The Effects of Sovereign Risk: A High Frequency Identification Based on News Ticker Data

IWH Discussion Papers,
No. 8,
2022
Abstract
This paper uses novel news ticker data to evaluate the effect of sovereign risk on economic and financial outcomes. The use of intraday news enables me to derive policy events and respective timestamps that potentially alter investors’ beliefs about a sovereign’s willingness to service its debt and thereby sovereign risk. Following the high frequency identification literature, in the tradition of Kuttner (2001) and Guerkaynak et al. (2005), associated variation in sovereign risk is then obtained by capturing bond price movements within narrowly defined time windows around the event time. I conduct the outlined identification for Italy since its large bond market and its frequent coverage in the news render it a suitable candidate country. Using the identified shocks in an instrumental variable local projection setting yields a strong instrument and robust results in line with theoretical predictions. I document a dampening effect of sovereign risk on output. Also, borrowing costs for the private sector increase and inflation rises in response to higher sovereign risk.

Quid Pro Quo? Political Ties and Sovereign Borrowing
Gene Ambrocio, Iftekhar Hasan
Journal of International Economics,
November
2021
Abstract
Do stronger political ties with a global superpower improve sovereign borrowing conditions? We use data on voting at the United Nations General Assembly along with foreign aid flows to construct an index of political ties and find evidence that suggests stronger political ties with the US is associated with both better sovereign credit ratings and lower yields on sovereign bonds especially among lower income countries. We use official heads-of-state visits to the White House and coalition forces troop contributions as additional measures of the strength of political ties to further reinforce our findings.

The Dilemma of International Diversification: Evidence from the European Sovereign Debt Crisis
Bill Francis, Iftekhar Hasan, Gergana L. Kostova, Sami Ben Naceur
Asia-Pacific Journal of Financial Studies,
No. 2,
2020
Abstract
This paper tests how capital markets value the international diversification of banks in good and in bad economic times by investigating changes in domestic and foreign sovereign debt ratings before and during the European sovereign debt crisis. Tracing 320 European banks in 29 countries and 226 credit rating announcements for European sovereigns between 1 January 2001 and 15 August 2012, we show that the market values banks with access to foreign funds. Despite occasional adverse effects immediately following negative news regarding sovereign credit rating changes, international diversification was found to be beneficial to European banks, especially during periods of distress.

The Case for a European Rating Agency: Evidence from the Eurozone Sovereign Debt Crisis
Marc Altdörfer, Carlos A. De las Salas Vega, Andre Guettler, Gunter Löffler
Journal of International Financial Markets, Institutions and Money,
2019
Abstract
Politicians frequently voice that European bond issuers would benefit from the presence of a Europe-based rating agency. We take Fitch as a prototype for such an agency. With its ownership structure and a headquarter in London, Fitch is more European than Moody’s and S&P; during the Eurozone sovereign debt crisis, it also issued more favorable ratings. Fitch’s rating actions, however, were largely ignored by the bond market. Our results thus cast doubt on the benefits of a European credit rating agency.

Politics, Banks, and Sub-sovereign Debt: Unholy Trinity or Divine Coincidence?
Michael Koetter, Alexander Popov
Deutsche Bundesbank Discussion Paper,
No. 53,
2018
Abstract
We exploit election-driven turnover in State and local governments in Germany to study how banks adjust their securities portfolios in response to the loss of political connections. We find that local savings banks, which are owned by their host county and supervised by local politicians, increase significantly their holdings of home-State sovereign bonds when the local government and the State government are dominated by different political parties. Banks' holdings of other securities, like federal bonds, bonds issued by other States, or stocks, are not affected by election outcomes. We argue that banks use sub-sovereign bond purchases to gain access to politically distant government authorities.

