Bu çalışmada, banka sistemindeki döviz mevduatlarının artışına dayalı para ikamesi süreci analiz edilmekte ve Türkiye örneği üzerinden bu sorunun para politikalarının etkinliğine yansımaları değerlendirilmektedir. Çalışmada, Mizen’in (1999) teorik modeli temel alınarak geliştirilen eşanlı denklem sistemi, Türkiye için tahmin edilmiştir. 2002-2021 dönemini kapsayan aylık verilerle yapılan analizler, Mizen modelinin temel önermelerinin Türkiye’de de geçerli olabileceğini göstermektedir. Yüksek ve kronik enflasyon nedeniyle portföylerinde dövize daha çok yer veren yerleşikler, döviz varlıklarını banka sisteminde tutmayı tercih etmektedir. Ama bir kur şoku yaşanması halinde bu durum değişebilir. Döviz varlıkları banka sistemi içinde kaldıkça, ikame süreci merkez bankasınca yönetilebilir ve kur rejimi korunabilir. Bu süreçte rezervlerin teminat işlevi ve zorunlu karşılık oranlarının dengeleyici işlevi çok önemlidir. Rezervlerin erimesi ve/veya zorunlu karşılık politikasının yanlış yönetilmesi halinde, spekülatif kur atakları yaşanması durumunda, döviz mevduatlarının banka sistemi dışına kaçması ve para politikalarının etkinliğinin zayıflaması kaçınılmaz olacaktır. Böyle bir süreç, bir kur krizine hatta kısa bir gecikmeyle buna eşlik eden bir banka krizine evrilebilir.

In this study, the currency substitution process based on the increase in foreign currency deposits in the banking system is analyzed and the reflections of this problem on the effectiveness of monetary policies are evaluated through the example of Turkey. In the study, simultaneous equation system developed based on Mizen's (1999) theoretical model was estimated for Turkey. Analyzes with monthly data covering the period 2002-2021 show that the basic propositions of the Mizen model may also be valid in Turkey. Residents, who have more foreign currency in their portfolios due to high and chronic inflation, prefer to keep their foreign currency assets in the banking system. However, this may change in the event of a currency shock. As long as foreign exchange assets remain within the banking system, the substitution process can be managed by the central bank and the exchange rate regime can be maintained. In this process, the collateral function of reserves and the balancing function of required reserve ratios are very important. In case the reserves are melted and the reserve requirement policy is mismanaged, in case of speculative exchange rate attacks, it will be inevitable for foreign currency deposits to escape from the banking system and weaken the effectiveness of monetary policies. Such a process could evolve into a currency crisis or, with a short delay, an accompanying bank crisis.
