HKIAC has released its 2025 case statistics, reporting 388 arbitrations with US$16.2 billion in total dispute value. This article examines the key statistics in context, comparing them against prior years and analysing their practical implications.
1. Caseload Growth and International Character
HKIAC has established itself as a leading arbitration institution for Asia-Pacific disputes, with particular strength in China-connected and corporate matters. The 2025 caseload of 388 arbitrations represents a 10% increase from 352 in 2024. More significantly, the international character of the caseload increased from 76.4% to 84.3%, indicating that HKIAC is becoming more international.
| Metric | 2025 | 2024 | Change |
| Total Arbitrations | 388 | 352 | +10% |
| Administered Arbitrations | 281 | 249 | +13% |
| International Cases | 84.3% | 76.4% | +7.9 percentage points |
| Total Sum in Dispute | US$16.2 billion | US$13.6 billion | +19% |
| Average Case Value (administered) | US$53.7 million | US$48.1 million | +12% |
| Jurisdictions represented | 61 | 53 | +15% |
The increase in international cases is notable in the current geopolitical context. Additionally, 45.4% of arbitrations involved no Hong Kong parties, and 58.2% involved no Mainland Chinese parties. This indicates that parties select HKIAC as a neutral international forum, not solely for Hong Kong-China disputes.
The top party jurisdictions were Hong Kong, Mainland China, BVI, Cayman Islands, and Singapore. The prominence of BVI and Cayman Islands reflects Hong Kong’s role as a structuring hub, as many cross-border investments use holding structures incorporated in these jurisdictions.
2. The Interim Measures Arrangement Continues to Deliver Results
The Hong Kong-Mainland China Interim Measures Arrangement, which came into force in October 2019, allows parties to Hong Kong-seated arbitrations administered by specified institutions (including HKIAC) to apply directly to Mainland Chinese courts for asset preservation, evidence preservation, or conduct preservation.
This pathway is not available for arbitrations seated elsewhere. If an arbitration is seated in London, Singapore, or any other jurisdiction outside Hong Kong, Mainland Chinese courts will not grant interim measures in support of that arbitration.
| Interim Measures Arrangement | 2025 | Cumulative (since October 2019) |
| Applications processed | 34 | 178 |
| Value of assets sought to be preserved | USD 1.6 billion | USD 6.4 billion |
| Value of assets actually preserved | USD 720 million | USD 4.6 billion |
| Court decisions granting preservation | 17 | 126 of 133 (95%) |
| Mainland courts involved | 13 | — |
The 95% grant rate (126 of 133 cumulative decisions) indicates that Mainland Chinese courts are granting these applications when properly made, and as a result of this mechanism, US$4.6 billion in assets have been preserved since 2019.
The user profile is also significant: in 2025, 55.1% of applications concerned assets owned by non-Mainland parties (from BVI, Cayman Islands, Hong Kong, Singapore, Japan, Australia, Italy, Taiwan, and the USA). International parties (not only Chinese parties) are actively using this arrangement to secure assets in Mainland China.
For transactions where the counterparty has significant assets in Mainland China, this mechanism may be determinative of seat and institution selection.
3. Corporate and Shareholder Disputes Dominate the Caseload
HKIAC’s dispute category breakdown reveals a distinctive concentration in corporate and shareholder matters. At 23.6% of caseload, this category is HKIAC’s largest, and higher than comparable institutions.
| Dispute Category | 2025 Percentage | 2024 Comparison |
| Corporate and Shareholder Disputes | 23.6% | 23.0% (Corporate + Shareholder combined) |
| Maritime | 19.9% | 12.2% |
| Sale of Goods | 14.2% | 13.9% |
| Commercial | 10.9% | 14.5% |
| Construction | 9.2% | 9.7% |
| Financial | 7.7% | 7.7% |
| Cryptocurrency and Blockchain | 7.2% | 3.1% |
This concentration reflects Hong Kong’s role as a listing venue, holding structure hub, and gateway for investment into China. When shareholders in BVI/Cayman holding structures dispute, the arbitration frequently proceeds at HKIAC.
The Maritime category’s increase to 19.9% (from 12.2% in 2024) reflects Hong Kong’s continued importance as a shipping centre. The Cryptocurrency category’s increase to 7.2% (from 3.1%) is addressed separately below.
4. Multi-Contract Complexity Is Now Routine
Modern transactions typically involve multiple interconnected agreements such as shareholders agreements, subscription agreements, licensing agreements, and management agreements, which may all relate to the same investment. Disputes arising from these structures frequently cut across multiple documents.
