FINANCIAL markets are supposed to be the font of all wisdom, weighing up the information available and condensing it into a set of prices. Investors are presumed to have an insight into the future—falling bond yields are seen as a sign that the economy is slowing, for example.
But are investors that clever when it comes to politics? Gambling markets show how they assess political risk. They expected the Remain campaign to win the Brexit referendum and Hillary Clinton to become America’s president, and were proved wrong. Indeed, on Brexit, the mass of gamblers (the general public, in other words) backed Leave, but the odds were skewed by some wealthy punters who favoured Remain. Those rich gamblers were probably people who trade in financial markets; the plunge in the pound after the result suggests that most investors were caught on the hop.
