While the Dallas Fed Manufacturing Index tends to be a little less of a headline-maker than many of its macro-data peers, today's dismal report is worth paying attention to. The index turned negative for the first time this year, dropped to its lowest level in 7 months and missed expectations by the largest amount in 10 months. The drop from +10.8 to -3.4 is also the largest sequential drop in 11 months. Only the inventories sub-index rose (hardly a bright spot) as Production, Number of Employees, New Orders, and Capacity Utilization all plunged and the average workweek fell for the first time in months. The US decoupling myth continues to come apart at the seams and the likelihood of more easing (extreme or not) seems to be rising by the day - because that has worked so well in the past.
