<h1>India's Wholesale Price Index Inflation Negative Since 2014; RBI Uses CPI-Combined for Monetary Policy Targeting.</h1> Inflation based on the Wholesale Price Index (WPI) in India has remained negative since November 2014, with a decline in inflation across various sectors such as non-food articles, minerals, crude petroleum, and basic metals. The Reserve Bank of India (RBI) has adopted the Consumer Price Index-Combined (CPI-Combined) as the primary measure for monetary policy, following an agreement on the Monetary Policy Framework with the government. This framework explicitly targets inflation as measured by the CPI-Combined. The information was provided by a government official in response to a parliamentary question.
