My contacts in various parts of the manufacturing sector tell me they're already pulling back but keeping it quiet. Nobody wants to be the first to proclaim gloom and doom.
I have worked in several industries so I have a rather large network of contractor contacts and outsourcing services. I usually get a handful of cold requests and service offers per month, but this year my inbox has received that number of requests per week or even more. In a good economy these businesses can barely keep up with their workload, thus this probably means that things are cooling off. Asian businesses and companies that rely on them moreso due to the uncertainty of the tariffs and trade war. It feels very much like 2007-2008, although that may be subjective on my part.
