Although services account for around 60 per cent of the country's economy, they are neither captured fully by the Wholesale Price Index (WPI) based inflation nor the Consumer Price Index (CPI), which reflects the rate of price rise at retail level.
The standing Committee on Finance, headed by Congress leader Veerappa Moily, has said that accurate data on services inflation is crucial for understanding relative price movements as also inter-sectoral terms of trade.
The panel said that sectoral regulators need better data on prices, production and quality of services to act in the consumer interest.
"Accurate data on services inflation is crucial for understanding relative price movements, particularly since the services sector accounts for over half the GDP," it said in its report tabled in Parliament on Friday.

"The Committee would, therefore, recommend a separate and distinct index namely, Business Service Price Index, which will accurately factor in and reflect the rising costs of different services in the economy, enabling the government to tailor their policy responses accordingly," it added.
However, the rising cost of education, healthcare, entertainment and transportation do not get fully reflected even in CPI, it added.
As per government data, retail inflation rose 3.65 per cent in February, year-on-year, as food inflation quickened. The rates at the wholesale level also soared to 39-month high of 6.55 per cent.
