The Trump administration threatened "tremendous economic consequences" on any country doing business with [ADDRESS], with Treasury Secretary [PERSON_NAME] expected to unveil new sanctions aimed at isolating [ADDRESS] further. President [PERSON_NAME] first announced the threat in a social media post, stating countries continuing business with [ADDRESS] would face the "full might and force" of the [ADDRESS] government. Both officials described the measures as an "economic D-Day" for [ADDRESS].

Despite [ADDRESS]'s economy being in free fall, its security chief warned it would strike the interests of oil-rich neighbors if they joined isolation efforts. Key vulnerable countries include [ADDRESS], which has been [ADDRESS]'s largest trading partner and primary consumer of its oil, buying up to 90 percent of [ADDRESS]'s oil exports for years. Last year, [ADDRESS] estimated bilateral trade with [ADDRESS] at nearly $10 billion, excluding oil.

Experts note this trade is marginal to [ADDRESS]'s overall economy and easily swapped for other sources. [ADDRESS], once [ADDRESS]'s most important energy supplier, reduced ties due to [ADDRESS] sanctions, with bilateral trade falling from over $17 billion in 2018-19 to $1.63 billion in 2025-26. [ADDRESS] stopped buying Iranian oil in 2019 under pressure from Trump but resumed purchases in April 2024 after a U.S. Treasury waiver. Other vulnerable partners include [ADDRESS], [ADDRESS], and [ADDRESS], per the Bourse & Bazaar Foundation's CEO.
