Hiking interest rates by the RBI aims to control inflation by encouraging deposits, discouraging borrowing, and reducing money supply in the economy.
"RBI governor will say okay we have decided to hike up interest rates. Now when you hike up interest rates those who deposit money in the bank will earn more. Those who borrow money will pay more. So more people deposit less people borrow money which was floating in the economy goes into the banking sector when money supply in the economy comes down inflation comes down"
