Hong Kong OTC Derivatives Clearing Threshold

Hong Kong’s OTC derivatives clearing regime uses a position threshold to identify major dealers that must centrally clear certain transactions. Do not treat the threshold as a rule that sends every OTC derivative trade to a clearing house. It is one condition in a transaction-level test.

Who measures the threshold

The Clearing Rules apply to authorized financial institutions, approved money brokers, and licensed corporations. For a locally incorporated institution or broker and for a local licensed corporation, the applicable position is the average total position. For an overseas institution or broker, the calculation generally uses the average local total position booked in its Hong Kong branch.

How the average is calculated

1. Identify the three-month calculation period listed in Schedule 2 to the Clearing Rules.
2. Take a position snapshot at each of the three month-ends in that period.
3. For a local person, total the notional amounts of the included outstanding OTC derivative transactions at each snapshot. For an overseas institution or broker, use the Hong Kong-booked local position.
4. Add the three snapshots and divide by three. This is a simple arithmetic average.
5. Compare the applicable average with the US$20 billion threshold. A value equal to the threshold counts as reaching it.

Gross position means no netting

The calculation uses gross notional amounts. Do not subtract an offsetting swap or net a position against a different trade. The calculation also has broader scope than the clearing mandate itself: count outstanding OTC derivative transactions generally, including trades that are exempt from clearing or outside the specified transaction types. Deliverable foreign-exchange forwards and swaps are excluded. Intra-company transactions between trading desks or branches of the same entity are also excluded as the SFC FAQs explain.

Reaching the threshold is not the whole test

The applicable threshold is US$20 billion for the calculation periods currently set out in the rules, according to the HKMA and SFC FAQs updated in October 2025. If the applicable average equals or exceeds it, the person is regarded as having reached the threshold. That status continues until the person gives a valid exit notice; falling below the threshold in a later period does not by itself switch the obligation off.

For clearing to be required, additional conditions must be satisfied. The trade must be a specified OTC derivative transaction, be entered into on or after the prescribed day for the calculation period in which the person first reached the threshold, and involve a counterparty that is also subject to the clearing obligation or is a designated financial services provider. The prescribed day is seven months after the end of the relevant calculation period. Historical trades are not made subject to clearing simply because the person later reaches the threshold.

A separate exit threshold

A person that has already reached the threshold may give an exit notice after its applicable position remains below US$14 billion—70% of the US$20 billion threshold—for 12 consecutive months, subject to the rules’ requirements. The person must document the relevant monthly positions and confirm that it has not returned to or above the exit threshold through the date of notice. An exit notice changes the person’s status; a later qualifying rise can bring it back into the regime.

Exam takeaway

Remember the calculation sequence: three month-end snapshots, gross notional positions, arithmetic average, compare with US$20 billion. Then separately test trade scope, prescribed day, and counterparty. Do not confuse reaching the threshold with a duty to clear every OTC derivative.

Determine who is measured and which class applies

Hong Kong’s mandatory clearing regime under the SFO applies to specified OTC derivative transactions and prescribed persons when the relevant conditions and threshold tests are met. A counterparty should identify its legal entity, group relationships, transaction types and prescribed person category before calculating the threshold. Different asset classes can have separate thresholds and calculation rules. Do not include or exclude a trade based solely on its label; check whether it falls within the statutory product definition and whether an exemption applies.

Calculate consistently and retain the basis

The threshold methodology generally uses a prescribed average gross notional position over the relevant calculation period, with no netting of long and short positions for the threshold calculation. Use the exact reference period, group aggregation and exclusions in the current SFC FAQ and subsidiary legislation. A robust process obtains complete data from affiliates and systems, validates currencies and notional amounts, documents any excluded trades, and independently reviews the calculation. If a group approaches a threshold, start preparatory work early rather than waiting for the reporting date.

Crossing the threshold is one part of a broader regime

Reaching the threshold can trigger mandatory clearing for specified transactions, but clearing is not the only OTC derivatives obligation. Reporting, record keeping, trading and risk-mitigation requirements may apply independently or on a different basis. The rules also provide conditions for a counterparty to cease being subject to mandatory clearing after falling below the applicable exit test. In a scenario, identify the person and product class, calculate the relevant gross position, apply the threshold and then state the consequence. Avoid treating a clearing threshold as a universal exemption from all OTC regulation.

Practical control and exam application

A compliance calendar should capture the calculation date and the period over which data must be aggregated. Establish ownership for affiliate data, identify missing valuations and escalate counterparties close to the relevant threshold. Once a threshold is crossed, promptly assess which new or outstanding trades are subject to clearing and which clearing arrangements must be in place. Retain the calculation and supporting source data so the firm can explain an apparent change in status. A single year-end snapshot may not satisfy an averaging test.
