What is an Equity Swap?
A swap is a financial contract that involves two counterparties exchanging cash flows over a regular period. An equity swap is a swap in which at least one of the cash flows is based on the performance of a stock or index (Chase, 2004; Cont, 2010; Faboozzi, 2008). One counterparty pays to the other the return or performance of a stock, basket of stocks or an equity index. In return the other counterparty pays a return based on a fixed interest rate, floating interest rate or another stock or index. For an equity swap in which one of the cash flows is based on a floating interest rate, this can be visualized in the diagram below:
The two cash flows in the above diagram are described as legs (Kozul, 2011, p.74). The cash flow based on the equity performance is referred to as the equity leg, and the cash flow based on interest rates is referred to as the financing leg.
From the above, and based on the nature of the cash flows exchanged there can be many variations of equity swaps. For example:
- one cash flow can be based of the performance of an equity underlying, while the other cash flow can be based on a floating interest rate. (A floating or variable interest rate is a rate that changes based on the market or some index).
- one cash flow can be based of the performance of an equity underlying, while the other cash flow can be based on a fixed interest rate
- one cash flow can be based of the performance of a foreign equity underlying denominated in a foreign currency. Depending on how the exchange rate is calculated, they may be termed compo or quanto equity swaps (Ramirez, 2011).
- Both cash flows can be based on the performance of different equity underlyings – Rainbow or Blended swaps (Eales and Moorad, 2003)
The cash flows may be exchanged once at the end of the contract, or they may be exchanged periodically during a notional reset.
Consider an equity swap with a financing leg based on a floating rate, as shown in the diagram. The party that pays the financing amount payments or floating amount and receives the equity performance payment (Party A) is called equity amount receiver. The party that pays out the performance of the equity underlying and receives the floating amount payments (Party B) is called the equity amount payer. The equity amount payer can be thought of as ‘carrying the underlying stock’ and is paid the floating amount to finance this holding. Equity swaps thus enable an investor to participate in the performance of an equity index without an initial investment or directly owning the stock. In this light, equity swaps can be viewed as a leveraged trading facility for Party A (Chase, 2004, p. 6).
When Party A and Party B enter into a swap contract, they decide on a currency amount on which the cash flows will be calculated. This amount is called an equity notional principal. (Chase, 2004; Cont, 2010). The notional is the underlying quantity on which payment obligations and interest rates are calculated. The payments are made on regularly scheduled dates over a specified period. At the start of the contract, the notional principal is equivalent to the value of the equity underlying on which the contract is based. To reduce for counterparty risk, the notional amount is recalculated or reset on specified valuation dates.
Equity Swaps are formalized through a confirmation. A confirmation document is an agreement that is legally subject to the ISDA mater agreement signed by the 2 parties.

- The contract states that the initial LIBOR rate is fixed on the trade date, and subsequent rates are set on the last floating amount payment date. Let’s assume that the rate on the trade date is 0.58563 % and 0.58313 % on 5th 2015, 0.58688% on 5th May 2015, 0.58375% and 5th Aug. 2015.
- Assume a dividend of 10p per share is announced on VOD.L on the 6th of July 2015, and is paid on the 12th of October 2015.
At the start of the swap contract, the value of the contract is zero. During the life of the swap, market conditions will change. As the price of the equity index changes, the 2 legs are valued separately, and the net value is paid/received.
- 5th Feb 2015 (1st Payment date)
Finance leg payment = notional * day count fraction * interest rate
Day count fraction = (Days between 5th Nov 2014 and 5th Feb 2015) / 360 = 92/ 365 = 0.256
Interest rate = libor + spread = 0.0058563 + 0.005 = 0.0108563%
Finance leg payment = £22,679,000 * 0.256 * 0.0108563% = £62,920.34
Equity leg payment = 0
- 5th May 2015 (2nd Payment Date)
Finance leg payment = notional * day count fraction * interest rate
Day count fraction = (Days between 5th Feb 2015 and 5th May 2014) / 360 = 89 / 365 = 0.247
Interest rate = libor + spread = 0.0058313 + 0.005 = 0.0108313%
Finance leg payment = £22,679,000 * 0.247 * 0.0108313% = £60,728.42
Equity leg payment = 0
- 5th August 2015 (3rd Payment Date)
Similar to the above, the finance leg payment will be £62,992.79 and the equity leg payment will be £0.
- 5th November 2015 (4th Payment Date)
Similar to the above, the finance leg payment will be £62,811.38 and the equity leg payment will be £0.
