In banking, the recognition of a “linkage” problem was one of the reasons for the formation of the Federal Reserve System. Before the Fed was established, the failure of weak banks would sometimes put sudden and unanticipated liquidity demands on previously-strong banks, causing them to fail in turn. The Fed now insulates the strong from the troubles of the weak. But there is no central bank assigned to the job of preventing the dominoes toppling in insurance or derivatives. In these industries, firms that are fundamentally solid can become troubled simply because of the travails of other firms further down the chain. When a “chain reaction” threat exists within an industry, it pays to minimize links of any kind. That’s how we conduct our reinsurance business, and it’s one reason we are exiting derivatives.
在金融体系中，早期发现到连锁反应的问题严重性是联邦准备理事会成立的主要原因之一，在联准会成立以前，体质不佳的银行倒闭有时可能会对一些原本体质还不错的银行造成突然没有预期到的流动性压力，导致它们跟着出现问题，联准会于是建立一道防火墙将有问题的金融机构隔绝开，但是在保险业或是衍生性金融商品交易，却没有类似中央银行的控管机制来防止骨牌效应的发生，在这些产业，一家原本体质不错的公司很有可能因为其它公司发生问题而受到拖累，当这种连锁反应的威胁存在在产业中时，就绝对有必要尽量降低彼此间的牵连，这正是我们目前在再保业采取的做法，同样这也是我们选择退出衍生性金融商品交易的原因之一。
