In hindsight, absolutely everyone seems to have made a catastrophic misdiagnosis of the problem, one that resulted in Thailand's getting insufficient treatment and in exposing other countries to the contagion. The misdiagnosis was twofold: first, that Thailand probably faced a typical temporary downturn, rather than a staggering depression that would last for years; second, that the problem was largely confined to Thailand rather than the beginnings of a serious global crisis.
I would argue that financial liberalization created great difficulties for Thailand at this time; however, in today’s world it’s very difficult to imagine Thailand without the giant foreign hotels and tourism market. The other issue that Thailand demonstrates here is that liberalization linked multiple countries and now our economies are intertwined. If one country's currency suddenly depreciates or even crashes in the longer term, countries other than the source will be affected.
