Increases in wholesale prices of commodities get passed on to consumers in the form of higher gas prices, costlier airline tickets and more expensive food. Some experts say speculators aren't entirely to blame for price increases in commodities. They point to other factors, such as weather, supply disruptions and demand. Agricultural commodities such as corn and wheat have been subject for years to caps on speculative futures trading imposed by exchanges. Yet their prices have risen, experts say. The new limits on trading for 28 commodities and related financial instruments mark the first time the federal government has imposed broad curbs. Pope Benedict XVI and Howard Schultz, the CEO of Starbucks, are among the public figures who have recently denounced commodity speculation. Last week about 400 economists from 40 countries signed a letter to finance chiefs of the world's leading economies seeking curbs on speculative trading, which they say has driven food prices higher.
