Many people argue that derivatives reduce systemic problems, in that participants who can’t bear certain risks are able to transfer them to stronger hands. These people believe that derivatives act to stabilize the economy, facilitate trade, and eliminate bumps for individual participants. And, on a micro level, what they say is often true. Indeed, at Berkshire, I sometimes engage in large-scale derivatives transactions in order to facilitate certain investment strategies.
许多人声称衍生性金融商品交易可以有效降低系统风险，透过这类交易让原本无法承担特定风险的人可以将风险移转到他人身上，这些人相信衍生性金融商品成为稳定经济的力量、让商业交易得以遂行同时降低个别参与者的变量，就个体层面而言，他们的说法或许确是事实，就像是在Berkshire，我有时也会搭配一些大规模的衍生性金融商品交易好让某些投资策略得以遂行。
Charlie and I believe, however, that the macro picture is dangerous and getting more so. Large amounts of risk, particularly credit risk, have become concentrated in the hands of relatively few derivatives dealers, who in addition trade extensively with one other. The troubles of one could quickly infect the others. On top of that, these dealers are owed huge amounts by non-dealer counterparties. Some of these counterparties, as I’ve mentioned, are linked in ways that could cause them to contemporaneously run into a problem because of a single event (such as the implosion of the telecom industry or the precipitous decline in the value of merchant power projects). Linkage, when it suddenly surfaces, can trigger serious systemic problems.
