Securities lending is a significant component of modern financial markets and how the global economy works. It can provide liquidity and support market efficiency under typical conditions. In this guide, we will delve into the landscape of securities lending in the UK. To ensure the accuracy and depth of our analysis, we have used research from various reputable sources, such as the leading non-profit International Securities Lending Association (ISLA).  

The article aims to offer a balanced view of the role of securities lending in today’s financial markets and its key concepts, such as collateralisation, indemnification, and Securities Lending Agreements (SLAs). This article will provide some insights into the securities lending landscape in the UK.

Market Participants and Their Roles 

Securities lending is the process of providing short-term loans of assets (stocks, bonds, etc). If a large financial company wants to temporarily borrow a stock or bond, it needs to find a counterparty willing to do that and will need to pay a fee and provide collateral.  

Therefore, the securities lending market in the UK comprises a wide range of participants, who each play a vital role in ensuring the smooth functioning of the market. Understanding these roles is crucial to understanding how securities lending contributes to overall market efficiency and liquidity. 

Pension Funds 

Pension funds are among the largest players in the securities lending market. As they tend to have long-term investment time horizons, pension funds often lend securities to generate additional income. This lending activity may help generate additional income on portfolios without selling the underlying assets, though returns are not guaranteed and depend on various market factors. 

Securities is a term that is used to represent the different types of tradable financial instruments. The term can refer to equities, such as stocks and shares, derivatives, such as futures and options, and, lastly, debt securities, such as bonds. 

One of the main reasons pension funds lend out securities is to try to earn extra revenue through lending fees. This can potentially contribute to overall portfolio performance, depending on lending conditions and market circumstances. The lending can also help pension funds run more efficiently as they can earn from idle assets that may not be generating capital growth. 

However, while the income benefits are attractive, pension funds must be very careful in managing the process as they are heavily regulated and have a duty of care to their investors. This is why pension funds focus on enacting strong risk management frameworks and adherence to regulatory guidelines.

Asset Managers 

Asset managers are responsible for overseeing investments on behalf of institutional and individual clients. They can use securities lending as a tool to improve portfolio returns and manage liquidity for their own accounts and client accounts.  

As asset managers are actively involved in the securities lending market, they help to contribute to market liquidity and efficiency. Securities which have higher liquidity can be bought or sold more quickly, as there is a higher number of buyers and sellers available. 

Securities lending has a different risk profile than traditional assets. Therefore, asset managers must communicate to their investors how it fits into their overall investment strategy 

For example, the world’s largest asset manager BlackRock, has its own internal securities lending operation. As of June 2014, for funds domiciled in the UK, 62.5% of all the revenue from securities lending is paid directly into the fund. BlackRock receives 37.5% compensation to cover its operational costs.

Hedge Funds 

Hedge funds are highly active in the securities lending market due to their flexible investment strategies and focus on generating high returns. A fund is a pooled investment vehicle. It takes on investor capital and charges a performance fee on any investment gains and a management fee regardless of performance.  

A mutual fund is often limited in its investment options to either purchasing equities or bonds. However, a hedge fund frequently uses other investment products such as leverage, derivatives, short-selling and options strategies. These types of funds are generally restricted to institutional or high-net-worth investors due to their complexity and risk profile. 

Hedge funds are prominent in short-selling and arbitrage strategies. As this involves borrowing securities, hedge funds are one of the most active participants in the securities lending industry, helping to provide liquidity and market efficiency.  

Interactions Between Participants 

The dynamic relationship between pension funds, asset managers, and hedge funds is central to the securities lending market. Pension funds and asset managers typically act as lenders, seeking to earn extra income from their long-term holdings.  

In contrast, hedge funds are primarily borrowers, utilising the borrowed securities for short-selling, arbitrage or hedging strategies. This relationship tends to support market liquidity and may contribute to broader market stability under normal conditions. While the activities are heavily regulated, authorities can sometimes miss the participants who are not engaged in proper risk management.  

For example, the collapse of Lehman Brothers in 2008 was due to its excessive leverage and exposure to bad loans. It used securities lending to raise cash but then used its collateral on risky assets. Its aggressive collateralised borrowing and lending operations caused a liquidity crunch, loss of confidence and bankruptcy. 

Key Concepts and Instruments in Securities Lending 

To fully understand securities lending, it’s essential to grasp some of the key concepts that underpin the market. These concepts help to define the mechanics of lending transactions and provide insight into how risks are managed and returns are generated. 

Collateralisation 

Collateralisation is a fundamental concept in securities lending. It involves the borrower providing collateral - often in the form of cash or other securities - to the lender as a guarantee against default. It helps to mitigate - but does not eliminate - the risk that the borrower will default on the transaction. If a default occurs, the lender can use the collateral to offset potential losses. 

The value of the collateral is regularly assessed, and a “haircut” is applied. A haircut is a percentage discount applied to the collateral’s market value, ensuring that the collateral’s value exceeds that of the lent securities. 

Collateral can take various forms, including cash, government bonds, or other high-quality securities. The choice of collateral often depends on the borrower’s profile, the lender’s risk tolerance, and regulatory requirements.

Indemnification 

Indemnification is another crucial concept of securities lending. It ensures that one party is compensated for any losses incurred due to the other party’s actions or omissions. In securities lending, indemnification provisions are included in the Securities Lending Agreement (SLA). 

An indemnification provision transfers certain risks from the lender to the borrower. This means that if the borrower fails to return the securities or causes a loss, they are responsible for compensating the lender. 

Clearly defined indemnification terms within the SLA ensure that both parties understand their obligations and the circumstances under which indemnification applies. This clarity helps prevent disputes and facilitates smoother transaction settlements.

Securities Lending Agreements (SLAs) 

The Securities Lending Agreement (SLA) is the contractual document that governs the terms of a securities lending transaction. It outlines the rights and obligations of both the lender and the borrower and serves as the legal foundation for the lending arrangement. 

Key Components of an SLA 

  • Transaction Terms: The SLA details the duration of the loan, the lending fee, and any other terms related to the transaction.
  • Collateral Requirements: It specifies the types of collateral acceptable, the valuation methodologies and the frequency of revaluations.
  • Indemnification Clauses: This includes specific indemnification provisions that protect the lender from potential losses.
  • Termination Conditions: The agreement outlines the conditions under which the lending arrangement can be terminated, either by mutual consent or due to breach of contract.
  • Governing Law: The SLA typically specifies the legal jurisdiction that governs the contract, ensuring that any disputes are resolved under a recognised legal framework. 

Conclusion 

Securities lending in the UK is a multifaceted investment area typically used by pension funds, asset managers and hedge funds. The transactions between these players help to create more liquidity and efficiency in the market. In turn, this can help retail traders to also transact in some of the securities being lent and borrowed, such as stocks.
