Financial Markets and Assets

In earlier modules, we observed that individuals can either consume or save their income. We also noted that business investment in physical capital is the primary way they grow. Where do individuals put their savings, and where do businesses obtain the funding for investment expenditure? The answer to both of these questions is financial markets.

United States' households and businesses saved almost $2.9 trillion in 2012. Where did that savings go and what was it used for? Some of the savings ended up in banks, which in turn loaned the money to individuals or businesses that wanted to borrow money. Some was invested in private companies or loaned to government agencies that wanted to borrow money to raise funds for purposes like building roads or mass transit. Some firms reinvested their savings in their own businesses.

Financial markets include the banking system, equity markets like the New York Stock Exchange, or the NASDAQ Stock Market, bond markets, commodity markets and more. In the 21st Century, financial markets are global, Americans put their savings into foreign as well as domestic bank accounts, foreign and domestic stocks and foreign and domestic bonds. All financial assets are called securities. Equities (i.e. stocks) give savers ownership in a company in return for dividends (a regular payment from the company) and/or capital gains (e.g. when you sell the stock at a profit). Bonds are a type of debt. All forms of debt are IOUs, where a saver lends money to a borrower in return for an interest payment.
