ME Bank aims to develop a wholesale debt curve, following its debut sale of A$325 million in senior debt funding on Friday.Nick Vamvakas, chief risk officer of the bank, said it was the first time ME Bank has come to the market with a publicly issued floating-rate note outside of the government guarantee scheme.Institutions have invested in the term debt of ME Bank before, but only in term deposits and shorter-term securities.Westpac Institutional Bank, which helped sell the bonds, said they were priced at a spread of 125 basis points over the three-month swap rate.Vamvakas said this price was little different to the all-in cost of packaging debt into mortgage-backed bonds, the bank's traditional source of long-term funding.He said the recent ratings upgrade from Moody's and Standard & Poor's made the issue repurchase eligible with the Reserve Bank of Australia.Vamvakas said the bank planned to develop a yield curve (that is, bonds of different tenors) for its senior debt.
