Tokyo: Oil prices on Friday clawed back some of its losses from the previous session, when prices fell the most in a month, as concerns about oil supply are countering worries that emerging market crises and trade disputes could dent demand. Brent crude was up 8 cents, or 0.1%, at $78.26 a barrel by 9.10am, after falling 2% on Thursday. The global benchmark rose on Wednesday to its highest since May 22 at $80.13. US West Texas Intermediate (WTI) futures were up 18 cents, or 0.2%, at 68.76 a barrel, after dropping 2.5% on Thursday. Brent is heading for a 1.8% gain this week, while WTI is on track for a 1.5% increase.
