The week on week acceleration in WPI index hint for the underlined inflationary pressure. The rising food prices and lower rainfall generates uncertainty for food prices. The WPI recorded 1.74% fall for the week ended 1 August 2009, which moved up to 0.95% decline for week ended 15 August 2009. The 0.6% growth in WPI for week ended 22 August 2009 signals that inflation is hovering at the edge of positive territory.
