Here is how the banker's game works:
1) Get the government to issue some currency (cash -- paper or reserves at the central bank -- reserves are government issued cash central bank deposits). Government issued cash is around 5% of the currency (money) supply. The government issued currency is put into circulation by the government simply spending it.
2) The rest (95%) of the currency is issued by the private banks. Each customer loan is a new bank deposit (i.e., new currency) and increases the currency (money) supply of the economy. Note that this newly created money (currency) is put into circulation by the borrower spending it. Most currency (about 95% America's currency supply) has been borrowed into existence and when bank customer pays the loan back that amount of currency is removed from circulation. The banking system cannot go backwards (fewer net loans) as time moves on because fewer net loans means less currency in circulation in the economy.
Accumulation of interest charges on outstanding loans means that the currency supply must constantly increase even if it means giving out lower quality loans. Think of it like a plane flying it must fly at some minimum speed or else the plane (the banking system) will crash (i.e., banking system collapse). Read more..,,,,,,,
