Singapore: A Leading Hub for International Arbitration (International Arbitration Laws and Regulations 2025)

Singapore has firmly established itself as a global leader in international arbitration, anchored by a modern legal framework and strong institutional support. According to the 2025 International Arbitration Survey released by Queen Mary University of London¹, it ranks among the top two most preferred arbitration seats globally.

In Global Legal Insight's International Arbitration Laws and Regulations 2025, Chenthil Kumarasingam, Jonathan Tan and Maria Santhosh examine the key features and developments shaping Singapore’s arbitration landscape.

A robust statutory framework

Singapore’s arbitration regime is built on two statutes:

• International Arbitration Act 1994 (IAA) — governing international arbitrations, adopting the UNCITRAL Model Law, and emphasizing minimal court intervention.
• Arbitration Act 2001 (AA) — covering domestic arbitrations, allowing greater scope for court oversight, including appeals on questions of law.

Courts play a supportive role, reinforcing finality and party autonomy.

Party autonomy and flexible agreements

Singapore courts take an expansive and pro-arbitration approach to interpreting arbitration agreements to respect parties’ intentions.

Key features include:

• Broad definitions of arbitration agreements, including electronic communications.
• Upholding clauses offering arbitration as an option alongside litigation.
• Recognizing references to external documents incorporating arbitration clauses.

Institutional and procedural versatility

Parties have a choice of:

• Institutional arbitration, with SIAC as a leading option.
• Ad hoc arbitration, offering maximum procedural flexibility.
• Statutory arbitration, in specified regulated contexts.

Procedurally, parties can choose between:

• The “pleadings” style common in common law jurisdictions.
• The “memorial” style, presenting comprehensive evidence and arguments upfront.
• Hybrid approaches adopting elements from both the 'pleadings' style and the 'memorial' style.

Modern funding and interim measures

Singapore permits third-party funding in both international and domestic arbitration. Under recent amendments:

• Disclosure of funding arrangements is required under the SIAC Rules.
• Tribunals can account for funding when apportioning costs.

Finality and enforcement

Arbitration awards in Singapore are:

• Final and binding, with limited grounds for challenge (e.g., incapacity, breach of natural justice, or public policy considerations).
• Readily enforceable under the New York Convention.
• Subject to strict confidentiality, though recent cases highlight exceptions when public interest or prior disclosures arise.

Investment arbitration leadership

Singapore continues to grow as a seat for investor–state disputes, supported by:

• 44 bilateral investment treaties and 21 FTAs with investment chapters.
• Evolving jurisprudence that strengthens procedural certainty and addresses transnational issues.
