US crude just dropped below $90/barrel as Trump keeps teasing a deal with Iran. Markets hate uncertainty but they love cheaper energy, so every signal that sanctions might ease gets priced in immediately. This is the inverse of his first admin's "maximum pressure" campaign. If he actually follows through on a deal, it fundamentally reshapes energy markets and geopolitics. If he's just flogging a carrot to look tough, crude could bounce right back. Either way, the fact that oil is already repricing on speculation shows how much Trump's words move capital.
