This is a chart of the average annual buy/sell rate for GBP/THB from 1981 (my earliest data) to 2009 – personally I find charts using longer-term average data a useful tool as they tend to smooth out and remove most of the distractions of the peaks and troughs of shorter-term data.

To try and give some indication as to how 2010 compares with prior years I added two columns (in the red dotted rectangle on the right) these are firstly the average for the first half of 2010 and secondly today’s closing rate in Thailand.
Note: the trend lines on my charts should not be interpreted as anything other than a pictorial representation of historical mathematical data – it is not any statement of under-value or over-value.
Please note that, because I have included both a half year average and latest rate for 2010, the excel calculation of the upward trend in the above chart is actually understated - the actual trend to 2009 would show a value of 69 in 2009.
The next chart gives another representation looking at the most recent years of 2001 to 2009 – as above the downward trend is actually understated - the actual trend to 2009 would show a value of 62.6 in 2009 (a figure which almost certainly this year will be somewhat lower).

While I’m not generally in the habit of crystal ball gazing, when I take ALL the comparative economic and financial data (that I’m aware of) from the major currency zones my view (currently) is that:
1. The GBP will continue to rise for the remainder of this year.
2. The EUR will also rise (but to a lesser degree).
3. The USD will fall, safe-haven status is more apparent than real, and so far nothing other than lip-service is being paid to the elimination of the crippling fiscal deficits (both at federal and state level) and the trade deficit.
Additionally, from the way that the THB is currently controlled, I believe that the THB will continue its rise against the USD (although having said that, I believe that the THB is actually already over-valued – but I don’t control the market).
Now that I've made some predictions I expect that some stupid simple thing that I've not considered will occur to prove me wrong
