NAB is yet to lift its home loan lending rates - something that seems inevitable - but instead National Australia Bank CEO Andrew Thorburn is back on the public relations round, the only big bank CEO making much of a PR effort as the Hayne royal commission grinds on.Speaking in in Wagga Wagga last night, Thorburn rattled off a couple of initiatives that may lower the cost of borrowing for agribusiness customers.The bank will offer its agri customers "the financial benefit of being able to offset their Farm Management Deposit against their agricultural lending," Thorburn said.This offset will take the form of a discount to their lending interest rate, he said.The NAB CEO added that the bank would agitate to allow Farm Management Deposit "to be allowed as security for lending. Whilst this has some challenges, including legislative change, it would give farmers access to additional security as capital to lend against."Thorburn said that for "those agri customers affected by drought [who] may fall into arrears and be unable to make their loan repayments, we want to help … not make it more difficult. "So, we will now not charge a higher default interest rate if this does occur. This matter came up in a recent royal commission case, and we have decided that change needs to occur."? Branch closures in the bush may also be slowed down by NAB, with Thorburn allowing that "perhaps there is more we can do to sustain those services, in conjunction with the community, such as partnerships and alliances." Or perhaps we need to consider changes to how we leave towns, if there is no alternative.Finally, Thorburn announced a couple of helpers for his senior team on rural roadshows: John Anderson, a former deputy prime minister, and indigenous educator Chris Sarra.
