The Supreme Court's decision invalidating nearly half of the Trump administration's tariffs is not the free-trade triumph it first appears. LPL Research identifies eight critical caveats. While importers gain immediate relief from reciprocal tariffs on Canada, Mexico, and China, the ruling's core impact is limited.

President Trump swiftly countered with a new 10% global tariff, signaling the administration's intent to pursue alternative legal avenues like Section 122 or 301. LPL estimates up to 90% of the 'illegal' tariffs could return by summer, leaving significant uncertainty. The Treasury faces a $175 billion refund cliff if lower courts mandate repayments, adding massive borrowing pressure. Inflation impacts are muted, as tariffs historically contributed little to price hikes. The Federal Reserve's rate path remains largely unchanged, though the U.S. Dollar may soften.

Investors should avoid chasing short-lived relief rallies; instead, focus on sectors like semiconductors and homebuilders. This complex outcome underscores that the trade landscape remains volatile.
