Sarah Hunter, Assistant Governor for Economic Forecasting at the Reserve Bank of Australia (RBA), has issued a stark warning regarding the global economic outlook, anticipating a future marked by more frequent and intense supply shocks. Speaking in Canberra, Hunter underscored that events akin to the energy crisis spurred by the Iran war are likely to recur, intensifying trade-offs for central banks and reinforcing the critical mandate for achieving low and stable inflation.
Hunter elaborated that these more frequent supply shocks are poised to intensify the inherent trade-offs faced by both central banks and the broader economy. She emphasized the paramount importance of thoroughly understanding, preparing for, and effectively responding to such episodes. The goal, she stated, is to minimize the risk of persistent inflation while simultaneously supporting sustainable economic activity. Despite these efforts, Hunter conceded that some economic costs are ultimately unavoidable. ‘Ultimately, though, some economic costs are unavoidable,’ Hunter said Wednesday in the text of a speech. ‘All policymakers can do is strike a balance in the face of a worsening trade-off.’
RBA’s Proactive Stance on Inflation
The RBA’s recent monetary policy actions reflect a hawkish stance in anticipation of these challenges. The central bank raised interest rates at its first three meetings of the year before opting for a pause last month, holding the cash rate at 4.35%. This aggressive tightening cycle was initiated to preemptively counter resurgent inflation, even prior to the Middle East conflict’s impact on fuel prices. The conflict significantly elevated the risk of second-round effects across the economy, given energy’s pervasive importance.
Hunter specifically referenced the Phillips Curve, a key economic model illustrating the inverse relationship between inflation and unemployment. She noted that ‘The current oil price shock has shifted the curve out somewhat, implying higher underlying inflation for any level of unemployment.’ This outward shift suggests that policymakers now face a more challenging environment where achieving a desired level of employment may come with a higher inflationary cost than previously anticipated. Furthermore, Hunter warned that ‘Inflation may respond more strongly if shocks occur while underlying inflation is already elevated,’ which significantly raises the risk of inflation expectations becoming untethered from the central bank’s target. The potential consequences extend to economic activity, as ‘The effects on activity could be larger if households and businesses become more cautious or if their financial buffers have been eroded.’
Lessons from Past Shocks and Global Contrasts
The RBA’s current hawkish approach stands in notable contrast to the ultra-easy monetary policies pursued by many global central banks during previous major supply shocks, such as the Covid pandemic and Russia’s invasion of Ukraine. During those periods, central banks, led by the Federal Reserve, initially characterized rising price pressures as ‘transitory.’ This assessment, however, proved to be a misjudgment as inflation broadened and accelerated, leading to a delayed but ultimately aggressive tightening cycle globally.
Australia’s economic structure also contributes to its vulnerability. The RBA last year lowered Australia’s potential growth rate to approximately 2%, a revision that reflects the economy’s subdued productivity performance in recent years. This lower potential growth rate means the economy is more susceptible to inflationary pressures if economic activity gains too much momentum and begins to encounter capacity limits. Such conditions make the economy more prone to bursts of inflation, even from moderate demand-side pressures, let alone significant supply-side disruptions.
Anticipating Future Disruptions
Hunter identified several distinct types of shocks that are currently in train and are expected to shape the future economic landscape:
- Economic spillovers stemming from rising geopolitical tensions, which can disrupt trade routes, investment flows, and resource availability.
- Increased trade fragmentation, indicating a move away from globalized supply chains towards more regionalized or protectionist trade policies, potentially increasing costs and reducing efficiency.
- The increasing prevalence of extreme climate events, which can severely impact agricultural output, infrastructure, and energy supply, leading to direct inflationary pressures and economic disruption.
Despite the complexity and difficulty these shocks present, Hunter unequivocally stated that they do not diminish the fundamental importance of maintaining low and stable inflation. ‘Ultimately, while supply shocks create difficult trade-offs, they do not lessen the importance of maintaining low and stable inflation,’ she affirmed. The RBA remains steadfast in its commitment to its dual mandate. ‘The board will continue to act as needed to ensure inflation returns to target and the labor market to sustainable full employment,’ Hunter concluded, reiterating the RBA’s aim for the midpoint of its 2-3% inflation target.
