Analysis of Swap Agreements Using the Event Study Method: The Case of Türkiye and China

Öz

This study was conducted to examine the effects of the bilateral currency swap agreement between the Central Banks of Türkiye and China on June 15, 2021, on 11 sectors traded in BIST100. In the study, event study method was used to evaluate the effects of sudden events occurring in financial markets on investor behavior and short-term effects were analyzed through abnormal returns. In the research, the closing values of the stock market indices were examined and abnormal returns (AR), average abnormal returns (AAR), cumulative abnormal returns (CAR) and cumulative average abnormal returns (CAAR) were calculated based on these values. In the study, the period t + 10, t – 10, before and after the event day, was taken as the event window. The time period examined covers a total of 21 days before and after the agreement. The findings show that cumulative abnormal returns in the Technology, Information, Electricity, Mining, Metal Goods-Machinery, and Stone-Earth sectors are positive, indicating a positive investor reaction to the agreement; while cumulative abnormal returns observed in the Communication, Chemical-Petroleum-Plastics, Metal-Primary, and Trade sectors are negative, indicating a negative investor reaction to the agreement.It was concluded that the event had a generally negative impact on the 11 sectors traded in the BIST100, but there were also certain types of positive or fluctuating reactions. These findings support the hypothesis that markets are not semi-strong form efficient and reveal that currency swap agreements have significant effects on 11 sectors traded in BIST 100.
