The RBI mainly looks at retail inflation to frame monetary policy.
Retail inflation remained above the Reserve Bank's upper tolerance threshold of 6 per cent for the ninth month in a row and was at a 5-month high of 7.41 per cent in September, as per data released earlier this week.
To tame stubbornly high inflation, the RBI has hiked the key interest rate four times this year to 5.90 per cent -- the highest since April 2019.
