The key here is that these high interest rates carry with them a high lock-in premium which makes it difficult to reduce them without causing substantial pain to the currency. Add to this that as long as interest rates stay in this territory the incentive to borrow in foreign currency remains very appealing. In fact, the incentive structure here is quite disruptive as many of these economies have higher rates on domestic currency deposits and lower rates on foreign credit. This incites consumers and companies to place their deposits in local currency while funding themselves in foreign currency. Finally, there is of course the more standard economics 1-0-1 point that whatever nominal rate is ascribed to a currency and an economy the latter needs to be able to provide the structural demand for which to satisfy the yield. Otherwise you just pour more gasoline on an already raging bonfire.

Obviously, as long as the local currency remains strong and on an upwards march or the trading band is kept in place the show goes on. But the longer this structure lingers the more difficult it will be to break free; and break free they must since I am quite sure that Eurozone membership is off, for the immediate future at least. 

Another more hard hitting point would simply be that whatever growth momentum these economies had going into 2008 it is now steadily levelling off. Now, these economies need to rebalance their external accounts at the same time as they labour under the yoke of slowing growth, high interest rates which are difficult to reduce and/or a quasi fixed exchange rate to the Euro. Can you feel the chilling cold of deflation blowing across the Urals? I can.

Basically, the past years' rapid process of nominal convergence will now need to be kicked into reverse, since it is quite obvious that many CEE economies have been riding a blade too tough.

Be Careful Indeed

Last time I massaged this specific topic I summarised by ominously stating that the CEE economies and their central banks should be careful what they wished for in terms of using higher interest rates and subsequent nominal appreciation of their currencies to flush out inflation. The key point was that the effect would likely be limited and only further worsen the imbalances in the economies. And thus, here we are.

Another more subtle point in the context of market reactions would be the boomerang effect which comes from the currency appreciation as interest rates are increased (and the peg/band abandoned) to the subsequent plunge when the economic tide turns. In line with the change in global sentiment towards growth and deflation (see e.g. here) and the fact that other hitherto strong yielders (e.g. the Kiwi and Aussie) are beginning to falter we may be at an inflection point in the whole discourse of upwards movement in CEE currencies. Stephen Jen's recent tour of global FX markets is a fine addition to this argument.

As ever, this is obviously still a dilemma for most of these economies since inflation continues to rage ahead. In Romania for example the PPI rose at its highest pace since 2004. However, as long as the credit tap stays open and as long as the purchasing power is increasing so will the the demands for higher wages stay strong. This is particularly true in the context of the CEE economies as these are in possession of structurally broken population pyramids after two decades worth of lowest low fertility and, in the cast of the latter decade, net outward migration. 

The main point I would like to emphasise here is that correction is coming and that it will only become harder the higher the currencies move upwards. In a more general light this correction will not be a small one and it most certainly will not be felt exclusively in Eastern Europe. Basically, the big hidden data point in all of this is the dependence of Germany on CEE imports. So far, this has moved along just nicely but Germany is in for a rude awakening once the link breaks ... and break, I am afraid, it will.
