Oil prices rose again today as OPECs monthly market eased worries about waning demand. “The OPEC monthly oil market report appeared to push back against demand concerns, referencing overblown negative sentiment around Chinese demand while raising demand growth forecasts for this year and leaving them unchanged for next,” Craig Erlam, senior market analyst at OANDA, said in a note. A US probe into Russian oil sanctions also raised concerns about potential supply disruptions. The US Treasury department sent notice to ship management companies for information on 100 vessels it suspects of violating western sanctions on Russian oil. WTI traded up $1.09 or 1.4% to close at $78.26. Brent traded up $1.09 or 1.3% to close at $82.52.
