4.4.1 Role of financial markets

Financial markets are where money is saved, borrowed, exchanged and invested. They are easy to overlook, but almost every other part of the economy depends on them: firms cannot invest without finance, households cannot buy homes without mortgages, and trade cannot happen without a way to pay. This topic covers the five main roles financial markets play.

To facilitate saving

Households and firms often have money they do not need to spend now. Financial markets give them safe places to keep it and a return for doing so.

  • Banks and building societies hold deposits and pay interest.
  • Pension funds and insurance companies collect regular contributions and invest them for the long term.
  • Investment funds pool savings and invest them in shares, bonds and property.

Without these, people would have to keep their savings as cash, which earns nothing and is unsafe.

To lend to businesses and individuals

Financial markets channel the money that savers do not need to borrowers who want to spend or invest it now.

  • Firms borrow to buy machinery, build factories and fund expansion.
  • Households borrow to buy homes through mortgages, and to buy cars and other goods on credit.
  • Governments borrow by selling bonds.

Key idea: This role is central to economic growth. Banks and other lenders bring together the savings of many people and lend them to those with productive uses for them, so that investment can take place on a scale no individual saver could fund.

To facilitate the exchange of goods and services

Trade needs a reliable way to pay. Financial markets provide the payment systems that allow money to move quickly and safely between buyers and sellers:

  • debit and credit cards, bank transfers and online payments;
  • systems for transferring money between banks;
  • arrangements for paying across borders in different currencies.

Without these systems, every transaction would need cash or barter, and modern specialisation and trade would be impossible.

To provide forward markets in currencies and commodities

A forward market allows a buyer and seller to agree today on a price for a transaction that will take place in the future.

Why this matters: an example. A UK firm agrees to sell machinery to an American customer for $1 million, to be paid in six months. If the pound rises against the dollar in that time, the $1 million will be worth fewer pounds, and the firm's profit could disappear. By agreeing a forward exchange rate now, the firm locks in the number of pounds it will receive.

The same applies to commodities. A food manufacturer can agree today the price it will pay for wheat in six months, and a farmer can agree the price they will receive.

Key idea: Forward markets reduce uncertainty and protect firms against the risk of price changes. This is called hedging. It makes international trade and long-term planning easier.

To provide a market for equities

Equities are shares in companies. The stock market allows:

  • companies to raise finance by selling new shares to investors, which they can use for investment and expansion without borrowing;
  • investors to buy and sell existing shares, which makes shares easier to sell and so more attractive to hold.

In the UK, the London Stock Exchange is the main market for equities. By making it easy to buy and sell shares, it encourages people to invest in companies, which supports investment and growth.

Common mistakes

  • Listing the roles without explaining why they matter. Each role supports saving, investment, trade or growth.
  • Confusing saving with investment. Saving is income not spent; investment is spending on capital goods. Financial markets connect the two.
  • Describing forward markets as speculation. Their main role in this context is reducing risk through hedging.
  • Forgetting that firms raise finance by issuing new shares. The stock market is not only for trading existing shares.

How this has been examined

In the Edexcel papers indexed on this site, this topic has appeared in four formats:

  • 5-mark "Explain" data response — asked twice across 2 series (2019 to 2023)
  • 4-mark "Explain" data response — asked once (2022)
  • 2-mark calculation — asked once (2018)
  • 1-mark multiple choice — asked once (2024)

Where this goes next

When financial markets go wrong, the result is covered in 4.4.2 Market failure in the financial sector, and the role of the central bank in 4.4.3 Role of central banks. The link between saving and investment appears in 2.2.2 Consumption (C) and 2.2.3 Investment (I), and the currency markets themselves in 4.1.8 Exchange rates.
