Does increasing foreign control in the banking sector have an impact on banks’ loan rates? : evidence from Turkey
(2017-05) Topaloğlu Bozkurt, Ayça
Foreign bank presence has been a growing trend in Turkey since 2000. Considering the fact that almost all of the entries are through acquisition of small-sized banks in the industry, we argue that this kind of a foreign entry to the Turkish banking sector may have little impact on the productivity or efficiency of the banking sector. We hypothesize that these banks have exercised very aggressive pricing strategies to benefit from growing loan demand for commercial loans, personal loans, vehicle and housing loans.Thus, in the thesis, we study the association between foreign bank presence and loan prices in the Turkish banking sector during the time period between December 2002 and September 2016. Different than previous studies, we use unique data, i.e., weighted average loan interest rates for commercial, personal, vehicle and housing loans of 19 deposit banks that was collected by Central Bank of the Republic of Turkey. Empirical results indicate that the foreign presence has a significant impact on the lending rates of Turkish banking sector regardless of the loan type. The impact is seen to be higher for large banks compared to small banks. We also find that the direction of the relation is varying among loan types. Particularly, there exist a negative relation between foreign presence and lending rates of commercial loans and a positive relation with vehicle and housing loans. Beyond a certain level of foreign presence, a competitive pricing in the credit market is found to reverse its direction suggesting regulatory agencies to monitor new foreign entries in Turkey.

Factors impacting bank net interest margin and the role of monetary policy: evidence from Turkey
(2017-01) Yılmaz, Muhammed Hasan
In this thesis, we study factors affecting net interest margin (NIM) of commercial banks in Turkey. Especially, our results highlight the relation between unconventional monetary policy shocks and bank margins. To this end, first, we conduct an identification analysis about which parameters of asymmetric interest corridor framework are important in explaining variations in NIM. Using industry-level data, we show that there exists a pass through from BIST interbank overnight repo/reverse repo market rate and weighted average cost of funding (WACF) to bank loan and deposit rates. As a result of reducedform Vector Autoregression (VAR) analysis we find the existence of a transmission mechanism from BIST rate and WACF to commercial loan rate, consumer loan rate and deposit rate. Same pass through to loan and deposit rates is also shown in individual bank level with the Panel Vector Autoregression (Panel VAR) analysis in the case of 16 commercial banks in Turkey during the period 2011Q1-2016Q1. After the identification analysis, we examine the relationship between NIM and policy rates through System Generalized Method of Moments techniques by controlling bank specific, industry related and macroeconomic factors. We find that a change in the monetary policy rate has significant and positive impact on NIM. Among bank-specific factors, equity ratio and operating expenses are found to be significantly affecting NIM during the sample period. Our empirical findings also stress the significance of lag values of NIM. Estimations conducted with standardized variables indicate that economic significance of lag values and bank specific variables are larger than that of policy.

Global financial crisis and risk perception
(2012) Polat, Tandoğan
The global financial crisis has caused remarkable deterioration in risk appetite and loss of confidence in financial markets. The countries, which succeeded a recovery in their macroeconomic structure, have been relatively less prone to the adverse effects of the crisis. The studies conducted on the impact of global crisis on economic indicators affecting the risk premiums of developing economies have been very limited. The focus of this thesis was on the revealing the change in market risk perceptions towards developing economies within the framework of a rolling base panel data analysis. The five-year Credit Default Swap (CDS) premium has been used as an indicator of country risk premium. According to the results of the panel analysis, in the pre-crisis period risk premiums are more heavily affected from the global developments as compared to domestic indicators, whereas investors have been giving more emphasis on domestic indicators in their risk perceptions with the burst of financial crisis.

Impact of liquidity on stock returns listed in Borsa Istanbul
(2015) Emrah, Nermin
This study investigates the impact of liquidity on returns of stocks traded at Borsa İstanbul for the 2002-2014 period. Turnover rate, which is defined as average volume of a firm divided by the number of shares outstanding of that firm, is used as a liquidity measure. Liquidity effect is examined following panel data analysis and robust estimators controlling the effect of well-known firm-specific characteristics. The results show that turnover rate has a significant and negative effect on stock returns. This result indicates that investors request compensation for holding illiquid assets. In other words, they request compensation for the assets with low turnover. The impact of turnover rate on stock returns is significant for the whole year; therefore, results are not driven by the January effect.
