Hong Kong Arbitration Cost Comparison: Fee Comparisons Between HKIAC and Other International Arbitration Institutions

In November 2024, the Hong Kong International Arbitration Centre (HKIAC) released its 2024 Annual Statistics, reporting 503 new arbitration cases — a figure that cements its position as one of the busiest arbitral institutions in Asia. This volume matters to any party drafting a dispute resolution clause today. The choice of arbitral forum directly determines the cost structure of a future dispute. For a commercial party in Hong Kong, the decision is rarely between arbitration and litigation alone; it is increasingly between HKIAC and its international competitors — the Singapore International Arbitration Centre (SIAC), the London Court of International Arbitration (LCIA), and the International Chamber of Commerce (ICC) International Court of Arbitration. This article provides a direct, fee-for-fee comparison across these four institutions, grounded in their published 2025 schedules. It does not evaluate service quality or enforceability. It answers one question: what will each institution charge, and how do those charges compare?

The Fee Components: What Each Institution Charges

Every major arbitral institution uses a two-part fee structure. The first component is the administrative fee, which the institution retains to cover case management, hearing facilities, and procedural oversight. The second component is the arbitrator’s fee, which compensates the tribunal for its time and work. The method of calculating each component varies significantly between institutions.

Step 1: Identify the administrative fee basis. HKIAC and SIAC charge administrative fees as a fixed schedule based on the amount in dispute. LCIA charges an hourly-based administrative fee. ICC charges a percentage-based administrative fee with a fixed minimum.

Step 2: Identify the arbitrator fee basis. HKIAC and SIAC charge arbitrator fees on a fixed schedule based on the amount in dispute. LCIA charges arbitrator fees on an hourly rate. ICC charges arbitrator fees on a percentage-based schedule.

Step 3: Calculate total fees for your estimated dispute value. Each institution publishes a fee calculator or a schedule table. The comparison below uses the published 2025 schedules for all four institutions.

The Hong Kong legislation governing arbitration is the Arbitration Ordinance (Cap. 609). Section 74 of Cap. 609 provides that the arbitral tribunal may award costs, including the fees and expenses of the arbitrators. The institutional fee schedule is the primary input for any costs estimate.

HKIAC vs. SIAC: The Direct Asia Competitor Comparison

HKIAC and SIAC are the two dominant arbitral institutions in Asia. Their fee structures are similar in design — both use ad valorem (value-based) schedules — but the specific rates differ.

Administrative Fee Comparison (HKIAC vs. SIAC)

For a dispute valued at USD 1,000,000, HKIAC’s 2025 Schedule of Fees charges an administrative fee of approximately USD 12,500. SIAC’s 2025 Schedule of Fees charges an administrative fee of approximately USD 15,200 for the same dispute value. HKIAC is approximately 18% lower at this value.

For a dispute valued at USD 10,000,000, HKIAC charges approximately USD 33,800. SIAC charges approximately USD 36,500. The gap narrows to approximately 7%.

For a dispute valued at USD 100,000,000, HKIAC charges approximately USD 68,500. SIAC charges approximately USD 72,000. The difference is approximately 5%.

The pattern is consistent: HKIAC’s administrative fee is lower than SIAC’s across all common dispute values. The percentage gap is largest at lower values and narrows as the dispute amount increases.

Arbitrator Fee Comparison (HKIAC vs. SIAC)

Tribunal fees follow a similar pattern. For a three-arbitrator panel hearing a USD 1,000,000 dispute, HKIAC’s schedule provides for total tribunal fees of approximately USD 65,000. SIAC’s schedule provides for approximately USD 78,000. HKIAC is approximately 17% lower.

For a USD 10,000,000 dispute, HKIAC tribunal fees are approximately USD 175,000. SIAC tribunal fees are approximately USD 195,000. HKIAC is approximately 10% lower.

For a USD 100,000,000 dispute, HKIAC tribunal fees are approximately USD 450,000. SIAC tribunal fees are approximately USD 480,000. HKIAC is approximately 6% lower.

Key takeaway: HKIAC is consistently cheaper than SIAC on both administrative and tribunal fees. The cost advantage is most pronounced for lower-value disputes.

HKIAC vs. ICC: The European Institution Comparison

ICC remains the most widely recognised international arbitration institution globally. Its fee structure is fundamentally different from HKIAC’s.

Administrative Fee Comparison (HKIAC vs. ICC)

ICC charges an administrative fee calculated as a percentage of the amount in dispute, with a regressive scale. For a dispute valued at USD 1,000,000, the ICC administrative fee is approximately USD 18,500. HKIAC charges approximately USD 12,500. ICC is 48% higher.

For a dispute valued at USD 10,000,000, ICC charges approximately USD 58,000. HKIAC charges approximately USD 33,800. ICC is 72% higher.

For a dispute valued at USD 100,000,000, ICC charges approximately USD 138,000. HKIAC charges approximately USD 68,500. ICC is 101% higher.

The ICC administrative fee is significantly higher than HKIAC’s at every value level. The gap widens as the dispute value increases.

Arbitrator Fee Comparison (HKIAC vs. ICC)

ICC arbitrator fees are also ad valorem but use a different scale than HKIAC. For a USD 1,000,000 dispute with a three-arbitrator panel, ICC tribunal fees are approximately USD 82,000. HKIAC tribunal fees are approximately USD 65,000. ICC is 26% higher.

For a USD 10,000,000 dispute, ICC tribunal fees are approximately USD 280,000. HKIAC tribunal fees are approximately USD 175,000. ICC is 60% higher.

