U.S. 10-YEAR TREASURY YIELDS AND REAL PRIVATE SECTOR CREDIT IN TÜRKİYE: TIME-VARYING ASYMMETRIC CAUSALITY
Abstract
The purpose of this study is to examine whether the direction of the causal relationship between U.S. 10-year Treasury yields and real loans extended by commercial banks in Turkey to the private sector varies depending on the type of shock and over time. The analysis was conducted using monthly data from January 2003 to March 2026, employing the Hatemi-J (2012) static asymmetric causality test and the Hatemi-J (2022) time-varying asymmetric causality method. The static results indicate that there is no causality among positive shocks, whereas there is bidirectional causality among negative shocks. The time-varying results reveal that causality from U.S. interest rates to real loans in Turkey became evident particularly during the 2008–2012 period for negative shocks, and in sub-periods following November 2021 for positive shocks. While no causality was detected from real loans in Turkey to U.S. interest rates during positive shocks, a relationship was found during negative shocks only in specific sub-periods. The findings indicate that the forecasting relationship between the two variables is neither constant nor symmetric across the sample but varies depending on the direction of the shock and the sub-period. This result underscores the importance of evaluating movements in U.S. long-term interest rates in conjunction with global and domestic financial conditions from the perspective of financial stability.
