Increase in personal contacts spurs economic activity
This summer the economic outlook in Germany is bright. As the pandemic is in retreat, the restrictions that have hampered many service activities are likely to be gradually lifted, and a strong boost in private purchases can be expected. The Halle Institute for Economic Research (IWH) forecasts that gross domestic product will increase by 3.9% in 2021 and by 4.0% in 2022. Production in East Germany is expected to increase by 3% in both years, respectively.

The Nexus between Loan Portfolio Size and Volatility: Does Bank Capital Regulation Matter?
Franziska Bremus, Melina Ludolph
Journal of Banking and Finance,
June
2021
Abstract
This paper analyzes the effects of bank capital regulation on the link between bank size and volatility. Using bank-level data for 27 advanced economies over the 2000–2014 period, we estimate a power law that relates the volume of a bank’s loan portfolio to the volatility of loan growth. Our analysis reveals, first, that more stringent capital regulation weakens the size-volatility nexus. Hence, in countries with more stringent capital regulation, large banks show, ceteris paribus, lower loan portfolio volatility. Second, the effect of tighter capital requirements on the size-volatility nexus becomes stronger for the upper tail of the bank size distribution. This is in line with capitalization decreasing with bank size, such that larger banks tend to be more affected by increasing capital requirements. Third, in countries with higher sectoral capital buffers, the size-volatility nexus is weaker.

The Impact of Risk-based Capital Rules for International Lending on Income Inequality: Global Evidence
Iftekhar Hasan, Gazi Hassan, Suk-Joong Kim, Eliza Wu
Economic Modelling,
May
2021
Abstract
This paper investigates the impact of international bank flows from G10 lender countries on income inequality in 74 borrower countries over 1999–2013. Specifically, we examine the role of international bank flows contingent upon the Basel 2 capital regulation and the level of financial market development in the borrower countries. First, we find that improvements in the borrower country risk weights due to rating upgrades under the Basel 2 framework significantly increase bank flows, leading to improvements in income inequality. Second, we find that the level of financial market development is also important. We report that a well-functioning financial market helps the poor access credit and thereby reduces inequality. Moreover, we employ threshold estimations to identify the thresholds for each of the financial development measures that borrower countries need to reach before realizing the potential reductions in income inequality from international bank financing.

Staggered Completion of the European Banking Union: Transposition Dates of the BRRD
Michael Koetter, Thomas Krause, Eleonora Sfrappini, Lena Tonzer
IWH Technical Reports,
2021
Abstract
In May 2014, the European Commission published the Bank Recovery and Resolution Directive (BRRD). The directive introduces rules on bank resolution and restructuring including a bailin tool. It constitutes the legal foundation underlying the Single Resolution Mechanism (SRM). Member countries of the European Union (EU) had to transpose this directive into national law by 31 December 2014 and implement the rules on resolution and restructuring of failing banks from 1 January 2015 onwards. However, many countries delayed the implementation. We assemble a dataset on national transposition dates of the BRRD across the EU-27 countries.

Completing the European Banking Union: Capital Cost Consequences for Credit Providers and Corporate Borrowers
Michael Koetter, Thomas Krause, Eleonora Sfrappini, Lena Tonzer
IWH Discussion Papers,
No. 4,
2021
Abstract
The bank recovery and resolution directive (BRRD) regulates the bail-in hierarchy to resolve distressed banks without burdening tax payers. We exploit the staggered implementation of the BRRD across 15 European Union (EU) member states to identify banks’ capital cost and capital structure responses. In a first stage, we show that average capital costs of banks increased. WACC hikes are lowest in the core countries of the European Monetary Union (EMU) compared to formerly stressed EMU and non-EMU countries. This pattern is driven by changes in the relative WACC weight of equity in response to the BRRD, which indicates enhanced financial system resilience. In a second stage, we document asymmetric transmission patterns of banks’ capital cost changes on to corporates’ borrowing terms. Only EMU banks located in core countries that exhibit higher WACC are those that also increase firms’ borrowing cost and contract credit supply. Hence, the BRRD had unintended consequences for selected segments of the real economy.

