Court Ruling on Trump-Era Tariffs Triggers Bond Rout Amid U.S.-China Tech Standoff

A sharp sell-off in U.S. government bonds is underway after a pivotal court ruling upended key Trump-era tariffs, intensifying investor anxiety already inflamed by deepening U.S.-China hostilities in high-tech industries and academia.

The 10-year Treasury yield has spiked to 4.50%, while the 30-year yield surged past 5%, marking a swift repricing of risk in the bond market. The move followed a decision by the U.S. Court of International Trade, which declared that the blanket tariffs imposed by former President Donald Trump were unconstitutional.

According to court findings, the administration overstepped its authority by leveraging emergency economic powers to impose wide-reaching trade penalties—powers the court said were never intended for such use. While the ruling voids the general 10% and retaliatory tariffs, it leaves intact more narrowly targeted measures, such as those on steel and automotive imports. The White House has signaled its intent to appeal.

Yet the legal development is only part of the story. Markets are also reacting to rising strategic tensions between the world’s two largest economies. The U.S. has recently escalated restrictions on China, ordering chipmakers to cease sales of advanced semiconductors, blocking access to essential chip design tools and jet engine technologies, and even beginning to revoke visas for Chinese nationals in sensitive academic fields.

These actions suggest a broader decoupling effort is accelerating, with Washington taking a harder line on technological sovereignty and national security concerns.

In currency markets, the Dollar Index (DXY) has risen from 98 to 100, reflecting a classic flight-to-safety response as investors seek stability amid growing international friction. Meanwhile, both bitcoin—trading near $104,309—and gold are holding steady, as traders await the next major policy shift or geopolitical headline.

The combination of legal uncertainty, aggressive export controls, and tightening visa policies points to a turbulent road ahead for global markets—and investors are clearly taking notice.
