LBMA and the Global Precious Metal Market Explained

The London Bullion Market Association (LBMA) is the global authority for the wholesale over-the-counter (OTC) market for precious metals. Headquartered in London, the LBMA plays a pivotal role in the international trade of gold, silver, platinum, and palladium, setting the standards that ensure integrity, quality, and trust in the marketplace.

Often regarded as the heartbeat of global bullion trade, the LBMA isn’t just a regulatory body—it’s a foundation for how metals are mined, refined, traded, and stored across borders. From central banks and sovereign wealth funds to refiners, mints, and institutional investors, nearly every major player in the industry operates in alignment with LBMA protocols and benchmarks.

At its core, the LBMA is a standard-setter and enforcer, ensuring that all market participants adhere to strict guidelines related to:

• Metal quality and purity through the Good Delivery List
• Responsible sourcing and ESG compliance
• Trade transparency and anti-money laundering standards
• Market-making and price-setting mechanisms

By maintaining globally accepted norms, the LBMA fosters market confidence, enabling precious metals to function as reliable stores of value and transactional assets.

Though headquartered in the UK, the LBMA's reach is global. Its pricing mechanisms—like the London Gold and Silver Fixes—serve as benchmarks used in:

• Physical bullion trades
• ETF valuations
• Central bank reserve assessments
• Derivatives and futures pricing models

The LBMA also collaborates with international regulators and exchanges (e.g., CME Group, LME, ICE), reinforcing its central role in the seamless functioning of global precious metal markets.

The Core Functions of the LBMA

The London Bullion Market Association (LBMA) is not merely an industry trade group—it is a structural pillar of the global precious metals ecosystem. Through its governance, the LBMA ensures that gold, silver, platinum, and palladium markets operate with integrity, efficiency, and transparency. Below are the four key functions that define its critical role in the global bullion trade.

1. Setting Global OTC Market Standards

The LBMA provides the regulatory and operational framework for the over-the-counter (OTC) market, where the majority of global gold and silver trades occur. Unlike centralized exchanges, OTC trades are conducted directly between parties, making standardization essential for trust and efficiency.

LBMA standards govern:

1. Settlement conventions and trade documentation
2. Clearing processes through the LPMCL (London Precious Metals Clearing Limited)
3. Guidelines for good market practice, including bilateral trading and risk management

These standards ensure that institutional participants—such as central banks, bullion banks, and refiners—operate within a consistent and trusted structure.

The LBMA offers detailed manuals and guidance on:

• Allocated vs. unallocated gold settlement
• Physical delivery logistics and vaulting standards
• Legal compliance and contractual best practices

This helps minimize counterparty risk and enhance operational transparency across borders and institutions.

2. Custodian of the London Good Delivery List

The London Good Delivery List is the global benchmark for gold and silver bar quality. Maintained and enforced by the LBMA, it certifies refiners who meet strict criteria for:

• Metal purity (minimum 995 for gold, 999 for silver)
• Bar dimensions, weight tolerances, and markings
• Proven production capacity and responsible sourcing standards

Only refiners on this list can deliver into the London bullion market, making the Good Delivery List the de facto passport for global precious metal acceptance.

The Good Delivery designation is recognized by:

• Major exchanges (COMEX, SGE, TOCOM)
• Sovereign mints and treasuries
• ETFs and institutional asset managers

It ensures that the bars traded are authentic, consistent, and globally trusted, reducing risks in international settlement and physical delivery.

3. Promoting Compliance and Ethical Standards

The LBMA leads the industry in responsible sourcing practices, requiring Good Delivery refiners to comply with its Responsible Gold Guidance, which aligns with:

• OECD Due Diligence Guidelines
• UN Guiding Principles on Business and Human Rights
• ESG metrics for ethical labor, environmental care, and conflict-free sourcing

Refiners undergo annual independent audits to verify compliance, helping the LBMA promote transparency and sustainability in the supply chain.

LBMA members must also enforce robust AML frameworks, including:

• Know Your Customer (KYC) protocols
• Beneficial ownership disclosures
• Suspicious transaction reporting mechanisms

This minimizes the risk of illicit gold flows, enhances regulatory compliance, and ensures the London market remains clean and credible.

