US crude prices rallied sharply in thin weekend trading, climbing between 5.5% and 8.0% on IG Group’s out-of-hours platform early Sunday in Asia, according to price snapshots posted around 02:40 a.m. GMT. The move adds to the commodity’s recent volatility and offers an early indication of sentiment ahead of the reopening of mainstream futures markets on Monday. While oil advanced, IG’s weekend contracts tracking major equity indices edged 1.23% lower, suggesting a cautious tone for risk assets at the start of the new week. Weekend markets are typically less liquid than regular sessions, but the magnitude of the jump in crude underscores traders’ watchfulness for supply headlines that could tighten the market when full trading resumes.
