‘Rogue broker’ blamed for oil spike

The startling spike in oil prices to their highest level this year on Tuesday was caused by a rogue broker who placed a massive bet in the Brent oil market, triggering almost $10m (€7m) of losses for his company.

Prices rose in one hour from $71 to $73.5, the highest level for the year, according to Reuters data. In total, futures contracts for more than 16m barrels of oil changed hands in that hour – equivalent to double the daily production of Saudi Arabia, the world’s largest oil producer, and far more than the traditional 500,000 barrels for that time of the day.
