From S&P:
The number of delinquent housing loans underlying Australian prime residential mortgage-backed securities (RMBS) fell to 1.23% in February from 1.29% in January, according to a recent report by S&P Global Ratings. We normally expect arrears to increase month on month in February, reflecting the seasonal effects of Christmas spending and summer holidays. The month-on-month decline was unexpected, particularly at a time of rising interest rates.
The report, “RMBS Arrears Statistics: Australia,” shows mortgages 31-60 days in arrears recorded the greatest improvement in February after recording the largest increase in January. The major banks recorded the largest decline in mortgages 31-60 days in arrears. Outstanding loan balances originated by major banks make up more than half of total RMBS loan outstandings, and their arrears performance has a significant influence on the Standard & Poor‘s Performance Index (SPIN) for Australian prime mortgages.
