The global cryptocurrency market continues to evolve rapidly, with over-the-counter (OTC) trading playing an increasingly vital role—especially for institutional investors and high-net-worth individuals. While centralized exchanges (CEX) reported a staggering $4.29 trillion in trading volume during Q1 2024, OTC markets remain less visible due to their private, customized nature. Despite limited public data, the OTC sector is expanding in parallel with overall market growth.
Understanding the regulatory frameworks governing OTC trading in key financial hubs—Hong Kong, Singapore, and the United States—is essential for compliance, risk management, and strategic planning.
OTC Trading vs. Exchange Trading: Key Differences
Before diving into regional regulations, it’s important to understand how OTC trading differs from traditional exchange-based trading.
Over-the-Counter (OTC) Trading
OTC trading involves direct transactions between two parties, often facilitated by brokers or OTC desks, without using a centralized order book. This model offers several advantages:
- Large transaction capacity: Enables execution of substantial trades with minimal market impact.
- Price stability: Pre-negotiated prices reduce slippage, especially critical for large orders.
- Privacy and anonymity: Transactions are not publicly recorded, appealing to institutions seeking discretion.
- Flexibility: Customizable terms, settlement methods, and trade sizes.
However, OTC trading comes with notable risks:
- Counterparty risk: Reliance on the credibility of counterparties and intermediaries.
- Limited regulation: Less oversight compared to regulated exchanges.
- Security dependence: Safety hinges on the reputation and internal controls of OTC providers.
As such, OTC is primarily used by institutional players and wealthy individuals managing significant crypto holdings.

Exchange-Based Trading
In contrast, exchange trading occurs on centralized platforms that match buy and sell orders via order books. Key benefits include:
- High liquidity: Access to deep markets across numerous assets.
- Transparency: All trades are recorded and visible on-chain or on-platform.
- Lower counterparty risk: Centralized entities act as intermediaries and custodians.
- User-friendly interfaces: Advanced tools like analytics, bots, and real-time data enhance usability.
Challenges include:
- Price slippage on large orders.
- Regulatory restrictions in certain jurisdictions.
- KYC/AML requirements that compromise privacy.
- Fees that can accumulate over time.
Exchange trading suits retail investors and traders prioritizing convenience and accessibility.
Regulatory Landscape: Hong Kong, Singapore, and the US Compared
Each jurisdiction approaches cryptocurrency regulation differently, reflecting unique economic priorities and legal traditions.
Hong Kong: Building a Regulated Crypto Hub
Hong Kong’s Securities and Futures Commission (SFC) oversees virtual asset activities under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance (AMLO). Virtual Asset Trading Platforms (VATPs) must obtain licenses and adhere to strict compliance standards.
A significant development emerged in February 2024 when the Financial Services and Treasury Bureau (FSTB) launched a public consultation proposing a licensing regime for OTC virtual asset service providers. Key points include:
- OTC operators must apply for a two-year license through Hong Kong Customs.
- Only virtual assets listed on SFC-approved platforms can be traded.
- Retail investors cannot access assets unavailable on licensed exchanges or non-HKMA-approved stablecoins (professional investors are exempt).
- Physical OTC businesses must operate from approved premises; online operators need local management offices and record storage.
- Mandatory appointment of qualified compliance and AML officers.
- Full transaction record-keeping and wallet disclosure requirements.
Existing OTC businesses will have a six-month transition period, during which they must submit applications within the first three months to continue operations.
This initiative aims to close regulatory gaps, particularly concerning unlicensed cash-based crypto kiosks, while enhancing investor protection and anti-illicit finance measures.
Singapore: Clarity Through the Payment Services Act
Singapore’s Monetary Authority of Singapore (MAS) regulates crypto activities under the Payment Services Act (PSA). Any platform facilitating OTC trades may be classified as a Digital Payment Token (DPT) service provider and require licensing.
Two main license types apply:
- Standard Payment Institution License: For firms processing up to SGD 3 million in monthly average crypto transactions.
- Major Payment Institution License: For larger operations without transaction caps.
Under PSA, regulated activities include:
- Buying/selling cryptocurrencies
- Operating exchanges
- Transferring digital tokens
- Referring users to crypto services
All licensees must implement robust AML/CFT procedures, conduct customer due diligence, and monitor transactions continuously.
Recent MAS guidance emphasizes stricter custody rules and operational resilience. While the approval process is rigorous, Singapore’s balanced approach—combining strong oversight with innovation support—makes it a top destination for compliant fintech firms.

United States: Fragmented but Evolving Oversight
The U.S. lacks a unified crypto regulator. Instead, oversight is shared among multiple agencies:
- FinCEN: Requires all crypto businesses to register as Money Services Businesses (MSBs), enforce KYC/AML protocols, and file Suspicious Activity Reports (SARs).
- SEC: Regulates tokens deemed securities under federal law, mandating registration and disclosure.
- CFTC: Treats Bitcoin and Ethereum as commodities; oversees futures markets and related derivatives.
- OCC: Provides guidance on bank involvement in crypto custody and payments.
A major upcoming change is California’s Digital Financial Assets Law (DFAL), set to take effect July 1, 2025. Similar to New York’s BitLicense, DFAL will require companies engaged in digital asset exchanges, issuance, or custody to obtain a state license from the Department of Financial Protection and Innovation (DFPI).
Covered activities include:
- Exchanging or issuing digital financial assets
- Holding electronic precious metals
- Trading game tokens for real-world value
With California joining New York and Louisiana in establishing dedicated crypto licensing regimes, federal harmonization remains a challenge. However, the trend points toward increasing regulatory clarity and enforcement.
Future Outlook: Which Market Is Most OTC-Friendly?
Hong Kong: On the Path to Institutional Legitimacy
Hong Kong’s proactive stance—particularly its proposed OTC licensing framework—signals its ambition to become Asia’s premier regulated crypto hub. By aligning with international AML standards and protecting retail investors, Hong Kong enhances market integrity. Though initial compliance burdens may deter some operators, long-term benefits include greater institutional trust and cross-border capital inflows.
Singapore: Stability Meets Innovation
Singapore stands out for its clear, principles-based regulation. MAS’s consistent enforcement and support for financial technology innovation create a favorable environment for compliant OTC desks. The country’s reputation for rule of law and financial stability further boosts confidence among global players.
United States: Depth Despite Complexity
Despite regulatory fragmentation, the U.S. remains attractive due to its deep capital markets, advanced infrastructure, and technological leadership. Once compliance hurdles are cleared—such as MSB registration or state-level licensing—firms gain access to one of the world’s most sophisticated investor bases.
While uncertainty persists around asset classification (security vs. commodity), growing enforcement actions suggest regulators are tightening control. For well-resourced institutions capable of navigating this landscape, the U.S. offers unmatched scale and opportunity.
