The complex credit markets have enjoyed a further boost this week, with investor interest providing the opportunity for banks to place parts of deals they have had to keep on their balance sheets since the credit crisis began in 2007.

The securitisation market was a crucial way for banks to transfer the credit risk of loans to investors, freeing up their balance sheets. Issuance boomed up until the financial crisis, which many have blamed on the widespread use of securitisations. These deals involve parcelling up portfolios of loans or assets and selling parts of the credit risk of those portfolios to investors.
