Why a financial system exists
Some economic agents have surplus cash while others need funding. Finance connects the two.
Capital can flow directly through securities markets or indirectly through financial intermediaries such as banks and funds.
The system performs four core functions: funding, payments, risk transfer and price discovery.
A market price is not simply a fact about value; it is the clearing result of supply, demand, expectations, information, liquidity and constraints.
Imagine a company wants to build a factory but does not have enough cash today. At the same time, households, pension funds and other investors have savings they want to put to work. The financial system creates the channels that allow those savings to fund productive activity. In return, investors receive a financial claim such as a bond or a share.
A household deposits $10,000 at a bank. The bank can use its funding base to make loans. Alternatively, that household can buy a corporate bond, funding the company through the capital market.
When confidence, liquidity or funding conditions deteriorate, this transmission mechanism can weaken. That is why central-bank liquidity, bank capital and market functioning matter during stress.
Directing funds toward different uses or investments.
The process through which trading reveals a market-clearing price.
An institution that connects providers and users of capital.
