National Australia Bank (NAB) reiterated that its capital position is comfortable at its May 8 half-year results announcement, despite a clutch of recent regulatory moves which add to the capital burden of the bank and its peers. NAB also updated its internal common equity tier-one (CET1) target, setting its goal at 0.75-1.25 per cent above the new regulatory minimum for domestic systemically important (D-SIB) banks.
