The Skyscraper Index is a concept put forward in January 1999 by Andrew Lawrence, research director at Dresdner Kleinwort Wasserstein, which showed that the world's tallest buildings have risen on the eve of economic downturns. Business cycles and skyscraper construction correlate in such a way that investment in skyscrapers peaks when cyclical growth is exhausted and the economy is ready for recession. Mark Thornton's Skyscraper Index Model successfully sent a signal of the Late-2000s financial crisis at the beginning of August 2007.Now comes the news that China plans to build the world's tallest building in just three months! It's a contrarian signal that indicates that an economy is topping out.
The Skyscraper Index is admittedly an imperfect indicator, largely because there are so few data points and the results could be attributable to data fitting. Nevertheless, the ideas are highly intuitive, as Wikipedia explains:
The intuitively simple concept, publicized by business press in 1999, has been cross-checked within the framework of the Austrian Business Cycle Theory, itself borrowing on Richard Cantillon's eighteenth-century theories. Mark Thornton (2005) listed three Cantillon effects that make skyscraper index valid. First, a decline in interest rates at the onset of a boom drives land prices. Second, a decline in interest rates allows increase in average size of a firm, creating demand for larger office spaces. Third, low interest rates provide investment to construction technologies that enable developers to break earlier records. All three factors peak at the end of growth periodInterestingly, the market peak and financial crisis that follow seems to occur sometime between the planning of the building and its completion. Consider, for example, the Empire State Building, which began in January 1930 - after the stock market crash. The Petronas Towers in Malaysia was completed in 1998, a year after the onset of the Asian Crisis. Here is more about the Skyscraper Index from Barclays (via The Big Picture).
To be sure, a peak indicated by the Skyscraper Index doesn't mean that the lights have permanently gone out on the country which constructed the world's tallest building. The United States went on to continue its growth and assume the mantle of global leadership after the Great Depression. The Malaysian economy of today, or the economy of Asia, can't exactly be characterized today as a black hole either.
For today's investor, I remain of the belief that, in terms of the effect on markets, China is at center stage and Europe is the sideshow (see Focus on China, not Europe). This latest signal from the Skyscraper Index confirms that view. If Europe were to stabilize itself but China lands hard, what happens in Greece or Spain won't matter very much.
