With Islamist militants claiming large parts of Iraq at alarming speed, the price of Brent crude has risen above $114 for the first in nine months. Currency experts now warn that there will be winners and losers in the foreign exchange markets on the back this oil spike.

Neil Mellor, a senior currency strategist at BNY Mellon, believes there will be a divergence between certain currencies in the coming weeks if investors remain nervous over Iraq. This divide will be based on countries' ability to pay their debts and their dependency on energy imports, he said.
