What is securitisation?

Introduction

Securitisation is one of the most important — and most misunderstood — mechanisms in modern finance. It underpins trillions of dollars of investment products globally, from mortgage-backed securities to auto loan ABS. Yet for many retail investors and wealth managers, the word still triggers more confusion than clarity.

This guide demystifies securitisation: what it is, how it works, why it exists, and — importantly — how advances in financial technology are making securitisation relevant for a much broader range of investment strategies and participants than ever before.

What Is Securitisation?

Securitisation is the process of converting illiquid assets or cash flows into tradeable securities.

At its most fundamental, securitisation takes a pool of assets — loans, receivables, revenue streams, or any other predictable cash flow — and packages them into a financial instrument that can be issued to investors. Those investors then receive the cash flows generated by the underlying assets, typically in the form of regular payments (interest, principal, or both) or a defined return at maturity.

The result is a security: a standardised, transferable financial instrument backed by real economic activity.

A Simple Example

A bank holds a portfolio of 500 residential mortgages. Each mortgage generates monthly repayments from homeowners. The bank packages these mortgages into a special legal vehicle, which then issues bonds to investors. Investors buy the bonds and receive regular payments funded by the homeowners’ mortgage repayments.

The bank has converted illiquid mortgage loans (which it cannot easily sell) into tradeable bonds. Investors have gained exposure to a diversified portfolio of mortgages with a defined return profile. This is securitisation.

Why Does Securitisation Exist?

For originators (banks, companies, asset managers):

• Converts illiquid assets into liquid capital that can be redeployed
• Transfers credit risk to capital markets investors
• Enables more efficient balance sheet management
• Can reduce the cost of funding compared to issuing corporate bonds

For investors:

• Provides access to asset classes that would otherwise be inaccessible (consumer loans, trade receivables, infrastructure revenues)
• Offers predictable, structured cash flows with defined risk parameters
• Enables diversification across large pools of assets
• Can offer attractive risk-adjusted returns compared to equivalent-rated corporate bonds

For the broader economy:

• Facilitates credit creation — banks can lend more because they can remove loans from their balance sheets
• Channels institutional capital into real-economy activities (mortgages, SME lending, infrastructure)
• Improves liquidity in credit markets

How Does Securitisation Work? The Key Components

1. The Originator

The originator is the entity that holds the underlying assets — a bank with a mortgage portfolio, a company with trade receivables, or an asset manager with a loan book. The originator initiates the securitisation by transferring assets to a special purpose vehicle.

2. The Special Purpose Vehicle (SPV)

The SPV — also called a Special Purpose Entity (SPE) — is a legally separate entity created specifically to hold the securitised assets. The SPV is bankruptcy-remote: it is legally isolated from the originator, meaning that if the originator runs into financial difficulty, the SPV’s assets are protected.  The SPV issues the securities that are sold to investors.

3. The Securities

The SPV issues notes or certificates to investors, structured in “tranches” with different risk and return profiles:

• Senior tranches: The safest class, paid first, usually rated investment grade
• Mezzanine tranches: Middle tier, higher yield, higher risk
• Junior / equity tranches: The highest risk (first to absorb losses), but with the highest potential return

This tranching structure allows different types of investors — from pension funds seeking safety to credit funds seeking yield — to participate in the same underlying asset pool.

4. The Servicer

The servicer manages the underlying assets on behalf of the SPV — collecting loan repayments, managing arrears, and reporting to investors. Often the originator acts as its own servicer.

5. The Trustee and Other Parties

Independent trustees, rating agencies, auditors, and legal advisors all play roles in the securitisation process, ensuring transparency, compliance, and investor protection.

Types of Securitisation

Securitisation is used across a wide range of asset classes:

Mortgage-Backed Securities (MBS): Backed by pools of residential or commercial mortgages. The most well-known form of securitisation, and the backbone of the global fixed income market.

Asset-Backed Securities (ABS): Backed by consumer loans, auto loans, credit card receivables, or student loans. A major component of the fixed income universe.

Collateralised Loan Obligations (CLOs): Backed by portfolios of corporate loans, typically leveraged loans. CLOs are a major funding mechanism for the private credit market.

Trade Receivables Securitisation: Companies securitise their accounts receivable to convert short-term invoices into immediate liquidity.