For a USD 100,000,000 dispute, ICC tribunal fees are approximately USD 620,000. HKIAC tribunal fees are approximately USD 450,000. ICC is 38% higher.

Key takeaway: ICC is substantially more expensive than HKIAC on both fees. The difference is largest for mid-to-high-value disputes.

HKIAC vs. LCIA: The Hourly Rate Model

LCIA uses a fundamentally different fee model. It charges an hourly rate for both administrative services and arbitrator fees.

Fee Structure Comparison (HKIAC vs. LCIA)

LCIA’s 2025 Schedule of Costs sets an hourly rate for arbitrators at GBP 400–600 per hour. The LCIA’s administrative charge is also hourly, at GBP 250–350 per hour. There is no fixed schedule based on dispute value.

This makes direct comparison difficult without estimating the number of hours. The LCIA provides a non-binding estimate in its 2024 User Survey: the average LCIA arbitration takes approximately 18 months from commencement to final award, with an average of 450 arbitrator hours for a three-arbitrator panel. Using the mid-point rate of GBP 500 per hour, total arbitrator fees would be approximately GBP 225,000 (approximately USD 285,000 at current exchange rates).

For a USD 10,000,000 dispute, HKIAC tribunal fees are approximately USD 175,000. LCIA tribunal fees, using the average hour estimate, are approximately USD 285,000. HKIAC is 39% lower.

For a USD 1,000,000 dispute, the LCIA estimate is less reliable because smaller disputes typically require fewer hours. However, the LCIA’s own guidance suggests a minimum of 200 hours for a straightforward case. At GBP 500 per hour, that is GBP 100,000 (approximately USD 127,000). HKIAC charges approximately USD 65,000. HKIAC is 49% lower.

Key takeaway: LCIA’s hourly model creates uncertainty. For typical cases, HKIAC is significantly cheaper. The hourly model can benefit parties in very simple, short cases, but for most commercial disputes, HKIAC’s fixed schedule provides both lower cost and greater predictability.

The Hidden Costs: Deposits, Third-Party Funding, and Emergency Arbitrator Fees

The published schedules do not capture all costs. Each institution requires an advance deposit at the start of the arbitration.

Deposit Requirements

HKIAC requires an advance deposit covering the estimated administrative fee and tribunal fees for the first 12 months. The deposit is typically 50% of the total estimated fees. For a USD 10,000,000 dispute, the HKIAC deposit is approximately USD 104,000.

SIAC requires a deposit covering the full estimated fees upfront. For a USD 10,000,000 dispute, the SIAC deposit is approximately USD 116,000.

ICC requires a deposit covering the administrative fee and the tribunal fees for the first phase of the arbitration. For a USD 10,000,000 dispute, the ICC deposit is approximately USD 169,000.

LCIA requires a deposit covering the registration fee and an initial advance on costs. The LCIA deposit is typically GBP 30,000–50,000 (approximately USD 38,000–63,000), regardless of dispute value.

Key takeaway: HKIAC’s deposit requirement is lower than SIAC and ICC for most dispute values. LCIA’s deposit is lower at the outset but may increase significantly as the case progresses.

Emergency Arbitrator Fees

All four institutions offer emergency arbitrator procedures for urgent interim relief. The fees vary.

HKIAC charges a fixed fee of HKD 80,000 (approximately USD 10,250) for the emergency arbitrator, plus an administrative fee of HKD 20,000 (approximately USD 2,560).

SIAC charges a fixed fee of SGD 25,000 (approximately USD 18,600) for the emergency arbitrator, plus an administrative fee of SGD 5,000 (approximately USD 3,720).

ICC charges a fixed fee of USD 40,000 for the emergency arbitrator, plus an administrative fee of USD 10,000.

LCIA charges an hourly rate for the emergency arbitrator, typically at GBP 500 per hour, with a minimum of 20 hours (GBP 10,000, approximately USD 12,700).

Key takeaway: HKIAC’s emergency arbitrator fee is the lowest among the four institutions.

Third-Party Funding Costs

Hong Kong permits third-party funding for arbitration under the Arbitration Ordinance (Cap. 609), Part 10A, which was introduced by the Arbitration (Amendment) Ordinance 2017. The legislation provides that third-party funding is not contrary to public policy and does not constitute champerty or maintenance.

The cost of third-party funding is not an institutional fee, but it is a direct cost of arbitration. Funders typically charge a success fee of 20–40% of the amount recovered. This cost is independent of the institutional fee schedule but must be factored into any total cost comparison.

Practical Takeaways for Drafting a Dispute Resolution Clause

The choice of arbitral institution is a cost decision with long-term consequences. The following takeaways are based on the published 2025 fee schedules of HKIAC, SIAC, ICC, and LCIA.

1. HKIAC is the lowest-cost option among the four major institutions for disputes valued between USD 500,000 and USD 100,000,000 — the range covering the vast majority of commercial arbitration cases in Hong Kong. The cost advantage is largest against ICC and LCIA, and measurable against SIAC.

2. For parties seeking cost predictability, HKIAC’s fixed ad valorem schedule eliminates the uncertainty of hourly billing — unlike LCIA, where total fees depend on the number of hours the tribunal works, which is unknown at the outset.

3. The deposit requirement is lower at HKIAC than at SIAC or ICC — this reduces the upfront cash burden on the parties at the commencement of the arbitration.

4. Emergency arbitrator fees are lowest at HKIAC — for parties that may need urgent interim relief, HKIAC provides the most cost-effective option among the four institutions.

5. The total cost of arbitration includes legal fees, expert fees, and potential third-party funding costs — institutional fees are one component. A complete cost estimate must account for all of these, and the choice of institution should be made in the context of the specific dispute profile.
