One theory prominent in banking circles in the lead up to Australia's inconclusive election was that a returned Liberal National coalition may find itself obliged to yield to calls for a banking royal commission in order to appease the Greens and a hostile Senate at some point.Strategists will now have to consider the implications for a minority LNP government - if that is the final outcome - and the positions of the cross bench MPs in the House of Representatives on any inquiry into the sector.Of the five "other" MPs elected or returned to parliament at the weekend, at least three are on the record as supporting a royal commission; Bob Katter, Adam Bandt and Rebekha Sharkie from the Nick Xenophon Team.NXT leader Nick Xenophon has said an LNP minority is the most likely outcome, but, like the Greens, has long called for a royal commission in banking.Mike Hirst, managing director of Bendigo and Adelaide Bank told Fairfax Media "everyone should be pleased" that a royal commission won't proceed under a Coalition government.In the Financial Review columnist Adele Ferguson countered this view: "The chaos and uncertainty will make the banks nervous that a royal commission into the banks might just happen, no matter who forms government. The ALP, Greens and the Nick Xenophon party are all in favour of a royal commission. Some inside the Coalition have also signalled their support."