4. Price Benchmarking and Market Reporting

The LBMA is responsible for the London Gold and Silver Price Fixes, which are set twice daily via an auction process run by ICE Benchmark Administration (IBA). These benchmarks are:

• Used globally in contracts, settlement, and derivatives pricing
• Referenced by ETFs, mining companies, and central banks
• Critical for establishing fair value in the absence of exchange-traded price discovery

To enhance market transparency, the LBMA publishes:

• Monthly vault holdings data (gold and silver ounces held in London vaults)
• Trade volume statistics, broken down by metal, region, and transaction type
• Responsible sourcing and audit reports

These disclosures offer insights into market liquidity, investor behavior, and underlying bullion demand trends, reinforcing trust in the London market’s integrity.

This blog explores the LBMA's structure, standards, pricing systems, and its irreplaceable position in driving efficiency, security, and consistency in the global bullion industry.

Historical Evolution of the LBMA

The London Bullion Market Association (LBMA) has evolved from a domestic supervisory body to a globally respected authority in precious metals. Its development reflects both the maturation of the gold and silver markets and the growing need for standardization, transparency, and responsible practices in an increasingly globalized economy.

Origin from the Bank of England’s Market Supervision Role

Before the LBMA was formally established, the Bank of England played the role of de facto regulator for the London bullion market. It supervised the operations of major gold dealers, set standards for refining and vaulting, and ensured orderly trade settlement in what was then a relatively insular and opaque market.

However, as the gold market liberalized post-Bretton Woods and London emerged as a global hub for bullion trade, there was a growing need for an independent, industry-led body to formalize standards and governance across all market participants.

Establishment as an Independent Industry Authority in 1987

The LBMA was officially founded in 1987 with the endorsement of the Bank of England. From its inception, the association aimed to:

• Standardize OTC bullion trade practices
• Maintain and expand the Good Delivery List for gold and silver bars
• Act as a neutral intermediary for setting benchmark prices and trade conventions

This marked a turning point in the modernization of global bullion markets, as the LBMA quickly became the central institution overseeing quality, ethics, and reliability in gold and silver trading.

Key Milestones: Good Delivery Expansion, ESG Adoption, Global Outreach

Over the decades, the LBMA has hit several important milestones that shaped its global influence:

1990s – Internationalization of the Good Delivery List: Expansion of refinery accreditation to North America, Asia, and Australia, allowing for broader global participation in the London bullion market.

2004 – Launch of Responsible Gold Guidance: Pioneering ESG compliance in the industry, with a focus on conflict-free sourcing, anti-money laundering, and ethical labor practices.

2012 – Price Benchmark Reform: Transition from traditional telephone-based fixing to electronic auctions administered by IBA, improving transparency and auditability.

2017 – Global Precious Metals Code: Introduction of a best-practices code for conduct in the wholesale market, aligning with global financial integrity standards.

2020s – Vault Holdings and Transparency Initiatives: The LBMA began publishing monthly vault data, trade volume statistics, and environmental disclosures to foster greater accountability and market insight.

Each milestone reflects the LBMA’s shift from a London-centric entity to a global standard-bearer, influencing everything from central bank reserve policy to retail ETF pricing and ESG frameworks in mining.

The London Good Delivery System

The London Good Delivery System is the gold standard—literally—for the global physical bullion trade. Administered by the LBMA, it defines the technical, ethical, and operational criteria for gold and silver bars eligible for settlement in the London bullion market. Recognized worldwide, this system underpins trust in precious metal transactions by ensuring uniformity, authenticity, and quality.

1. Good Delivery Bars and Their Specifications

To qualify as "Good Delivery," bars must adhere to precise specifications:

Gold bars:

Weight: Approximately 400 troy ounces (12.4 kg)

Purity: Minimum 99.5% fine gold (995.0 parts per thousand)

Silver bars:

Weight: Approximately 1,000 troy ounces (31.1 kg)

Purity: Minimum 99.9% fine silver (999.0 parts per thousand)

These sizes are designed for institutional settlement, offering high value density and compatibility with secure vault systems.

Each bar must feature:

• The refiner’s official hallmark
• A unique serial number
• The year of manufacture
• Exact assayed weight
• Stamped purity

Only bars produced by LBMA-accredited refiners can be accepted as Good Delivery, ensuring global confidence in quality, traceability, and legitimacy.

