"Why has since Rexit Consumer Price Index declined and interest rates too? R3 and his cheer choir a hoaz, or pushing an anti Indian agenda?," he tweeted.
While Rexit refers to exit of Rajan, he uses R3 to describe Raghuram Rajan. Swamy had virtually carried out a campaign against Rajan calling his inflation-centric policies anti-growth.
Consumer prices inflation slowed to 4.31 per cent in September from 5.05 per cent in August.

The next monetary policy review is scheduled for December 7.
