Öz

Bu çalışma, küresel ve ulusal makroekonomik belirsizliklerin Borsa İstanbul’da işlem gören dokuz farklı sektör endeksi üzerindeki etkilerini 2001-2022 dönemi verileriyle incelemektedir. Çalışmada; Küresel Ekonomik Politika Belirsizliği, ABD Ekonomik Politika Belirsizliği, Dünya Belirsizlik Endeksi ve Türkiye Jeopolitik Risk Endeksinin etkileri, temel makroekonomik kontrol değişkenleri altında zaman serisi regresyonu ve Wavelet Uyum Analizi ile test edilmiştir. Elde edilen bulgular, küresel politika belirsizliğinin sektör getirileri üzerinde baskılayıcı bir etkiye sahip ve öncü bir gösterge niteliğinde olduğunu; buna karşın yerel jeopolitik risklerin risk primi kanalıyla getirileri nominal düzeyde artırabildiğine işaret etmektedir. Sektörel bazda yapılan analizler, finansal varlık ağırlıklı bankacılık ve yüksek kaldıraçlı elektrik sektörlerinin belirsizlik şoklarına karşı daha kırılgan bir yapı sergilediğini; buna karşın sınai sektörünün reel varlık ve stok yapısı sayesinde görece daha dirençli kalabildiğini göstermektedir. Elde edilen sonuçlar, yatırımcıların portföy çeşitlendirmesi yaparken ve politika yapıcıların sektörel düzenlemeleri tasarlarken, sektörlerin bilanço niteliklerini ve varlık-kaynak kompozisyonlarını dikkate almalarının önemini ortaya koymaktadır.