Revenue-Based Securitisation: Cash flows from infrastructure assets, royalties, or subscription revenues can be securitised to provide upfront capital.

Bespoke / Private Securitisation: Single-asset or small-pool securitisations created for specific investment strategies — increasingly enabled by platforms like Otala Markets.

Securitisation and Structured Products: The Connection

Securitisation is the legal and financial process by which assets are transferred to an SPV and securities are issued against them.

Structured products are investment instruments that engineer a specific payoff profile using derivatives and other financial components.

In practice, many structured products use securitisation as their legal wrapper. An AMC, for example, is typically issued as a certificate by an SPV — the securitisation framework provides the legal structure, while the AMC’s investment strategy provides the performance engine.  Platforms like Otala Markets bridge these two worlds: providing the securitisation infrastructure (the SPV, the legal framework, the regulatory compliance) that allows structured products and AMCs to be issued, managed, and distributed efficiently.

The Evolution of Securitisation: From Banks to Technology Platforms

Securitisation has historically been dominated by large banks and institutional arrangers. The complexity and cost of establishing an SPV, navigating regulatory requirements, and distributing securities meant that only large-scale transactions were economically viable.

That is changing.

Technology platforms are now making it possible to issue securitised instruments — including certificates, notes, and AMCs — at a fraction of the historical cost and timescale. API-driven issuance engines can automate many of the operational and administrative processes that previously required teams of lawyers and bankers.

Otala Markets, through the ShellX platform, offers exactly this: institutional-grade securitisation infrastructure, accessible through a modern API, with transparent economics for originators and distributors. What once took months and seven-figure minimums can now be accomplished in days.

Regulatory Framework

Securitisation in Europe is governed by the EU Securitisation Regulation (Regulation (EU) 2017/2402), which came into effect in January 2019. Key provisions include:

• Due diligence requirements for institutional investors
• Risk retention: Originators must retain at least 5% of the economic interest in the securitised assets (“skin in the game”)
• Transparency and reporting: Issuers must provide detailed disclosure to investors and regulators
• Simple, Transparent and Standardised (STS) label: A quality designation for securitisations that meet specific criteria, providing regulatory capital benefits for certain investors

Understanding the regulatory framework is important for any issuer or investor participating in the European securitisation market.

Key Risks in Securitisation

As with any investment, securitisation carries risks that must be understood:

• Credit risk: If the underlying borrowers default, the cash flows to investors are reduced. The tranching structure mitigates this — senior investors are protected by subordination — but no instrument is risk-free.
• Prepayment risk: Borrowers may repay loans early (for example, if interest rates fall), altering the expected cash flows to investors.
• Liquidity risk: Some securitisation tranches — particularly mezzanine and junior notes — can be illiquid and difficult to sell before maturity.
• Structural complexity: Securitisations can involve complex legal and financial structures. Investors should ensure they fully understand the terms of any instrument before investing.
• Counterparty risk: The SPV’s bankruptcy-remote structure mitigates originator risk, but counterparty risks from servicers, swap providers, and other parties remain.

Why Securitisation Matters for Wealth Managers and Their Clients

For wealth managers, securitisation is relevant in two distinct ways:

As an investment: ABS, MBS, and CLO instruments offer portfolio diversification, attractive risk-adjusted yields, and low correlation to traditional equity and bond markets. As interest in alternative fixed income grows, securitisation is increasingly part of sophisticated wealth management portfolios.

As an issuance tool: Wealth managers and independent asset managers who want to issue investment products — structured notes, AMCs, or bespoke certificates — rely on securitisation infrastructure to do so. Platforms like Otala Markets provide this infrastructure in an accessible, technology-driven format.

In both cases, understanding securitisation is becoming an increasingly valuable competency for professionals in the wealth management and investment space.

Conclusion

Securitisation is far more than a technical financial mechanism — it is a fundamental building block of the modern investment economy. It enables capital to flow from investors to real economic activity, allows complex risk to be structured and distributed efficiently, and underpins a vast range of investment products from mortgage bonds to AMCs.

As technology continues to lower the barriers to securitisation issuance, more participants — asset managers, advisors, fintechs, and their clients — will be able to access and benefit from these structures. Understanding the fundamentals of securitisation is the first step.
