Charles Gasparino, a Fox business correspondent, said on social media: "A number of CEOs have told their investment banks that the impact of tariffs will be felt in the next six to eight weeks. No one can say for sure what the outcome will be, but the next two months or so will be a critical period that will determine whether there is an economic slowdown or inflation. The real unknown is how long the economic shock will last if it does happen, and things are still developing."
