What it means
The contract is built on a notional amount, an agreed sum that is never exchanged but is used to size the payments. If the equity leg is based on an index that rises 6%, the party paying the equity return pays 6% of that notional, while receiving an agreed interest rate on the same figure.
Investors use equity swaps for reasons that come down to access and efficiency. A fund may want exposure to a market where it cannot easily hold shares directly, or a company may want the returns of an index without the administration of buying and holding hundreds of positions.
Corporates use them too, most often to hedge obligations. A business with a share based bonus scheme faces a rising cost if its own share price climbs, and an equity swap referencing that price can offset the cost without the company buying its own shares.
The risks are real and worth naming. Because the contract is negotiated directly between two parties rather than traded on an exchange, each side carries the risk that the other fails to pay, and the notional amount means losses can be far larger than any cash originally put up.
Equity swaps have also attracted regulatory attention because they can build economic exposure to a company without triggering the disclosure rules that apply to buying shares outright. That has been the source of several high profile disputes about hidden stake building.
In practice
Real-world examples.
Example
A European pension fund wants exposure to an Asian share index but faces local ownership restrictions and heavy custody costs. It enters an equity swap with an international bank instead, receiving the index return in exchange for a floating rate payment.
Example
A listed company operates a cash settled bonus plan tied to its own share price and faces an unpredictable charge each year. It uses an equity swap referencing its shares so that gains on the swap offset the rising cost of the bonus.
Example
A hedge fund holds a large long position in a single share through a swap rather than buying the stock, allowing it to take a position several times the size of the cash it has committed. When the share falls 15%, the losses on the swap far exceed the initial collateral posted.
Think of it
“Equity swap trades stock returns for other payments-synthetic stock exposure through a swap.
Formula
Calculation
Net settlement = (equity return % x notional) - (floating rate % x notional)
An investment fund enters a one year equity swap on a notional amount of $50,000,000. The fund receives the total return on a broad share index and pays a floating rate of the benchmark rate plus 0.5%. Over the year the index returns 6%, and the benchmark rate averages 4.5%, making the floating leg 4.5% + 0.5% = 5%.
The equity leg is worth $50,000,000 x 0.06 = $3,000,000 to the fund, and the floating leg it owes is $50,000,000 x 0.05 = $2,500,000. The counterparty therefore pays the fund a net $3,000,000 - $2,500,000 = $500,000. Had the index instead fallen 4%, the fund would owe $50,000,000 x 0.04 = $2,000,000 on the equity leg plus the $2,500,000 floating payment, a net cost of $4,500,000, which shows how quickly the position turns against you.Case study
Seen in the real world.
The following is an illustrative and fictional account. Brackenfield Capital, an invented asset manager, wanted exposure to a technology index for six months while it completed a review of its direct holdings. Buying and then selling the underlying shares twice would have cost an estimated $340,000 in dealing charges and taxes.
Instead it entered an equity swap on a $200,000,000 notional with a large bank, receiving the index return and paying a floating rate. The index rose 4% over the period, so Brackenfield received $8,000,000 on the equity leg and paid roughly $5,000,000 on the floating leg over the six months, a net receipt of about $3,000,000 with none of the dealing costs.
The fictional risk committee still insisted on two conditions before approving it, and they are the standard ones: daily collateral exchange to limit exposure if the bank failed, and a hard limit on total notional across all swap counterparties. Without those, a contract that saved $340,000 could have exposed the fund to a loss many times larger.
Watch out
Common mistakes.
- Thinking of the notional amount as the money at stake, when the actual exposure is the change in value of both legs and can move far faster than any initial deposit suggests.
- Ignoring counterparty risk because the contract is with a large bank, since a swap is a private agreement with no exchange standing behind it.
- Assuming an equity swap gives the rights of share ownership, when the holder receives economic returns but no voting rights or shareholder register entry.
Questions
People also ask.
Why would anyone use a swap rather than just buying the shares?
Access to restricted markets, lower dealing and custody costs, and the ability to gain exposure without tying up the full purchase price.
Are equity swaps only for large institutions?
In practice yes, because they are negotiated privately in sizeable amounts with collateral arrangements that individual investors rarely have.
What happens if the index falls?
The party receiving the equity return has to pay that fall to the counterparty as well as paying its floating leg, so both sides of the trade can move against it at once.
