Charles P. Kindleberger wrote that “asset price bubbles depend on the growth in credit”. This column looks at the acceleration of the US private label mortgage securitisation market in the US in the late summer of 2003, which disproportionately reduced the cost of financing by lenders that did not traditionally rely on deposit financing for mortgage lending. The sharp rise in lending in zip codes with greater exposure to such lenders generated a boom and bust in house prices. Easier credit also appears to have been a crucial ingredient in explaining bubble cities that experienced both house price and construction booms.

Commodity exporters have been both blessed and cursed by the boom-and-bust nature of commodity-price and demand swings. This column presents a new metric that computes the additional income arising from changes in the real purchasing value of output as a result of changes in relative prices. Focusing on Latin America, it’s clear that although its recent terms-of-trade boom is of similar magnitude to that seen in the 1970s, the associated income windfall has been much larger. The current weakening of external current-account balances in Latin America – even if driven by higher domestic investment – warrants close monitoring.
