Cross-Border Marketing Restrictions for Trading Platforms

📅 Updated Sept 2025 ⏱ 15 min read 🌐 International Compliance

The Global Marketing Minefield

In my practice advising trading platforms, I consistently see founders underestimate the complexity of marketing to international investors. The internet makes it trivially easy to reach users worldwide, but securities regulations were written for a world of national borders. This creates a dangerous disconnect.

When a US-based trading platform accepts a user from Germany or Singapore, it may have just triggered registration requirements, licensing obligations, and potential enforcement actions in those jurisdictions. I advise clients to think of international marketing not as an opportunity, but as a compliance minefield requiring careful navigation.

⚠ The Stakes Are High

Cross-border marketing violations can result in criminal liability for executives, platform shutdowns, and being permanently barred from major markets. I have seen startups receive cease-and-desist letters from the FCA, MAS, and SFC simultaneously after aggressive international marketing campaigns.

Marketing to Non-US Investors from US Platforms

When I help US-based trading platforms expand internationally, the first question is always: "Where does US jurisdiction end and foreign jurisdiction begin?"

The Conduct and Effects Test

US securities laws apply based on where the conduct occurs and where the effects are felt. For a US-based platform:

Regulation S Considerations

When offering securities to non-US persons, I typically advise clients to structure offerings under Regulation S, which provides a safe harbor from SEC registration for offshore transactions. Key requirements:

💡 The Platform vs. Securities Distinction

Marketing a trading platform (software) internationally is different from marketing securities internationally. I always help clients clearly delineate what they're offering. Pure software-as-a-service may have fewer restrictions than a platform that also offers investment products.

Reverse Solicitation: Understanding the Exception

Reverse solicitation is the most frequently invoked, and most frequently abused, concept in cross-border financial services. I spend considerable time helping clients understand what it actually means.

What Reverse Solicitation Actually Is

True reverse solicitation occurs when a prospective client initiates contact with a financial services provider entirely on their own initiative, without any prior marketing, advertising, or solicitation by the provider. The key elements:

What Reverse Solicitation Is NOT

In my practice, I regularly have to disabuse clients of the following misconceptions:

⚠ The Documentation Burden

If you rely on reverse solicitation, you must maintain bulletproof documentation of the client's unsolicited approach. This means timestamped records of first contact, absence of prior marketing exposure, and the specific products/services requested. In my experience, regulators view reverse solicitation claims with deep skepticism.

Jurisdiction-Specific Approaches

JurisdictionReverse Solicitation RecognitionDocumentation Required
EU (MiFID II) Recognized but narrowly interpreted Detailed records, burden on firm
UK (FCA) Limited recognition post-Brexit Strict documentation, FCA guidance
Singapore (MAS) Not formally recognized N/A - requires licensing or exemption
Hong Kong (SFC) Limited professional investor exception Professional investor certification
Switzerland (FINMA) Recognized for qualified investors Investor qualification documentation

EU MiFID II Marketing Restrictions

The Markets in Financial Instruments Directive II (MiFID II) creates one of the most complex regulatory environments for cross-border marketing. When I advise clients on EU market access, I emphasize that "passporting" is no longer available to non-EU firms post-Brexit and post-equivalence decisions.

🇪🇺 EU Access Routes

  • Third-Country Branch: Establish physical presence in EU member state
  • Reverse Solicitation: Client-initiated only, strict documentation
  • Equivalence Regime: Currently unavailable for US
  • Professional Clients Only: Some member states allow limited access

National Private Placement Regimes

In absence of EU-wide third-country access, I typically advise clients to navigate individual member state regimes:

💡 The ESMA Position

ESMA has issued clear guidance that websites accessible in the EU, combined with services available to EU residents, constitutes marketing in the EU. In my practice, I advise clients that geo-blocking alone is insufficient; you need comprehensive EU access controls or proper licensing.

Retail vs. Professional Clients

MiFID II distinguishes between retail and professional clients, with significantly different treatment:

Client TypeAccess for Non-EU FirmsRequirements
Retail Clients Generally prohibited without EU authorization Full MiFID compliance, EU branch or license
Professional Clients National regimes may permit limited access Varies by member state, notification often required
Eligible Counterparties Most flexible access Fewer conduct requirements, but still needs legal basis

UK Financial Promotions Regime

The UK operates one of the most stringent financial promotions regimes globally. Post-Brexit, this has become entirely separate from EU rules, creating additional complexity for platforms seeking to serve both markets.

🇬🇧 UK FCA Requirements

  • Section 21 FSMA: Financial promotions must be approved by authorized person
  • Overseas Person Exclusion: Limited, requires no UK solicitation
  • High Net Worth/Sophisticated: Exemptions with strict certification
  • Criminal Offense: Unapproved promotions carry criminal penalties

The Section 21 Problem

Under Section 21 of the Financial Services and Markets Act 2000, a person must not communicate a financial promotion unless:

  1. They are an authorized person (FCA authorized), or
  2. The content is approved by an authorized person, or
  3. An exemption applies

For US-based platforms, this creates a significant barrier. I advise clients that simply making a website inaccessible to UK IP addresses is not sufficient. The FCA has taken action against firms for promotions that UK residents could potentially access.

Available Exemptions

⚠ Criminal Liability Warning

Breaching Section 21 is a criminal offense punishable by up to 2 years imprisonment. I cannot emphasize enough: the UK financial promotions regime requires careful legal analysis before any marketing activities that could reach UK persons.

