"Certainly, 4.7% for the month is better than we had expected. I think it does indicate that there is distinct downturn on inflation which is welcome," Ahluwalia told reporters.
The Wholesale Price Index-based on inflation fell to 4.7% in May, driven mainly by decline in prices of manufactured items, even as prices of food articles inched up.

Inflation based on the Wholesale Price Index (WPI) stood at 4.89% in April. In May, 2012, it was 7.55%.
Asked whether RBI should consider the easing of inflation in its mid-quarter review next week, he said, "They should certainly consider it because it is very clear that the underline inflationary pressure is softening."
The industrial output in April showed a very modest growth of 2.3%, down from 3.4% in March.
According to Ahluwalia, food inflation in the longer period is also coming down. Inflation in food articles category, which has a 14.34% share in the WPI basket, rose to 8.25% in May. Inflation in this category was at 6.08% in April.
"If you look at the components of inflation, the food prices increase has slightly gone up. This is the base level effect I was referring to earlier," Ahluwalia explained.
"Inflation is softening. I think the number is lower than it was last year. The good news is that the non-food inflation has really gone down much more than you thought it would. I think the base level effect will wear out in the years ahead," he added.
The non-food articles category, which include fibre, oil seeds and minerals, saw sharp decline in inflation to 4.88% in May from 7.59% in April.
