Australia's national debt has hit $1 trillion but there's another figure that's more important

Australia's national debt has recently surpassed $1 trillion, a milestone that has drawn attention beyond the usual political discourse. However, a more pressing concern for the nation lies in its household debt. At an alarming 190 percent of household income, Australia ranks higher than many developed nations in this category. This situation is exacerbated by the fact that Australian households owe more to real estate than to any other creditor, making them particularly vulnerable to changes in interest rates.

Economist Saul Eslake, a former Bank of America Merrill Lynch chief economist, notes that while Australia's debt-to-GDP ratio of 32 percent is comparatively low, the nation's debt burden needs to be addressed. After borrowing heavily during the COVID-19 pandemic, Australia now faces the prospect of higher global interest rates as those loans come due. Despite its Triple-A credit rating, Australia has consistently paid a higher interest rate than other nations, a trend that is expected to continue.

The issue is not just limited to government debt but also extends to household debt. With such a high percentage of household income tied up in debt, Australians are in a precarious position should interest rates rise. Economic conditions in the United States are further complicated by the country's skyrocketing national debt, which has doubled in just ten years, reaching $20 trillion under President Donald Trump.

With annual interest payments on this debt amounting to nearly $1 trillion, it has surpassed both the US defense budget and the social security and Medicare budgets combined. The Congressional Budget Office predicts that the US debt-to-GDP ratio could reach 137 percent within the next eight years, leading to consistently higher interest rates for the American economy.

This has significant implications for Australia, as its interest rates are historically higher than those of the US.
