Separate capital, notional, collateral and settlement cash.
Futures can maintain index exposure while cash backs the account. That changes implementation; it creates neither another return source nor a freely spendable defensive allocation.
Posting €10,000 does not mean €10,000 exposure or a loss cap. A long future is an obligation, not an option premium buying a right you can leave unused.
Keep four amounts on separate lines
- Own capital
- Investor assets after liabilities and recognised gains/losses.
- Notional
- Reference size for futures-price sensitivity, not another owned asset.
- Initial margin
- Collateral within assets, subject to terms; not a purchase down payment.
- Settlement money
- Money reaching the required account/currency by its deadline.
CME’s institutional cash-equitization example illustrates handling flows while maintaining exposure. CFTC/CME distinguish collateral from a down payment; understanding this requires no personal contract selection or operating workflow.
Settlement reduces wealth once.
Both bars use one euro scale. Posted margin remains part of your own capital. The shorter second bar reflects the settled loss.
Before the price moveOwn capital €100,000
- Cash outside posted margin
- €90,000
- Posted margin
- €10,000
After cash settlementOwn capital €90,000
- Cash outside posted margin
- €80,000
- Posted margin
- €10,000
Exposure reference, not another asset
Notional: €100,000 → €90,000. The contract quantity is unchanged. Its book value is zero at this cash-settlement point.
- Outside €90,000 + posted €10,000 = €100,000.
- Pay €10,000 loss out: outside €90,000 + posted €0 = €90,000.
- Move €10,000 inside: outside €80,000 + posted €10,000 = €90,000.
Only step 2 reduces wealth. Step 3 restores margin.
The loss is 10% of initial capital and 100% of initial margin. Fixed margin is an illustration, not a quote or prescribed buffer.
Follow the payment and unchanged contract quantity
The unchanged contract quantity now has €90,000 current notional.
The initial €90,000 was not an independent spending reserve while backing the position. Daily settlement pays variation; additional intraday calls can occur. Paid losses are not another unpaid liability at settlement.
Cash interest is not a free addition to equity total return.
The combined result includes contract gains/losses, collateral return, embedded financing and implementation costs. Cash interest depends on provider terms.
Pricing, dividends and backing-asset risks
Conventional index-futures fair value relates the index, interest and expected dividends; actual prices can differ. The holder does not receive company dividends like a shareholder. Investor-specific tax, execution or financing terms create no universal advantage.
Long-duration or risky backing assets add price/liquidity risk. Their value can fall when settlement cash is needed, unlike the cash premise here.
The contract does not wait until expiry for payment.
Conventional futures are marked to market with daily variation settlement. Intraday calls and higher margin can occur; a broker may require more than the exchange minimum. Late payment can trigger liquidation.
- Today: call arrivesMoney exists elsewhere.
- Today: payment deadlineCash has not reached the required account.
- Tomorrow: transfer arrivesToo late to meet yesterday’s call.
Separate from the settled ledger. Invented dates; terms set actual deadlines and currency.
Full cash backing reduces economic leverage compared with using margin as the entire capital budget. It creates no contractual loss cap and removes neither access nor settlement risk.
Continuing exposure still needs replacement.
Contracts expire; replacement, transaction costs, pricing, settlement and delivery terms matter even when desired exposure stays unchanged.
Rolls and basis require their own comparison
Replacing expiry with a later contract is a roll.
The basis is a price difference between the future and cash index; state which price is subtracted from which. Financing/dividends help explain relationships, not every observed price. Not every contract-price difference is a broker fee or extra return. Assess tracking, collateral and deadlines without needing to execute the construction yourself.
Could a fund supply the exposure with less work?
Compare total costs, tax, tracking, access and responsibilities. Institutional use does not require personal adoption. A fund can delegate collateral/settlement work while retaining market risk; its exposure still needs a role in your portfolio.
