Despite its US$40 trillion debt and ongoing bond troubles, the underlying US economy appears to be motoring along fine. The Services PMI, which tracks the goods and services sector, came in at 55.4, above expectations of 54.3. The economy also added 162,000 new jobs in a month, more than triple expectations. There could be volatility ahead, however, with new inflation data out this week, and the CLARITY vote and US Federal Reserve interest rate decision next week. The strong jobs figures increased expectations of a rate rise, and markets dipped in response.