To Rent or not to Rent: A Household Finance Perspective on Berlin's Short-term Rental Regulation
Antonios Mavropoulos
IWH Discussion Papers,
No. 1,
2021
Abstract
With the increasing concerns that accompany the rising trends of house sharing economies, regulators impose new laws to counteract housing supply scarcity. In this paper, I investigate whether the ban on short-term entire house listings activated in Berlin in May 2016 had any adverse effects from a household finance perspective. More specifically, I derive short-term rental income and counter-factually compare it with long-term rental income to find that the ban, by decreasing the supply of short-term housing, accelerated short-term rental income but did not have any direct effect on long-term rental income. Commercial home-owners therefore would find renting on the short-term market to be financially advantageous.

A Note of Caution on Quantifying Banks' Recapitalization Effects
Felix Noth, Kirsten Schmidt, Lena Tonzer
Deutsche Bundesbank Discussion Paper,
No. 2,
2021
Abstract
Unconventional monetary policy measures like asset purchase programs aim to reduce certain securities' yield and alter financial institutions' investment behavior. These measures increase the institutions' market value of securities and add to their equity positions. We show that the extent of this recapitalization effect crucially depends on the securities' accounting and valuation methods, country-level regulation, and maturity structure. We argue that future research needs to consider these factors when quantifying banks' recapitalization effects and consequent changes in banks' lending decisions to the real sector.

Benign Neglect of Covenant Violations: Blissful Banking or Ignorant Monitoring
Stefano Colonnello, Michael Koetter, Moritz Stieglitz
Economic Inquiry,
No. 1,
2021
Abstract
Theoretically, bank's loan monitoring activity hinges critically on its capitalization. To proxy for monitoring intensity, we use changes in borrowers' investment following loan covenant violations, when creditors can intervene in the governance of the firm. Exploiting granular bank‐firm relationships observed in the syndicated loan market, we document substantial heterogeneity in monitoring across banks and through time. Better capitalized banks are more lenient monitors that intervene less with covenant violators. Importantly, this hands‐off approach is associated with improved borrowers' performance. Beyond enhancing financial resilience, regulation that requires banks to hold more capital may thus also mitigate the tightening of credit terms when firms experience shocks.

The Real Impact of Ratings-based Capital Rules on the Finance-Growth Nexus
Iftekhar Hasan, Gazi Hassan, Suk-Joong Kim, Eliza Wu
International Review of Financial Analysis,
January
2021
Abstract
We investigate whether ratings-based capital regulation has affected the finance-growth nexus via a foreign credit channel. Using quarterly data on short to medium term real GDP growth and cross-border bank lending flows from G-10 countries to 67 recipient countries, we find that since the implementation of Basel 2 capital rules, risk weight reductions mapped to sovereign credit rating upgrades have stimulated short-term economic growth in investment grade recipients but hampered growth in non-investment grade recipients. The impact of these rating upgrades is strongest in the first year and then reverses from the third year and onwards. On the other hand, there is a consistent and lasting negative impact of risk weight increases due to rating downgrades across all recipient countries. The adverse effects of ratings-based capital regulation on foreign bank credit supply and economic growth are compounded in countries with more corruption and less competitive banking sectors and are attenuated with greater political stability.

Why Life Insurers are Key to Economic Dynamism in Germany
Reint E. Gropp, William McShane
IWH Online,
No. 6,
2020
Abstract
Young entrepreneurial firms are of critical importance for innovation. But to bring their new ideas to the market, these startups depend on investors who understand and are willing to accept the risk associated with a new firm. Perhaps the key reason as to why the US has succeeded in producing nearly all the most successful new firms of the 21st century is the economy’s ability to supply vast sums of capital to promising startups. The volume of venture capital (VC) invested in the US is more than 60 times that of Germany. In this policy note, we argue that differences in the regulatory and structural context of institutional investors, in particular life insurance companies, is a central driver of the relative lack of VC - and thereby successful startups - in Germany.
