Despite this increase, experts remain cautiously optimistic. Property research firm Cotality notes that while arrears have risen from record lows, they are still below the recent high of 1.86% recorded in the second quarter of 2020. This suggests that, although financial pressures are mounting, the majority of borrowers continue to manage their mortgage obligations effectively.

Several factors contribute to this resilience. Tighter lending standards, including the Australian Prudential Regulation Authority's (APRA) mortgage serviceability buffer, have ensured that borrowers are assessed for their ability to repay loans at interest rates 3% higher than the current rate. This precautionary measure has likely mitigated the risk of default, even as actual rates have risen.

Additionally, the strong labour market plays a crucial role. With unemployment rates remaining low, many Australians have maintained steady incomes, enabling them to meet increased repayment obligations. The household saving ratio, which held above 10% between mid-2020 and early 2022, also indicates that many borrowers have financial buffers to draw upon during challenging times.

Looking ahead, the Reserve Bank of Australia's recent interest rate cuts are expected to provide relief to borrowers. These reductions may help stabilize or even reduce arrears rates, as lower repayments ease the financial burden on households. However, borrowers are advised to remain vigilant, monitor their financial health, and seek professional advice if they anticipate difficulties in meeting their mortgage commitments.
