Forwards and Swaps: The Private Contracts
4 steps · one page
In short
Forwards and swaps are negotiated between two parties rather than traded on an exchange. That single fact — bilateral rather than centrally cleared — determines everything distinctive about them: they can be tailored to any requirement, and there is a specific counterparty whose failure is your problem.
Most readers will never enter one directly. Many already hold exposure to them: a synthetically replicating ETF obtains its index return through a total return swap, and this article closes the deferral that article made. Concept level, per the architecture — the purpose is that a reader encountering these instruments in a fund document understands what they are looking at.
Forwards: a futures contract without the exchange
A forward is an agreement to buy or sell something at a set price on a future date, negotiated privately. The economic idea is identical to a futures contract; the differences are institutional and they matter. Terms are customisable — any quantity, any date, any specification — which is why a business with a specific requirement uses a forward rather than forcing itself into a standardised contract. A company owing a foreign-currency payment of an unusual amount on an unusual date can fix exactly that. There is no daily settlement. Gains and losses accumulate until the contract matures rather than moving in cash every evening, which removes the interim liquidity demands futures impose — and replaces them with a single large obligation at maturity, plus a growing exposure to the counterparty's ability to perform. There is no clearing house. Your counterparty is a specific institution, not the market, so if it fails you have a claim against a failed institution rather than a guaranteed settlement. Collateral arrangements are increasingly used to mitigate this, and regulatory reform following the 2008 period has pushed substantial parts of the derivatives market toward central clearing and collateralisation precisely because bilateral exposure proved to be a systemic weakness. And liquidity is limited. A bespoke contract has no market; exiting typically means negotiating with the same counterparty or entering an offsetting contract, neither of which is guaranteed to be available on good terms. The practical summary: forwards trade flexibility for counterparty exposure and illiquidity. That is a sensible trade for an institution hedging a specific requirement and a poor one for anyone wanting a position they can exit.
Swaps: exchanging one stream for another
A swap is an agreement to exchange one series of payments for another over a period. Three families are worth recognising. Interest-rate swaps exchange fixed payments for floating ones on a notional amount — the classic use being a borrower with floating-rate debt who wants the certainty of a fixed cost, or the reverse. Note that the notional principal is typically never exchanged; only the payment difference moves, which is why a swap with a large notional can involve modest cash flows. Currency swaps exchange payments in different currencies, and unlike rate swaps often do involve principal. Total return swaps exchange the total return on an asset or index for a financing cost — and this is the one retail readers most likely hold indirectly, because it is the mechanism by which a synthetic ETF delivers an index return without owning the index constituents. The structure that article described is exactly this: the fund pays the return on a substitute basket and receives the index return, so the fund's holders are exposed to the swap counterparty for the difference. Credit default swaps deserve a mention as a fourth family: one party pays a periodic fee and receives a payment if a specified borrower defaults, which makes them insurance-like in structure while being tradeable instruments whose prices convey information about perceived credit risk — related to but distinct from credit spreads. Four things about swaps that matter for a reader encountering them in a fund document. Counterparty exposure is the defining risk, named plainly as the replication article named it, and bounded in regulated funds by exposure caps, collateral requirements, and frequent resets rather than eliminated. Collateral quality and its correlation with the counterparty matter — collateral that falls in value precisely when the counterparty fails is worth less than its posted figure. Valuation is model-based, since a bespoke bilateral contract has no market price, so the value carried in accounts is computed rather than observed and inherits every caveat the pricing article attached to model outputs. And the market is institutional. Swaps are not retail instruments, and the reason to understand them is not to use them but to know what a fund holds when its documentation says it holds one. One historical note, reported rather than dramatised: bilateral derivative exposure between large financial institutions was a significant transmission mechanism in the 2008 crisis, and the crisis pillar covers why. The regulatory response — central clearing for standardised contracts, mandatory collateral, trade reporting — was designed to reduce exactly that, and it has changed the market substantially without removing bilateral exposure where contracts remain bespoke.