On the Risk of a Sovereign Debt Crisis in Italy
Oliver Holtemöller, Tobias Knedlik, Axel Lindner
Intereconomics,
No. 6,
2018
Abstract
The intention for the Italian government to stimulate business activity via large increases in government spending is not in line with the stabilisation of the public debt ratio. Instead, if such policy were implemented, the risk of a sovereign debt crisis would be high. In this article, we analyse the capacity of the Italian economy to shoulder sovereign debt under different scenarios. We conclude that focusing on growth enhancing structural reforms, would allow for moderate increases in public expenditure.

Zum Risiko einer Staatsschuldenkrise in Italien
Oliver Holtemöller, Tobias Knedlik, Axel Lindner
Abstract
Die wirtschaftliche Entwicklung Italiens war in den vergangenen Jahren durch eine ausgesprochen schwache Produktivitätsentwicklung gekennzeichnet. Das Bruttoinlandsprodukt je Einwohner beträgt nur 92% des Niveaus im Jahr 2007, während es im Euroraum insgesamt (inklusive Italien) bei 103% des Vorkrisenniveaus von 2007 liegt. Die Staatsschuldenquote ist im Zeitraum von 2007 bis 2017 von 100% in Relation zum Bruttoinlandsprodukt um 30 Prozentpunkte auf 130% gestiegen. Es bestehen daher Zweifel, ob die Wirtschaftskraft Italiens ausreichend ist, um die weiter steigenden Staatsschulden künftig bedienen zu können. Diese Zweifel kommen zum Beispiel in der gegenwärtig (August 2018) um gut 3 Prozentpunkte höheren Umlaufsrendite 10-jähriger italienischer Staatsanleihen im Vergleich zu deutschen Staatsanleihen zum Ausdruck.
Die Regierung Italiens will der Wirtschaft durch expansive Finanzpolitik wieder auf die Beine helfen. Im vorliegenden Beitrag wird die Tragfähigkeit der italienischen Staatsverschuldung für verschiedene Szenarien analysiert. Dabei gibt es je nach den getroffenen Annahmen zu wichtigen Wirkungszusammenhängen eine ganze Bandbreite von möglichen Entwicklungen, die aber allesamt eine deutlich expansive Finanzpolitik für Italien nicht ratsam erscheinen lassen, weil sie insgesamt nicht förderlich für die Stabilisierung der Staatsverschuldung wäre. Vielmehr sollten produktivitätssteigernde Strukturreformen umgesetzt werden, die dann auch moderat höhere Staatsausgaben erlauben würden.

Comments on “Consultation BCBS discussion paper on the regulatory treatment of sovereign exposures”
Michael Koetter, Lena Tonzer
Einzelveröffentlichungen,
2018
Abstract
The BCBS discussion paper on the regulatory treatment of sovereign exposures addresses a so far hardly touched topic as concerns capital regulation. While the regulatory framework has been changed substantially over recent years including the establishment of the European Banking Union, risk weights on sovereign exposures have remained mostly unchanged and sovereign exposures of banks benefit from a favourable capital treatment. This applies despite the fact that the recent European sovereign debt crisis has revealed the potential of a doom loop between bank and sovereign risk and demonstrated that sovereign exposures are by no means “risk-free”. The paper is thus an important proposal how to change the risk evaluation of banks’ sovereign exposures.

Sovereign Stress, Banking Stress, and the Monetary Transmission Mechanism in the Euro Area
Oliver Holtemöller, Jan-Christopher Scherer
IWH Discussion Papers,
No. 3,
2018
Abstract
In this paper, we investigate to what extent sovereign stress and banking stress have contributed to the increase in the level and in the heterogeneity of nonfinancial firms’ refinancing costs in the Euro area during the European debt crisis and how they did affect the monetary transmission mechanism. We identify the increasing effect of government bond yield spreads (sovereign stress) and the share of non-performing loans (banking stress) on firms’ financing costs using an instrumental-variable approach. Moreover, we estimate both sources of stress to have significantly impaired the monetary transmission mechanism during the European debt crisis.
