In most economies banking sector plays the major role in the financial system. Therefore, it is of great importance to analyse and understand the mechanism of transmission of monetary policy and its impact on the banking sector. One of possible repercussions of changing the level of official interest rates is an ability to influence the size of bank lending, by means of the bank lending channel. The key aspect our research is a throughout understanding of functioning of the bank lending channel, with the main goal of this study being an examination of efficiency of monetary policy transmission through bank lending channel depending on the size of banks in the sector. This paper examines the abovementioned relation using annual data from 1995-2015 by 1709 commercial and cooperative banks from 27 EU countries and analyzing them in various econometric models. The results indicate that there is a positive impact of the bank's size on loan growth (defined as the bank size increases, the impact of changes in interest rates in the bank’s lending policy is getting smaller), however, interaction between the variables size and the interest rate, was proved to be insignificant (in the group of all analysed banks, as well as in commercial and cooperative banks separately).

Impact of credit rating agencies on European Banking stock prices: Is the recognition of credit rating agency important?

 

  • Patrycja Chodnicka-Jaworska

 

The basic goal of the article was to analyse the reaction of rates of return of banks’ shares to the changes of their credit ratings. There first hypothesis is as follows: Rating events convey new information and lead to statistically significant abnormal reactions. The second one is: The rate of return reaction is stronger on the decrease than increase of banks’ credit ratings. The last hypothesis that has been taken into considerations is: The changes of credit ratings proposed by smaller CRAs influence is ineffective on the rate of returns of banks’ shares. For verification of these hypothesis daily rates of return and differences between the logarithmized rates of returns are used. As dependent variables long term issuer credit ratings proposed European banks by the recognizable and smaller CRAs form 1980 to 2015 period of time are used. The analysis has been prepared in the subsamples according to: the type of credit rating, the recognizable credit rating agency and political division. The information about the upgrade and downgrade of credit ratings published by the smaller CRAs has insignificant influence on the abnormal returns. Banks in the developing economies reaction is stronger on the positive changes, but rates of return of banks’ shares in the developed countries are more sensitive to the downgrade of credit ratings. The moment of the reaction in particular countries is differentiated.

Keywords: credit rating agency, credit rating, stock price, rates of return.

  • Patrycja Chodnicka-Jaworska
  • Piotr Jaworski

 

The aim of the paper is to analyse the impact of the changes in credit ratings on the stock market, comparing the Chinese and the American Big Three agencies. A literature review has been made and as a result the following three hypotheses have been put. The first one seems as follows: Changes in credit ratings have influence in the case of both upgrades and downgrades of stock prices. The second one is: A stronger reaction of the stock market is observed as an effect of credit rating changes presented by the Chinese and not the American agencies. The third one seems as follows: The impact of credit rating changes is stronger for non-financial institutions and larger companies. Daily observation of the rates of returns on the stock prices and long-term issuer credit ratings proposed by the Chinese and the biggest three rating agencies (S&P’s, Moody’s and Fitch) have been taken for the analysis. Data has been collected from the Thomson Reuters Database from the period between 1990 and 2016. Event study methods have been used to verify the mentioned hypotheses.
