudential policy. These results suggest that political pressures may limit the ability of regulators to “lean against the wind.”

Abstract
I study the relation between shadow banking and financial stability in an economy in which banks are susceptible to self-fulfilling runs and in which government-backed deposit insurance is limited. Shadow banks issue only uninsured deposits while commercial banks issue both insured and uninsured deposits. The effect of shadow banking on financial stability is ambiguous and depends on the (exogenous) upper limit on insured deposits. If the upper limit on insured deposits is high, then the presence of a shadow banking sector is detrimental to financial stability; shadow banking creates systemic instability that would not be present if all deposits were held in the commercial banking sector. In contrast, if the upper limit on insured deposits is low, then the presence of a shadow banking sector is beneficial from a financial stability perspective; shadow banks absorb uninsured (and uninsurable) deposits from the commercial banking sector, thereby shielding commercial banks from runs. While runs may occur in the shadow banking sector, the situation without shadow banks and a larger amount of uninsured deposits held at commercial banks is worse.

Abstract
We study optimal capital requirement regulation in a dynamic quantitative model in which nonfinancial firms, as well as households, hold deposits. Firms hold deposits for precautionary reasons and to facilitate the acquisition of production inputs. Our theoretical analysis identifies a novel general equilibrium channel that operates through firms’ deposits and mitigates the cost of increasing capital requirements. We calibrate our model and find that the optimal capital requirement is 18.7% but only 13.6% in a comparable model in which only households hold deposits. Our novel channel accounts for most of the difference.

Abstract
Regulatory bank levies set incentives for banks to reduce leverage. At the same time, corporate income taxation makes funding through debt more attractive. In this paper, we explore how regulatory levies affect bank capital structure, depending on corporate income taxation. Based on bank balance sheet data from 2006 to 2014 for a panel of EU-banks, our analysis yields three main results: The introduction of bank levies leads to lower leverage as liabilities become more expensive. This effect is weaker the more elevated corporate income taxes are. In countries charging very high corporate income taxes, the incentives of bank levies to reduce leverage turn ineffective. Thus, bank levies can counteract the debt bias of taxation only partially.

Abstract
The paper investigates the life-cycle of the 2008-2009 financial crisis by linking the Macroeconomic Imbalance Procedure (MIP) Scoreboard of the European Commission to the crisis database of the European Systemic Risk Board (ESRB). The novelty of the analysis is that early warning capacity of MIP indicators is empirically tested in case of various crisis events case by case (i) Currency/Balance-of-Payment/Capital flow events, (ii) Sovereign crisis events, (iii) Banking crisis events and (iv) Significant asset price corrections in EU Member States. Furthermore, we contribute to the literature by studying the predicting power of the MIP Scoreboard in the identification of the overheating in the economy in advance of crises (preventive arm of the MIP). We found that the predictive power of the MIP Scoreboard may be twice as high to capture sovereign and Currency/Balance-of-Payment/Capital flow type of crisis events than its power to capture a banking crisis or serious asset price corrections. We confirm the results of earlier empirical studies that some MIP indicators perform relatively well (current account and net international position) in all specifications. A simple composite indicator based on the threshold breaches of MIP Scoreboard Indicators, performed in most cases as good as the best individual indicator, and hence could be considered as an input to a simple, rule based and accountable decision making.

Abstract
In this paper I study how the effects of nationally implemented macroprudential policy spill across borders via international lending. For a set of 157 countries, I estimate a gravity model applied to international banking where the use of different macroprudential policy measures enter as friction variables. My findings support the existence of cross-border spillovers from macroprudential policy. Moreover, I find that the overall effect from more macroprudential regulation is highly dependent on the income group of the countries in which banks operate: The effect is of opposite sign for advanced and for emerging economies. I argue that the difference may tell of banks having more opportunities for regulatory arbitrage in emerging market economies.

