SINGAPORE, Oct 30 (Reuters) - High oil prices are hurting consumers and could also have adverse implications for producers, the executive director of the International Energy Agency (IEA) said on Tuesday.

Major emerging Asian economies such as India and Indonesia have been hit hard this year by rising crude oil prices LCOc1 , which despite falls this month are up by around 15 percent since the start of 2018.

Fuel import costs have been pushed up further by a slide in emerging market currencies against the dollar .DXY , denting growth and even triggering protests and government fuel price controls in India.

"Many countries' current account deficits have been affected by high oil prices," IEA chief Fatih Birol said at an energy conference in Singapore.

"There are two downward pressures on global oil demand growth. One is high oil prices, and in many countries they're directly related to consumer prices. The second one is global economic growth momentum slowing down."
