President Donald Trump has announced that any country doing business with the Islamic Republic of Iran will, with immediate effect, face a 25 per cent tariff on all trade with the United States in a bold expansion of his administration’s trade strategy. The measure, unveiled on Monday, is intended to increase economic pressure on Tehran in response to Iran’s violent suppression of domestic protests and what the White House describes as “harmful actions” by the Iranian government.
In a statement posted on his social media platform, Trump said the tariff imposition was “final and conclusive” and that the United States would levy the additional duty on any country that maintains trade relations with Iran. The president has framed the decision as part of a broader campaign to limit the financial resources available to the Iranian regime amid widespread unrest.
The unrest in Iran began late last year – triggered by surging inflation, which has soared above 40 per cent, and a sharp fall in the value of the Iranian rial – leading to protests across the country demanding political change. Security forces have responded with force, prompting international criticism and calls for sanctions from Washington.
Although the policy’s formal legal basis and detailed implementation mechanisms have not been published by the White House, the announcement has already sent ripples through global trading networks. Economists warn that the new tariff could disrupt established supply chains and exacerbate tensions between the United States and key trading partners, particularly those with deep economic ties to Iran.
Nigeria appears to be among the countries caught up in the latest development. In December, Abuja and Tehran reaffirmed their intention to deepen bilateral cooperation across a range of sectors, including trade, energy and investment, during a high-level meeting between Nigerian foreign ministry officials and the Iranian ambassador. Iran also regards Nigeria as an important partner and gateway to broader West African engagement.
The tariff move comes after previous tensions in U.S.–Nigeria trade relations. Last year, Washington introduced a 14 per cent tariff on Nigerian exports in response to import restrictions on American goods, prompting Abuja to engage in consultations with the World Trade Organisation and U.S. counterparts.
Critics argue that Trump’s escalating tariff measures risk sparking broader trade conflicts and could have unintended consequences for global markets. Others say they reflect a growing trend toward protectionist policies by major economies. As the new 25 per cent levy takes effect, the international community is bracing for the economic and diplomatic fallout that may follow.