Abstract
It is challenging to explain the collapse in the price of subprime mortgage-backed securities (MBS) during the Financial Crisis of 2008, using the existing models of fire sale. I present a model to demonstrate that fire sales may happen even when there is a relatively sizable pool of natural buyers and in the absence of asymmetric information, due to a coordination failure among buyers: buyers’ waiting to trade at a lower price tomorrow, can lead to a collapse in the price and trade volume today. In particular, I show that when trade is decentralized and participation is endogenous, a medium level of asset demand and liquidity needs that are expected to increase over time create complementarity among buyers’ decisions to wait. This complementarity makes competitive markets prone to coordination failures and fire sales accompanied by a collapse in the trade volume. Fire sales may also be inefficient. I also discuss various policy options to eliminate the risk of fire sales in such a setup.

Abstract
This paper documents the use of derivatives by securitisation special purpose entities (SPEs), also known as financial vehicle corporations (FVCs), domiciled in Ireland using transaction-level data established by the European Market Infrastructure Regulation. We show that these entities primarily engaged in interest rate derivatives over the period of 2015-2017. We find that larger entities that already engage in international capital markets are more likely to have derivative exposures. We also show that entities sponsored by banks and non-bank financial institutions are relatively more likely to engage in derivative markets. The characteristics of these bank sponsors are important in determining SPEs' engagement in derivative markets. SPEs' heavy reliance on debt finance coupled with their strong interconnectedness with bank sponsors underscores the importance of continuous monitoring and macroprudential surveillance of their derivative activities.

Abstract
The funding mix of European firms is weighted heavily towards bank credit, which underscores the importance of efficient pass-through of monetary policy actions to lending rates faced by firms. Euro area pass-through has shifted from being relatively homogenous to being fragmented and incomplete since the financial crisis. Distressed loan books are a crisis hangover with direct implications for profitability, hampering banks ability to supply credit and lower loan pricing in response to reductions in the policy rate. This paper presents a parsimonious model to decompose the cost of lending and highlight the role of asset quality in diminishing pass-through. Using bank-level data over the period 2008-2014, we empirically test the implications of the model. We show that a one percentage point increase in the impairment ratio lowering short run pass-through by 3 percent. We find that banks with severely impaired balance sheets do not adjust their loan pricing in response to changes in the policy rate at all. We derive a measure of the hidden bad loan problem, the NPL gap, which we define as the excess of non-performing loans over impaired loans. We show that it played a significant role in the fragmentation of euro area pass-through post-crisis.

Abstract
The paper investigates the effectiveness of dividend-based macroprudential rules in complementing capital requirements to promote bank soundness and sustained lending over the cycle. First, some evidence on bank dividends and earnings in the euro area is presented. When shocks hit their profits, banks adjust retained earnings to smooth dividends. This generates bank equity and credit supply volatility. Then, a DSGE model with key financial frictions and a banking sector is developed to assess the virtues of what shall be called dividend prudential targets. Welfare-maximizing dividend-based macroprudential rules are shown to have important properties: (i) they are effective in smoothing the financial and the business cycle by means of less volatile bank retained earnings, (ii) they induce welfare gains associated to a Basel III-type of capital regulation, (iii) they mainly operate through their cyclical component, ensuring that long-run dividend payouts remain unaffected, (iv) they are flexible enough so as to allow bank managers to optimally deviate from the target (conditional on the payment of a sanction), and (v) they are associated to a sanctions regime that acts as an insurance scheme for the real economy.

Abstract
Exchange-traded funds (ETFs) are hybrid investment vehicles that track an index or a basket of assets, combine features of open-end and closed-end mutual funds, and are continuously traded on liquid markets. They are one of the most popular financial innovations in recent decades: ETFs have grown greatly in size, diversity, scope, complexity and market significance. Drawing on the growing literature in this area, this report assesses possible channels through which ETFs may affect systemic risk. The increasing availability of ETFs can affect investors’ behaviour, by allowing them to pursue new strategies to seek return, manage risk and access new asset classes. Such changes in investors’ behaviour may in turn impact the functioning of financial markets, particularly in times of market stress. Empirical research has so far identified three effects.

