Regulation

Bank regulations are a form of government regulation which subject banks to certain requirements, restrictions and guidelines, aiming to uphold the soundness and integrity of the financial system. The combination of the instability of banks as well as their important facilitating role in the economy led to banking being thoroughly regulated. The amount of capital a bank is required to hold is a function of the amount and quality of its assets. Major banks are subject to the Basel Capital Accord promulgated by the Bank for International Settlements. In addition, banks are usually required to purchase deposit insurance to make sure smaller investors are not wiped out in the event of a bank failure.

Another reason banks are thoroughly regulated is that ultimately, no government can allow the banking system to fail. There is almost always a lender of last resort—in the event of a liquidity crisis (where short term obligations exceed short term assets) some element of government will step in to lend banks enough money to avoid bankruptcy.
