Australia’s mortgage burden is now above 1989 levels – when interest rates were 17%

Australia’s Mortgage Burden Surpasses 1989 Levels Amid Rising Costs

Australia s mortgage burden is now above - A new study reveals that the current mortgage burden in Australia is more significant than it was during the late 1980s, when interest rates peaked at 17%. Urban economist Terry Rawnsley from KPMG highlighted that this analysis challenges common perceptions, demonstrating that today’s homeowners face greater financial strain than their predecessors. “The data underscores a clear trend,” Rawnsley noted, emphasizing that home loan payments have evolved from a source of stability to a growing cause of worry for many families.

Historical Context and Rate Peaks

According to the Reserve Bank of Australia (RBA), interest rates reached 17% in mid-1989, with the cash rate peaking at 17.5% in 1990. These high rates persisted for nearly a year, creating a period of intense borrowing costs. The KPMG research, however, shows that even with rates dropping to roughly half their 1989 levels, the proportion of household income spent on mortgages has risen sharply. In 1990, interest payments accounted for 5.7% of total household income, with 3.4% dedicated to housing loans and 2.3% to consumer debt. By early 2026, the average home loan rate had climbed to 8.3%, nearly doubling the 1990 figure, despite the overall rate decline.

The Paradox of Lower Rates and Higher Debt

Rawnsley’s analysis points to a paradox: although lending rates are now only half what they were in the 1980s, households are allocating a higher percentage of their income to mortgage servicing. Currently, 5% of household earnings go toward mortgages, with an additional 5.4% covering consumer debt obligations. This trend is expected to intensify as the effects of recent interest rate hikes take hold, pushing the total debt burden toward 6% of income. “The data indicates that borrowing conditions have worsened in recent years compared to the late 1980s,” Rawnsley explained, refuting the notion that past decades were the most challenging for homebuyers.

“Even with rates halved, the financial pressure on families has increased significantly. This aggregate number masks a wide range of experiences, from first-time buyers drowning in debt to those who’ve owned homes for decades with little concern.”

Rawnsley acknowledged that the 1980s and early 1990s were often cited as periods of extreme housing stress, but his findings suggest otherwise. While homeowners then grappled with a double-digit unemployment rate, today’s challenges stem from a different set of factors—rising property prices, stagnant wage growth, and a decline in home ownership rates. “The past few years have seen a greater proportion of households burdened by mortgages, even as ownership rates have fallen steadily,” he said.

Recent Market Volatility and Policy Impacts

Despite the current mortgage burden, recent months have seen a temporary dip in Sydney and Melbourne home prices, driven by climbing interest rates, the cost of living crisis linked to the Middle East conflict, and recent tax reforms. However, Tim Reardon, chief economist at the Housing Industry Association (HIA), argued that this decline is unlikely to last. “Short-term price drops are common, but they often precede prolonged periods of rapid growth,” he stated, citing HIA data that shows housing affordability has reached its lowest point since 1994.

“Even a 5-10% decline in home prices only brings prices back to levels from 12 to 18 months ago. The long-term trend remains upward, and any relief is temporary.”

Reardon agreed that buying a home today is more difficult than it was in the late 1980s, attributing this to policy decisions that have reduced housing supply. He criticized Labor’s reforms to capital gains tax (CGT) and negative gearing, arguing they exacerbate affordability issues by limiting new housing developments. “Maintaining rental vacancies above 3% is key to stabilizing prices,” Reardon said, “but the goal should be long-term price stability, perhaps spanning a decade or more.”

Broader Implications for Household Stability

The KPMG report also underscores the disparity in how different groups are affected by mortgage stress. While some families are struggling to meet payments, others may have greater flexibility due to longer-term financial planning. Rawnsley’s data highlights that the aggregate figures reflect a mix of outcomes, including first-time buyers, mid-term mortgage holders, and those who purchased homes years ago. “The overall number tells a story, but it’s the individual experiences that matter most,” he emphasized.

Analysts warn that the combination of high debt levels and fluctuating property markets could lead to long-term economic strain. With home values continuing to rise and borrowing rates fluctuating, households face a precarious balance between securing housing and managing other financial commitments. The RBA’s historical data, when paired with modern trends, paints a picture of a housing market that has grown more complex over time. While the 1980s saw peak rates, the current era is marked by a different kind of challenge—one where affordability and debt sustainability are central concerns.

A Call for Policy Reforms

Rawnsley and Reardon both agree that addressing the mortgage burden requires targeted policy interventions. Rawnsley stressed the need for measures that reduce the financial strain on first-time buyers, while Reardon focused on supply-side solutions. “The goal shouldn’t be just to stabilize prices, but to ensure they remain stable for extended periods,” Reardon said. “This would provide greater certainty for families and support long-term economic growth.”

As the housing market continues to evolve, the debate over past versus present challenges will likely persist. Yet, the data suggests that today’s homeowners are facing a more severe financial landscape, with the burden of mortgages surpassing historical levels. Whether this trend continues or reverses depends on a combination of policy decisions, economic conditions, and the resilience of households in the face of rising costs. For now, the statistics remain a stark reminder that the path to homeownership has become increasingly difficult, even as the economy adapts to new realities.