Abstract
We characterize policy interventions directed to minimize the cost to the deposit guarantee scheme and the taxpayers of banks with legacy problems. Non-performing loans (NPLs) with low and risky returns create a debt overhang that induces bank owners to forego profitable lending opportunities. NPL disposal requirements can restore the incentives to undertake new lending but, as they force bank owners to absorb losses, can also make them prefer the bank being resolved. For severe legacy problems, combining NPL disposal requirements with positive transfers is optimal and involves no conflict between minimizing the cost to the authority and maximizing overall surplus.

Abstract
Using a sample of more than 18,000 Undertakings for Collective Investment in Transferable Securities,or UCITS, this paper aims to provide a first overview of the use of credit default swaps by EU UCITSfunds. We show that UCITS funds only account for a small share of the overall EU credit derivativesmarket. The CDS market is highly concentrated, with thirteen large dealers acting as counterparty to thevast majority of CDS transactions that involve UCITS funds. The use of CDS by UCITS is mainlyconcentrated in fixed-income funds and funds that rely on so-called alternative strategies. Funds that useCDS tend to be much larger on average. The analysis also reveals three salient features in the UCITSfunds’ use of CDS. Firstly, funds with directional strategies, such as fixed-income and allocation funds (ormixed funds), are on aggregate net sellers of CDS. Secondly, a large majority of CDS underlyings areindices, from which funds can gain exposure to multiple entities at once within one sector or region.Lastly, most sovereign single-name CDS are written on emerging market issuers, highlighting the rolethat these instruments can play in facilitating access to less liquid markets.

Abstract
Regulatory action in response to the global financial crisis, together with broader developments in finance and society, have materially expanded regulation in the financial sector. While there is a general consensus on the need for regulation, there is much less agreement on whether recent increases in the complexity of regulation are necessary and appropriate. As a result, we are seeing a strong pushback from the financial industry, which is arguing that overly complex regulation has led to financial institutions becoming overburdened, hampering their ability to provide financial services efficiently.

Abstract
This paper revisits the credit spread puzzle for banks from the perspective of information contagion. The puzzle consists of two stylized facts: Structural determinants of credit risk not only have low explanatory power but also fail to capture common factors in the residuals. We reproduce the puzzle for European bank credit spreads and hypothesize that the puzzle exists because structural models ignore contagion effects. We therefore extend the structural approach to include information contagion through bank business model similarities. To capture this channel, we propose an intuitive measure for portfolio overlap and apply it to the complete asset holdings of the largest banks in the Eurozone. Incorporating this unique network information into the structural model increases explanatory power and removes a systemic common factor from the residuals. Furthermore, neglecting the network likely overstates the importance of structural determinants.

Abstract
We analyze the strategic interaction between undercapitalized banks and a supervisor who may intervene by preventive recapitalization. Supervisory forbearance emerges because of a commitment problem, reinforced by fiscal costs and constrained capacity. Private incentives to comply are lower when supervisors have lower credibility, especially for highly levered banks. Less credible supervisors (facing higher cost of intervention) end up intervening more banks, yet producing higher forbearance and systemic costs of bank distress. Importantly, when public intervention capacity is constrained, private recapitalization decisions become strategic complements, leading to equilibria with extremely high forbearance and high systemic costs of bank failure.

Abstract
Banks must make forward-looking provisions for loan losses under new international accounting standards introduced in 2018. In Europe, banks will assign performing exposures to a new “Stage 2” category with a higher provisioning penalty, if they have experienced significant increase in credit risk (SICR). We use a loan-level credit risk model and Irish residential mortgage panel data to assign performing loans into the appropriate stage. Using this technique, we characterise approximately 30 per cent of the performing Irish mortgage portfolio at end-2015 as Stage 2.We then calculate backward-looking, static estimations of Stage 2 mortgages between 2008 and 2015. This exercise suggests that loan stage assignment can be highly pro-cyclical. The share of Stage 2 among performing mortgages rises during the economic downturn to peak in 2013, after which large transitions are assigned from Stage 2 into lower-risk performing loans, as the economy improves.

