APRA announced yesterday that has decided to publish industry level data showing the aggregated commercial property exposure limits for all Australian ADIs.  "Releasing data on exposure limits allows for more robust analysis of ADIs' commercial property exposures … [and] are the amount an ADI has committed to make available to a borrower," the regulator explained.  In other words, this represents the potential actual exposure should the facilities be fully drawn, although in practice, not all lines of credit are fully drawn throughout the life of a facility, and contractual terms may, for risk management purposes, prevent a borrower from accessing all committed funds at once.  In APRA's first bulletin, which aggregated statistics up to 30 September 2016, the sector highlights were: ADIs' commercial property exposure limits were A$309 billion, 19 per cent higher than actual exposures of $260 billion; the categories with the highest aggregate exposure limits were office property ($87 billion) and retail property ($69 billion), together comprising over half of the industry's total exposure limits; and exposure limits to land development, subdivision and office experienced the greatest growth for the year to 30 September 2016 (12 per cent and ten per cent, respectively). APRA stated that its sample of data, which comprises banks with the largest commercial property exposures, accounts for "approximately 99 per cent of total ADI commercial property exposures," with the remaining one per cent of ADI exposures estimated using previous quarters' data.  "Past downturns in commercial property markets have had significant negative impacts on a number of Australian ADIs and overseas banks, highlighting the need to subject the sector to ongoing prudential supervisory attention," APRA said.
