ISLAMABAD, Jan 2: The weekly inflation has decelerated from a three decade high in October after a substantial decrease in domestic oil prices in the wake of slump in international oil prices.

The inflation measured through Sensitive Price Index (SPI) eased to 21.08 per cent for the week ended on January 1, from 34 per cent in September 2008, the highest-ever, the Federal Bureau of Statistics data revealed here on Friday.

The downward trend in the weekly inflation showed some let-up in fruits, rice, ghee/oil, vegetable and flour prices in the past few weeks. The SPI recorded a decline of 0.58 per cent during the week under review over the previous week.

Analysts said that the inflation could have eased much more provided the government revised downward the oil prices, which were kept unchanged for the past one month.

The government also misled the National Assembly by increasing the gas tariff by 17 per cent. In the last session it had assured the lower house of not making any increase in the gas tariff.

A source said that the government had earned more than Rs20 billion for not passing the actual decrease in oil prices to consumers during the past one month. The earning would reach a double figures in the current fortnight ending January 15.

The SPI witnessed an increase of 20.52 per cent and 21 per cent for households in income brackets of up to Rs3, 000 and Rs3, 001 to Rs5,000, respectively. For households in the income brackets of Rs5,001 to 12,000, the increase was in the range of 21.81 per cent, and for households in the income basket of over Rs12,000 inflation registered a growth of 21.03 per cent over the same week last year.
