The Reserve Bank of India was established following the Reserve Bank of India Act of 1934. Though privately owned initially, it was nationalized in 1949 and since then fully owned by Government of India. The Reserve Bank of India was founded on 1 April 1935 to respond to economic troubles after the First World War. The Reserve Bank of India was conceptualized based on the guidelines presented by the Central Legislative Assembly which passed these guidelines as the RBI Act 1934. RBI was conceptualized as per the guidelines, working style and outlook presented by Dr. B. R. Ambedkar in his book titled “The Problem of the Rupee – Its origin and its solution” and presented to the Hilton Young Commission. The bank was set up based on the recommendations of the 1926 Royal Commission on Indian Currency and Finance, also known as the Hilton–Young Commission. The original choice for the seal of RBI was the East India Company Double Mohur, with the sketch of the Lion and Palm Tree. However, it was decided to replace the lion with the tiger, the national animal of India. The Preamble of the RBI describes its basic functions to regulate the issue of bank notes, keep reserves to secure monetary stability in India, and generally to operate the currency and credit system in the best interests of the country. The Central Office of the RBI was established in Calcutta (now Kolkata) but was moved to Bombay (now Mumbai) in 1937. The administration nationalized commercial banks and established, based on the Banking Companies Act, 1949 (later called the Banking Regulation Act), a central bank regulation as part of the RBI. Furthermore, the central bank was ordered to support economic plan with loans. The national economy contracted in July 1991 as the Indian rupee was devalued. The currency lost 18% of its value relative to the US dollar, and the Narsimha Committee advised restructuring the financial sector by a temporal reduced reserve ratio as well as the statutory liquidity ratio. New guidelines were published in 1993 to establish a private banking sector. This turning point was meant to reinforce the market and was often called neo- liberal. The central bank deregulated bank interests and some sectors of the financial market like the trust and property markets. This first phase was a success and the central government forced a diversity liberalization to diversify owner structures in 1998.
