Loan Securitisation during the Transition to a Low-carbon Economy
Isabella Müller, Huyen Nguyen, Trang Nguyen
VoxEU CEPR,
May
2023
Abstract
Banks play a crucial role in the transition to a low-carbon economy, but they also expose themselves to climate transition risk. This column shows that banks use corporate loan securitisation to shift climate transition risk to less-regulated shadow banking entities. This behaviour affects carbon premia in loan contracts. When banks can use securitisation to manage transition risk, their climate policies that target only activities reflected in their books may not be as effective as bank regulators hope for.

Short-Selling Threats and Bank Risk-Taking: Evidence from the Financial Crisis
Dien Giau Bui, Iftekhar Hasan, Chih-Yung Lin, Hong Thoa Nguyen
Journal of Banking and Finance,
May
2023
Abstract
The focus of this paper is whether the Securities and Exchange Commission's Regulation SHO strengthens or weakens the effect of short-selling threats on banks’ risk-taking. The evidence shows that pilot banks with looser constraints on short-selling increased their risk-taking during the financial crisis of 2007–2009. The reason is that short-selling threats improved the information environment and mitigated the agency problems of banks during the pilot program that led to greater risk-taking by pilot banks. Additionally, this effect is mainly driven by pilot banks with poor corporate governance, or high information asymmetry. Overall, our paper provides novel evidence that the disciplinary role of short-sellers had a positive effect on bank risk-taking during the financial crisis.

Monetary Policy in an Oil-dependent Economy in the Presence of Multiple Shocks
Andrej Drygalla
Review of World Economics,
February
2023
Abstract
Russian monetary policy has been challenged by large and continuous private capital outflows and a sharp drop in oil prices during 2014. Both contributed to significant depreciation pressures on the ruble and led the central bank to give up its exchange rate management strategy. Against this background, this work estimates a small open economy model for Russia, featuring an oil price sector and extended by a specification of the foreign exchange market to correctly account for systematic central bank interventions. We find that shocks to the oil price and private capital flows substantially affect domestic variables such as inflation and output. Simulations for the estimated actual strategy and alternative regimes suggest that the vulnerability of the Russian economy to external shocks can substantially be lowered by adopting some form of inflation targeting. Strategies to target the nominal exchange rate or the ruble price of oil prove to be inferior.

Study on Europe's top bankers: Risky business despite bonus cap
Ten years ago, the EU Parliament decided to cap the flexible remuneration of bank managers. But the cap on bonuses misses its target: Managers of systemically important European banks take high risks without changes, shows a study by the Halle Institute for Economic Research (IWH).

What Explains International Interest Rate Co-Movement?
Annika Camehl, Gregor von Schweinitz
IWH Discussion Papers,
No. 3,
2023
Abstract
We show that global supply and demand shocks are important drivers of interest rate co-movement across seven advanced economies. Beyond that, local structural shocks transmit internationally via aggregate demand channels, and central banks react predominantly to domestic macroeconomic developments: unexpected monetary policy tightening decreases most foreign interest rates, while expansionary local supply and demand shocks increase them. To disentangle determinants of international interest rate co-movement, we use a Bayesian structural panel vector autoregressive model accounting for latent global supply and demand shocks. We identify country-specific structural shocks via informative prior distributions based on a standard theoretical multi-country open economy model.

The Disciplining Effect of Supervisory Scrutiny in the EU-wide Stress Test
Christoffer Kok, Carola Müller, Steven Ongena, Cosimo Pancaro
Journal of Financial Intermediation,
January
2023
Abstract
Relying on confidential supervisory data related to the 2016 EU-wide stress test, this paper presents novel empirical evidence that supervisory scrutiny associated to stress testing has a disciplining effect on bank risk. We find that banks that participated in the 2016 EU-wide stress test subsequently reduced their credit risk relative to banks that were not part of this exercise. Relying on new metrics for supervisory scrutiny that measure the quantity, potential impact, and duration of interactions between banks and supervisors during the stress test, we find that the disciplining effect is stronger for banks subject to more intrusive supervisory scrutiny during the exercise. We also find that a strong risk management culture is a prerequisite for the supervisory scrutiny to be effective. Finally, we show that a similar disciplining effect is not exerted neither by higher capital charges nor by more transparency and related market discipline induced by the stress test.

Carbon Transition Risk and Corporate Loan Securitization
Isabella Müller, Huyen Nguyen, Trang Nguyen
IWH Discussion Papers,
No. 22,
2022
Abstract
We examine how banks manage carbon transition risk by selling loans given to polluting borrowers to less regulated shadow banks in securitization markets. Exploiting the election of Donald Trump as an exogenous shock that reduces carbon risk, we find that banks’ securitization decisions are sensitive to borrowers’ carbon footprints. Banks are more likely to securitize brown loans when carbon risk is high but swiftly change to keep these loans on their balance sheets when carbon risk is reduced after Trump’s election. Importantly, securitization enables banks to offer lower interest rates to polluting borrowers but does not affect the supply of green loans. Our findings are more pronounced among domestic banks and banks that do not display green lending preferences. We discuss how securitization can weaken the effectiveness of bank climate policies through reducing banks’ incentives to price carbon risk.

Capital Markets Union: Database of Directives and Regulations
Moritz Emlein, Eleonora Sfrappini, Lena Tonzer, Cristina Zgherea
IWH Technical Reports,
No. 2,
2022
Abstract
In 2015, the European Commission adopted the Capital Markets Union (CMU) action plan. The plan aims to deepen financial integration and harmonize international standards for investments within the European Union (EU) and it outlines several actions to be implemented in order to address twelve key priority areas. We assemble a database of the legislative acts that implement the CMU. The dataset includes a list of directives and regulations at the EU level with information on publication, entry into force, and transposition dates as well as brief descriptions. This information might be useful in empirical analyses assessing the effectiveness of components of the CMU.