Abstract
The paper evaluates the impact of a phased-in introduction of capital requirements on equity, risk-taking, and probability of default for a sample of European systemically important banks. Contrary to the case of a one-off introduction of capital requirements, this study does not find evidence of deleveraging through asset sales. A phased-in tightening promotes adjustment to lower leverage via an increase in equity thereby improving resilience and loss absorption capacity. The higher resilience comes at the cost of a portfolio reallocation towards riskier assets. Consistently with models on agency costs and gambling for resurrection, the risk-taking is driven by large and less profitable banks. The net impact on bank probabilities of default is positive albeit statistically insignificant, suggesting that risk-taking may crowd-out solvency.

Abstract
We study the impact of changes in regulations and policy interventions on systemic risk among European sovereign entities measured as volatility spillovers in respective credit risk markets. Our unique intraday CDS dataset allows for precise measurement of the effectiveness of these events in a network setting. In particular, it allows discerning interventions which entail significant changes in network cross-effects with appropriate bootstrap confidence intervals. We show that it was mainly regulatory changes with the ban of trading naked sovereign CDS in 2012 as well as the new ISDA regulations in 2014 which were most effective in reducing systemic risk. In comparison, we find that the effect of policy interventions was minor and generally not sustainable. In particular, they only had a significant impact when implemented for the first time and when targeting more than one country. For the volatility spillover channels, we generally find balanced networks with no fragmentation over time.

Abstract
Recent policy discussion includes the introduction of diversification requirements for sovereign bond portfolios of European banks. In this paper, we evaluate the possible effects of these constraints on risk and diversification in the sovereign bond portfolios of the major European banks. First, we capture the dependence structure of European countries' sovereign risks and identify the common factors driving European sovereign CDS spreads by means of an independent component analysis. We then analyze the risk and diversification in the sovereign bond portfolios of the largest European banks and discuss the role of “home bias”, i.e., the tendency of banks to concentrate their sovereign bond holdings in their domicile country. Finally, we evaluate the effect of diversification requirements on the tail risk of sovereign bond portfolios and quantify the system-wide losses in the presence of fire-sales. Under our assumptions about how banks respond to the new requirements, demanding that banks modify their holdings to increase their portfolio diversification may mitigate fire-sale externalities, but may be ineffective in reducing portfolio risk, including tail risk.

Abstract
We study determinants of sovereign portfolios of Spanish banks over a long time-span, starting in 2008. Our findings challenge the view that banks engaged in moral hazard strategies to exploit the regulatory treatment of sovereign exposures. In particular, we show that being a weakly capitalized bank is not related to higher holdings of domestic sovereign debt. While a strong link is present between central bank liquidity support and sovereign holdings, opportunistic strategies or reach-for-yield behavior appear to be limited to the non-domestic sovereign portfolio of well-capitalized banks, which might have taken advantage of their higher risk-bearing capacity to gain exposure (via central bank liquidity) to the set of riskier sovereign bonds. Furthermore, we document that financial fragmentation in EMU markets has played a key role in reshaping sovereign portfolios of banks. Overall, our results have important implications for the ongoing discussion on the optimal design of the risk-weighted capital framework of banks.

Abstract
Using household survey data, we document evidence of a loosening of credit standards in Euro area countries that experienced a property price boom-and-bust cycle. Borrowers in these countries exhibited significantly higher loan-to-value (LTV) and loan-to-income (LTI) ratios in the run up to the financial crisis, and an increasing tendency towards longer-term loans compared to borrowers in other countries. In recent years, despite the long period of historically low interest rates and substantial house price increases in some countries, we do not find similar credit easing as before the crisis. Instead, we find evidence of a considerable change in borrower characteristics since 2010: new borrowers are older and have higher incomes than before the crisis.
