Abstract

Dünyanın herhangi bir yerinde yaşanan finansal ve siyasi krizler, sosyal ve politik olaylar, salgın hastalıklar ve savaşlar, ülkelerdeki tüm sektörleri etkilemektedir. Global ekonomiler, Covid 19 salgınının oluşturduğu yaraları sarmaya çalışırken, Rusya-Ukrayna savaşıyla birlikte yeni bir belirsizlik ortamının içerisine girmiştir. Rusya’nın Ukrayna’yı 24 Şubat 2022 tarihinde işgaliyle başlayan savaşın, dünya ekonomisi ve finansal piyasalar üzerinde pek çok etkisi bulunmaktadır. Bu savaşla birlikte tüm dünyada petrol, enerji, gıda ve emtia piyasaları olumsuz etkilenmiştir. Dolayısıyla Covid 19 salgını sonrası küresel olarak ekonomilerde beklenen toparlanma gecikmiştir. Savaşla beraber tüm dünyada ekonomilerinde mevcut belirsizlik ortamı daha da derinleşmiştir. Bu belirsizlik ortamından, savaşa taraf olanlarla beraber taraf olmayanlar da etkilenmektedir. Rusya-Ukrayna savaşı, tüm ülkelere ekonomik bir maliyet yüklemiştir. Ayrıca dünyadaki tüm finansal piyasalarda savaşın devam etmesi nedeniyle belirsizlikle beraber risk ortamıda oluşmuştur. Bu çerçevede, bu çalışma ile Rusya ve Ukrayna arasında devam eden savaşa, BIST 100 endeksinin verdiği tepki ölçülmeye çalışılmıştır. Bu çalışmada Rusya’nın Ukrayna'yı işgal etmeye başladığı 24 Şubat 2022 tarihinin öncesi ve sonrası dönemleri kapsayan, 05.08.2021-05.09.2022 tarihleri arasında, BIST 100 Endeksinin değişimleri tespit edilmeye çalışılmıştır. Çalışmada investing.com adresinden elde edilen verilerin analizi, R programında 4.2.0 "Vigorous Calisthenics" versiyonunda yapılmıştır. Çalışma sonuçlarına göre yapısal kırılma analizinde dikkate alınan dönem içerisinde savaşın BIST 100 üzerinde farklı etkilerinin olduğu ortaya konulmuştur.
