With the prospect of Single Stock futures on U.S. names becoming available at CME Group in the summer of 2026, many investors are assessing the potential capital efficiencies and how these compare to the instruments and strategies they may be using today to access single names.
Single Stock futures can potentially benefit clients in the following manners:
- Allows investors to use less upfront capital
- Provides opportunity to clients to use that excess capital to earn a yield by reinvesting elsewhere
- The opportunity for investors to use that excess capital to scale up their position/exposure to a given single stock strategy
- Allows clients to easily go short, potentially at more efficient “implied borrow” levels and is operationally simpler than shorting physical stocks
- Provides institutional clients with an additional tool to manage equity financing on single name equities
Comparing different single stock implementation strategies
The minimum margin associated with a Single Stock futures contract at CME Group is 15%. This is significantly more capital efficient than clients who are either fully funding U.S. single stocks or using Reg T margin to finance a position. For retail traders, Reg T margin is available up to a maximum of 50%.
| Implementation strategy | Financing required | Notes |
|---|---|---|
| Single Stock futures | 15% (minimum) upfront | 85% (maximum) of funds that can be invested elsewhere and earn a return1 |
| Fully funded stock position | 100% upfront | No excess funds to reinvest elsewhere |
| Funding stock position at maximum Reg T margin | 50% upfront | Fund the position with 50% of up front capital and borrow 50% of margin on which interest needs to be paid2 |
One can compare the capital efficiency implications through simple scenarios with a few key assumptions:
Assumptions:
Nvidia share price = $200
Nvidia Single Stock futures price = $200
Multiplier of Single Stock futures contract = 100x
SSF margin = 15%3
Risk-free interest rate that can be reinvested in = 4%
USD financing that a retail client funds margined positions at = 6%
Scenario 1: Fully funded investor vs. Single Stock futures investor
In this scenario, it is assumed both investors have $20,000 of available capital.
The fully funded investor invests all $20,000 up front in order to buy 100 shares of Nvidia at $200 per share. They have zero leftover funds to invest in their portfolio.
A Single Stock futures investor can obtain the same level of exposure by purchasing one Single Stock futures contract on Nvidia (given the multiplier of the contract is 100x). The margin required is 15%, so this requires $3,000 of upfront capital (100 shares x $200 x 15%).
The remaining $17,000 in the client portfolio can be reinvested at the risk-free rate of 4%. That means for every day the investor keeps the position open overnight they will be receiving $1.89 of interest (17,000 x 0.04 x 1/360). So if the position is held for 3 months, this would equate to roughly $170 interest income.
An alternative strategy can be that if the investor wants to gain the maximum exposure to Nvidia with their given capital of $20,000, they could buy additional Single Stock futures and fund up to 6 Single Stock futures and thus have a position equivalent to 600 shares exposure to Nvidia (they would forego the opportunity to reinvest the $17,000 mentioned above).
The Single Stock futures contract is thus providing flexibility to the investor to either reinvest spare funds and earn a yield or scale their position given their funds available.
Scenario 2: Investor using 50% margin available via Reg T vs. Single Stock futures investor
Here in this example the assumption is the investor only has $10,000 of upfront capital but wishes to gain $20,000 of exposure to Nvidia.
In this case, the investor uses Reg T margin at 50% to fund a $20,000 exposure to Nvidia by using all the $10,000 of upfront capital they have available and then using broker financing to borrow the remaining $10,000 to fund the position.
Assuming the broker margin has an interest rate cost of 6% that works out to be $1.67 per day ($10,000 x 0.06 x 1/360), or equivalent to roughly $150 for a 3 month holding period.
This contrasts to a Single Stock futures contract where the upfront margin @ 15% only requires $3,000 to fund the position and the remaining $7,000 of available capital can be reinvested at a risk-free rate of 4%, resulting in the investor receiving interest of $70 over 3 months ($7,000 x 0.04 x 90/360).
Alternatively, the investor could choose to scale their position up using the remaining $7,000 and have a position of 3x the exposure they could facilitate through using Reg T margin @ 50%.
Caveats to note are that the above are simplified examples where the Single Stock futures price has been made equal to the share price. In reality they can be different. The difference is known as the “basis” which is determined by the implied financing in the futures contract and any dividends due before expiration. The implied financing will have an interest rate built in which likely offsets some of the interest income received in the examples above.
Comparing to OTC products such as single stock swaps
Institutional investors may use OTC swaps to gain exposure to single stocks, and any financing comparison analysis to Single Stock futures will depend on the swap rates involved (which differ from client to client). One important factor will be whether investors are subject to Uncleared Margin Rules (UMR), which require a minimum of 23%4 and can be higher depending on the sector of the single stock.5
Gaining short exposure
A further consideration of trading single stocks is that not every investor is looking to be long. Many traders are implementing relative value strategies where they are long one stock, short another or indeed have an outright short position on a stock.
For clients looking to short physical stocks, this involves arranging a “locate” and paying borrow fees, which are a percentage rate charge dependent on how hard to borrow the given stock is. This is both an operational burden as well as a cost, and the bid-offer on stock loans that clients pay can potentially be wide. Some investors can’t short physical shares at all but can do via a derivative such as a Single Stock futures contract.
If an investor is implementing a short position using Single Stock futures, the borrow fee of the underlying security is factored into the basis of the futures contract. This can often be at more effective pricing levels than the platform borrow fees many clients incur when shorting physical stocks. The reason this occurs is because the futures contract has a mix of long and short directional interest, and this supply/demand dynamic can result in more efficient “implied borrow” pricing.
The same logic can hold true versus single stock swaps where many clients are on swap platform pricing from their prime broker/swap provider and the market clearing borrow cost of the underlying asset is not necessarily what they are incurring.
Managing Equity Financing
Many institutional investors within the equity market are focused on managing their balance sheet and ultimately how they most effectively finance equity positions (sometimes also referred to as equity repo). We have seen for equity index exposure that clients use futures to help manage balance sheet efficiencies. Historically and in many cases today, this is achieved by using E-mini Equity futures on a given index such as the S&P 500.
An evolution of this has been Adjusted Interest Rate Total Return futures (AIR TRFs) which help isolate equity financing levels for a range of given tenors on an index such as S&P 500. Indeed AIR TRFs open interest has grown rapidly and is over $400bn notional as of June 2026. These products allow clients to manage equity financing by lending or borrowing equity positions to the market place at implied financing levels.
The AIR TRF product provides a transparent view of where implied funding levels are, as can be seen in the chart below. It highlights how the implied financing levels can move over time and how futures can be a tool to help manage this facet of equity risk.
The introduction of Single Stock futures on U.S. names will provide clients an additional tool in the toolkit to manage equity financing more easily. This will be in the same manner as Equity Index futures are used today, but with the precision of the specific equity financing level associated with a given single stock.
