What if an Iran-backed Shia uprising erupts in Bahrain?
An Iran-backed Shia uprising in Bahrain threatens the US Fifth Fleet and, by proximity, Hormuz/Saudi Eastern Province -- so the +3.6% Brent is really a Hormuz-spillover premium, not Bahrain's own (negligible) output. Rhymes with the 2011 Bahrain uprising, crushed by the Saudi-led GCC Peninsula Shield intervention, which kept oil calm. Transmission: Bahrain is a Saudi client (causeway, bailouts) and US naval hub; the genuine risk is Saudi/Iranian escalation. Forward: any sign of a 2011-style Saudi intervention caps the premium quickly.

What it would mean
