A deep dive into market structure, operational efficiency and regulatory capital

How do FX futures differ from forwards or NDFs? This question is often asked by OTC FX participants who have heard about FX futures but unsure of their full characteristics.

FX futures and options from CME Group are centrally cleared products, well established within the global FX market. Average daily traded volumes of nearly $100 billion rival, if not exceed, those of major OTC spot FX venues, with participation from over 1,100 financial institutions in 2024. 

“Futurization,” taking what would traditionally be OTC trading in FX spot, forwards, NDFs, swaps and/or options and converting that trading to centrally cleared exchange-traded products, is available and being actively used by clients today in over 50 currency pairs.

Key distinctions between FX futures and OTC forwards

Trading mechanisms

Forwards: Typically traded bilaterally, leading to opaque and non-uniform pricing, and the potential for "last look" practices.

Futures: Exchange-traded, providing transparent observable prices on a central limit order book (CLOB). They offer firm pricing, anonymity and the ability to trade passively. Can also be traded bilaterally as per forwards.

Contractual and operational frameworks

Forwards: Require individually negotiated and often extensive bilateral agreements (e.g., ISDA documentation) and bilateral credit for each counterparty, resulting in complex and time-consuming onboarding processes.

Futures: Standardized contracts that do not require ISDA agreements or Prime Broker arrangements. Counterparty credit risk mitigated  due to central clearing, streamlining market access.

Post-trade advantages of futures

Regulatory exemption: FX futures are exempt from the Annual Aggregate Notional Amount (AANA) calculation, which can mitigate compliance burdens related to Uncleared Margin Rules (UMR).

Capital efficiency: Futures can incur significantly lower regulatory capital requirements for banks when compared to forwards, potentially leading to more favorable pricing for clients.

Tax implications: For U.S. entities, futures may qualify for advantageous 60/40 tax treatment under Section 1256 of the Internal Revenue Code. Other jurisdictions may have their own considerations.

Margin efficiency: Futures use the CME SPAN model for initial margin, which can be more efficient than the ISDA SIMM model used for OTC forwards. Cross-margining across correlated asset classes, such as FX and interest rates, are also available.

Variation margin: All variation margin payments for futures are netted to a single payment, simplifying reconciliation.

Physical delivery: In the major currency pairs, FX futures physically deliver into the two constituent currencies in the same CLS cycle as any spot or forwards positions, if held to final settlement.

Conclusion

While FX forwards remain a significant component of the global FX market, FX futures present a compelling alternative. They offer enhanced transparency, firm liquidity, anonymous trading capabilities and an efficient, regulated and centralized post-trade service. The benefits extend across various aspects, including streamlined trading, optimized margin and tax treatment, and improved capital efficiency.

When making a comparison between the futures market and the OTC market, clients can observe average bid-ask spreads in the CLOB of the futures market - for both outrights and for calendar spreads (rolls), but we would encourage customers to consider:

  • The ability to trade cleared futures and options using OTC-style trading, which allows the negotiation of trades with chosen LPs on a disclosed, relationship-based pricing model, potentially offering the same or even better pricing as regular OTC activity.
  • The ability to trade passively in the futures CLOB, allowing clients to avoid paying the spread and potentially earning the spread instead.
  • Tangible factors that impact the overall bottom line, such as tax, margin funding and interest earned on collateral balances.
  • Broader considerations such as removing/mitigating counterparty credit risk, trading anonymously and not needing to paper ISDAs, use credit lines or have limits imposed by a FX Prime Broker.

Impact of credit rating and CSA on pricing

Pricing is directly impacted by client credit rating and CSA terms.

None. Pricing is totally credit and CSA agnostic.

Firm pricing 

Depends on venue - most OTC streaming relationships have “last look.”

CLOB is firm pricing, with no last look (no rejects).

Counterparty credit risk

Bilateral credit risk vs. LP (or Prime Broker).

Credit risk removed from LP and FXPB due to central clearing.

ISDA (or PB arrangement)

Documents required for every fund against every chosen LP.

ISDAs or FXPB not required.

Yes - currently +415bps on USD cash.*

Cross margining

No

Portfolio margining between correlated asset classes (e.g. FX and rates).

Variation Margin

Daily movements versus every LP (or netted against PB).

All netted to one payment.

Capital considerations

CVA factored into pricing.
LP has to account for RWA (20%+) and SACCR.

Exempt from CVA.
RWA costs materially lower (2%).

Tax considerations

Potentially much higher capital gains tax.

U.S. entities could benefit from 60/40 tax treatment under section 1256.
Other jurisdictions may have their own considerations.
