Trade in commodity derivatives – such as oil futures – has grown tremendously over the last few decades. Some believe that the "financialisation" of commodity markets has made them more efficient.

Why did the world economy plunge into the worst recession since the Great Depression? This column argues that economic fundamentals do not explain the global crisis. But they did play a role. Events such as the fall of Lehman Brothers can become focal points for investors’ risk perceptions, changing the way the fundamentals are interpreted. This can lead to “risk panics” – self-fulfilling spikes in risk and a collapse in asset prices.
