I like it.
40 baht to the dollar was the exchange rate when I first visited Thailand,
if it gets to that point again I won't complain.
I do wonder about:
"The sliding baht fell to below 37 to the US dollar, a key psychological barrier, raising speculation that it could further weaken to 40 per dollar."
If multiple factors determine the exchange rate, whose psychology is at play in passing a psychological barrier?
Not a rhetorical question, I really wonder about this.
