COVID-19 ve Döviz Kurunun Zeytinyağı Piyasaları ve Gıda Güvenliği Üzerindeki Etkileri

Year 2025, Volume: 27 Issue: 1, 123 - 137, 30.06.2025

Abstract

Bu araştırmanın amacı, COVID-19 ve dışsal dolar döviz kuru değişkenleri kullanılarak Türkiye’de sızma zeytinyağı ile ham zeytinyağı piyasalarındaki uzun vadeli dalgalanma yayılımlarının belirlenmesi ve bu geçişkenliklerin asimetrikliğini araştırmaktır. Bu araştırma için gerekli analizler, Mayıs 2005 ile Haziran 2024 arasındaki döneme ait günlük veriler kullanılarak VECM (1)-Asimetrik BEKK-GARCH (1, 1) modeli ile gerçekleştirilmiştir. Ampirik bulgulara göre, hem kısa vadeli şoklar hem de uzun dönemli belirsizlikler sızma ve ham zeytinyağı getiri serilerinin koşullu varyanslarını önemli düzeyde artırmıştır. Sızma zeytinyağı piyasasındaki uzun vadeli belirsizliğin artışı, ham zeytinyağı piyasasındaki uzun dönemli volatiliteyi azaltıcı bir etki yapmaktadır. Sızma ve ham zeytinyağı getiri serilerinin şartlı varyanslarının uzun vadede COVID-19’dan kaynaklanan dalgalanmalardan negatif yönde etkilendikleri görülmüştür. Uzun vadede COVID-19, piyasalar arası ikili etkileşimlerdeki belirsizlikleri artırmış ve tüketicilerin ham ve sızma zeytinyağına erişimini olumsuz etkileyerek gıda güvenliğini ciddi şekilde tehdit etmiştir. Döviz kurundaki dalgalanmaların sızma ve ham zeytinyağı piyasalarındaki oynaklıkları azalttığı gözlenmiştir. Türkiye'deki politika yapıcılara, pandemi veya benzeri krizler nedeniyle küresel gıda tedarik zincirlerinin bozulma olasılığı dikkate alınarak gıda ürünlerine yönelik spesifik politikaların uygulanması önerilmektedir.

Ethical Statement

Sorumlu yazar olarak tüm yazarlar adına, yayınlanmak üzere derginize gönderdiğimiz “Impacts of COVID-19 and Exchange Rates on Olive Oil Markets and Food Security” başlıklı çalışmada kullanılan sızma ve ham zeytinyağı fiyatlarına ilişkin veriler, Aydın ve Edremit Emtia Borsası Piyasaları Veri Tabanı'nın günlük kayıtlarından elde edilmiştir. Reel dolar döviz kuru serileri ise Türkiye Cumhuriyeti Merkez Bankası'nın (TCMB) Elektronik Veri Dağıtım Sistemi'nden (EVDS) elde edilmiştir. Bu çalışmada; Etik Kurul Onay Belgesi gerektiren anket, mülakat, odak grup çalışması, gözlem, deney, görüşme gibi herhangi bir teknikle elde edilebilen veriler kullanılmamıştır.

Impacts of COVID-19 and Exchange Rates on Olive Oil Markets and Food Security

Year 2025, Volume: 27 Issue: 1, 123 - 137, 30.06.2025

Abstract

The objective of this research is to identify the long-term fluctuation spillovers in the Turkish extra-virgin olive oil and crude olive oil markets using COVID-19 and the external dollar exchange rate variables and to examine the asymmetry of these spillovers. The analyses required for this research were performed with the VECM (1)-Asymmetric BEKK-GARCH (1, 1) model, using daily data for the period from May 2005 to June 2024. According to the empirical findings, both brief shocks and long-term uncertainties have significantly increased the conditional variances of the extra-virgin and crude olive oil return series. An increase in long-term uncertainty in the extra-virgin olive oil market has a dampening effect on the long-term volatility in the crude olive oil market. It was observed that the conditional variances of the extra-virgin and crude olive oil return series were negatively affected by fluctuations stemming from COVID-19 in the long run. In the long term, COVID-19 increased uncertainties in bilateral interactions between markets, seriously threatening food security by negatively impacting consumer access to crude and extra-virgin olive oil. It was noted that fluctuations in the exchange rate reduced the volatilities in the extra virgin and crude olive oil markets. It is recommended that policymakers in Turkey implement specific policies for food commodities, considering the possibility of disruptions in global food supply chains due to pandemics or similar crises.
