Domestic supply prices fall 1.9% in May

Lower petroleum prices offset continued increases in non-oil goods.

Domestic Supply Price Index fell 1.9% MoM in May 2026 to 130.9, reversing the 3.4% increase recorded in April.

The decline was mainly driven by a 9.3% fall in the oil index due to lower petroleum and related product prices. Petroleum prices dropped 10.3% from the previous month.

Meanwhile, the non-oil index rose 1.6% to 127.9, extending the 5.4% increase recorded in April.

The increase was led by machinery and transport equipment, which climbed 3.1% amid higher prices of electrical machinery, apparatus and parts.

Prices of animal and vegetable oils rose 2.1%, whilst crude materials increased 1.4% and beverages and tobacco gained 1%.

These increases were partly offset by a 2.7% decline in chemicals and chemical products and a 0.2% fall in food and live animals.

Compared with May 2025, the overall Domestic Supply Price Index surged 34.2%, accelerating from the 32.1% increase in April.

The oil index rose 77.2% YoY, whilst the non-oil index increased 21.8%.

Year-on-year non-oil growth was driven mainly by machinery and transport equipment, which rose 27.6%, including a 37.9% increase in electrical machinery and parts. Chemicals and chemical products climbed 21.5%, whilst food and live animals fell 2.6%.
