Macquarie outlines the impact of interest rate cuts on major Australian banks
Banks with high exposure to non-interest-bearing deposits may face margin pressure
US tariffs have indirect implications for the Australian economy, possibly supporting RBA easing
The ASX banking sector has previously gained from elevated interest rates, particularly through income generated from products such as transaction accounts that do not pay interest. With the Reserve Bank of Australia signaling the prospect of rate cuts, market participants have been assessing how these changes may affect the profit margins of Australia’s largest financial institutions. Recent commentary from investment firm Macquarie offers insight into which banks could face earnings pressure in a lower interest rate environment.
Impact of lower rates on bank profitability
High interest rates have enabled banks to increase earnings by widening their net interest margins, especially from deposits that do not accrue interest. As rates decline, the margin between funding costs and lending revenue narrows. This dynamic may lead to pressure on profitability, particularly for banks that rely heavily on low-cost deposit funding. In this context, the focus has turned to identifying which of the largest ASX-listed banks could be more exposed to a margin squeeze as the cash rate declines.
Macquarie highlights two banks with margin sensitivity
According to Macquarie, two of the country's largest banking institutions may be the most impacted by rate cuts due to their funding composition and deposit exposure. These banks maintain a larger share of their funding base in non-interest-bearing deposits, which has been a source of margin benefit in a high-rate environment. As rates decline, the income advantage derived from these deposits diminishes, affecting earnings. While all major banks are influenced by interest rate changes, those with a greater proportion of transactional deposit funding may see more noticeable shifts in their margins.
US tariffs and their broader economic impact
In addition to interest rate developments, Macquarie has commented on recent trade actions by the United States. The implementation of new tariffs on goods from several countries is seen to have a direct economic impact on Australia that is relatively minimal. However, the broader implications may be more significant, depending on how trading partners are affected. These trade disruptions could influence global commodity demand, business spending, and consumer sentiment. Any resulting economic softness may contribute to a monetary policy response by the RBA, which would include the easing of interest rates.
Implications for rate settings and banking sector dynamics
Export re-routing as a result of trade barriers may contribute to price changes in the goods sector, potentially providing room for monetary authorities to adjust policy. As inflation moderates, there is increased flexibility for rate changes. For banks, a lower rate environment can alter revenue profiles and funding strategies. Those institutions more reliant on deposits for funding may need to reassess their asset and liability structures to navigate a changing rate landscape.
Performance trends since policy announcements
Since the announcement of new US tariffs, Australian bank shares have moved broadly in line with the overall share market. This suggests that the immediate reaction to trade policy changes has been neutral within the sector. However, the longer-term effects of interest rate adjustments on bank earnings remain under observation. The intersection of domestic monetary policy and global trade dynamics continues to shape the outlook for financial institutions on the ASX.
