The advantage of such bonds is that in the event of a decline in the world price of the underlying commodity, the debt-to-export ratio need not rise. The cost of debt service adjusts automatically, without the severe disruption that results from loss of confidence, crisis, debt restructuring, and so forth.
这些债券的好处在于，当基础商品的世界价格下跌时，债务-出口比率不一定会上升。债务维持成本可以自动调整而不会因失去信心、爆发危机和债务重组之类的事情产生重大后果。
