In the same release, the Domestic Supply Price Index was unchanged on the month but up 11.7% on the year, and the Total Output Price Index rose 1.2% on the month and 16.7% on the year. Within the Producer Price Index, manufacturing prices increased 0.7% on the month and 13.3% on the year, while services rose 1.2% on the month and 4.9% on the year. Agricultural, forestry and marine products fell 0.8% on the month, although they were still 4.8% higher than a year earlier. The flat monthly reading in the Domestic Supply Price Index reflected an 8.1% drop in raw materials prices offset by a 1.2% rise in intermediate goods and services and a 0.3% increase in final goods and services. The Total Output Price Index was lifted mainly by a 1.4% monthly rise in manufacturing product prices, while agricultural, forestry and marine products edged down 0.4%.