- 10th November 2015 (Settlement Date)
Finance Leg Payment = 0Equity Leg Payment = Capital Gains + Dividend Gains
Capital Gains = notional * % change in underlying.
% change in underlying = [(237.70 – 226.70 )/ 226.70 ] * 100% = 4.852%
Captial Gains = £22,679,000 * 5.69% = £1,100,436.70
Dividend Gains = Net Dividend * Number of Shares = 0.09 * 100,000 = £9,000.00
Equity Leg Payment = £1,100,436.70+ £9,000.00 = £1,109,436.70
During the term of the contract, ACME Ltd has made payments totalling £249,452.93 and received £1,109,436.70 in return based on an increase in Vodafone stock by 4.85%.
It is usual for the valuation date of long term equity swaps to coincide with their payment date of the finance leg. In that case, the parties exchange payments and the swap notional is reset for the next period (Ramirez, 2011).
Swaps can be cash-settled or physically settled. Cash settled swaps the equity swap receiver receives the equity appreciation in cash (and pays out the depreciation) (Ramirez, 2011). In physically settled swaps, on the termination date of the contract the equity amount receiver will receive a specified quantity of the equity underlying. In exchange the equity amount receiver will pay the equity amount payer the notional amount.
In return the equity swap receiver agrees to buy the underlying shares at an agreed price (and may receive dividend payments). In return, the equity swap receiver pays out a stream of interest payments to the equity swap payer. (Ramirez, 2011).
In price return equity swaps, the equity amount receiver gets the performance of the equity based only on the reference price – no dividend performance is included. In total return equity swaps, the equity amount receiver gets the performance of the equity, including any dividend payments (Ramirez, 2011).
- Portfolio diversification: For example, an investment fund may wish to diversify by minimising their exposure to a particular stock, but they may not wish to loose ownership of that stock. The fund can enter into a swap contract to pay out the performance of the stock, and in return receive the performance of a different stock or index. (Chase, 2004)
- International exposure: A client can use an equity swap to participate in the performance of an international stock without actually purchasing it.
- Low cost alternative: An equity swap could be seen as a cheaper alternative to other investment instruments that may achieve the same effect. For example, multiple futures contracts can achieve the same effect, but would attract higher transaction costs and taxes. Directly purchasing a stock or index is another alternative, but it may involve high funding costs, transaction costs, and if a large quantity is involved then availability may be an issue. Equity swaps on the other hand offer lower transaction costs, and involve no custodial costs, or withholding taxes for foreign equities (Chase, 2004; Eales and Moorad, 2003).
- Circumnavigate government restrictions: Equity swaps can be used to invest in foreign markets that may not be accessible due to government restrictions on the foreign ownership of stocks. Equity swaps can be used in this was as they allow investors participate in performance of the underlying but not directly own the shares (Merton, 1990; Eales and Moorad, 2003).
- Market invisibility: Selling a large quantity of a particular stock on the stock exchange could send a public signal to the market. As an OTC transaction, equity swaps can be used (for a limited time) to decrease a large exposure to a company’s stock without making it visible to the market. (Eales and Moorad, 2003).
- Significant cash flows: Involve significant cash flows that must be funded.
- Equity swaps cannot be open-ended: Equity swaps must have a termination date. Equity swaps can be used to mimic an equity position, but the contract must be re-established after it terminates to continue participating in the equity. (Chase, 2004).
- Credit risk: Equity swaps are subject to credit risk that does not occur when holding an equity directly – the swap dealer can default on their obligation.
When a swap contract is agreed, there is no cash exchanged up front. The interest rate on the finance leg is calculated so that the present value of the equity payments equals the present value of the interest payments. This means that at the start of the contract, it has zero market value. During the life of the swap contract, as market conditions change its value will no longer be zero. (Chase, 2004).
The ‘pricing of a swap’ refers to the interest rate used to determine the finance leg. However it is a misleading term as no price is determined. The interest rate is picked so that the market value of the swap at the beginning is zero (Chase, 2004).
For fixed rate equity swaps, the price (interest rate) is determined by the formula:
Once the dealer determines the interest rate, the dealer would include a premium into the rate charged the client, to cover the hedging costs and other costs involved in rendering the service. If the dealer is receiving the finance leg payments, the dealer would add a premium to the interest rate. Conversely if the dealer is making the fixed leg payments, the dealer would subtract a premium from the calculated rate (Chase, 2004).
