What are financial derivatives?

Beyond investing in shares, bonds or funds, there are more sophisticated financial tools that allow investors to adapt to changing environments, protect themselves against risk or even profit from market moves without owning the assets directly. This is where FINANCIAL DERIVATIVES come in.

Financial derivatives belong to this group of instruments. Although they may seem complex, their logic is clear: they are contracts whose value depends on the behaviour of another asset. In this article we explain what they are, what they are used for and the most common types.

What is a financial derivative?

A financial derivative is a contract whose value is based on the price of an underlying asset. That asset can be a share, a bond, a commodity, an interest rate, a stock market index or a currency.

The derivative therefore has no value of its own; its price is derived from that underlying asset. The parties to the contract agree to buy or sell the asset in the future, or to exchange cash flows depending on how its price evolves.

What are derivatives used for?

Financial derivatives can serve different purposes, and how they are used depends on the investor's profile:

• Hedging: they allow you to protect a portfolio against potential falls or adverse price movements.
• Speculation: seeking profits by betting on future market moves.
• Leverage: they provide exposure with less initial capital, amplifying both gains and losses.
• Arbitrage: they are used to exploit price inefficiencies between markets.

📌 Practical example:
An airline can use derivatives to lock in the price of fuel. That way it avoids a spike in crude oil prices sending its operating costs through the roof.

Where are derivatives traded?

Derivatives can be traded on organised markets or directly between the parties:

– ETD (Exchange-Traded Derivatives)

These are standardised contracts, such as futures and options, traded on regulated exchanges. In Spain, for example, there is the MEFF (Mercado Español de Futuros Financieros, the Spanish financial futures exchange).

– OTC (Over the Counter)

These are bilateral agreements, tailor-made between the parties. While they offer greater flexibility, they involve more counterparty risk and less transparency.

Main types of financial derivatives

1. Futures and forwards

Both are contracts to buy or sell an asset on a future date at a price agreed today.

• Futures: standardised and traded on an exchange.
• Forwards: customised contracts between parties, traded off-exchange.

🎯 Example:
A farmer sells wheat futures to lock in a price before the harvest, preventing a fall in prices from ruining the season.

2. Options and warrants

They give the buyer the right (but not the obligation) to buy or sell an asset in the future.

• Call (buy option): allows you to buy.
• Put (sell option): allows you to sell.

The buyer pays a premium for this right. Losses are limited to that premium, while the potential upside is wide.

Warrants work in a similar way, but they are usually issued by banks or financial institutions and offer more flexibility in their design.

3. CFDs (Contracts for Difference)

They allow you to speculate on changes in an asset's price without owning it. The gain or loss is calculated as the difference between the entry price and the exit price.

They are widely used by short-term traders, but they carry high risk, especially when leverage is involved.

4. Swaps

These are agreements between two parties to exchange future cash flows.

The most common are:

• Interest rate swaps: fixed payments are exchanged for variable ones.
• Currency swaps: cash flows in different currencies are exchanged to hedge exchange rate risk.
• Commodity swaps: based on commodity prices such as oil or gas.

This type of derivative is common among companies and banks looking to adjust their financial exposure.

Main risks of derivatives

Although they offer many advantages, derivatives also involve significant risks if used without proper management:

• Leverage risk: you can lose more than you invested if the market moves against you.
• Market risk: the price of the underlying asset can be highly volatile.
• Counterparty risk: in OTC transactions, one of the parties may fail to honour its commitment.
• Liquidity risk: some derivatives can be hard to sell or value if there is not enough of a market.

Conclusion

Financial derivatives are advanced tools that can be very useful for protecting portfolios, diversifying risk or enhancing the return on an investment. But they can also become a trap if used without knowledge or control.

If you are thinking about using them, it is essential to understand exactly how they work, know your objectives and have the right professional advice.