2. Accreditation and Revalidation Process

To be added to the Good Delivery List, a refiner must undergo a rigorous accreditation process, including:

• Submission of sample bars for independent assay testing
• Evaluation of the refiner’s production facilities, output capacity, and process controls
• Review of the company’s financial health and compliance systems

The LBMA works with independent referees—highly trusted laboratories—to verify the refiner’s technical competence and product consistency.

Only after meeting these criteria is a refiner granted Good Delivery status—a designation that significantly enhances its global credibility.

Accreditation isn’t permanent. Refiners must meet ongoing compliance standards, including:

• Annual reports on responsible sourcing and ESG compliance
• Physical re-inspection or re-sampling when deemed necessary
• Regular updates on production capacity and operational changes

Failure to meet standards can result in suspension or removal from the Good Delivery List, which can drastically impact a refiner’s access to international markets.

This strict regime helps maintain the integrity and reliability of the physical bullion trade across borders and ensures that all LBMA-recognized gold and silver bars meet uniform global expectations.

Responsible Sourcing and Due Diligence Standards

In today’s bullion industry, traceability and ethical sourcing are as critical as metal purity. The LBMA has taken a leadership role in ensuring that all gold and silver traded through the London market is sourced responsibly, transparently, and in alignment with global ESG norms. Its Responsible Sourcing Programme (RSP) has become the global benchmark for ethical metal sourcing across the supply chain.

1. The Responsible Sourcing Programme

Launched in 2012, the Responsible Sourcing Programme (RSP) is a mandatory compliance initiative for all refiners on the LBMA’s Good Delivery List. It requires refiners to establish and maintain a robust ESG (Environmental, Social, Governance) framework for their sourcing operations.

Core requirements include:

• Supply chain due diligence to detect and prevent conflict minerals
• Environmental impact assessments of sourcing activities
• Labor rights and community welfare monitoring in mining regions
• Corruption and bribery risk mitigation

This system ensures that every ounce of gold or silver entering the LBMA pipeline is free from human rights abuses, environmental degradation, and financial crime exposure.

Refiners must implement the programme across all operations—regardless of where the metal is sourced—and are subject to:

• Annual third-party audits by LBMA-approved auditors
• Strict recordkeeping and evidence-based compliance
• Immediate corrective action if risks or violations are detected

Failure to comply can result in suspension from the Good Delivery List, making adherence non-negotiable for participation in the global market.

2. Program Expansion and Continuous Updates

The RSP is continuously evolving to reflect the complexities of global supply chains. In recent years, the LBMA has expanded its guidance to address:

Artisanal and small-scale mining (ASM): Balancing ethical sourcing from ASM communities with traceability and legal compliance

Conflict-affected and high-risk areas (CAHRAs): Enhanced due diligence protocols to prevent financing of armed conflict or terrorism

This ensures refiners are not only compliant, but also proactively managing emerging sourcing risks.

Each refiner must submit an annual Responsible Sourcing Report, detailing:

• Risk assessments and mitigation plans
• Results of third-party audits
• Any supply chain changes or red flags addressed during the year

Auditors must be approved by the LBMA, meet international standards (e.g., ISAE 3000), and be rotated periodically to maintain independence.

3. Alignment with Global Frameworks

The LBMA’s programme is designed to align with—and reinforce—leading global initiatives, including:

• The OECD Due Diligence Guidance for Responsible Supply Chains
• The UN Sustainable Development Goals (SDGs)
• The UN Guiding Principles on Business and Human Rights

This alignment ensures that LBMA-compliant refiners are not only meeting market expectations, but also contributing to global development, ethical trade, and sustainable resource use.

The result is a gold and silver market that operates with integrity, transparency, and accountability—from mine to vault.

The Global Precious Metals Code

The Global Precious Metals Code (GPMC), introduced by the LBMA in 2017, is a comprehensive set of principles and best practices designed to promote ethical conduct, market integrity, and operational transparency within the wholesale precious metals market. It serves as a unifying framework for participants around the world, aligning the industry with evolving regulatory expectations and stakeholder demands.

