SCB EIC expects global oil prices to soften in 2027 as non-OPEC supply grows faster than demand, though geopolitical risk keeps prices volatile. Thai retail fuel prices may fall more slowly than world crude because the oil fund still carries heavy debt, and diesel is expected to stay flat rather than drop quickly. For SMEs relying on trucking or fleet fuel, do not bank on a sharp cost drop in 2027 when setting prices or budgets. Petrochemical plastics (PE, PP) face continued oversupply, so commodity plastic users may see competitive pricing pressure. Fuel station operators should plan for thinner fuel margins and push non-oil and convenience income.
