Two opposing forces converge on the near-term Brent ceiling: de-escalatory US-Iran talks push oil risk premia down, while Russian militarization of Baltic shadow-fleet tankers pushes them up.
// Cascade Logic
US-Iran negotiations → lower Gulf risk premium → higher chance Brent stays below $85; Russian armed tanker escort → sanctions-enforcement flashpoint and supply-route risk → upward pressure that erodes that ceiling. Net effect determines whether Brent clears $85.
