US dollar rallies over 0.2% as stalled Iran talks fuel oil supply fears

The US dollar strengthened broadly on Tuesday after hopes for a ceasefire between the US and Iran faded, pushing oil prices higher and compounding fears of persistent inflation. The dollar index, a measure of the currency against six peers, rose 0.2 percent to 98.17, reflecting a risk-off mood as traders reassessed the likelihood of a diplomatic breakthrough.

"Optimism regarding an imminent (peace) deal seems to be fading again," Suvro Sarkar, an energy sector team lead at DBS Bank, said. The currency market's cautious turn came after US President Donald Trump declared the current ceasefire "on life support," citing Tehran's rejection of a US proposal and its insistence on a list of demands Washington views as non-starters.

The dollar's strength was felt across the board, with the euro weakening 0.24 percent to $1.1754 and sterling dipping 0.26 percent to $1.3575. The move coincided with a jump in oil prices, as the diplomatic stalemate renewed concerns about the security of passage through the Strait of Hormuz, a chokepoint for about a fifth of global oil and gas flows. Brent crude futures climbed 0.8 percent to $105.07 a barrel, while West Texas Intermediate gained one percent to $99.06.

The breakdown in talks puts the global economy in a precarious position, threatening to prolong supply disruptions that have already hit consumers and industries. The situation recalls the 2022 gas crisis in Europe, where reduced supplies led to an inflationary shock. Today, however, the market has a new stabilizing force.

Saudi Arabia's Red Sea Lifeline

Amid the turmoil, Saudi Arabia's ability to export crude via its East-West pipeline to the Red Sea has become a critical buffer against more extreme price volatility. Kristijonas Gedvilas, CEO of the European Chamber of Commerce in Saudi Arabia, said the Kingdom's dual-coast export capability provides a crucial safeguard for global energy markets.

"The primary consequence of Hormuz-related disruptions for Europe is not a direct supply shortage, but rather upward pressure on global oil and gas prices," Gedvilas said. He noted that while the EU imports around 10 percent of its oil from the Gulf, the corridor’s contribution to market continuity has a real, if indirect, effect on European energy costs. This strategic resilience, backed by a production capacity of around 12 million barrels per day, reinforces Saudi Arabia's role as a stabilizing force.

Shipping and Inflation Under Pressure

The impact of the Hormuz disruption is already rippling through global supply chains. The shipping industry is facing a squeeze on bunker fuel, the lifeblood of maritime transport. In Singapore, the world's largest refueling hub, prices for the fuel have surged from around $500 to over $800 per metric ton since the conflict began, according to data from commodity site OilPrice.

This surge in operational costs is forcing shippers to take drastic measures, such as slowing vessel speeds by an average of two percent to conserve fuel. Experts warn these costs will inevitably be passed on to consumers. "Bunker fuel shortages tend to feed through to shipping costs more quickly than many other cost pressures,” said Oliver Miloschewsky of risk consultancy Aon, noting the cumulative effect "can ripple across supply chains and ultimately influence consumer prices."
