From Deutsche:
Repricing of interest-only mortgages
In recent weeks the majors have announced repricing initiatives targeted at interest-only (IO) mortgages. While they raised IO rates by 30-35bps, owneroccupier principal & interest (P&I) rates were reduced by 3-8bps. These moves were responses to regulatory restrictions aimed at dampening housing risks rather than responses to the bank levy. We expect margin benefits to be partly offset by a substantial proportion of owner occupiers on IO switching to P&I (we assume 75%) and the changes accentuating a slowing in housing credit growth. As such our cash NPAT forecasts have increased by just ~1% on avg in FY19. Our top picks remain WBC and NAB.
