The Short Version
The claim is false. While standard trade theory predicts tariffs could strengthen a currency, the actual evidence from Trump's 2025 tariffs shows the opposite: the U.S. dollar depreciated. Federal Reserve research documents dollar weakening following the tariffs, and Brookings confirms a roughly 10% trade-weighted decline since Trump's second term began. The administration itself invoked emergency powers to prevent further dollar depreciation — an implicit admission that the tariffs caused weakness, not strength.
