Westpac New Zealand has posted a 41 per cent rise in annual cash earnings after a big drop in impairment charges as rise in income as net interest margins rose.
Westpac's cash earnings for the year to September 30 rose to $454 million from $322 million the previous year. The bank's net operating income rose 8 per cent to $1.668 billion outstripping a 5 per cent rise in operating expenses to $784 million. Australian parent Westpac Banking Corporation posted just a 7 per cent rise in annual cash earnings to A$6.3 billion.
Impairment charges fell 32 per cent to $236 million.
Net interest margins, helped by customers switching to more lucrative floating, or variable, rate mortgages from fixed-term ones, rose 22 basis points across the year to 2.33 per cent and 9 basis points in the second half-year to 2.38 per cent.
Nearly 60 per cent of industry wide home loans by value are now on floating rates compared with 87 per cent on fixed-term rates just three years ago. Banks tend to do better out of floating, or variable, mortgages because the margin between the variable rate and short end of the yield curve, such as three month bank bills, is higher than the margin between swap rates and fixed rate mortgages.
