US President Donald Trump's promise of "good" and "productive" talks with Iran are perhaps his most conciliatory remarks since the beginning of Operation Epic Fury, but leave significant unanswered questions. Early on Monday morning - just hours before markets opened - Trump took to Truth Social, promising to hold off on striking Iranian power plants and energy infrastructure for a five-day period as talks continue, after having previously threatened to "obliterate" these targets unless Iran opens the Strait of Hormuz. Iran, however, has denied that any contact between its official and the Trump administration has taken place.
