Perfect macroeconomic stability is achieved only in a graveyard. Coupled with free capital flows this recipe is downright dangerous. The sequence is simple and inevitable - but, luckily, fully reversible. This is a counter-cyclical Kenseyan reflex. Money is injected to a languishing economy through the budget.
Money supply is reduced sharply.
Where free capital flows are permitted - foreign speculative funds will drive down the exchange rates of the domestic currency versus foreign currencies. Where capital flows are more restricted, domestic corporations will borrow in foreign exchange and invest in high yielding domestic currency deposits and bonds. Both these things happen in the Czech Republic. They enjoy the difference between the high rates on koruna deposits offered courtesy the CNB and the much lower interest they pay to their lenders. An added bonus is the strengthening of the Czech koruna versus other currencies which provided the speculators with capital gains as well.
