Donald Trump on Saturday escalated his trade push, announcing a 15% across-the-board tariff on imports despite a recent ruling by the Supreme Court of the United States that invalidated his earlier measures.

The announcement triggered volatility in digital assets. Bitcoin (BTC) dipped after Trump said the global tariff would be lifted to 15%, effective immediately, up from the 10% rate he had outlined following the court’s decision. The justices had determined that his previous tariffs, imposed under the International Emergency Economic Powers Act (IEEPA), exceeded his authority.

Posting on Truth Social, Trump labeled the ruling “anti-American” and made clear he intended to proceed with revised trade action.

Bitcoin initially gained roughly 0.5% on the headline but quickly reversed, sliding close to 1% before stabilizing around $68,000. Ether (ETH) also weakened, falling 0.45% to trade near $1,980.

The latest move underscores renewed uncertainty around U.S. trade policy, as Trump presses ahead with higher tariffs in defiance of the Supreme Court’s earlier decision.
