Oil -7% Crushes UK Energy Majors — Shell -1.4%, BP -1.1%
Brent crude fell roughly 7% on Iran deal optimism, per FT and multiple outlets. Shell closed at $85.71 (-1.40%) and BP at $44.36 (-1.14%). For FTSE 100 passive investors, Energy represents ~10% of index weight, making oil-driven moves structurally important to UK total returns. The read for Tuesday: if Iran talks stall, Shell and BP get a mechanical bounce; if they progress, a second leg down tests UK energy stocks' 200-day averages. Shell's downstream refining margins are a partial natural hedge — watch for any management commentary at their upcoming Capital Markets Day.
