Özet

Bu çalışma, DeFi (merkeziyetsiz finans) piyasaları, emtia piyasaları ve korku endeksi (VIX) ile kırılgan beşli ülkelerin (Brezilya, Hindistan, Endonezya, Türkiye ve Güney Afrika) borsa fiyatları arasındaki dinamik ilişkileri zaman ve frekans boyutunda incelemeyi amaçlamaktadır. Çalışma kapsamında 2019-2024 dönemi arasındaki DeFi piyasalarını temsilen en uzun örneklem geçmişine sahip olan Link, Maker ve Basic Attention Token varlıkları, emtia piyasalarını temsil eden petrol ve altın fiyatları ile VIX korku endeksi kullanılmıştır. Elde edilen sonuçlar, DeFi, altın ve petrol piyasaları ile kırılgan beşli ülkelerin hisse senedi getirileri arasında farklı zaman dilimlerinde pozitif bir korelasyon olduğunu göstermektedir. Öte yandan, VIX endeksi ile kırılgan beşli ülkelerin borsa endeksleri arasında kısa, orta ve uzun vadede negatif yönlü bir ilişki tespit edilmiştir. Ancak, değişkenler arasındaki öncülük ilişkisine dair belirgin bir bulgu elde edilememiştir. Bu bulgular, DeFi piyasaları, emtia fiyatları ve VIX korku endeksinin kırılgan beşli ülkelerinin borsa piyasaları üzerindeki etkilerini daha iyi anlamaya katkı sağlamaktadır. Özellikle, kırılgan beşli ülkelerin küresel piyasa şoklarına karşı duyarlılığının yüksek olması nedeniyle, risk yönetimi stratejilerinin güçlendirilmesi gerektiği sonucuna varılmıştır.

Abstract

This study aims to examine the dynamic relationship between DeFi (decentralized finance) markets, commodity markets, fear index (VIX), and stock prices of fragile five countries (Brazil, India, Indonesia, Turkey, and South Africa) in time and frequency dimensions. Within the scope of the study, Link, Maker, and Basic Attention Token assets with the longest sample history representing DeFi markets between 2019-2024, oil and gold prices representing commodity markets, and the VIX fear index were used. The results obtained show that there is a positive correlation between DeFi, gold and oil markets, and stock returns of fragile five countries in different time periods. On the other hand, a negative relationship was found between the VIX index and stock indices of fragile five countries in the short, medium and long term. However, no clear finding was obtained regarding the leading relationship between the variables. These findings contribute to a better understanding of the effects of DeFi markets, commodity prices and VIX fear index on stock markets of fragile five countries. In particular, it was concluded that risk management strategies should be strengthened due to the hogh sensitivity of the fragile five countries to global market shocks.
