Cayman Islands SIBA License 2026 — Securities Investment Business Authorization Complete Guide
The Securities Investment Business Act (SIBA), as Revised, is the primary regulatory framework governing securities investment business in the Cayman Islands — and the Cayman Islands Monetary Authority (CIMA) is the regulator responsible for licensing, supervision, and enforcement. Any person or entity carrying on securities investment business in or from the Cayman Islands must hold either a full SIBA License or register with CIMA as a Registered Person, unless a specific exemption applies. SIBA covers four regulated activities: dealing in securities, arranging deals in securities, managing securities, and advising on securities — capturing the full range of investment firm activities from broker-dealers and market makers through fund managers, investment advisers, and securities arrangers. The Cayman Islands remains the world's most institutionally recognized offshore financial jurisdiction for hedge funds, private equity vehicles, and securities investment businesses — with 0% corporate tax, a 20-year Tax Exemption Certificate, full English common law, and 40 of the world's 50 largest banks maintaining Cayman presence. Capital requirements under SIBA: CI$100,000 (~USD $120,000) base financial resources for broker-dealers, market makers, and securities managers; CI$15,000 (~USD $18,000) for advisers and arrangers. Annual CIMA license fee: USD $10,000/year minimum. Annual declaration to CIMA: due 15 January each year. A new Prudential Information Survey requirement came into effect for the 2025 reporting year, with submissions required via CIMA's REEFS portal by 31 March 2026 — signaling CIMA's strengthened focus on prudential soundness across the securities investment business sector.
What Is Securities Investment Business?
Under SIBA, four categories of activity constitute “securities investment business” in or from the Cayman Islands:
Dealing in securities
Buying, selling, subscribing for, or underwriting securities as principal or agent. Captures broker-dealers, market makers, and proprietary trading desks operating in Cayman.
Arranging deals in securities
Bringing together parties for the purpose of transactions in securities, or acting as introducer for securities transactions. Captures placement agents, introducing brokers, and distribution agents.
Managing securities
Managing securities belonging to another person in circumstances involving the exercise of discretion. The core activity of discretionary fund managers and portfolio managers. This category also triggers Economic Substance Act requirements for fund management business.
Advising on securities
Giving advice to persons in their capacity as investors on the merits of investing in, acquiring, disposing of, or retaining securities. Captures investment advisers, research firms, and family office advisors.
Securities and crypto assets
SIBA's definition of “securities” is broad — shares, debentures, loan stock, bonds, depositary receipts, government securities, warrants, options, futures, and contracts for differences all fall within the definition. Importantly, crypto assets that function as investment instruments (equity-like rights, debt claims, profit participation, derivatives) are treated as securities under SIBA and require SIBA authorization alongside or instead of VASP Act registration.
SIBA License vs Registered Person — The Critical Distinction
The most important structural decision for any Cayman securities investment business is whether it requires a full SIBA License or can operate as a CIMA-registered Registered Person. The distinction determines your regulatory burden, compliance obligations, and the client categories you can serve.
| Feature | Full SIBA License | Registered Person |
|---|---|---|
| Issued by | CIMA (full authorization) | CIMA (registration) |
| Regulatory oversight | Higher — full supervision | Lower — registration framework |
| Client eligibility | Unrestricted | Restricted — sophisticated/HNW/institutional only |
| Capital (broker-dealer/manager) | CI$100,000 base financial resources | Same threshold applies |
| Capital (adviser/arranger) | CI$15,000 base financial resources | Same threshold applies |
| Annual CIMA fee | USD $10,000/year minimum | Lower (prescribed fee schedule) |
| Annual declaration | 15 January each year | 15 January each year |
| Prudential Information Survey | Required (from 2026) | Required (from 2026) |
| ES Act (discretionary managers) | Applies | Applies |
| PI insurance | Mandatory | Required |
| Best for | Retail-accessible operations, unrestricted client base | Fund managers serving CIMA-regulated funds, sophisticated investor pools |
Who qualifies as a Registered Person (Schedule 4, SIBA)
Entities serving CIMA-regulated funds (Schedule 4(1))
The most common category. A Cayman fund manager whose only clients are CIMA-regulated mutual funds or private funds qualifies as a Registered Person rather than needing a full license.
