Singapore’s domestic supply price index surged by 38.8% year-on-year in August 2026, marking the fastest rise on record and accelerating from an upwardly revised 33.6% gain in the previous month. The increase was driven mainly by higher prices for mineral fuels, lubricants and related materials (57.4% vs 46.8% in July), machinery and transport equipment (47.7% vs 42.3%), and chemicals and chemical products (13.8% vs 11.3%). Costs also rose faster for crude materials (20.2% vs 19.4%) and beverages and tobacco (4.5% vs 4.0%). Meanwhile, the non-oil domestic supply price index climbed to 33.0% from 29.3%. In contrast, food and live animals fell 1.4%, slightly deeper than the 1.2% decline in July. Producer inflation also softened for manufactured goods (4.9% vs 5.0%) and animal and vegetable oils, fats and waxes (4.2% vs 4.9%). On a monthly basis, the domestic supply price index rose by 4.1% in August, following an upwardly revised 2.4% gain in the preceding period.
