Oil prices extended losses on Wednesday as worries about global demand due to weak economic momentum in China and a likely rise in US commercial stockpiles outweighed supply fears from heightened tensions in the Middle East.
Brent futures for June fell 40 cents, or 0.44%, to $89.62 a barrel by 0632 GMT, while US crude futures for May fell 48 cents, or 0.56%, to $84.88 a barrel.
Oil prices have softened so far this week as economic headwinds pressured investor sentiment, curbing gains from geopolitical tensions, with market's eyeing on how Israel might respond to Iran's attack over the weekend.
"With oil prices highly sensitive to geopolitical risks, the past week has seen some wait-and-see consolidation in place as Israel's response will determine if there may be a wider regional conflict, which could significantly impact oil supplies," said IG market strategist Yeap Jun Rong.
"For now, the near-term weakness in oil prices may reflect some expectations that tensions may still be contained," Yeap added.
In China, the world's biggest oil importer, the economy grew faster than expected in the first quarter, but several March indicators, including property investment, retail sales and industrial output, showed that demand at home remains frail, weighing on overall momentum.
"Apart from that, a build-up in US crude inventories overnight and a mixed set of economic data out of China also offered some reservations, alongside near-term overbought technicals which prompts some profit-taking," Yeap said.
US crude oil inventories rose last week more than expected by analysts polled by Reuters, according to market sources citing American Petroleum Institute figures on Tuesday. Official data from the Energy Information Administration, the statistical arm of the US Department of Energy, is due on Wednesday at 10:30 a.m. (1430 GMT).
In the Middle East, a third meeting of Israel's war cabinet set for Tuesday to decide on a response to Iran's first-ever direct attack was put off until Wednesday, as Western allies eyed swift new sanctions against Tehran to help dissuade Israel from a major escalation.
Analysts however do not expect Iran's unprecedented missile and drone strike on Israel to prompt dramatic sanctions action on Iran's oil exports from the Biden administration.
Meanwhile, the US government could reimpose oil sanctions on Venezuela on Thursday - which in turn could tighten supplies in the market.
Prices could trade sideways in the meantime because of these current market drivers, analysts say.
WTI price movements in the short term are likely to be trapped in a sideways range between $83.20 and $87.70 due to conflicting factors such as China's disappointing retail sales in March and geopolitical risk premium still remaining intact, said OANDA senior market analyst Kelvin Wong.
