The earlier release of the Chicago PMI was somewhat disappointing with the 55.2 missing both the consensus forecasts and the prior reading. However in recent minutes a revision to this print has been announced which has seen a rise in the US dollar with USDJPY popping up by around 25 pips in the minutes since the release. 

The revision states that the correct reading was in fact 59.4 which is obviously now higher than both the forecast and prior. In fact 59.4 would represent the highest number since January 2015 and would be considered a strong rather than weak data point.
