Trump Shifts to Section 122 at 15%, Samsung Reclaims Global DRAM Lead | February 23, 2026

Investment Implications

Section 122 Tariff Pivot Creates a 150-Day Window of Uncertainty

One day after the Supreme Court ruled IEEPA tariffs unconstitutional, President Trump raised global tariffs to 15% under a new legal basis — Section 122. This provision has never been invoked by any president, and it expires automatically after 150 days without congressional extension. The trade environment just got meaningfully more uncertain.

The global tariff, raised overnight from 10% to 15%, rests on Section 122 of the Trade Act of 1974 and expires automatically after 150 days without congressional approval. Critical minerals, metals, and energy products are exempt, and Taiwan semiconductors received separate Section 232 most-favored-nation treatment.

In the context of existing trends, the securitization of economics continues to reshape global value chains from a cost-optimization to a risk-management framework, with protectionist measures on critical inputs structurally intensifying. The fact that US Customs and Border Protection collected over $133 billion during the IEEPA tariff period through December 2025 underscores the growing fiscal significance of tariff revenue.

The critical variable for investors is the 150-day clock. If Congress does not extend the tariffs by mid-July, they expire automatically — but if extension legislation passes, this becomes a long-term tariff regime. Critical minerals, metals, and energy are exempt, and Taiwan semiconductors received Section 232 most-favored-nation status, though whether the same exemption applies to South Korean semiconductors remains unconfirmed. Autos and general manufacturing exports face a flat 15% global tariff, and the $350 billion US-Korea investment commitment opens the door to separate bilateral negotiations. Korean companies need to manage tariff volatility over the 150-day window while closely tracking potential exemption expansions and congressional developments.
