Currency market whiplashed on tariff, DeepSeek concerns
TOKYO (Reuters) -The dollar firmed against the yen and euro on Tuesday on new U.S. tariff threats, giving traders little time to catch their breath after Monday's big risk-off moves on concerns that U.S. dominance in artificial intelligence technology may be wavering. Any market relief that President Donald Trump stopped short of hiking tariffs on U.S. trading partners immediately after taking office last week has quickly faded. Trump said he planned to impose tariffs on imported computer chips, pharmaceuticals and steel in an effort to get the producers to make them in the United States.
