#XAU/USD# #commodities: #oilprices gained on Friday in anticipation of 20% lower Russian crude exports from the Baltic region in December, offsetting worries of lower fuel demand due to the looming Arctic storm across the U.S this holiday season. Brent crude and U.S WTI crude traded more than 1% higher at $81.86 and $78.41 per barrel. Amid further demand concerns, China is still the market’s biggest wildcard to reverse the course.
