NAB has the largest market share in commercial lending and the second-highest transaction banking market share, which makes it a strong candidate for having the riskiest loan book with regard to Australian commercial lending.
However, an analysis by Wilson HTM of listed companies that have lost more than 20 per cent and more than 50 per cent of their market capitalisation in the past year, NAB may have the lowest exposure of all the banks to poorly performing companies when ranked by debt outstanding.
