A large month for bond maturities is looming in October. Commonwealth and semi-government bonds account for over 80% of the $20bn of debt maturing in October. It’s not a seasonal thing either; the $4bn due in October 2016 is more in line with the $5-10bn which is due for repayment in a typical month. Regardless of the composition of the maturities, there’s a surge of funds to be transferred from government accounts to bond holders shortly and those funds will likely be looking for a home.
