⚖
The Guardian frames Trump's Iran deal as unclear and self-serving, emphasizing market reactions while questioning the agreement's substance and Trump's role in creating the original problem.

Trump reasserts US negotiating leverage by reopening critical waterway; Iran gains military reprieve but faces unclear concessions; Israel's regional dominance questioned by ceasefire scope; global energy markets shift from supply-shock concerns to potential normalization.
Similar to 2015 JCPOA negotiations—optimistic market signals preceded by vague terms and last-minute complications; risk of deal collapse if Friday signing fails.

Lower oil prices could reduce fuel and energy costs for households, but uncertainty about deal durability creates volatility risk. Consumers benefit from reduced geopolitical premium in energy prices if deal holds.
