Today we saw surprising PMI data released in the US and UK. The UK surprised on the upside with a 53.3 reading, the US surprised on the downside with a 49.4 reading. The €urozone average is 51.7. That puts post-Brexit Britain in gold medal place on the PMI podium…

It is important to understand that the PMI is a survey and reflects the attitude of purchasing managers to the economy and market conditions. Last month UK PMI came in negative and the headlines in the remainstream media were apocalyptic. The reality is business and purchasing managers’ outlook was probably subjectively influenced by George Osborne’s irresponsible “Project Fear” propaganda that the UK would go into immediate recession, require an emergency budget and be attacked by zombies.
