Talk Royal Dutch Shell is looking at buying Canadian oil/gas co Encana is also being given as part reason for the fairly sharp sell-off in cable this morning. I guess the confusion comes from the fact company head quartered in the Hague, Netherlands, but incorporated in the UK.
Anyways, both EUR/USD and GBP/USD seem to be steadying after their early swoons, presently at 1.3140 and 1.5840 respectively.
