Bond Market Sell-Off Remains a Risk as Australian Yields Hit 2011 Levels

AMP warns bond market pressure could persist as global debt, inflation and higher interest-rate expectations continue to weigh on investors

The global bond market sell-off remains a concern for investors, with Australia’s 10-year bond yield rising to levels last seen in 2011. AMP chief economist Shane Oliver said the recent increase reflects several pressures building across global financial markets, and warned that bond yields could rise further if those drivers remain in place.

Global debt and inflation fuel bond market pressure

Oliver pointed to large government budget deficits in the US and other economies as one of the key reasons behind the rise in bond yields. Higher public borrowing increases the amount of debt governments need to finance, adding pressure to bond markets as investors demand greater compensation.

At the same time, inflation remains another concern. Higher oil prices could keep inflation elevated, potentially requiring central banks to maintain interest rates at higher levels for longer. That combination of persistent inflation and heavy government borrowing has contributed to renewed pressure across global bond markets.

Oliver also highlighted increased corporate borrowing linked to data centre investment as another factor affecting bond markets. Rising Japanese bond yields have also contributed to a reversal of the so-called carry trade, adding another source of volatility.

US Treasury yields remain important for Australia

Movements in US government bonds are particularly important for Australian investors because US bond yields provide a base for global borrowing costs. As US yields rise, the pressure can flow through to Australian government bonds.

For Australia, this has been compounded by stronger expectations around the RBA’s cash rate following elevated inflation data. Higher expected interest rates can put additional upward pressure on government bond yields.

Oliver was also critical of recent intervention by US Treasury Secretary Bessent, arguing that investors viewed it as lacking fundamental support because it was not accompanied by measures to address the country's large budget deficit.

Yields could climb towards 5.5%

Despite some easing in bond selling after comments from a US Federal Reserve governor suggested the US economy could potentially avoid another rate increase later this year, Oliver believes the broader bond market risks remain.

He said it is difficult to see the key drivers of higher yields disappearing in the near term and described the return of “bond vigilantes” as consistent with a world of higher inflation and elevated public debt.

For Australia, Oliver believes the 10-year bond yield could rise towards around 5.5% if the current pressures persist.

What it means for investors

For investors, rising bond yields can have broader implications for borrowing costs, valuations and financial markets. Persistent pressure on government bonds could also keep attention focused on inflation, government debt and the future path of interest rates.

The Australian 10-year yield already sitting at 2011 levels highlights how significant the current bond-market repricing has become. Whether yields stabilise or move towards the 5.5% level will depend largely on inflation trends, government borrowing and expectations for central-bank policy.
