6. Investment banking/Central banking (Инвестиционная деятельность банков/ Деятельность центробанка)

Investment banking is a specific division of banking related to the creation of capital for other companies, governments and other entities. Investment banks underwrite new debt and equity securities for all types of corporations, aid in the sale of securities, and help to facilitate mergers and acquisitions, reorganizations and broker trades for both institutions and private investors. Investment banks also provide guidance to issuers regarding the issue and placement of stock.

The top investment banks are Goldman Sachs, JP Morgan and Morgan Stanley.

The two main lines of business in investment banking are called the sell side and the buy side. The "sell side" involves trading securities for cash or for other securities (e.g. facilitating transactions, market-making), or the promotion of securities (e.g. underwriting, research, etc.). The "buy side" involves the provision of advice to institutions concerned with buying investment services. Private equity funds, mutual funds, life insurance companies, unit trusts, and hedge funds are the most common types of buy side entities.

An investment bank can also be split into private and public functions with an information barrier which separates the two to prevent information from crossing. The private areas of the bank deal with private insider information that may not be publicly disclosed, while the public areas such as stock analysis deal with public information.

Central banking

A central bank, reserve bank, or monetary authority is an institution that manages a state's currency, money supply, and interest rates. Central banks also usually oversee the commercial banking system of their respective countries. In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base in the state, and usually also prints the national currency, which usually serves as the state's legal tender.

The primary function of a central bank is to control the nation's money supply (monetary policy), through active duties such as managing interest rates, setting the reserve requirement, and acting as a lender of last resort to the banking sector during times of bank insolvency or financial crisis. Central banks usually also have supervisory powers, intended to prevent bank runs and to reduce the risk that commercial banks and other financial institutions engage in reckless or fraudulent behavior. Central banks in most developed nations are institutionally designed to be independent from political interference. Still, limited control by the executive and legislative bodies usually exists.
