Not made a comment on this before as I have been in Udon for the last three months and am only just starting to catch up on all the posts I missed while I was away.
The current rate of THB v USD is a function of a number of factors and the current political uncertainties in Thailand is only one of those factors.
There are two main factors in the rise of THB against USD (plus a whole host of others too numerous to mention):
1. The Monetary Policy Committee of the Bank of Thailand has been tracking the rise in US interest rates and using the same reasons, however the rationale for the rise in the US rates does not apply in Thailand as the structure of the economies are simply not comparable.
2. The US budget deficit which is continuing to run out of control to even higher mind blowing levels.
The result of the two factors above has been a net appreciation in the THB of about 10% in the last nine months which (IMHO) is excessive at this time.
Just to expand a little and quantify the US budget deficit numbers, the following figures are extracted from the 2004 and 2005 "Financial Report of the United States Government" which is produced by the Financial Management Service Department of the US Treasury, website at
http://www.fms.treas.gov/fr/
The reported "Unified Budget Deficit" of the US in
billions of dollars for the last 3 years are: 374.8 (2003), 412.3 (2004) and 318.5 (2005) a total of 1,105.6 billion dollars (NB - these are the figures you see reported on CNN, BBC, Fox etc).
However the "Net Operating Cost" which is the real deficit in billions of dollars for the last 3 years are: 667.6 (2003), 615.6 (2004), and 760.0 (2005) a total of 2,043.2 billion dollars (NB - I have yet to find any media outlet report these numbers but these are the ones that the economists and money market professionals have in their financial models).
Although I said above that the appreciation of the THB against USD is excessive at this time, unfortunately (unless there is a dramatic change in the US budget deficit) in the medium term of say two to five years it is more than likely that the appreciation will (IMHO) be even more and could result in the THB operating in the range of 30 to 35 against the USD.
