Final answer:
Individuals and businesses supplying financial capital through savings or investments are the ones who supply money to the financial markets.
Step-by-step explanation:
In the financial markets, entities that supply money are typically the ones who save or make financial investments, including both individuals and businesses. These suppliers of financial capital receive a rate of return on their investments, which may come in the form of interest payments, dividends, or capital gains. Banks are a common example of financial intermediaries, which help to coordinate the supply and demand of financial capital. Investors who accept more risk or less liquidity generally expect a higher rate of return.
