LEI is no longer limited to financial institutions
Most companies initially assume that the LEI code only applies to banks or large financial institutions. However, this perception is outdated. Over the past decade, the role of LEI has expanded significantly across multiple sectors and jurisdictions.
Today, companies encounter LEI requirements when they move into more advanced financial activities. For example, this includes investing in markets, applying for financing, making cross-border payments, participating in regulated environments, or interacting with financial institutions.
By 2026, LEI clearly forms part of global financial infrastructure. In some countries, it is already deeply embedded into regulatory frameworks. In others, its adoption is accelerating as part of broader digitalization and transparency initiatives. As a result, the need for an LEI depends primarily on business activity rather than company size or industry alone.
What is an LEI code?
The Legal Entity Identifier (LEI) is a 20-character alphanumeric code that uniquely identifies legal entities participating in financial transactions. In practice, it connects a company to verified reference data, including its official name, legal address, and ownership structure, as defined by the Global Legal Entity Identifier Foundation (GLEIF).
If you are new to the concept, you can learn what an LEI code is.
Financial institutions, regulators, and data systems rely on LEI to identify counterparties in a consistent and standardized way. Therefore, LEI significantly improves transparency across markets and reduces ambiguity in financial reporting.
In addition, LEI helps regulators monitor systemic risk, supports data aggregation, and improves the quality of financial datasets. Because of this, LEI adoption has expanded steadily across markets, reporting systems, and payment infrastructures.
When does an LEI become necessary in practice?
Companies rarely obtain an LEI in isolation. Instead, the need typically arises when a business activity requires it.
In practice, companies often discover the need for an LEI when a transaction cannot be completed or a process cannot move forward without it. Therefore, understanding real-world use cases is the most practical way to assess its relevance.
Investing or trading in financial markets
In the European Union, companies must use an LEI when trading financial instruments such as shares, bonds, or derivatives. Without an LEI, financial institutions are not allowed to execute transactions on behalf of the company, as required under frameworks supervised by the European Securities and Markets Authority (ESMA).
To start the process, you can register an LEI quickly online.
The United Kingdom follows a similar approach. Market participation depends on proper identification, and LEI plays a central role in transaction reporting.
Canada and Australia also use LEI within their financial reporting and trading frameworks. As a result, LEI supports market infrastructure globally, not only within Europe.
Using derivatives for hedging or trading
Derivatives markets require precise identification of all counterparties. Because of this, LEI is one of the most widely used identifiers in this area.
The EU and UK embed LEI into derivatives reporting frameworks. Meanwhile, in the United States, systems connected to the U.S. Securities and Exchange Commission (SEC) and Commodity Futures Trading Commission (CFTC) rely on LEI for data collection and oversight. If your company already has an LEI, you can renew your LEI before it expires.
Similarly, the same pattern appears in Singapore, Hong Kong, India, Canada, Australia, Mexico, and South Africa. Therefore, even non-financial companies may need an LEI if they use derivatives for hedging or risk management.
Applying for large-scale financing
Some jurisdictions link LEI directly to lending frameworks. India is one of the clearest examples of this approach.
Banks may require an LEI when companies apply for large loans, as outlined by the Reserve Bank of India (RBI). As a result, LEI becomes a practical requirement that directly affects access to financing.
Over time, as financial institutions standardize risk assessment and reporting processes, similar expectations may emerge in additional markets.
Processing large or cross-border payments
Payment systems are evolving toward structured and standardized data. Consequently, LEI is becoming increasingly relevant in this area.
In the United Kingdom, CHAPS payments incorporate enhanced data aligned with ISO 20022 standards. LEI supports this structure by enabling clear identification of entities involved in transactions, as promoted by SWIFT.
India uses LEI in large-value payment systems, while China integrates LEI into cross-border payment infrastructure such as CIPS. Therefore, companies engaged in international business or high-value transactions may encounter LEI requirements in payment processes.
Before initiating payments, it is useful to check your LEI status in the global database.
Operating in insurance and pension frameworks
Insurance and pension sectors rely heavily on structured reporting and supervision. Because of this, consistent entity identification is essential.
In the European Union, LEI is used within supervisory frameworks for insurance and pension systems. India also applies LEI in regulatory contexts related to insurance.
Companies operating in these sectors may require an LEI to meet reporting and compliance obligations.
Meeting financial reporting obligations
In many cases, LEI becomes relevant through reporting rather than direct transactions.
Within the European Union, multiple frameworks covering banks, investment firms, and payment institutions require LEI in reporting processes. Similarly, in the United States, LEI appears in various financial data collection systems.
Australia and the United Kingdom also use LEI in supervisory reporting structures. Therefore, companies operating in regulated environments often need an LEI regardless of whether they actively trade in financial markets.
Participating in bond and credit markets
Credit markets depend on reliable and standardized identification systems. As a result, LEI plays a key role in this environment.
China uses LEI in bond issuance and credit market infrastructure. In addition, other jurisdictions apply similar approaches in structured finance and capital market activities.
