"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 all-powerful Monetary Policy Committee headed by Urjit Patel, Rajan's successor at RBI, last week cut benchmark interest rates by 0.25 per cent to 6.25 per cent.
While he had signaled more tolerance for price pressure, the easing in CPI inflation rate was in line with the RBI's forecast for average 5 per cent inflation in fourth quarter of 2016. This, many expect, would create more room for interest rate reduction.
The next monetary policy review is scheduled for December 7.
