That sends stocks up further, making investors even wealthier, so they spend even more. And so on it goes. This is what Soros calls a “reflexive process” — a feedback loop: a change in stock prices has caused a change in company fundamentals which, in turn, justifies a further rise in stock prices. And so on.
You have no doubt heard of this particular reflexive process. Academics have written about it; even the Federal Reserve has issued a paper on it. It’s known as “The Wealth Effect.”
Reflexivity is a feedback loop: perceptions change facts; and facts change perceptions. As happened when the Thai baht collapsed in 1997.
In July 1997 the Central Bank of Thailand let its currency float. The bank expected a devaluation of around 20%; but by December the baht collapsed from 26 to the US dollar to over 50, a fall of more than 50%.
The bank had figured out that the baht was “really worth” around 32 to the dollar. Which it may well have been according to the theoretical models of currency valuation. What the bank failed to take into account was that floating the baht set in motion a self-reinforcing process of reflexivity that sent the currency into free-fall.
Thailand was one of the “Asian Tigers,” a country that was developing rapidly and was seen to be following in Japan’s footsteps. Fixed by the government to the US dollar, the Thai baht was considered a stable currency. So international bankers were happy to lend Thai companies billions of US dollars. And the Thais were happy to borrow them because US dollar interest rates were lower.
When the currency collapsed, the value of the US dollar debts companies had to repay suddenly exploded…when measured in baht. The fundamentals had changed.
Seeing this investors dumped their Thai stocks. As they exited, foreigners converted their baht into dollars and took them home. The baht crumbled some more. More and more Thai companies looked like they would never be able to repay their debts. Both Thais and foreigners kept selling.
Thai companies cut back and sacked workers. Unemployment skyrocketed; workers had less to spend — and those who still had money to spend held onto it from fear of uncertainty. The Thai economy tanked…and the outlook for many large Thai companies, even those with no significant dollar debts, began to look more and more precarious.
As the baht fell, the Thai economy imploded — and the baht fell some more. A change in market prices had caused a change in market prices.
