After a rough day in Bangkok, stock exchanges and currencies were slammed worldwide, as oil prices hit fresh 12-year lows.
Global stock price plunge may just be "herding" behavior of stock traders, but if it lasts for long watch out: "low stock prices lasting for long lead to lower consumption, lower demand, and, potentially, to a recession."
STOCK MARKET & ECONOMICS
Global stock collapse: Oil, China or just stock market traders?
A sharp fall in stock prices at stock markets around the world is a major news story today (see here).
A collapse in oil prices and the stalling of economic growth in China are cited as reasons for the sharp fall.
There is, however, another possible explanation.
The behaviour of stock traders themselves may have caused the fall in stock prices.
Should we worry or not?
Olivier Blanchard, former chief economist at the IMF and professor of economics at MIT, assesses the situation:
"The Price of Oil, China, and Stock Market Herding: The stock market movements of the last two weeks are puzzling.
"Take the China explanation.
"A collapse of growth in China would indeed be a world changing event. But there is just no evidence of such a collapse. At most there is suggestive evidence of a mild slowdown, and even that is far from certain...
"Take the oil price explanation. It is even more puzzling.
"Traditionally, it was taken for granted that a decrease in the price of oil was good news for oil importing countries such as the United States [or Thailand]. ...
"We learned in the last year that, in the short run, the adverse effect on investment on energy producing firms could come quickly and temporarily slow down the effect, but this surely does not undo the general conclusion [that oil price decreases are good news, making energy costs lower].
"Yet the [news] headlines are now about low oil prices leading to low stock prices. ...
"Maybe we should not believe the [stock] market commentaries [in the news]
"Maybe it was neither oil nor China.
"Maybe what we are seeing is a delayed reaction to the slowdown in the world economy... Maybe…
HERDING BEHAVIOUR IN THE STOCK MARKET
"I think the explanation is largely elsewhere.
"I believe that to a large extent, herding [among stock traders in the stock market] is at play.
"If other investors sell, it must be because they know something you do not know.
"Thus, you should sell, and you do, and so down go stock prices.
"Perhaps because we have entered a period of higher uncertainty. ...
TWO SCENARIOS FROM ECONOMICS
"So how much should we worry?
"This is where economics ... gives the dreaded two-handed answer.
"If it becomes clear within a few days or a few weeks that fundamentals are in fact not so bad, stock prices will recover...
"If, however, the stock market slump lasts longer or gets worse, it can become self-fulfilling [a self-fulfilling prophecy].
"Low stock prices lasting for long lead to lower consumption, lower demand, and, potentially, to a recession.
"The ability of the Fed [the US central bank], fresh out of the zero lower bound [interest rates close to zero under Quantitative Easing (QE) monetary policy], to counteract a slowdown in demand remains limited.
One has to hope for the first scenario [that global economic fundamentals are, in fact, good], but worry about the second [scenario, that a stock slump might last for a long time and get worse].
