In mid 2010 the Turkish central bank decided to introduce a policy that increased uncertainty in interest rates hoping that would stop foreign investors who were pouring money into the country in search of a quick buck. That’s right. ‘Keep calm and carry on’ was replaced by ‘Keep them guessing.’
The Turkish economy was overheating. Money poured into the country from foreign investors attracted by a strong economy and high yields. A lending boom resulted in excessive growth along with an appreciating exchange rate and widening current account deficit. While evidence of success, these kinds of capital inflows are a headache policymakers would rather avoid, as they expose a country to risks that affect the economy and financial system as a whole, while undermining the objective of controlling inflation.
