Following the Great Depression of 1930s, many bank regulations came into effect. Regulation Q (1933), Glass-Steagall (1933 & 1935) and McFadden Act (1927) act are few regulations that came into effect in US as a result of the crisis. However, these bank regulations failed to control the growth of number of banks leading to overcapacity. This overgrowth imposed risk to the financial stability. With no cap on interest rates for savings deposits, banks lured customers with higher interests for deposits. To prevent another financial disaster, few steps were taken in the US banking sector in 1980s. Between 1978 and 1986, Regulation Q was repealed in phases. This act repeal enforced ceiling on interest rate for savings deposits. This imposed cap on savings deposit interest rates also encouraged customers to find other options to banks. Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 abolished all prohibitions on interstate banking. This enabled banking between states and movement of money in diversified way.These relaxed laws allowed the emergence of alternatives to banks such as mutual funds etc.., and merger of banks soon took place. Due to large economies of scale and economies of scope, bigger banks provide increased financial stability. As
