Relationship between lenders and borrowers

Lenders

 Individuals

Many individuals are not aware that they are lenders, but almost everybody does lend money in many ways. A person lends money when he or she:
• puts money in a savings account at a bank; 
• contributes to a pension plan; 
• pays premiums to an insurance company; 
• invests in government bonds; or 

• invests in company shares. 

Companies

Companies tend to be borrowers of capital. When companies have surplus cash that is not needed for a short period of time, they may seek to make money from their cash surplus by lending it via short term markets called money markets.
There are a few companies that have very strong cash flows. These companies tend to be lenders rather than borrowers. Such companies may decide to return cash to lenders (e.g. via a share buyback.) Alternatively, they may seek to make more money on their cash by lending it (e.g. investing in bonds and stocks.)
 Borrowers
Individuals borrow money via bankers' loans for short term needs or longer term mortgages to help finance a house purchase.
Companies borrow money to aid short term or long term cash flows. They also borrow to fund modernisation or future business expansion.
Governments often find their spending requirements exceed their tax revenues. To make up this difference, they need to borrow. Governments also borrow on behalf of nationalised industries, municipalities, local authorities and other public sector bodies. In the UK, the total borrowing requirement is often referred to as the Public sector net cash requirement (PSNCR).
Governments borrow by issuing bonds. In the UK, the government also borrows from individuals by offering bank accounts and Premium Bonds. Government debt seems to be permanent. Indeed the debt seemingly expands rather than being paid off. One strategy used by governments to reduce the value of the debt is to influence inflation.
Municipalities and local authorities may borrow in their own name as well as receiving funding from national governments. In the UK, this would cover an authority like Hampshire County Council.
Public Corporations typically include nationalised industries. These may include the postal services, railway companies and utility companies.
Many borrowers have difficulty raising money locally. They need to borrow internationally with the aid of Foreign exchange markets.
