“What onions teach us about oil prices” na CNN
The bulbous root is the only commodity for which futures trading is banned. Back in 1958, onion growers convinced themselves that futures traders (and not the new farms sprouting up in Wisconsin) were responsible for falling onion prices, so they lobbied an up-and-coming Michigan Congressman named Gerald Ford [*] to push through a law banning all futures trading in onions. The law still stands.
And yet even with no traders to blame, the volatility in onion prices makes the swings in oil and corn look tame, reinforcing academics’ belief that futures trading diminishes extreme price swings. Since 2006, oil prices have risen 100%, and corn is up 300%. But onion prices soared 400% between October 2006 and April 2007, when weather reduced crops, according to the U.S. Department of Agriculture, only to crash 96% by March 2008 on overproduction and then rebound 300% by this past April.
The volatility has been so extreme that the son of one of the original onion growers who lobbied Congress for the trading ban now thinks the onion market would operate more smoothly if a futures contract were in place.

Outra semelhança é que aqui há poucos anos houve grandes revoltas populares na Índia devido ao preço das cebolas ter atingido níveis extremamente altos. (As cebolas são um ingrediente crucial da culinária indiana.)
