Public mortgage insurance, covered bonds, better credit reporting, more work on electronic conveyancing, less regulation and easier entry to the industry all feature on the wish-list included by the Australia Bankers Association in its submission to the Senate banking inquiry.Prominent in its list, to some readers, may be the ABA declaring its hand as a supporter of greater government involvement in the secondary mortgage market,  specifically, via a form of public insurance.Calls for government aid for the mortgage market date back to the start of the credit crunch, in 2007, and have continued even as the government, through the Australian Office of Financial Management, began to invest in mortgage securities.The ABA view may not matter much as Canberra's policy wheels engage with the banking industry, but it's interesting that this is also the ABA view, which reflects the views of its smaller members.The ABA, in its submission, said it believed "that by establishing a government corporation or market-based [special purpose vehicle] which provides mortgage default insurance to mortgage lenders, this reform could facilitate the securitisation of a part of the residential mortgage pool."
