Oil prices moved higher on Monday as traders continued to weigh whether OPEC+ members will keep supply tight enough to support the market. Brent crude futures gained 0.6% to $78.45 a barrel, reflecting cautious buying after weeks of concern over production discipline.

The latest move came as global inventories remain relatively constrained, leaving the market sensitive to any signs of weaker output restraint from major producers. Even modest changes in supply expectations can quickly shift prices when stockpiles are not comfortably high.

Analysts say the market is being driven less by fresh demand data and more by uncertainty around how closely producers will stick to agreed cuts. For now, that uncertainty is helping keep crude prices elevated, even as broader economic signals remain mixed.

Energy markets are likely to stay volatile in the near term, with traders watching both OPEC+ policy signals and inventory trends for clues about the next move in prices.
