It is also a big week in the under-pressure oil market. The price of US oil and Brent Crude both tumbled — the latter down nearly $1 at $20 — today as storage runs short. Some oil is even being stored in small barges around Europe’s main trading hub between Amsterdam, Rotterdam and Antwerp. But shares in oil majors Shell and BP gained around 1% to 1363p and 313p respectively with both due to report on trading and, crucially, the future of their dividend payouts, this week.
