Ready. Set. Go.
With the release of ARS 117.0 Repricing Analysis, the Australian Prudential Regulation Authority (APRA) has introduced one of the most significant and challenging reporting changes to affect banks in recent years. Effective from periods ending on or after 1 October 2025, ARS 117.0 imposes new levels of detail, governance, and analytics on banks’ interest rate risk reporting under the revised APS 117 standard. While the reforms aim to strengthen risk oversight, they also bring real challenges — especially for smaller and mid-sized Authorised Deposit-taking Institutions (ADIs).
Fortunately, CoreBIS understands the strain these regulatory shifts place on finance, risk, and data teams. That’s why we’ve made it our mission to ensure ARS 117.0 compliance is not only possible, but practical — with a powerful, automated, and transparent solution built specifically for the APRA reporting landscape.
What is ARS 117.0 — and Why Is It So Challenging?
ARS 117.0 is APRA’s new reporting standard that requires ADIs to submit detailed data about the repricing profile of their banking book exposures. It forms part of the broader Interest Rate Risk in the Banking Book (IRRBB) framework under APS 117 and is designed to give APRA better visibility into an institution’s balance sheet and its sensitivity to interest rate shocks.
Key challenges for banks:
- Increased data granularity: Institutions must classify and report exposures across precise repricing time buckets and categories — often requiring new definitions and data not historically captured in existing systems, such as interest cash flows.
- Complex validation rules: ARS 117.0 comes with numerous validation rules to ensure data accuracy and consistency across submissions.
- Deposit Replicating Portfolio: ADIs that conduct behavioural analysis to determine core vs non-core deposits must calculate the expected repricing for all core deposit balances using different methodologies, including the APRA-prescribed profile.
- Contractual and Expected Repricing: The new ARS 117.0 can require a combination of Contractual Repricing (Table 1) and Expected Repricing (Table 2), depending on an ADI’s class and internal modelling.
- Interest rate sensitivity calculation: ARS 117.0 Table 3 requires a brand new complex calculation of interest rate sensitivities across specified tenor buckets for six interest rate shock scenarios, aggregated across reported currencies.
- New submission channels: All reports must be filed via APRA Connect, requiring an end-to-end rethink of legacy reporting workflows and processes.
For many ADIs, this presents a significant operational challenge — one that impacts not just regulatory reporting teams, but also risk management, data governance, and IT.
