Securitisation is the process of pooling loans, leases or receivables into a separate vehicle that issues securities to investors, so the originator raises funding and transfers risk.

Also known as: securitization

Key points

  • Assets are sold to a bankruptcy-remote special purpose vehicle (SPV), so investors are paid from the pool, not the originator's balance sheet.
  • Cash flows are split into senior, mezzanine and equity tranches with different credit risk and yield, paid in a set order (the waterfall).
  • Credit enhancement such as subordination, overcollateralisation, reserve accounts and excess spread lifts the credit quality of senior notes.
  • Collateral ranges from home loans to equipment leases and trade receivables; the notes issued are asset-backed securities, or residential mortgage-backed securities for home loans.
  • APRA's Prudential Standard APS 120 binds banks and other authorised deposit-taking institutions, with APG 120 as guidance; non-bank originators are not APRA-regulated.

Frequently asked questions

How does securitisation work?

A lender pools similar loans or receivables and sells them to a special purpose vehicle. The SPV issues notes in tranches to investors and uses the repayments from the pool to pay them in a set order, senior notes first. The lender usually keeps servicing the loans and earns a fee for it.

What is the difference between securitisation and covered bonds?

In a securitisation the assets are sold to an SPV and investors rely on the pool alone. With covered bonds the assets stay on the issuer's balance sheet and investors have dual recourse: to the issuer and to the cover pool of assets.

What is an SPV in securitisation?

A special purpose vehicle is a separate legal entity set up to hold the pool of assets and issue the securities. It is designed to be bankruptcy-remote, meaning the assets sit outside the originator's estate, so investors keep being paid from the pool even if the originator becomes insolvent.

What is a warehouse facility?

A warehouse facility is short-term funding, often from a bank, that lets an originator accumulate loans until the pool is big enough and seasoned enough for a term securitisation. Warehouse lenders set covenants, concentration limits and reporting requirements while the pool is being built.

Is securitisation risky?

The risks depend on the tranche. Senior notes carry structural protection from subordination, reserve accounts and overcollateralisation; equity and unrated mezzanine tranches absorb losses first. Borrower defaults, prepayment speed, servicing quality and legal isolation of the assets all affect returns, so investors look closely at loan-level data, the waterfall and legal opinions.