Singapore and Hong Kong Restrictions

Asian financial centers have their own distinct regulatory approaches. In my practice, I find these jurisdictions often overlooked by US platforms, but enforcement has increased significantly.

🇸🇬 Singapore (MAS)

  • Capital Markets Services License: Required for dealing, advising, fund management
  • Accredited Investor Exemption: Net assets SGD 2M+ or income SGD 300K+
  • Institutional Investor Exemption: Banks, licensed entities, governments
  • No Reverse Solicitation: MAS does not recognize this concept

🇭🇰 Hong Kong (SFC)

  • Type 1-10 Licenses: Specific licenses for each regulated activity
  • Professional Investor Definition: HKD 8M+ portfolio or institutional
  • Active Marketing Test: SFC focuses on active solicitation in HK
  • OFC Regime: Open-ended Fund Company structure for funds

Singapore: The Accredited Investor Path

When I advise clients on Singapore market access without full licensing, the accredited investor exemption under Section 275 of the Securities and Futures Act is typically the most viable path. Requirements:

Hong Kong: Professional Investor Only

The SFC's approach focuses on whether you are "actively marketing" in Hong Kong. I advise clients that the following activities likely constitute active marketing:

Safe Harbor Approaches for International Marketing

After years of advising trading platforms on international expansion, I have developed a framework of relatively safe approaches that minimize regulatory risk while allowing controlled international growth.

Tier 1: Lowest Risk Approaches

Tier 2: Moderate Risk with Proper Structure

Tier 3: Higher Risk (Requires Significant Legal Resources)

✅ My Recommended Approach

For most US-based trading platforms in growth stage, I recommend starting with strict geo-blocking of high-risk jurisdictions (EU, UK, Singapore, Hong Kong, Australia) and a professional/institutional investor only policy for others. Expand into specific jurisdictions only after obtaining proper local legal advice and establishing compliance infrastructure.

Common Mistakes That Trigger Regulatory Issues

In my practice, I have seen the same mistakes repeatedly lead to regulatory problems. Here are the most common issues I advise clients to avoid:

1. The "Accidental Marketing" Problem

Platforms often trigger regulatory issues through activities they don't recognize as marketing:

2. Inadequate Onboarding Controls

Simply asking users their country of residence is insufficient. I have seen enforcement actions where regulators noted:

3. The "We're Just Technology" Fallacy

Many platforms believe they can avoid financial regulation by characterizing themselves as pure technology providers. This fails when:

⚠ The Affiliate Marketing Trap

Using local affiliates or influencers to market your platform can be worse than direct marketing. You become responsible for their compliance failures, and regulators view this as an attempt to circumvent local marketing rules. I advise clients to carefully vet and contractually bind any marketing partners.

4. Inconsistent Geographic Policies

Regulators look for inconsistencies that suggest marketing restrictions are not genuine:

5. Relying on Terms of Service Alone

Placing restrictions in Terms of Service without enforcing them provides no regulatory protection. I have reviewed enforcement actions where regulators explicitly noted that TOS restrictions were meaningless because:

Practical Compliance Checklist

Cross-Border Marketing Compliance Checklist

  • Jurisdiction Mapping: Document which countries you will and will not serve, with legal basis for each decision
  • Geo-Blocking Implementation: Technical controls blocking access from prohibited jurisdictions (IP-based minimum)
  • Onboarding Verification: Document verification for country of residence, not just self-certification
  • Investor Classification: Robust process for verifying professional/accredited investor status where relied upon
  • Marketing Review Process: Legal review of all marketing materials before publication
  • Social Media Policy: Guidelines for employees and contractors on international posting
  • Reverse Solicitation Documentation: If relying on reverse solicitation, timestamped records of unsolicited client contact
  • Periodic Re-verification: Annual or transaction-based re-verification of client residence and status
  • Website Disclosures: Clear statements about service availability and geographic restrictions
  • Local Counsel Network: Relationships with lawyers in key target jurisdictions for ongoing advice
  • Regulatory Monitoring: Process for tracking regulatory changes in jurisdictions you serve
  • Incident Response Plan: Procedure for responding to regulatory inquiries from foreign authorities
  • Affiliate/Partner Compliance: Contractual requirements and oversight for any marketing partners
  • Record Retention: Maintain all marketing materials and client communications per jurisdictional requirements

Putting This Into Practice

Cross-border marketing compliance is not a one-time exercise. I advise clients to treat this as an ongoing program requiring:

  1. Initial Assessment: Map your current exposure and create a jurisdiction-by-jurisdiction compliance plan
  2. Technical Implementation: Deploy robust geo-blocking and client verification systems
  3. Policy Documentation: Create written policies covering all aspects of international marketing
  4. Training: Ensure all team members understand geographic restrictions
  5. Ongoing Monitoring: Regular review of marketing activities and regulatory developments
  6. Periodic Audit: Annual third-party review of cross-border compliance

💡 When to Seek Local Counsel

I always advise clients to engage local counsel before entering any new jurisdiction. The cost of proper legal advice upfront is a fraction of the cost of regulatory enforcement. Key triggers for seeking local advice: receiving any inquiry from a foreign regulator, planning to actively market in a new jurisdiction, or receiving significant organic traffic from a new market.
