What is Swap Trading? What Does It Mean to Buy Swaps? How Did Investors Profit from Swaps in 2008?

Swap trading is one of the most complex yet crucial financial instruments. Swaps are used for risk management, speculation, and arbitrage across various financial assets. However, the general public became widely aware of them in 2008 when credit default swaps (CDS) played a central role in the global financial crisis.

In this article, we will explain what swaps are, how they work, why investors buy them, and how financial institutions made billions of dollars using them during the 2008 crisis.

What is a Swap?

A swap is a derivative financial instrument, which is an agreement between two parties to exchange cash flows based on specific financial conditions in the future.

Swaps are used for various purposes:

• Managing interest rate risks.
• Hedging currency risks.
• Speculating on market conditions.
• Protecting against borrower default.

In simple terms, a swap is a contract where two parties agree to exchange payments based on predetermined conditions.

Types of Swaps

1. Interest Rate Swaps (IRS)

✔ One party receives a fixed interest rate, while the other receives a floating rate.
✔ Used to manage exposure to changing interest rates.
✔ Most commonly used by banks and corporations.

Example:
A company takes out a loan with a floating interest rate but fears that rates may rise. It enters into an interest rate swap with a bank, where it agrees to pay a fixed interest rate instead, reducing its exposure to interest rate fluctuations.

2. Currency Swaps

✔ Allow two parties to exchange payments in different currencies.
✔ Used to hedge against currency risks.
✔ Commonly used by multinational corporations.

Example:
A U.S. company wants to take a loan in euros, but interest rates in Europe are high. Instead, it borrows in U.S. dollars at a lower rate and then enters into a currency swap to convert its payments into euros at a favorable rate.

3. Credit Default Swaps (CDS)

✔ Used as insurance against a borrower's default.
✔ Essentially, a financial insurance policy for corporate or government debt.
✔ These swaps played a central role in the 2008 financial crisis.

Example:
A bank holds bonds from Company A but is worried about potential default. It buys a CDS contract from another financial institution (such as AIG), which guarantees compensation if Company A defaults.

If Company A goes bankrupt, the bank receives a payout from the CDS provider.

What Does It Mean to Buy Swaps?

Buying a swap means purchasing a contract that entitles the holder to specific financial payments under predefined conditions.

🔹 Buying an interest rate swap – fixing an interest rate to avoid exposure to rising rates.
🔹 Buying a currency swap – hedging against currency fluctuations.
🔹 Buying a CDS – insuring against a borrower’s default (or speculating on a company’s bankruptcy).

In the case of CDS, buying swaps essentially means betting on bankruptcy. If a company (or government) defaults, the CDS holder receives compensation.

How Did Investors Profit from Swaps in 2008?

1. What Happened?

In the mid-2000s, the U.S. saw a boom in mortgage lending, including risky subprime mortgages. These loans were bundled into securities (CDOs – Collateralized Debt Obligations) and sold to investors worldwide.

Large banks such as Lehman Brothers, Goldman Sachs, and Bear Stearns bought these securities, believing they were safe investments.

However, some investors realized the housing market was overinflated and that borrowers would struggle to repay their loans. These investors started buying CDS contracts to bet against mortgage-backed securities.

2. How Did They Make Money?

Financial institutions like Goldman Sachs and hedge funds, including Scion Capital (run by Michael Burry, whose story is depicted in The Big Short), started buying CDS contracts against mortgage bonds.

🔹 They paid small premiums for CDS contracts (essentially, insurance policies against mortgage defaults).
🔹 When the mortgage market collapsed in 2007–2008, many mortgage-backed securities became worthless.
🔹 CDS prices skyrocketed, as insurers like AIG and banks such as Lehman Brothers were forced to pay massive sums in compensation to CDS holders.

👉 Example: If someone bought a CDS contract for $1 million, after the mortgage collapse, they could receive a payout of $100 million or more.

3. Who Lost Money?

The major problem was that AIG and other large financial institutions sold too many CDS contracts without having enough capital reserves. When the market crashed, they couldn’t cover the losses, leading to the government bailout of AIG and the bankruptcy of Lehman Brothers.
