Trump's tariff storm weighs on the dollar! Key signals herald a sea change in the global economic landscape

On Friday (May 30), the US dollar index showed a narrow seesaw trend in Asia, or recorded a fifth consecutive monthly decline. Senior traders have adjusted their positions in response to the "policy earthquake" triggered by Trump's tariff policy. It is particularly noteworthy that the Federal Reserve's most important PCE inflation indicator is about to be released tonight in the US Eastern Time. This report may be the final straw that breaks the dollar.

The judicial war triggered market panic

This week's dramatic turn in financial marekt began with the federal court's "midnight ruling". In the early hours of May 29th local time, the Washington Circuit Court of Appeals suddenly reinstated Trump's sweeping tariffs on imports. The ruling directly overturned the "unconstitutional" ruling made by the trade court the day before. The repeated policies caused Wall Street to be thrown into chaos. Dow futures plummeted 300 points after the news was announced, and a large amount of safe-haven funds poured into gold and Swiss francs.

Trump held an overnight press conference at his Mar-a-Lago resort in Florida, where he railed against the judicial system for "hindering American recovery" and threatened to fight to the Supreme Court. Holding the tariff list in hand, the controversial president stressed: "Multinational companies that want to move factories out of the United States must pay a fair price." This statement sent the shares of multinational companies such as Apple and Tesla tumbling.

The double whammy of economic alarm and debt crisis

Kyle Rodda, chief analyst at Capital Economics, said: "What we are seeing now is not the end of the trade dispute, but the beginning of a longer economic war." Data show that the number of initial jobless claims in the United States unexpectedly climbed to 268,000 last week, and the first-quarter GDP revision was also revised down to 1.1%. These are all confirming economists' fears of a "Trump recession".

More worrying are the red flags emanating from global debt markets. US 30-year bond auctions suffered a historic snub, with interest rates soaring to 4.85 per cent and the Bank of Japan forced to step in to suppress 10-year yields. Deutsche Bank reports that US and Japanese government debt has exceeded 135 per cent of GDP and 265 per cent of GDP respectively. This unsustainable fiscal situation is shaking the foundation of the dollar.

After the release of the data that the core CPI rose by 3.2% year-on-year in Tokyo in May, the yen jumped 0.3% in an instant. "The market is betting on the Bank of Japan to raise interest rates in July, which is in sharp contrast to the expectation that the Federal Reserve may cut interest rates." However, the dollar/yen monthly line still barely maintained a decline of 0.5%, mainly due to the safe-haven demand triggered by Trump's "America First" policy.

Countdown to the decisive battle

As the July 9 deadline for Trump's tariffs approaches, all eyes are on three key points: PCE data tonight, next week's OPEC + production meeting, and the G7 finance ministers' summit in mid-June. JPMorgan Chase warns that if core PCE gains exceed 0.4% month-on-month, the Federal Reserve may be forced to make a painful choice between inflation and recession.

The financial tsunami triggered by Mr. Trump's policies is far from over. When the tariff stick hits the debt ceiling and protectionism collides with global supply chains, the summer of 2025 is destined to go down in financial history. The only certainty is that the old order, built on the hegemony of the dollar, is shaking violently in this perfect storm.
