At Commonwealth Bank’s annual global markets conference in Darling Harbour, a central discussion focused on the potential ceiling for long-term bond rates. A London-based hedge fund manager offered a confronting view, suggesting 10-year bond rates could reach 7 per cent. This projection is grounded in historical real interest rates from the 1990s and current inflation, indicating that global bond rates between 6 and 7 per cent are plausible. This outlook is reinforced by expectations that global capital expenditure, particularly in artificial intelligence and energy transition, shows no signs of slowing down.
The increasing influence of hedge funds in fixed-income markets, driving short-term price movements and government financing, was a key observation. Another major theme was the escalating competition for capital from “hyperscalers” like Alphabet, Amazon, Meta, Microsoft, and Oracle. These tech giants are issuing billions in debt to fund their artificial intelligence ambitions and build cloud infrastructure. As price-insensitive borrowers whose investment returns vastly exceed debt costs, they are undeterred by rising interest rates. This effectively crowds out other borrowers, leading to higher borrowing costs for governments, corporations, and households alike.
This aggressive funding strategy by hyperscalers presents a considerable challenge for central banks, including the Reserve Bank of Australia. Should these companies continue to raise substantial capital in bond markets despite higher interest rates, it could jeopardise central banks’ ability to use monetary policy to manage economic demand. Institutional investors, while benefiting from AI-driven equity returns, are also navigating the potential second-order effects. The immense valuations of some AI firms suggest a looming threat to established listed companies. Moreover, bond markets currently offer attractive returns, with corporate bonds yielding around 9 per cent, yet many investors continue to pursue yield in riskier assets such as private credit.
