U.S. auto dealers are reporting sharp drops in new and used vehicle supplies, according to CNBC. Consumers are rushing to buy ahead of potential price hikes from President Donald Trump’s new 25% tariffs on imported vehicles. New car inventory fell from a nearly 90-day supply in early March to 70 days, and used car supply dropping to 39 days, according to Cox Automotive. "Days’ supply" means how long dealers can keep selling cars at the current pace before they run out, assuming no new stock arrives. Higher-than-expected auto sales are helping the industry, but analysts worry they could stall once tariff-free inventory runs out.
