Abstract

This study aims to identify and analyze the effects of Turkish Central Bank's interventions over currency rate volatility. US Dolar and Euro Returns of Turkish Lira between 04.01.1999 and 24.09.2008 are modelled in the study. Econometric methods used are ARFIMA-GARCH and ARFIMA-FIGARCH models. Findings obtained from model verify the presence of long memory properties, and increasing effects of Central Bank's interventions over currency volatility. According to model's findings, currency shocks have no permanent characteristic and market dynamics will return stability back to markets; therefore, Central Bank should avoid intervening currency markets.

Özet

Bu çalışmanın amacı Türkiye’de merkez bankası müdahalelerinin döviz kuru oynaklığı üzerindeki etkilerini belirlemek ve analiz etmektir. Çalışmada, Euro ve Dolar kurlarının getirileri 4.1.1999 – 24.9.2008 döneminin bütünü ve alt dönemleri itibariyle modellenmiştir. Ekonometrik analiz yöntemi olarak ARFIMA-GARCH ve ARFIMA-FIGARCH Modelleri kullanılmıştır. Elde edilen bulgular, hem uzun hafıza özelliklerinin varlığını, hem de merkez bankası müdahalelerinin kurlarda gözlenen oynaklığı arttırdığını ortaya koymaktadır. Bu bulgular ışığında, merkez bankasının döviz piyasalarına müdahale etmekten kaçınması gerektiği, olası döviz şoklarının kalıcı olmayacağı ve piyasanın dinamikleriyle kısa sürede istikrar sağlanacağı sonucuna varılmıştır.
