Oil falls more than $4 as US, Iran remain at odds over peace deal

Global crude oil futures plunged over $4 a barrel on Monday as the elusive US-Iran "peace deal" remained firmly off the table, with diplomatic efforts stalling amidst escalating rhetoric. The market's sharp downturn reflects growing fears that persistent animosity between Washington and Tehran will continue to jeopardize oil transit through the critical Strait of Hormuz, maintaining a tight supply outlook. This latest dip underscores the fragility of energy markets, which had priced in a slim chance of a diplomatic breakthrough that would ease sanctions on Iran and potentially unlock significant oil supplies. The Biden administration's refusal to lift key sanctions without verifiable steps on Iran nuclear program, coupled with Tehran's insistence on full economic reintegration, has created an intractable impasse. The ongoing deadlock exacerbates geopolitical risk in the Middle East, a region vital for over a fifth of the world's oil supply, at a time when global demand remains robust and OPEC+ holds firm on current production quotas. As the prospects of a swift resolution fade, energy traders and policymakers will be closely monitoring any naval movements in the Persian Gulf and statements from both capitals. The immediate ripple effect will be continued volatility in crude oil futures and increased inflationary pressures. Businesses should brace for sustained higher energy costs, impacting everything from supply chains to consumer spending, potentially dampening global economic growth for the latter half of 2026.
