TRUMP’S IRAN TARIFF GAMBIT: A CALCULATED RISK THAT COULD RESHAPE GLOBAL TRADE

13 January 2026

Amid the chaos continuing to envelop and ravage Iran, where a large-scale protests sparked by currency collapse have been met by a brutal crackdown by authorities—with large-scale deaths and mass arrests reported—President Trump has announced immediate 25% tariffs on nations conducting business with Iran. The move introduces a new element of uncertainty into global commerce, with potentially significant ramifications for the hard-won US-China trade détente.

The tariffs target major economies including China, India, Turkey, the UAE and Brazil—all substantial Iranian trading partners. China faces particular exposure, having imported approximately 90% of Iran’s oil exports through independent refineries whilst maintaining over $9 billion in documented trade. The new levy could push cumulative US tariffs on Chinese goods from the current 30.8% to approximately 56%, threatening the fragile truce established at last October’s South Korea summit that granted Washington access to critical rare earth minerals.

The policy’s ambiguity—Trump provided no details on what constitutes “doing business” or how enforcement will proceed—creates immediate complications for global supply chains. India’s $1.34 billion bilateral trade with Iran, Turkey’s $5.68 billion commerce across their shared border, and Brazil’s $3 billion agricultural exports all fall within potential scope. The UAE’s role as a re-export hub for Iranian goods adds further complexity to implementation.

For China specifically, the stakes extend beyond trade metrics. Beijing secured rare earth export agreements and a presidential visit to China scheduled for April as part of the détente. Trump administration adviser Peter Navarro previously cautioned against escalating Chinese tariffs further, warning “we don’t want to get to a point where we hurt ourselves.” Whether carve-outs emerge remains unclear, though the White House has yet to publish legal authority or implementation details for the Iran-related levies.

As businesses navigate this evolving landscape, the incident underscores how rapidly geopolitical developments can reshape commercial calculations, requiring organisations to maintain strategic flexibility in an increasingly volatile trading environment.
