Oil prices sank around 1.5% on Thursday, continuing a fall from the prior day and touching their lowest in over a month, on lingering worries that aggressive US interest rate hikes could trigger a recession and dent fuel demand. Meantime, the US EIA said its weekly oil data, which was scheduled for release later today, will be delayed until at least next week. WTI oil traded around $104 a barrel while Brent crude at $110.
