The US dollar remained elevated near a two-month high on Tuesday, supported by renewed geopolitical tensions in the Gulf region, while traders held back from major positions ahead of the closely watched US jobs report due later this week. The greenback has strengthened steadily over the past two weeks, driven by a combination of safe-haven flows and growing expectations that the Federal Reserve may keep interest rates higher for longer. The latest leg higher followed reports of increased military activity in the Gulf, which reignited concerns about energy supply disruptions and broader regional instability.
