This is undoubtedly a prosperous period for the world economy, but the recent volatility in global stock markets is an indicator that times may be changing. The World Bank has forecast global economic growth of 3.1 percent for 2018, which will obviously benefit businesses. At the same time, an improving business environment brings with it the prospects of wage inflation, rising interest rates, and the end of cheap money. A couple of weeks ago, U.S. stocks reacted dramatically to figures that showed U.S. wages rising faster than expected. This clearly demonstrated how jittery the markets are about the end of a loose monetary policy.
