The Dow Jones Industrial Average (DJIA) experienced significant volatility Monday amid escalating trade tensions. Initial market optimism stemming from speculation regarding a potential tariff extension was quickly dispelled by President Trump’s announcement of impending additional tariffs on Chinese goods. This development reversed earlier gains and triggered a sharp market decline. The DJIA opened substantially lower, breaching the 37,000 level for the first time since December 2023. This downturn followed China’s imposition of retaliatory tariffs on US goods, which were themselves a response to prior US tariffs. The broader US equity market also suffered losses, with the S&P 500 and Nasdaq Composite indices declining, reflecting widespread investor concern.
