Will German banks earn their cost of capital?

Deutsche Bundesbank Discussion Paper No. 01/2017
Andreas Dombret, Yalin Gündüz, Jörg Rocholl (2017)
Subject(s): Economics, politics and business environment, Finance, accounting and corporate governance
Keyword(s): German banking sector, low interest period, profitability, hidden and open reserves
JEL Code(s): G21, G28

Research Question: This paper analyses the effect of a sustained period of low interest rates on the outlook for the German banking sector. Low interest rates provide a particular challenge for German banks, which are highly dependent on interest income and exhibit relatively high cost-income ratios. It is thus an open question whether German banks will manage to earn their cost of capital in this environment.
Contribution: We analyse the interest earnings from loans and the interest expenses for deposits, i.e. the core business interest margin of a bank. We consider different future interest rate scenarios and analyse the extent to which they cause a further narrowing of the core business interest margin. Finally, we test whether a special feature of German accounting standards could serve as a buffer in sustaining profitability for some time.
Results: Our results indicate that a sustained period of low interest rates will increase the pressure on the core business interest margin earned by German banks. Even if interest rates stayed constant at current levels, the core business interest margin of German banks would be reduced by 16% over the next four years. Moreover, this projected decline in the core business interest margin will result in only 20% of German banks earning a cost of capital of 8% by the end of this decade. However, by applying a special feature of German accounting standards and using hidden and open reserves, German banks may alleviate this decline to a certain extent.

Collateral, central bank repos, and systemic arbitrage

Swiss Finance Institute Research Paper No. 16-66
Jörg Rocholl, Falko Fecht, Kjell G. Nyborg, Jiri Woschitz (2016)
Subject(s): Economics, politics and business environment
Keyword(s): Collateral, repo, systemic arbitrage, central bank, collateral policy, banks, liquidity, interbank market, financial stability, financial fragmentation
JEL Code(s): G12, G21, E42, E51, E52, E58

Central banks are under increased scrutiny because of the rapid growth in, and composition of, their balance sheets. Therefore, understanding the processes that shape these balance sheets and their consequences is crucial. We contribute by studying an extensive dataset of banks’ liquidity uptake and pledged collateral in central bank repos. We document systemic arbitrage whereby banks funnel credit risk and low-quality collateral to the central bank. Weaker banks use lower quality collateral to demand disproportionately larger amounts of central bank money (liquidity). This holds both before and after the financial crisis and may contribute to financial fragility and fragmentation.

Loan officer incentives and the limits of hard information

AFA 2013 San Diego Meetings Paper
Tobias Berg, Manju Puri, Jörg Rocholl (2016)
Subject(s): Finance, accounting and corporate governance
Keyword(s): Consumer loans, loan officer incentives, hard information, information manipulation
JEL Code(s): G21

Banks have been subject to a wave of investigations regarding fraudulent behavior. Much of the discussion centers on manipulation of hard information by employees down the line, who missell mortgages due to flawed debt-to-income ratios or manipulate LIBOR and FX rates. Despite these prominent cases, little is known in the academic literature as to whether and how manipulation of hard information is affected by incentives of these employees, and if anything there is increasing reliance on quantitative, hard information based models for regulating banks. In this paper, we fill this gap by analyzing almost a quarter million of retail loan applications. We show that loan officer incentives significantly skew ratings even in settings where ratings are computed using hard information only. These incentives have a first-order effect on bank profitability. Our results suggest that ratings are subject to the Lucas critique: Incentives influence the hard information reported by loan officers and thus change the link between hard information and default probabilities.

Institutional investors and corporate political activism

European Corporate Governance Institute (ECGI) - Finance Working Paper No. 470
Jörg Rocholl, Lei Zicheng, Rui A. Albuquerque, Chendi Zhang (2016)
Subject(s): Economics, politics and business environment, Finance, accounting and corporate governance
Keyword(s): Institutional Investors, Political Activism, Political Contributions, Political Connections, Citizens United
JEL Code(s): G14, G30

The landmark decision by the U.S. Supreme Court on Citizens United v. Federal Election Commission asserts for the first time that corporations benefit from First Amendment protection regarding freedom of speech in the form of independent political expenditures, thus creating a new avenue for political activism. This paper studies how corporations adjusted their political activism in response to this ruling. The paper presents evidence consistent with the hypothesis that institutional investors, in particular public pension funds, have a preference for not using the new avenue for political activism, a preference not shared by other investors.

Government guarantees and bank risk taking incentives

ESMT Working Paper No. 14-02 and CESifo Working Paper 4706
Markus Fischer, Christa Hainz, Jörg Rocholl, Sascha Steffen (2014)
Subject(s): Finance, accounting and corporate governance
Keyword(s): Government guarantees, exits, risk taking, franchise value, financial crisis, loans
JEL Code(s): G20, G21, G28

This paper analyzes the effect of the removal of government guarantees on bank risk taking. We exploit the removal of guarantees for German Landesbanken which results in lower credit ratings, higher funding costs, and a loss in franchise value. This removal was announced in 2001, but Landesbanken were allowed to issue guaranteed bonds until 2005. We find that Landesbanken lend to riskier borrowers after 2001. This effect is most pronounced for Landesbanken with the highest expected decrease in franchise value. Landesbanken also significantly increased their off-balance sheet exposure to the global ABCP market. Our results provide implications for the debate on how to remove guarantees.

Flight to where? Evidence from bank investments during the financial crisis

AFA 2013 San Diego Meetings Paper
2012 EFA Best Conference Paper
Thomas Hildebrand, Jörg Rocholl, Alexander Schulz (2012)
Subject(s): Finance, accounting and corporate governance
Keyword(s): Bank investments, financial crisis, liquidity, home bias
JEL Code(s): G11, G21

This paper analyzes how banks react to the financial crisis and a deteriorating solvency and liquidity condition in their investment decisions and the composition of their financial assets. We use a novel dataset, which comprises all security investments by all German banks on a security-by-security basis between 2006 and 2011, and analyze whether and how banks use sales and purchases of these securities as the most direct and immediate way to change their overall asset structure. We find that banks substantially change their investment strategies with the beginning of the financial crisis. In particular, they shift their investments towards securities that are eligible as collateral in central bank credit operations and towards domestic securities. These patterns hold in particular for less healthy, lowly rated and large banks. Furthermore, banks with substantial exposure to troubled assets as for example Greek government bonds are particularly active in this perspective. Our results highlight the substantial changes in bank portfolios following the financial crisis, which constitute a major part of their assets, and have important implications for the current regulatory as well as policy debate on banks’ investment decisions.

Rules versus discretion in bank lending decisions

Manju Puri, Jörg Rocholl, Sascha Steffen (2011)
Subject(s): Finance, accounting and corporate governance
Keyword(s): Bank lending, discretion, soft information, default rates

This paper analyzes the importance of discretion in bank lending decisions. We use a unique dataset of more than 1 million loan applications to customers of German savings banks and can observe accept and reject decisions as well as loan performance. We document that discretion is widespread and economically significant, in particular for customers with an existing relationship with their bank and medium credit quality. This discretion is based on soft information mainly for customers with no credit history (e.g. younger customers) and on hard information mainly for customers with a given credit history (e.g. with significant use of their credit lines). Finally, we find no evidence that loans approved based on the loan officer’s discretion perform any differently than other loans. These results help us in better understanding the loan making process and thus to shed light on an important, open question of interest to academicians, banks, consumers and regulators.
