The database has been unveiled following the success of two other CACI databases – the mortgage market database and the current and savings account database.
Since March, CACI has been trialling the new database with financial companies HSBC, HBoS, Lloyds TSB, The Royal Bank of Scotland, Natwest and Nationwide.
CACI invites lenders to supply detailed data on their unsecured personal loans and in return they receive a complete picture of the UK loans market.
Members can accurately measure performance against the market and examine aspects such as pricing structure, branch performance, channel and risk.
The database displays detailed product data such as price, term, channel, volume and value of loans and provides an accurate and detailed measure of the unsecured personal loans market.
The information is updated on a monthly basis. A weekly snapshot of new business performance is also provided as part of the membership.
Kirstie Kimberley, product development consultant at CACI, said: "CACI is launching PLDB in a market where existing data sources are limited and confusing.
"In the current economic environment, better market understanding is vital and the database is a source of real, accurate information."
