The cost of goods in general is increasing slowly, but tariffs probably aren’t a factor because they apply to a very small slice of the economy. That could change, though, if Trump follows through on the two threats he added to the announcement of the $200 billion in new tariffs. First, the tariffs will go up from 10 percent to 25 percent on Jan. 1 — a clear effort to force China to the negotiating table. And second, Trump said he’ll hit the rest of China’s exports to the United States — about $267 billion worth of goods — “if China takes retaliatory action against our farmers or other industries.”
