Macquarie Bank is winding up its UK cashflow lending business to insurance brokers, blaming market conditions in Britain.

A spokesman told insuranceNEWS.com.au the decision will have no impact on Australian operations and the UK insurance broking benchmark survey will continue as usual.

The £70 million ($86.87 million) loan book has been put into run-off.

Macquarie UK established the cashflow lending business in June 2007 to provide funds for brokers wanting to acquire or merge, buy out other shareholders or lock in key staff.

It says the state of the global economy and evolving regulatory environment in Britain were also factors in the closure decision.
