Trump's legal loophole around the Supreme Court is keeping inflation alive – and trapping Bitcoin in the Fed's crosshairs
Despite the Supreme Court rejecting Trump's authority to impose tariffs using an emergency law, the administration has found a legal loophole that keeps inflation alive and places Bitcoin directly in the Federal Reserve's crosshairs. This maneuver is exacerbating inflationary pressures and creating a hostile environment for the cryptocurrency market. The court decision initially seemed like a clear roadblock to Trump's trade policies, but the administration has found an alternative path, maintaining tariffs that contribute to inflation.
