In this paper
we analyze the stationarity of Turkish credit default swap (CDS) spreads
between 10:2000-08:2017 which is an important indicator for researchers and
practitioners. For our data, although the most widely used linear unit root
test namely augmented Dickey Fuller (ADF) test fails to reject the presence
unit root, non-linear tests of Kapatenios, Snell and Shin (KSS) and Sollis
claim stationarity with a smooth transition. Moreover, we detect asymmetry for
the encountered smooth transition. Thus we encourage researchers to apply KSS
and Sollis test along with ADF test in order to understand the driving
processes better which will strengthen the predictability and modeling issues
of CDS spreads.

Bu çalışmada
araştırmacı ve yatırımcılar için önemli gösterge niteliği taşıyan durağanlık
kavramı Türk Kredi Temerrüt Takası (KTT) primleri özelinde incelenmiştir.
Verimiz için her ne kadar en çok kullanılan doğrusal birim kök testi olan
Dickey Fuller (ADF) birim kökün varlığının reddedemezken, doğrusal olmayan Kapatenios,
Snell ve Shin (KSS) ve Sollis testleri yumuşak geçişli bir durağanlık
saptamışlardır. Ayrıca, bu yumuşak geçişin asimetrik bir yapıda olduğu
bulgularımız arasındadır. KTT primlerinin dinamiklerini anlama öngörülebilirlik
ve modellemeyi güçlendireceğinden araştırmacılara ADF testi beraberinde KSS ve
Sollis testlerini uygulamalarını da önetmekteyiz.
