"#Japan’s exchange operator briefly called a halt to trading in Nikkei stock futures on Monday morning because of a sharp fall triggered by President Trump’s tariffs.
The “circuit breaker” system calls for a 10-minute pause in trading when the widely traded #Nikkei225 futures product is poised to rise or fall more than 8%. The product represents a bet on the direction of the #NikkeiStockAverage of 225 issues. The circuit breaker kicked in at 8:45 a.m. Tokyo time for the Nikkei 225 and several other futures contracts, and it ended 10 minutes later. Spot trading—direct buying and selling of shares on the #TokyoStockExchange—wasn’t affected. The spot Nikkei 225 index was down about 6% Monday morning, recovering somewhat after earlier falling nearly 9%."
TL;DR:
Even though the stock drop happened in Japan, it was directly caused by a U.S. policy decision. For the average American, it’s a reminder that global markets are interconnected and that decisions made by our government can have far-reaching economic consequences, both abroad and at home.