1. Scope and Objectives

The GPMC outlines conduct standards for all market participants involved in trading, clearing, vaulting, or settling precious metals—particularly in the OTC market. Its main objectives are to:

• Promote ethical behavior and professional integrity
• Encourage honest pricing, clear communication, and full disclosure
• Prevent manipulation, insider trading, and unfair competitive practices

Key focus areas include:

• Conflicts of interest and how to manage them
• Execution transparency in pricing and trade documentation
• Internal controls and governance structures within trading firms

In addition to operational standards, the Code integrates anti-corruption and fair trading policies to ensure:

• Anti-bribery practices in sourcing and contracting
• Confidentiality safeguards for clients and counterparties
• Clear rules for employee conduct and whistleblower protections

The GPMC is not just a set of ideals—it’s a functional, actionable guide that encourages market participants to behave responsibly, regardless of jurisdiction.

2. Enforcement and Compliance Mechanisms

All LBMA members are required to formally attest to their compliance with the Code. This includes:

• Full board-level endorsement of the Code’s principles
• Annual attestation letters confirming implementation
• Inclusion of Code adherence within internal compliance policies

For market participants outside the LBMA, adoption is strongly encouraged as a benchmark of credibility and operational integrity.

To uphold the Code, the LBMA maintains a compliance monitoring framework, which includes:

• Periodic audits and member self-assessments
• Investigative procedures for potential breaches or misconduct
• A formal disciplinary process that can result in warnings, suspension, or expulsion

This proactive enforcement structure ensures that adherence to the Code is more than symbolic—it’s institutionalized across the global precious metals trade.

Market Transparency and Data Initiatives

Transparency is a cornerstone of a well-functioning, trusted market. The LBMA has taken a leadership role in enhancing visibility into the global bullion ecosystem through robust data initiatives, standardized reporting, and independent price benchmarking. These efforts not only strengthen institutional confidence but also promote market efficiency, integrity, and accountability.

1. London Vault Holdings Reporting

The LBMA began publishing London Vault Holdings Reports in 2017 to provide greater transparency around physical gold and silver stored in LBMA-approved vaults. These monthly updates include:

• Total ounces of gold and silver held across all London vaults
• Breakdown by metal type (allocated and unallocated)
• Changes in inventory from prior periods

This initiative gives the market a clear picture of bullion liquidity, serving as a confidence metric for both institutional and retail participants.

By disclosing aggregate holdings data, the LBMA:

• Reduces uncertainty about the availability of physical metal
• Helps investors assess storage capacity, market depth, and delivery readiness
• Reinforces London’s position as a secure and credible bullion hub

This data is widely cited by central banks, ETF providers, and analysts for modeling supply-demand dynamics.

2. Trade Reporting

To further enhance market clarity, the LBMA introduced daily OTC trade reporting, capturing data from LBMA members and authorized market-makers.

Key features:

• Reporting of gold, silver, platinum, and palladium trades
• Data includes trade volumes, turnover, transaction type (spot, swap, forward)
• Aggregated anonymously and released in the LBMA Trade Data Transparency Report

This dataset allows for:

• Accurate volume analysis of wholesale market activity
• Trend identification in liquidity flows and dealer behavior
• Benchmarking for risk management and regulatory oversight

Researchers, economists, and institutions use this data to:

• Evaluate the size and activity of the London bullion market
• Correlate trade volume with price volatility and macro events
• Compare OTC data with exchange-traded volumes (e.g., COMEX, Shanghai)

It provides a crucial window into the otherwise opaque OTC market, aligning bullion trading with standards seen in modern financial markets.

3. Precious Metals Prices Limited (PMPL)

Precious Metals Prices Limited (PMPL) is a subsidiary of the LBMA established to oversee the administration and licensing of official benchmark prices, namely:

1. The LBMA Gold Price
2. The LBMA Silver Price

These benchmarks are published twice daily (a.m. and p.m.) and serve as reference prices for contracts, ETFs, central bank transactions, and settlement procedures.

In partnership with ICE Benchmark Administration (IBA), PMPL ensures:

• Electronic auction-based price discovery
• Full compliance with IOSCO Principles for Financial Benchmarks
• A transparent, auditable, and regulated price-setting process

This model replaced the older, opaque “London Fix” system, reinforcing the LBMA’s commitment to transparency, modernization, and accountability in global price formation.

LBMA’s Influence on the Global Precious Metals Market

The London Bullion Market Association (LBMA) is more than a London-based institution—it is the anchor of trust, integrity, and standardization for the entire global precious metals supply chain. From mine to market, vault to ETF, the LBMA’s frameworks and governance systems shape how bullion is refined, traded, valued, and regulated around the world.