Entities serving only sophisticated or HNW persons (Schedule 4(4))
An entity whose clients are exclusively sophisticated investors (institutions, HNW individuals meeting financial thresholds) and which has a registered office or place of business serviced by a Cayman-licensed professional services provider.
Entities regulated overseas (Schedule 4(5))
An entity already regulated by a recognized overseas regulatory authority for securities investment business — such as an FCA-authorized, SEC-registered, or MAS-licensed firm — that also conducts Cayman securities business may register as a Registered Person rather than seeking a full SIBA license.
For most international fund managers and investment firms establishing a Cayman presence, the Registered Person route is the appropriate and more proportionate framework.
Capital and Financial Resource Requirements
SIBA licensees and Registered Persons must maintain base financial resources at all times:
Broker-dealers, market makers, securities managers
CI$100,000 (~USD $120,000) minimum base financial resources. This reflects the higher market and counterparty risk of principal-facing activities.
All other licensees (advisers, arrangers)
CI$15,000 (~USD $18,000) minimum base financial resources. This is the threshold for the largest category of SIBA participants — fund managers, investment advisers, and securities arrangers that do not act as principal.
Base financial resources is defined under the Securities Investment Business (Financial Requirements and Standards) Regulations and means the entity's net assets — total assets minus total liabilities — calculated on a prescribed basis. The entity must maintain these resources at all times and notify CIMA immediately if they fall below the minimum.
Mandatory Insurance
All SIBA licensees and Registered Persons must maintain adequate insurance coverage across three categories:
Professional Indemnity (PI) insurance
Coverage against claims arising from the firm's securities investment business activities — errors, omissions, negligence in advice or management.
Professional Liability of Senior Officers and Corporate Secretaries
Coverage for the personal liability of directors and senior officers in connection with their duties.
Business Interruption insurance
Coverage for operational disruption affecting the firm's ability to carry on securities investment business.
Insurance must be held with an insurer licensed to carry on domestic business in the Cayman Islands. CIMA's Statement of Guidance on Professional Indemnity Insurance is the operative guidance on coverage levels and policy requirements. This is one of the most commonly overlooked compliance requirements during SIBA application preparation — and a reason applications are returned as incomplete.
Economic Substance — What SIBA Managers Must Know
The International Tax Co-operation (Economic Substance) Act (ES Act) requires Cayman entities conducting certain relevant activities to demonstrate genuine economic substance in the Cayman Islands. For SIBA participants, the ES Act applies specifically to entities carrying on fund management business — defined as managing securities belonging to another person in circumstances involving the exercise of discretion.
In practical terms: any SIBA licensee or Registered Person conducting discretionary portfolio management or fund management is a Relevant Entity under the ES Act and must satisfy the Economic Substance Test (ES Test).
The ES Test requires:
- •Core income generating activities (CIGAs) conducted in the Cayman Islands — for fund managers, this means key investment decisions made by appropriately qualified employees present in Cayman
- •Adequate employees in Cayman relative to the management activity (can be part-time or via licensed management company)
- •Adequate physical presence and operating expenditure in Cayman
Entities that pass the ES Test file an Economic Substance Return (ESR) annually with the Cayman Department for International Tax Cooperation (DITC). Failure to satisfy the ES Test can result in financial penalties and CIMA notification. For fund managers using a Cayman-based licensed management company to provide CIGA personnel: this is the standard compliance approach and is fully accepted by CIMA and DITC when properly structured and documented.
Zitadelle AG advises on ES Act compliance structuring and provides CIGA documentation as part of the SIBA application and ongoing annual compliance service.
2026 Regulatory Updates — What Has Changed
Three material changes for SIBA participants in 2026:
Prudential Information Survey (new from 2026)
CIMA issued a General Industry Notice requiring all SIBA Registered Persons to submit a Prudential Information Survey for the 2025 calendar year via CIMA's REEFS portal by 31 March 2026. The Survey collects prudential and financial soundness data on each registered entity — an enhanced supervisory tool signaling CIMA's intent to increase transparency and resilience monitoring across the securities investment business sector. The Survey is submitted in addition to (not instead of) the annual declaration due by 15 January.
CIMA fee increases (effective 1 January 2026)
CIMA issued a notice of fee increases taking effect from 1 January 2026 across regulated sectors. SIBA licensees and Registered Persons should confirm current applicable fees via CIMA's published fee schedule when preparing annual renewal submissions.
