London pre-open: Stocks seen lower as US imposes sanctions on Iran

The FTSE 100 was called to open 26 points lower at 7,390.

David Madden, market analyst at CMC Markets, said: "Tensions between the US and Iran have ticked up after President Trump singed an executive order imposing ‘hard-hitting’ sanctions on Iran as a retaliation for downing a US drone.

"Washington DC claimed the US will maintain its tough stance against the regime until it halts its ‘dangerous activities’. The US leader balanced out the statement by saying he doesn’t ‘seek conflict with Iran’. Tehran claimed that diplomatic relationships could be closed ‘forever’ but that sounds like bluster.

"The rising tensions actually played a role in the sell-off in the oil market as traders began to fear that "demand for oil will fall. The G20 summit is likely to play a big role in oil’s next move as a fractured trading relationship between the US and China has added to fears that oil demand will decline in the medium-term."
