The World Needs MORE Speculators
I struggle to understand how speculation is supposed to be both profitable and destabilizing all at once. Profitable speculation requires buying low and selling high. Destabilizing speculation requires the opposite: short-selling shares in a trough, thus deepening the trough, and betting that frothy shares will become frothier. In other words, destabilizing speculation means selling low and buying high. If that is a recipe for profit, I am missing something.
Profitable speculators, in contrast, are veritable philanthropists. When they think oil is going to become more expensive, they buy and hoard oil, or they buy oil futures, encouraging others to buy and hoard. This raises oil prices when they are relatively cheap and lowers them when they are relatively expensive.
True, when speculators make mistakes, that is destabilizing. But in the case of oil prices, it's hard to see that speculators are playing much of a role. For one thing, inventories don't seem to be rising. If the inventory data are correct, consumers were burning all that $135 oil.
The world needs more speculators, especially of the short-selling variety. More short sellers in the dot-com bubble of the late 1990s, and the housing bubbles of the past few years, would have added a welcome dose of stability and sanity.
