Swaps Explained: A Step-by-Step Guide for Beginners

A swap is a derivative contract in which two parties agree to exchange cash flows or other financial instruments over a specified period. The most common types of swaps involve exchanging cash flows based on different interest rates, currencies, or other financial metrics. Swaps are typically used for hedging risks or speculating on changes in market conditions.


  • On Agreement: Two parties agree on the terms of the swap, including the notional principal (the amount on which the exchanged payments are based), the duration of the swap, and the schedule of payments.


  • Intermediate Exchange: The parties exchange cash flows according to the agreed schedule. For example, in an interest rate swap, one party might pay a fixed rate while receiving a floating rate, with payments made semi-annually.


  • On Settlement: At the end of the swap’s term, any final payments are made, and the swap contract is settled.



Interest Rate Swaps:

An interest rate swap involves the exchange of interest rate payments between two parties. One party pays a fixed interest rate, while the other pays a floating (variable) interest rate, based on a reference rate like LIBOR. A company with a floating-rate loan might enter into a swap to exchange its floating-rate payments for fixed-rate payments, thereby locking in a stable interest expense.


for example,

Party A has a loan with a floating interest rate of LIBOR + 1% on a $10 million notional principal.

Party B has a fixed-rate loan at 5% on the same notional principal but prefers a floating rate.


they enter into an interest rate swap agreement where:

Party A agrees to pay Party B a fixed rate of 4% on the $10 million notional.

Party B agrees to pay Party A the floating rate of LIBOR + 1% on the $10 million notional.


  • Every quarter, Party A pays the fixed 4% to Party B, and Party B pays the floating LIBOR + 1% to Party A.

  • Instead of exchanging the total interest payments, they only exchange the net difference between the two amounts. this simplifies the transaction and reduces credit risk.


this type of swap allows Party A to convert their floating-rate loan into a fixed-rate loan at 4%, while Party B effectively converts their fixed-rate loan into a floating-rate loan at LIBOR + 1%.


Currency Swaps:

In a currency swap, the parties exchange principal and interest payments in different currencies. This type of swap is used to hedge or speculate on currency fluctuations or to obtain financing in a foreign currency at a more favorable rate. A U.S. company needing euros might swap its dollar-denominated payments with a European company needing dollars, each benefiting from the other's currency access.


for example,

Party A (U.S. Company): Needs €10 million to expand operations in Europe but prefers to borrow in USD due to lower interest rates in the U.S.

Party B (European Company): Needs $10 million to expand operations in the U.S. but prefers to borrow in euros due to lower interest rates in Europe.


the two parties enter into a currency swap agreement:

  • Initial Exchange of Principal:

    • Party A exchanges $10 million for €10 million with Party B at the current exchange rate.

    • Party B now holds $10 million, and Party A holds €10 million.

  • Interest Payments:

    • Party A agrees to pay Party B interest on €10 million at the euro interest rate (let’s say 2%) quarterly.

    • Party B agrees to pay Party A interest on $10 million at the USD interest rate (let’s say 3%) quarterly.

  • At the end of the swap’s term, Party A will return €10 million to Party B, and Party B will return $10 million to Party A, regardless of any changes in the exchange rate.


  • Party A’s Obligation: Pays 2% annual interest on €10 million, which equals €50,000 per quarter, to Party B.

  • Party B’s Obligation: Pays 3% annual interest on $10 million, which equals $75,000 per quarter, to Party A.

The parties exchange these interest payments quarterly, with each party making payments in the currency they originally needed.


Scenario 1: If the euro strengthens against the dollar during the term of the swap,

  • Party A benefits because it originally locked in a lower exchange rate.

  • Party B benefits from having accessed dollars at a potentially lower cost than if it had borrowed directly in USD.


Scenario 2: If the euro weakens against the dollar,

  • Party A faces a higher cost when it eventually returns the euros to Party B at the swap's conclusion, but

  • Party B benefits from the favorable currency movement.


this illustrates how a currency swap allows Party A to access euros while locking in a fixed interest rate in euros and Party B to access dollars while locking in a fixed interest rate in dollars. Both parties benefit by avoiding direct exposure to potentially less favorable foreign exchange and interest rate conditions in the other’s market.


Commodity Swaps: 

Commodity swaps involve exchanging cash flows based on the price of a commodity, such as oil or gold. One party pays a fixed price, while the other pays a floating price based on the current market rate. An airline might use a commodity swap to lock in the price of jet fuel, thereby protecting itself against rising fuel costs.


for example,

Party A (Airline): Wants to lock in the price of jet fuel to protect against potential price increases over the next year.

