Markets and the heady spell of cheap money

The world's stock markets are at an all-time high, but could anything shatter their optimism?

Last week saw global stock markets close at all-time highs, having smashed several records already this year. The MSCI world index, which tracks shares in 45 countries, hit a fourth consecutive record on Friday. Driven by stronger jobs data, the Dow Jones (see graph) finished above 17,000 and the broader S&P 500 index hit another record, while falling just shy of the psychologically important 2,000 mark. On the bond market, yields remain low.
