Global oil prices fell in early Tuesday morning trading in Asia.
Brent was down by about 8.5% at $92.50 (£68.85) a barrel. US-traded oil also fell around 9%, to $88.60 a barrel.
The drop follows US President Donald Trump’s remarks on Monday that the war will be over “very soon”.
The prices are still about 30% higher than they were at the start of the conflict.
Asian markets appear to have been given a boost by the dip in oil prices in early trade. Japan’s Nikkei 225 index was up by 2.8% and South Korea’s Kospi exchange rose by more than 5%.
Indexes in Asia were dealt a heavy blow by the surge oil prices as many countries in the region are big customers of the Gulf states.
