"The market could be pinning too much hope on the US-China talks yielding some positive results on Iran," ING Bank said in a note. "Some hope that China could exert pressure on Iran to reach a deal with the US, to end the war and lead to a resumption of energy flows through the Strait of Hormuz."

"Inflation pressures are mounting due to the Iran conflict and could take a larger toll on overall spending."
