ok let me explain again. Some people seem to think its a good idea to change a good amount of money from sterling into Turkish lira and then put into a high interest bank account here in Turkey. They get the interest monthly and use that as an income but not touching the original amount.
ie....when I first arrived the pound lira rate was 8900. Now the rate is 2.8 (or 2,800,000 in old money).
100,000 pounds exchanged to Turkish lira at the rate of 8900 = 890,000,000 old turkish lira.
890,000,000 is now worth 890 lira in todays money. (1,000,000 old lira = 1 new lira)
890 lira changed into pounds at the rate of 2.8 = 318 pounds.
remember although you would have been getting interest monthly to keep up but you would have withdrawn it every month as that was your income.
Those people that have been living here since the Tansu Ciller days, knows how the Turkish currency can lose value by more then 50% overnight!! Nobody kept their investments in lira but rather in marks or dollars or even more popular, gold, especially cumhurriyet gold.