Worked example
Worked example (fictional). Two illustrations, both of arrangements a reader might actually be exposed to. A forward, from the hedging side. Fictional Aurelis Foods must pay a European supplier €2.4 million in seven months. At today's rate that is about $2.20 million. Aurelis enters a forward with its bank to buy €2.4 million in seven months at a fixed rate, locking a cost of $2.23 million. Seven months later the euro has strengthened and €2.4 million would have cost $2.38 million at spot — so the forward saved $150,000. Had the euro weakened to make the spot cost $2.10 million, the forward would have cost Aurelis $130,000 relative to doing nothing. That symmetry is the point: a hedge removes uncertainty, not cost. Aurelis was not trying to profit; it was trying to know its costs when setting prices, and it accepted the possibility of a worse outcome in exchange for certainty. A total return swap, from the fund-holder side. A fictional synthetic ETF has $200 million of assets and holds government bonds as its substitute basket. It has a swap with two bank counterparties: it pays the return on that basket and receives the return on an emerging-markets index. Net exposure to each counterparty is bounded by a regulatory cap — under the EU fund rules such an ETF typically operates under, 10% of net assets per bank counterparty, so at most $20 million each, and in practice held well inside that by daily collateral posted at, say, 105% of exposure and frequent resets. So a holder of that ETF owns: government bonds, a swap position, and collateral — and receives emerging-market index returns. If a counterparty failed, the fund's recovery would depend on collateral value at that moment, not on the $200 million of assets being at risk. The exposure is bounded and it is not zero, which is the accurate statement and the one the fund's documentation makes. (All names and figures fictional; regulatory caps and collateral practice vary by fund regime.)
Frequently asked
8 questions
What's the difference between a forward and a future?
The economics are the same; the institutions differ. A forward is negotiated privately, so terms are fully customisable, there's no daily settlement, there's no clearing house standing behind it, and there's no market to exit into. Forwards trade flexibility for counterparty exposure and illiquidity.
Why would anyone use a forward instead of a future?
Because a specific requirement rarely matches a standardised contract. A business owing an unusual amount in a foreign currency on an unusual date can fix exactly that with a forward, and can avoid the interim cash demands that daily futures settlement imposes.
What is a swap?
An agreement to exchange one series of payments for another over a period. Interest-rate swaps exchange fixed for floating payments on a notional amount; currency swaps exchange payments in different currencies; total return swaps exchange the return on an asset or index for a financing cost.
Do I already own swap exposure?
Quite possibly, if you hold a synthetically replicating ETF. That fund delivers its index return through a total return swap: it pays the return on a substitute basket and receives the index return, so its holders are exposed to the swap counterparty. It's why reading a fund's replication method matters.
Is the whole notional amount at risk?
No, and this is worth understanding. In an interest-rate swap the notional principal is typically never exchanged — only the payment difference moves, which is why a swap with a large notional can involve modest cash flows. And in a fund context, exposure is capped by regulation and collateralised, so it's a fraction of assets rather than all of them.
What is a credit default swap?
One party pays a periodic fee and receives a payment if a specified borrower defaults — insurance-like in structure, while being a tradeable instrument whose price conveys information about perceived credit risk. Related to credit spreads but a distinct thing.
How is a swap valued if it doesn't trade?
By model. A bespoke bilateral contract has no market price, so the value carried in accounts is computed rather than observed — and it inherits every caveat that attaches to model-derived figures, including sensitivity to assumptions that may not hold.
Should I be worried about swaps in the financial system?
Bilateral derivative exposure between large institutions was a significant transmission mechanism in the 2008 crisis. The regulatory response — central clearing for standardised contracts, mandatory collateral, trade reporting — was designed to reduce exactly that, and it has changed the market substantially without removing bilateral exposure where contracts remain bespoke. This portal reports that record rather than drawing a conclusion from it.
