Much Ado About Nothing: Sovereign Ratings and Government Bond Yields in the OECD
Makram El-Shagi
IWH Discussion Papers,
No. 22,
2016
Abstract
In this paper, we propose a new method to assess the impact of sovereign ratings on sovereign bond yields. We estimate the impulse response of the interest rate, following a change in the rating. Since ratings are ordinal and moreover extremely persistent, it proves difficult to estimate those impulse response functions using a VAR modeling ratings, yields and other macroeconomic indicators. However, given the highly stochastic nature of the precise timing of ratings, we can treat most rating adjustments as shocks. We thus no longer rely on a VAR for shock identification, making the estimation of the corresponding IRFs well suited for so called local projections – that is estimating impulse response functions through a series of separate direct forecasts over different horizons. Yet, the rare occurrence of ratings makes impulse response functions estimated through that procedure highly sensitive to individual observations, resulting in implausibly volatile impulse responses. We propose an augmentation to restrict jointly estimated local projections in a way that produces economically plausible impulse response functions.

The Joint Dynamics of Sovereign Ratings and Government Bond Yields
Makram El-Shagi, Gregor von Schweinitz
Abstract
Can a negative shock to sovereign ratings invoke a vicious cycle of increasing government bond yields and further downgrades, ultimately pushing a country toward default? The narratives of public and political discussions, as well as of some widely cited papers, suggest this possibility. In this paper, we will investigate the possible existence of such a vicious cycle. We find no evidence of a bad long-run equilibrium and cannot confirm a negative feedback loop leading into default as a transitory state for all but the very worst ratings.

UK’s “No” to EU will be costly for both sides
On Thursday 23rd, the British people have decided to leave the European Union (EU) Their vote not to remain in the European community was surprisingly clear. UK’s exit will have both political and economic consequences which are far-reaching for the country itself as well as the rest of Europe. “The reactions of the remaining member states are the crucial key now, especially France’s and Germany’s” says Reint E. Gropp, President of the Halle Institute for Economic Research (IWH) – Member of the Leibniz Association.

Financial market reaction to poll data suggests strong effects of a Brexit on exchange rates and the banking system both in the UK and in the EU
On 23 June 2016, there will be a referendum in the United Kingdom (UK) on the question of whether or not the country should remain in the European Union (EU). We use the polls as a measure of the likelihood of an exit to examine the likely effect of a Brexit on financial markets. “Whenever the probability in the polls of a Brexit moves above 50%, we observe a substantial depreciation of the UK pound with respect to most major currencies (including the euro), and strong decline in bank stock prices, suggesting that markets feel the financial sector (both in the UK and the EU) will be most severely affected by a Brexit”, IWH President Reint E. Gropp says. There is little effect on the euro/US Dollar exchange rate. “A huge concern is that overall market volatility both in the UK and the EU are on record highs since last Thursday, reflecting the higher uncertainty associated with Brexit and how exactly, if it happened, it would come about.” Within the UK, we see some evidence for a flight to safety into UK government bonds, but no effects for German bonds.

The German Economy Benefits from Strong Domestic Demand
In 2016, the moderate upswing of the German economy continues. Incomes grow due to the steady expansion in employment, and the fall in energy prices has propped up the purchasing power of private households. As a consequence, private consumption expands healthily; investment in housing is additionally stimulated by very low interest rates. Exports, however, expand only moderately, as the world economy is rather weak. All in all, the IWH forecasts the German GDP to expand by 1.8% in this year and by 1.6% in 2017.

Regional Banking Instability and FOMC Voting
Stefan Eichler, Tom Lähner, Felix Noth
Abstract
This study analyzes if regionally affiliated Federal Open Market Committee (FOMC) members take their districts’ regional banking sector instability into account when they vote. Considering the period from 1978 to 2010, we find that a deterioration in a district’s bank health increases the probability that this district’s representative in the FOMC votes to ease interest rates. According to member-specific characteristics, the effect of regional banking sector instability on FOMC voting behavior is most pronounced for Bank presidents (as opposed to governors) and FOMC members who have career backgrounds in the financial industry or who represent a district with a large banking sector.

Are Lacking Structural Reforms in the Financial Sector the Underlying Reason for the German Criticism of the ECB?
The major reason for the intense criticism of the European Central Bank’s (ECB’s) low-interest-rate policy may be the lack of structural reforms in the German banking system. The resulting persistent fragmentation increases the banking sector’s vulnerability to the low-interest-rate environment. Hence, parts of the banking sector, due to their strong ties to politicians, appear to have successfully influenced public opinion against the ECB.

Did TARP Distort Competition Among Sound Unsupported Banks?
Michael Koetter, Felix Noth
Economic Inquiry,
No. 2,
2016
Abstract
This study investigates if the Troubled Asset Relief Program (TARP) distorted price competition in U.S. banking. Political indicators reveal bailout expectations after 2009, manifested as beliefs about the predicted probability of receiving equity support relative to failing during the TARP disbursement period. In addition, the TARP affected the competitive conduct of unsupported banks after the program stopped in the fourth quarter of 2009. Loan rates were higher, and the risk premium required by depositors was lower for banks with higher bailout expectations. The interest margins of unsupported banks increased in the immediate aftermath of the TARP disbursement but not after 2010. No effects emerged for loan or deposit growth, which suggests that protected banks did not increase their market shares at the expense of less protected banks.

German Economy Stays Stable Despite Shaky Environment
The German economy had a good start into the year 2016, in spite of heightened risks for the world economy and political turmoil in Europe. Employment and incomes are expanding, as is internal de-mand, additionally supported by government spending related to the high number of newly arrived refugees. However, sliding sentiment indicates a temporary slow down of the economy during this spring. We assume that the present political tensions inside the European Union can be mitigated in the coming months and that confidence will rise again. All in all, gross domestic product (GDP) is forecast to rise by 1.5% in 2016.
