In the US there is a significant downturn in a handful of industries that are the first to decline in a recession. For instance, RV/ camper sales are in a post-boom decline. I'm not saying that means there is an incoming recession as a number of reasons could be at play likethe market simply correcting itself, but things like that tend to be why people think one is impending.
There are many factors such as gas prices that need to be considered as well when it comes to RV sales for example. Maybe people are now able to fly and stay in hotels instead. Maybe more people know that the best days of owning an RV are the day you buy it and the day you sell it.
Well the yield curve did invert recently. Then reversed.
