Turkey has embarked an extensive dis-inflation and stabilization program in December 1999. The programme exclusively relied on a nominally pegged (anchored) exchange rate system for dis-inflation and on fiscal austerity. In February 2001, however, Turkey experienced a severe financial crisis which necessiated the dismantling of the exchange rate anchor and a switch to a regime of free float. This article proposes a new methodology to measure exchange rate misalignment for Turkey over the period January 1992 to December 2001. In a single equation framework, the model estimates the real exchange rate within a time varying parameter model, where a return-to-normality assumption about the parameters is assumed. Contrary to common belief, it is found that, except the initial four months of the stabilization programme, the Turkish lira remained undervalued for most of 2000. Also, one observes a pattern where the lira has been overvalued after the financial crisis of 1994 until 1998, and has displayed a tendency of undervaluation after then.
