Securitisation – Regulation, Reality and Why Securitisation Still Matters

If securitisation were nothing more than a clever financial trick, it wouldn’t have survived.
It would have been regulated out of existence after 2008 – boxed up alongside other ideas the world decided it could live without. Instead, securitisation is still here. Changed. Constrained. Quieter. But very much alive.

That persistence tells us something important.

Securitisation didn’t fail because it existed.
It failed because it was misunderstood, misused, and misaligned.

This piece explains how regulation reshaped securitisation – and why, despite that scrutiny, it remains a central part of modern finance.

What 2008 Actually Changed

The financial crisis didn’t reveal that securitisation was inherently broken.
It revealed something more uncomfortable: structures designed to allocate risk had been used to disguise it.

The problems were not caused by securitisation itself, but by:

• weak underwriting,
• poor asset quality,
• excessive leverage,
• opaque re-securitisations,
• and a dangerous separation between those who originated risk and those who ultimately bore it.

In short, incentives had drifted.

Post-crisis regulation was not about banning securitisation. It was about forcing those incentives back into alignment.

Risk Retention: Aligned Incentives

One of the most consequential regulatory responses was risk retention.

Under modern frameworks, originators and sponsors are required to retain a material economic interest in the securitisation – typically around 5% – and to do so in prescribed ways.

The logic is straightforward. People behave differently when they can’t walk away.

Risk retention ensures that:

• originators suffer alongside investors if assets deteriorate,
• underwriting standards matter again,
• and structures are not built purely to offload risk as quickly as possible.

It doesn’t prevent losses. It makes sure they are shared.

Transparency as a Feature, Not a Burden

Modern securitisations are far more transparent than their pre-crisis predecessors.

Detailed reporting, standardised disclosures, and ongoing performance data are no longer optional. They are the price of entry.

Investors now expect:

• loan-level or pool-level data,
• regular performance reporting,
• clear explanations of triggers and remedies,
• and consistency between marketing and documents.

This isn’t regulatory overreach. It is market discipline catching up.

Securitisation works best when everyone can see what’s happening – even when they don’t like what they see.

Financial Promotion Rules: Fewer Spectators, Better Players

One of the quieter but more important changes has been the tightening of financial promotion rules.

Securitisation is no longer dressed up for audiences it was never meant for. Complex structures are restricted to professional investors who:

• can analyse the risks,
• understand how losses behave,
• and aren’t relying on sales narratives to do the thinking for them.

This matters.

Securitisation is powerful precisely because it’s precise. Selling it badly – or to the wrong audience – undermines that precision.

Modern regulation recognises this and draws firmer lines around who these products are for.

Consumer Duty and the Limits of Structure

The rise of Consumer Duty reinforces another boundary.

While most securitisations sit firmly in wholesale markets, the principles behind Consumer Duty send a broader message: good outcomes matter more than clever structures.

That has implications for:

• asset selection,
• distribution chains,
• and how securitised products interact with retail markets, even indirectly.

Securitisation can’t rescue poor products upstream. No amount of structuring can compensate for assets that should never have been originated.

Regulation now makes that explicit.

Non-Bank Finance and the Quiet Comeback

After the crisis, banks became more constrained. At the same time, non-bank financial institutions quietly became more important.

Pension funds, insurers, asset managers, and credit funds need access to predictable cashflows. Securitisation provides it.

At the same time banks need to:

• manage capital,
• free up balance sheets,
• and recycle risk efficiently.

Securitisation sits between those needs.

It isn’t loud. It isn’t fashionable. But it works.

Mortgage Markets as a Reality Check

Residential mortgage-backed securities (RMBS) offer a clear example of this evolution.

Pre-crisis RMBS often relied on optimistic assumptions and weak underwriting. Today RMBS looks very different:

• simpler structures,
• stronger documentation,
• conservative credit enhancement,
• and clearer alignment of interests.

The product survived because the function never disappeared. People still need mortgages. Banks still need funding. Investors still want long-dated, stable cashflows.

Regulation changed the how, not the why.

What Securitisation Is Now (and Is Not)

Modern securitisation is:

• constrained,
• transparent,
• conservative,
• and deliberate.

It is not:

• a dumping ground for bad risk,
• a substitute for credit judgement,
• or a way to avoid responsibility.

If anything, securitisation now demands more discipline than traditional lending. Structures are unforgiving. Data is relentless. Weaknesses surface quickly.

That isn’t fragility. It’s honesty.

Why Securitisation Endures

Securitisation endures because it solves real problems.

It:

• connects long-term investors with real economy cashflows,
• allows risk to be priced rather than hoarded,
• and enables credit to flow without concentrating exposure in a single institution.

No alternative does all of that as efficiently.

Regulation didn’t kill securitisation because it couldn’t. The modern financial system still needs a way to move risk, capital and cashflows intelligently.

Securitisation – done properly – remains one of the few tools capable of that.

The Last Word

Securitisation isn’t a loophole.
It isn’t a scandal waiting to happen.
And it isn’t a relic of a wilder financial age.

It is a system.

A system built on:

• contractual clarity,
• disciplined risk allocation,
• and a clear-eyed acceptance that losses happen – but should happen where they are expected.

If you understand securitisation, you understand something fundamental about modern finance: not how money is made, but how risk is managed.

And in a world that will never stop lending, borrowing, or occasionally getting things wrong, that understanding still matters.
