Regulation of International Financial Markets and Banking

The research group "Regulation of International Financial Markets and Banking" analyzes international capital flows and the effects of regulatory changes on financial stability. Financial integration promotes efficient capital allocation and risk sharing but also eases the transmission of shocks across borders.

Banking regulation has accordingly evolved in recent years, yet the full impact of these reforms remains unclear. Hence, the group focuses on two areas:

First, it investigates the drivers of international capital flows and their effects on financial stability. Periods of high financial integration often precede crises with lasting real-economy consequences. The aim is to understand how to ensure stable and effective credit allocation.

Second, it examines how changes in regulation and supervision influence cross-border banking, especially within the context of European integration. This includes evaluating the balance between regulatory harmonization and unintended market distortions.

Two data projects support this research: the International Banking Library, a web-based platform for research exchange with a quarterly newsletter reaching more than 700 subscribers, and the Financial Markets Directives Database, which documents the implementation of key EU financial regulations with a special focus on the European Banking Union. Together, they promote evidence-based policymaking and enhance the group's global visibility.

Protect and Survive? Did Capital Controls Help Shield Emerging Markets from the Crisis?

Makram El-Shagi

in: Economics Bulletin, No. 1, 2012

Abstract

Using a new dataset on capital market regulation, we analyze whether capital controls helped protect emerging markets from the real economic consequences of the 2009 financial and economic crisis. The impact of the crisis is measured by the 2009 forecast error of a panel state space model, which analyzes the business cycle dynamics of 63 middle-income countries. We find that neither capital controls in general nor controls that were specifically targeted to derivatives (that played a crucial role during the crisis) helped shield economies. However, banking regulation that limits the exposure of banks to global risks has been highly successful.

The Impact of Fixed Exchange Rates on Fiscal Discipline

Makram El-Shagi

in: Scottish Journal of Political Economy, No. 5, 2011

Abstract

In this paper, it is shown that, contrary to standard arguments, fiscal discipline is not substantially enhanced by a fixed exchange rate regime. This study is based on data from 116 countries collected from 1975 to 2004 and uses various estimation techniques for dynamic panel data, in particular a GMM estimation in the tradition Arellano and Bover (1995) and Blundell and Bond (1998). Contrary to previous papers on this topic, the present paper takes into account that the consequences of a new exchange rate regime do not necessarily fully manifest immediately.

The Role of Rating Agencies in Financial Crises: Event Studies from the Asian Flu

Makram El-Shagi

in: Cambridge Journal of Economics, 2010

Abstract

Based on case studies from countries that have been hit hardest by the Asian financial crisis of 1997, the present paper shows that the accusation that sovereign ratings led to a severe acceleration of the crisis is unconvincing and that the empirical method often used to support accusations against rating agencies is inappropriate for the problem under analysis. Rather, it must be emphasised that ratings were downgraded in most countries very shortly before the end of the crisis. In some countries, the ratings were even further downgraded after the end of the crisis as countries started to recover. This is not in line with the thesis that the crisis was accelerated by rating agencies.

Capital Controls and International Interest Rate Differentials

Makram El-Shagi

in: Applied Economics, 2010

Abstract

Since the Asian crises it is often taken as granted that capital markets have significant functional deficits. Often these deficits are believed to be so very strong that the ability of free capital markets to guarantee a more or less correct international allocation of capital is denied. It is argued that speculation dominates capital markets so much that capital allocation is purely random. This is one of the major arguments backing the present trend to re-establish capital controls, which emerged after the capital market distortions observed during the Asian flu. In the present article it is shown that capital markets, while certainly prone to many distortions, are well capable of roughly guiding capital to the proper place. Though allocation is not model-like perfect, this steals the thunder from the idea, that closed or government-guided capital markets were able to perform better.

Banks’ foreign homes

Kirsten Schmidt Lena Tonzer

in: Deutsche Bundesbank Discussion Papers, No. 46, 2024

Abstract

<p>Our results reveal that higher lending spreads between foreign and home markets redirect real estate backed lending towards foreign markets offering a higher interest rate, which provides evidence for "search for yield" behavior. This re-allocation is found especially for banks with more expertise on the foreign market due to a higher local activity and holds for commercial and residential real estate backed loans. Furthermore, "search for yield" behavior and a resulting increase in foreign real estate backed lending is found when macroprudential regulation is missing or misaligned between a bank’s country of residence and the destination country. When turning to the question of whether the detected search for yield behavior results in more risk, we find that especially better capitalized banks report higher forbearance ratios as they might face less stigma effects compared to low capitalized banks.</p>

The Effect of Firm Subsidies on Credit Markets

Aleksandr Kazakov Michael Koetter Mirko Titze Lena Tonzer

in: IWH Discussion Papers, No. 24, 2022

Abstract

<p>We use granular project-level information for the largest regional economic development program in German history to study whether government subsidies to firms affect the quantity and quality of bank lending. We combine the universe of recipient firms under the Improvement of Regional Economic Structures program (GRW) with their local banks during 1998-2019. The modalities of GRW subsidies to firms are determined at the EU level. Therefore, we use it to identify bank outcomes. Banks with relationships to more subsidized firms exhibit higher lending volumes without any significant differences in bank stability. Subsidized firms, in turn, borrow more indicating that banks facilitate regional economic development policies.</p>

Climate Change-Related Regulatory Risks and Bank Lending

Isabella Müller Eleonora Sfrappini

in: ECB Working Paper, No. 2670, 2022

Abstract

We identify the effect of climate change-related regulatory risks on credit real-location. Our evidence suggests that effects depend borrower's region. Following an increase in salience of regulatory risks, banks reallocate credit to US firms that could be negatively impacted by regulatory interventions. Conversely, in Europe, banks lend more to firms that could benefit from environmental regulation. The effect is moderated by banks' own loan portfolio composition. Banks with a portfolio tilted towards firms that could be negatively a affected by environmental policies increasingly support these firms. Overall, our results indicate that financial implications of regulation associated with climate change appear to be the main drivers of banks' behavior.

Explaining Regional Disparities in Housing Prices Across German Districts

Lars Brausewetter Stephan L. Thomsen Johannes Trunzer

in: IWH Discussion Papers, No. 13, 2022

Abstract

Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: Growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: Increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.

Stress-ridden Finance and Growth Losses: Does Financial Development Break the Link?

Serafín Martínez-Jaramillo Ricardo Montañez-Enríquez Matias Ossandon Busch Manuel Ramos-Francia Anahí Rodríguez-Martínez José Manuel Sánchez-Martínez

in: IWH Discussion Papers, No. 3, 2022

Abstract

Does financial development shield countries from the pass-through of financial shocks to real outcomes? We evaluate this question by characterising the probability density of expected GDP growth conditional on financial stability indicators in a panel of 28 countries. Our robust results unveil a non-linear nexus between financial stability and expected GDP growth, depending on countries’ degree of financial development. While both domestic and global financial factors affect expected growth, the effect of global factors is moderated by financial development. This result highlights a previously unexplored channel trough which financial development can break the link between financial (in)stability and GDP growth.