HKIAC’s 2025 statistics demonstrate that this complexity is now routine: the 388 arbitrations arose from 578 contracts (an average of 1.49 contracts per arbitration), involved 1,233 parties (an average of 3.2 per arbitration), and 185 arbitrations (48%) involved multiple parties or contracts.
| Complexity Metric | 2025 | Implication |
| Total Contracts across 388 arbitrations | 578 | Average 1.49 contracts per case |
| Total Parties across 388 arbitrations | 1,233 | Average 3.2 parties per case |
| Multi-party or Multi-contract cases | 185 (48%) | Nearly half of all arbitrations |
| Single Arbitration under Multiple Contracts | 96 | Mechanism is well-established |
| Consolidation Success Rate | 86% (12 of 14) | High likelihood of success |
| Joinder Success Rate | 69% (9 of 13) | Majority of cases succeed |
The 86% consolidation success rate and 69% joinder success rate indicate that these mechanisms function effectively. For parties facing related arbitrations, early application for consolidation is advisable. For parties needing to add additional parties, joinder is worth pursuing. For parties who intend to resist consolidation or joinder, please note that the success rate for resisting such an application is low to medium.
For transaction structuring, consistent arbitration clauses across all documents are important. Inconsistent clauses (different seats, different institutions, incompatible appointment mechanisms) can preclude consolidation even where the underlying disputes are closely connected.
5. Emergency Arbitrators Are Appointed in Hours
HKIAC’s emergency arbitrator mechanism provides rapid relief in disputes where waiting for tribunal constitution is not viable.
In 2025, HKIAC appointed emergency arbitrators in an average of 15 hours and 11 minutes. Emergency arbitrators rendered decisions in an average of 12.1 days.
| Emergency arbitrator metric | 2025 | Cumulative |
| Applications | 9 | 49 |
| Average time to appointment | 15 hours 11 minutes | – |
| Average time to decision | 12.1 days | – |
For China-connected disputes, emergency arbitrator orders are not directly enforceable in Mainland China (there is no formal mechanism for Mainland courts to recognise them). Parties seeking urgent relief specifically in Mainland China may apply to Mainland courts under the interim measures arrangement. Some parties use both mechanisms in parallel: emergency arbitrator for immediate relief enforceable outside China, plus Mainland court application for China-specific asset preservation.
6. Cryptocurrency Disputes Emerge as a Distinct Category
Cryptocurrency and blockchain disputes represented 7.2% of HKIAC’s 2025 caseload, up from 3.1% in 2024. This is now larger than aviation (1.7%), professional services (1.7%), intellectual property (1.2%), or insurance (0.5%).
Hong Kong has developed a regulatory framework for virtual assets. The SFC’s mandatory licensing regime for virtual asset trading platforms took effect in June 2023, and by 2025, multiple platforms had received full licenses. The HKMA issued its first stablecoin licenses in early 2026. As this regulated ecosystem matures, commercial disputes, such as exchange-related disputes, token disputes, and investment disputes involving digital assets, inevitably follow.
Arbitration is suited to these disputes given their cross-border nature, confidentiality considerations, and the flexibility to appoint arbitrators with relevant technical expertise. Given the speed at which digital assets can be transferred, emergency arbitrator provisions are particularly relevant for this sector.
7. Arbitrator Appointments Reflect International Diversity
HKIAC made 176 direct appointments of arbitrators in 2025. Appointed arbitrators came from 23 jurisdictions, with Hong Kong (34.5%), UK (16.3%), and Australia (12.9%) representing the largest shares.
| Arbitrator Origin | 2025 Percentage | Number |
| Hong Kong | 34.5% | 72 |
| United Kingdom | 16.3% | 34 |
| Australia | 12.9% | 27 |
| New Zealand | 5.7% | 12 |
| Singapore | 5.7% | 12 |
| Canada | 4.8% | 10 |
| Mainland China | 4.3% | 9 |
| France | 2.9% | 6 |
| Other (15 jurisdictions) | 13.5% | 24 |
Gender diversity in HKIAC appointments reached 36.4% female in 2025 (64 of 176 direct appointments), up from 34.7% in 2024.
Challenges to arbitrators remained rare: 4 challenges were submitted in 2025, and all 4 were dismissed.
8. Conclusion
The 2025 statistics reflect HKIAC’s continued growth and its distinctive position among international arbitration institutions. Three aspects merit particular attention:
- The interim measures arrangement provides a unique pathway to asset preservation in Mainland China. The cumulative USD 4.6 billion in preserved assets and 95% grant rate demonstrate this mechanism’s practical effectiveness. For transactions with China exposure, this may be determinative of seat and institution selection.
- Corporate and shareholder disputes dominate HKIAC’s caseload at 23.6%, reflecting Hong Kong’s role as a structuring and investment hub. The institution has substantial experience with the specific issues arising in private equity exits, JV breakdowns, and founder disputes.
- Multi-contract complexity is now routine, with 48% of arbitrations involve multiple parties or contracts, and the consolidation success rate of 86% indicates the procedural mechanisms function effectively.
The data supports informed decision-making about arbitration clause drafting. Parties should consider whether the interim measures arrangement is relevant to their transaction, whether consistent clauses across transaction documents would facilitate consolidation, and whether emergency arbitrator provisions should be retained given the dispute types they may face.
