Kırılgan Beşli Ekonomilerinin Döviz Kuru Hareketleri: Dolar Endeksini Takip Ediyorlar mı?
(2019) Fatma Dilvin TAŞKIN; Efe C. Cagli; Taşkın, Fatma Dilvin; Cagli, Efe C.
Bu çalışmada dolar endeksi ile ‘Kırılgan Beşli’ ülkeleri döviz kurları arasındaki uzun dönemli ilişki incelenmektedir. Türkiye Endonezya Brezilya Güney Afrika ve Hindistan’ın döviz kurları ile birlikte ana ticaret ortakları ve başlıca para birimleri ağırlıklı dolar endeksleri analiz edilmiştir. Ocak 2002 – Haziran 2018 dönemini kapsayan haftalık verilere doğrusal olmayan eşbütünleşme sistemi ve Granger nedensellik testleri uygulanmıştır. Sonuçlar döviz kurlarının ana ticaret ortakları ağırlıklı dolar endeksiyle uzun vadeli ilişkiye sahip olmadığını göstermektedir. Bununla birlikte dolar endeksinin kısa vadede Kırılgan Beşli döviz kurları üzerinde anlamlı etkisinin olduğu görülmektedir.

This study explores links between uncertainty metrics and fossil and green energy sectors applying an innovative quantile-on-quantile connectedness method to analyze spillovers across quantiles from August 2004 to December 2023. Our sample comprises the clean and fossil energy market indices and key uncertainty measures including climate economic geopolitical and infectious diseases uncertainty indices. All total connectedness indices were found to peak at extremely reversely related quantiles except for climate policy uncertainty. The strongest connectedness is between high economic policy uncertainty and low clean energy returns. The economic policy uncertainty index was dynamically reversely related to energy markets in all quantiles. However after 2016 the connectedness between climate policy uncertainty and energy market indices converted to positive possibly due to the impact of the Paris Agreement. Compared to climate-related uncertainty geopolitical and economic uncertainties have a notably more substantial influence on energy markets particularly in the green energy sector. Other findings reveal that energy market performance significantly influences climate policy uncertainty and that infectious disease uncertainty is transmitted across various quantiles. Given the findings we propose policy implications for investors and policymakers emphasizing the critical need for considering different quantiles in measuring the dynamic connectedness between various uncertainties and energy markets. © 2025 Elsevier B.V.