Party B (Oil Producer): Wants to hedge against the possibility of falling oil prices, ensuring a stable income.


the two parties enter into a commodity swap agreement:

Notional Quantity: The swap is based on 1 million barrels of jet fuel.

Party A agrees to pay Party B a fixed price of $80 per barrel of jet fuel over the next year.

Party B agrees to pay Party A the market price of jet fuel at the time of settlement, based on the current market rate.

  • At the end of each month, the market price of jet fuel is determined. Party A’s Obligation: Pays the fixed price of $80 per barrel to Party B. Party B’s Obligation: Pays the floating market price per barrel to Party A.

  • Only the difference between the fixed and floating prices is exchanged, rather than the full price, reducing the amount of money that changes hands.


Scenario 1: Market Price Rises: If the market price of jet fuel rises to $90 per barrel:

  • Party A continues to pay $80 per barrel to Party B.

  • Party B pays $90 per barrel to Party A.

Party B pays Party A the difference of $10 per barrel, helping Party A offset the higher market price.


Scenario 2: Market Price Falls: If the market price of jet fuel falls to $70 per barrel:

  • Party A continues to pay $80 per barrel to Party B.

  • Party B pays $70 per barrel to Party A.

Party A pays Party B the difference of $10 per barrel, providing Party B with protection against falling prices.


this illustrates how a commodity swap allows Party A (the airline) to stabilize its fuel costs by locking in a fixed price, protecting against rising fuel prices. Meanwhile, Party B (the oil producer) secures a guaranteed price for its product, protecting against potential price declines. The swap enables both parties to manage their exposure to commodity price volatility effectively.


Equity Swaps:

In an equity swap, two parties agree to exchange cash flows based on the performance of an equity asset, such as a stock or an equity index, over a specified period. The cash flows exchanged typically involve one party paying a return based on the performance of the equity asset, while the other party pays a return based on another financial metric, such as a fixed interest rate, a floating interest rate, or the performance of another equity or asset class.


for example,

Party A: Owns a portfolio of stocks but wants to diversify the portfolio's return by gaining exposure to a different asset class without selling their stocks.

Party B: Prefers to gain exposure to the stock market but currently has a fixed-income investment that pays a fixed interest rate of 4%.


the two parties enter into an equity swap agreement:

Party A: Agrees to pay Party B the total return on a stock index (SnP 500) on a notional principal of $10 million.

Party B: Agrees to pay Party A a fixed interest rate of 4% on the same $10 million notional principal.


  • At the end of each quarter, Party A calculates the total return on the SnP 500 index, which includes both the capital gains or losses and any dividends paid out during the quarter.

  • Party B calculates the fixed interest payment at 4% annually on the $10 million notional, which comes to $100,000 per quarter.


  • If the SnP 500 index return is positive and exceeds the 4% fixed interest, Party B pays Party A the difference between the index return and the fixed rate.

  • If the SnP 500 index return is negative or below the 4% fixed interest, Party A pays Party B the difference.


Scenario 1: The SnP 500 index returns 6% over the year (1.5% per quarter).

  • Party A's Obligation: Party A owes 1.5% of $10 million ($150,000) to Party B for the quarterly index return.

  • Party B's Obligation: Party B owes 1% of $10 million ($100,000) to Party A for the quarterly fixed interest payment.

Party B pays Party A $50,000.


Scenario 2: The SnP 500 index returns 2% over the year (0.5% per quarter).

  • Party A's Obligation: Party A owes 0.5% of $10 million ($50,000) to Party B for the quarterly index return.

  • Party B's Obligation: Party B owes 1% of $10 million ($100,000) to Party A for the quarterly fixed interest payment.

Party A pays Party B $50,000.


this illustrates how an equity swap allows Party A to diversify into fixed income while retaining exposure to the stock market, and Party B to gain stock market exposure while continuing to earn fixed income. The cash flows exchanged depend on the relative performance of the SnP 500 index versus the fixed interest rate.


Credit Default Swaps (CDS): 

A credit default swap is a type of swap that acts like insurance against the default of a borrower. One party pays a periodic fee (premium) to another party, who agrees to compensate the first party if a specified credit event, like a default, occurs. An investor holding corporate bonds might buy a CDS to protect against the risk of the bond issuer defaulting on its debt.


Swaps are often used to hedge against risks such as interest rate fluctuations, currency exchange rate changes, or commodity price volatility. Traders may also use swaps to speculate on changes in market conditions without needing to own the underlying assets. Companies may use swaps to obtain more favorable loan terms or to manage cash flows in different currencies.
