Crude oil futures edged lower in mid-morning trade in Asia Tuesday amid supply uncertainty in the lead-up to the G20 summit and OPEC meetings over the next fortnight.  At 11:05 am Singapore time (0305 GMT), ICE January Brent crude futures were down 22 cents/b (0.36%) from Monday’s settle at $60.26/b, while the NYMEX January light sweet crude contract was 30 cents/b (0.58%) lower at $51.33/b. Market watchers were looking to this weekend’s G20 summit, where the trade dispute between the US and China will be discussed, and to the OPEC meeting on December 6, where output policy talks with key non-OPEC producers including Russia will be the focus, for further cues on supply.  Oversupply concerns stemmed from record high production by key producer Saudi Arabia, analysts said. “While commentary from Saudi Arabia suggests it is willing to cut output to stabilize prices, the data continues to show them producing at record levels,” ANZ analysts said Tuesday, citing reports that the kingdom’s output has reached 11.2 million b/d, up from 10.8 million b/d earlier this month.  Cautious sentiment ahead of the G20 summit has capped the recent rebound, analysts said. “Stabilizing oil prices also added on to the risk-on environment with Brent rebounding to above $60 [Monday],” Mizuho Bank’s head of economics and strategy Vishnu Varathan said Tuesday.  “Nonetheless, the durability of the rebound is set to be tested as Trump has resumed his confrontational approach ahead of G20 meeting with Xi,” Varathan added.  Meanwhile, the US oil and natural gas rig count rose by eight to 1,208 for the week ended November 21, the highest since March 2015, latest data by S&P Global Platts Analytics showed Monday. The oil rig count rose by 13 to 960, countering a decline in gas-oriented rigs, the data showed.
