Bond Market Rises as Governments Face Higher Interest Rates

Government debt is causing concern in the bond market as interest rates rise. In Australia, the Reserve Bank of Australia (RBA) has lifted the cash rate to fight inflation, affecting mortgage holders and businesses alike.

The Australian government's 10-year bonds have hit a 15-year high after a long period of low interest rates since the global financial crisis in 2008. Similarly, in the US, 10-year interest rates sit around 4.7%, while in the UK, 10-year bond rates have reached their highest level since the global financial crisis.

The rise in government debt is driving up market interest rates. The main driver of this increase is the growing size of government debts worldwide. For instance, the US national debt has exceeded $40 trillion, more than 20 times Australia's entire economy, while Australia's federal government debt recently passed $1 trillion.

Central banks can influence short-term interest rates but have limited control over longer-term debt. The RBA's inflation target of 2-3% helps keep market interest rates low by maintaining a lid on consumer inflation expectations.