CRS 2.0 and CARF (January 2026)
SIBA entities that are Financial Institutions under the CRS framework must ensure their Principal Point of Contact (PPoC) is Cayman-resident from registration (new entities) or by 31 January 2027 (existing entities). SIBA fund managers with digital asset exposure must also assess their CARF classification and registration obligations.

SIBA + Cayman Structural Advantages
0% corporate tax
No income, capital gains, profits, corporation, or withholding taxes for Cayman exempted companies and partnerships.
20-year Tax Exemption Certificate
Statutory guarantee of tax neutrality for 20 years from grant date, extendable to 30 years — providing certainty for long-term fund and investment business structures.
English common law
Cayman operates under English common law with the Privy Council as the final court of appeal. CIMA-authorized agreements and fund documents governed by Cayman law are accepted without challenge by institutional counterparties globally.
Institutional infrastructure
40 of the world's 50 largest banks have Cayman presence. Prime brokerage, custody, administration, and fund services infrastructure is as deep as any financial jurisdiction globally.
Fund ecosystem
The Cayman Islands is the #1 global jurisdiction for hedge funds, PE/VC funds, and alternative investment vehicles. SIBA authorization in Cayman is the natural counterpart to a Cayman fund vehicle — most institutional LP mandates assume Cayman GP/manager structures.
Tokenized funds (March 2026)
The Mutual Funds and Private Funds Amendment Acts (in force 24 March 2026) establish a regulated framework for tokenized fund interests within the CIMA framework — making SIBA-licensed Cayman fund managers the first globally to operate under a clear regulatory structure for blockchain-based fund tokenization.
Realistic Cost Breakdown
| Item | Cost |
|---|---|
| Cayman Exempted Company incorporation | USD $1,500–$3,000 |
| CIMA application fee (Registered Person) | USD $3,000–$6,000 |
| CIMA annual license/registration fee | USD $10,000+/year (licensees) |
| Base financial resources (adviser/arranger) | CI$15,000 (~USD $18,000) |
| Base financial resources (broker-dealer/manager) | CI$100,000 (~USD $120,000) |
| Annual TEC renewal | USD $1,000–$2,000 |
| Registered office / CSP service | USD $3,000–$8,000/year |
| PI insurance (mandatory) | USD $5,000–$20,000/year |
| AML/CFT compliance programme | USD $5,000–$15,000/year |
| ES Act compliance / CIGA services | USD $5,000–$15,000/year |
| Annual audit (if required) | USD $8,000–$25,000 |
| Total Year 1 (adviser/arranger route) | USD $40,000–$85,000 |
| Total Year 1 (broker-dealer/manager route) | USD $150,000–$250,000 |
Capital figures are held in the entity — not fees. The PI insurance and annual CIMA fee are the two most significant recurring costs for smaller SIBA participants.

Application Process
Step 1 — Corporate structure
Incorporate a Cayman Islands Exempted Company (or LP/foundation for certain structures) as the vehicle for the SIBA license or Registered Person registration.
Step 2 — Determine license vs registration
Assess whether the entity qualifies as a Registered Person under Schedule 4 of SIBA or requires a full license. This determines which application form, fee schedule, and compliance framework applies.
Step 3 — Director registration
Under the Director Registration and Licensing Act (DRLA), directors of SIBA licensees and Registered Persons must be registered or licensed with CIMA. All proposed directors must be in good standing under the DRLA before the SIBA application is submitted.
Step 4 — Application preparation
Complete application form APP-101-75 (Registered Person) or the equivalent license application, with all supporting documentation: business plan, compliance policies and procedures, AML/CFT policies, financial projections, director CVs and fitness documentation, insurance confirmation, and capital evidence.
Step 5 — Submission via REEFS portal
Applications submitted through CIMA's Regulatory Enhanced Electronic Forms Submission (REEFS) portal by the entity's registered office in Cayman.
Step 6 — CIMA review and approval
3–6 months for complete applications. CIMA may issue information requests during review. Fit and proper assessments of directors and senior officers conducted during review.
Step 7 — Annual compliance
Post-authorization — annual declaration by 15 January, Prudential Information Survey by 31 March, ESR filing (if applicable), AML/CFT reporting forms (AIR-157-75 and ARC-158-75), and maintenance of PI insurance.
