Reserve Bank of Australia cash rate stays primary tool after policy review

RBA cash rate policy will remain the Reserve Bank of Australia’s central lever, but a new framework sets out how extra measures could be deployed in extreme conditions.

Assistant Governor Chris Kent said on Monday the central bank is seeking to be better positioned for the next period of acute stress after reassessing unconventional monetary options. Speaking in Sydney, Kent said the cash rate target is still the institution’s preferred instrument, while other tools can offer added support but also bring greater complexity and risk.

New framework maps out “additional” tools at low rates

The comments accompanied the release of the Monetary Policy Board’s “Framework for Additional Monetary Policy Tools at Low Interest Rates.” The document outlines how the central bank would think about options beyond the cash rate when conventional cuts provide limited traction.

Kent, who oversees financial markets at the RBA, stressed that non-standard measures are intended for “extraordinary times.” He indicated the framework is aimed at preparedness rather than signalling imminent changes in policy implementation.

A key point highlighted in the speech was that the board may respond differently when the cash rate is already low. Under those conditions, Kent said policymakers may be less willing to accept inflation persistently undershooting the RBA’s 2% to 3% target band.

He said that in such an environment the board could choose to act sooner against disinflationary shocks, including cutting the cash rate target earlier and more forcefully than it otherwise might. The message reflects an effort to reduce the odds that inflation and expectations drift too low when policy space is constrained.

Covid-era measures inform the lessons in the review

The RBA’s experience during the pandemic sits behind the new framework. In response to the Covid shock, the central bank lowered the cash rate to 0.1% and introduced a yield target, alongside a government bond purchase program.

The RBA also used forward guidance under then-Governor Philip Lowe, including time-based messaging about how long rates might stay low. That approach later proved problematic when inflation accelerated after Covid-era disruptions eased and demand recovered, forcing the central bank to tighten policy more rapidly than many had anticipated.

Kent’s speech positioned the new framework as a way to weigh trade-offs more explicitly if similar conditions re-emerge. While unconventional tools can amplify support when rates are near their effective floor, they can also affect market functioning, create distributional effects, and complicate communication with households and investors.

Implications for future decision-making and communication

The emphasis on the RBA cash rate as the primary instrument is likely to reinforce expectations that the board will prefer conventional adjustments where possible. At the same time, formalising guidance on “additional” tools may reduce uncertainty about how policymakers would react if a deep downturn pushed rates close to zero again.

The framework’s focus on avoiding prolonged inflation undershoots at low rates also points to a more pre-emptive posture in a severe disinflation scenario. That could matter for financial markets because it suggests the hurdle to cutting rates in a downturn may be lower when policy capacity is limited.

Next steps will hinge on how the Monetary Policy Board communicates its reaction function as economic conditions evolve. Investors will watch future speeches and statements for how the board balances the risks of doing too little against the operational and financial stability costs that can come with non-standard interventions.
