Money creation is the process by which the money supply of a country or a monetary region (such as the Eurozone) is increased. A central bank may introduce new money into the economy (termed "expansionary monetary policy", or "money printing" by detractors) by purchasing financial assets or lending money to financial institutions. Commercial bank lending also creates money under the form of demand deposits. When banks have reserve requirements (freezing a percentage of their deposits in mandatory reserves at the central bank) the process multiplies this base money through fractional reserve banking. Central banks monitor the amount of money in the economy by measuring monetary aggregates such as M2. The effect of monetary policy on the money supply is indicated by comparing these measurements on various dates. For example, in the United States, money supply measured as M2 grew from $6.407 trillion in January 2005, to $8.319 trillion in January 2009.〔(US Federal Reserve historical statistics ) June 11, 2009〕 ==Money creation by the commercial banks== (詳細はasset and the deposit a liability on the bank's balance sheet. 〔"In the modern economy, most money takes the form of bank deposits. But how those bank deposits are created is often misunderstood: the principal way is through commercial banks making loans. Whenever a bank makes a loan, it simultaneously creates a matching deposit in the borrower’s bank account, thereby creating new money." Michael McLeay et al, Quarterly Bulletin 2013 Q1, http://www.bankofengland.co.uk/publications/Documents/quarterlybulletin/2014/qb14q102.pdf〕 Monetary policy regulates a country's money supply, the amount of broad currency in circulation. Almost all modern nations have central banks such as the United States Federal Reserve System, the European Central Bank (ECB), and the People's Bank of China for conducting monetary policy. Charged with the smooth functioning of the money supply and financial markets, these institutions are generally independent of the government executive. The primary tool of monetary policy is open market operations: the central bank buys and sells financial assets such as treasury bills, government bonds, or foreign currencies from private parties. Purchases of these assets result in currency entering market circulation, while sales of these assets remove currency. Usually, open market operations are designed to target a specific short-term interest rate. For example, the U.S. Federal Reserve may target the federal funds rate, the rate at which member banks lend to one another overnight. In other instances, they might instead target a specific exchange rate relative to some foreign currency, the price of gold, or indices such as the consumer price index. Other monetary policy tools to expand the money supply include decreasing interest rates by fiat; increasing the monetary base; and decreasing reserve requirements. Some other means are: discount window lending (as lender of last resort); moral suasion (cajoling the behavior of certain market players); and "open mouth operations" (publicly asserting future monetary policy). The conduct and effects of monetary policy and the regulation of the banking system are of central concern to monetary economics. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「money creation」の詳細全文を読む スポンサード リンク