Companies entering capital markets may need an LEI to ensure smooth participation and compliance. Understanding pricing is also important, so you can see LEI registration and renewal costs.
Operating across multiple jurisdictions
International operations significantly increase the likelihood of encountering LEI requirements.
For example, Hong Kong links LEI to investor identification regimes. Turkey integrates LEI into securities infrastructure. Saudi Arabia has highlighted the importance of obtaining LEI through accredited providers. Meanwhile, China and India incorporate LEI into cross-border financial systems.
Therefore, for internationally active companies, LEI often becomes a standard expectation rather than an optional element.
Why regulators and financial systems rely on LEI
To fully understand LEI adoption, it is important to look at the underlying reasons behind it.
Regulators require consistent identifiers to monitor financial markets, detect risks, and aggregate data across institutions. Without a standardized identifier, comparing and linking data becomes inefficient and error-prone.
LEI solves this problem by providing a global, open, and standardized identification system. As a result, it improves data quality, enhances transparency, and supports regulatory oversight, as highlighted by the Financial Stability Board (FSB).
In addition, LEI enables better interoperability between systems. This becomes increasingly important as financial services move toward digital and cross-border environments, a trend also discussed by the Bank for International Settlements (BIS).
How LEI has spread globally
LEI adoption does not depend on a single regulation or region. Instead, it has expanded across multiple layers of the financial system.
Markets, payment systems, reporting frameworks, and digital identity initiatives all contribute to its growth. Consequently, LEI is now used in both advanced and emerging financial ecosystems.
Japan – established financial systems
Japan uses LEI within reporting and derivatives frameworks under the Financial Instruments and Exchange Act, supervised by the Financial Services Agency of Japan (FSA). This confirms its role in highly developed markets.
South Korea – modern investor identification
South Korea applies global identification standards for foreign investors. LEI fits into this broader shift toward international data consistency.
Mexico and Latin America – regulatory integration
Mexico uses LEI in derivatives and reporting frameworks. Argentina and Brazil show similar developments in financial regulation.
South Africa – derivatives reporting
South Africa requires LEI in certain derivatives reporting frameworks, demonstrating adoption beyond major Western economies.
Turkey – securities infrastructure
Turkey links LEI with ISIN and securities infrastructure, supporting consistent identification across financial systems.
Thailand and Malaysia – financial market usage
Thailand connects LEI to bond market participation, while Malaysia uses it in financial and payment-related frameworks.
Saudi Arabia – regulatory direction
Authorities emphasize the importance of LEI adoption, signaling continued integration into financial systems.
Singapore and Hong Kong – international hubs
Both jurisdictions use LEI in derivatives reporting and investor identification, reinforcing its role in global finance.
Canada and Australia – structured frameworks
Both countries apply LEI in derivatives reporting and supervisory systems, reflecting strong regulatory alignment.
United States – data-driven financial system
The United States uses LEI across multiple reporting frameworks, including derivatives, investment funds, and financial data systems.
European Union – the widest integration
The European Union demonstrates the most comprehensive LEI integration. It spans investment, derivatives, banking, insurance, payments, crypto-assets, and digital identity.
Recent developments such as MiCA, DORA, SEPA enhancements, and European Digital Identity initiatives continue to expand its role.
Is LEI mandatory everywhere?
LEI is not universally mandatory for all companies. However, its importance continues to increase.
Some regulations require it explicitly. Others request or recommend it depending on the context. In practice, companies often treat LEI as necessary when systems, banks, or platforms depend on it.
The global direction: LEI as a standard identifier
A clear global pattern has emerged.
LEI does not spread through a single regulation. Instead, it becomes embedded into financial infrastructure. Over time, it transitions from optional to expected, and in many cases, effectively required.
When might an LEI not be needed?
Some companies can operate without an LEI, particularly those with purely local activities.
Businesses that do not interact with financial markets, do not use complex financing, and do not engage in cross-border transactions may not need an LEI.
However, this situation can change quickly as the company grows or expands internationally.
How to assess if your company needs an LEI
To evaluate this, consider the following:
- Does your company invest in financial instruments?
- Does it use derivatives?
- Does it apply for large financing?
- Does it process cross-border payments?
- Does it operate in a regulated sector?
- Does it have reporting obligations?
- Does it work with international financial institutions?
If the answer to any of these is yes, then LEI is likely already relevant or will become relevant soon.
Conclusion
The question is no longer simple.
Some companies must obtain an LEI due to regulation. Others need it because financial systems require it. In both cases, the practical outcome is the same.
The European Union shows the deepest integration. The United Kingdom connects LEI to both markets and payments. The United States uses it extensively in reporting systems. India applies it in lending and payment frameworks.
At the same time, countries such as Japan, China, Canada, Australia, Hong Kong, Singapore, Mexico, Turkey, Malaysia, and South Africa use LEI in specific financial contexts.
Ultimately, LEI has become a global standard for identifying companies.
For many businesses, the real question is not whether they need an LEI today, but when they will need it. If you already know you need one, you can apply for your LEI in minutes.
