A surge in investment linked to AI computing infrastructure, combined with persistently elevated long-dated government bond yields worldwide — including the 10-year US Treasury yield — is prompting Pacific Investment Management Co., or Pimco, one of the world's largest fixed-income investment giants, to turn its attention to how well the Australian economy can withstand high interest rates and high yields.
Adam Bowe, the senior portfolio manager who heads Pimco's Australian operations, argues that both institutional and individual investors are being far too aggressive in pricing further rate hikes from the Reserve Bank of Australia. He stresses that the data center investments that AI giants such as Amazon, Microsoft and OpenAI continue to expand in Australia can support part of economic activity as well as rising financing costs. The fund manager also says that rising unemployment, a cooling property market and household debt-servicing pressure in Australia could significantly limit any extension of the central bank's tightening cycle.
As a result, with the Australian 10-year government bond yield climbing to its highest level since 2011, Pimco believes that 5- to 10-year Australian bonds already offer solid absolute yields and relative allocation value, and it wants investors to seize in advance the price-recovery opportunity in Australian government bonds that would come from a sharp pullback in what it considers overly aggressive rate-hike expectations.
During the midday session of Asian trading on Monday, September 28, global government bond markets were still under heavy selling pressure in long-dated debt. The 10-year US Treasury yield hovered near its highest level since 2007 and briefly climbed to 5.215% during Asian hours, while comparable Australian and Japanese government bond yields hovered around 5.41% and 3.10% respectively, with the Japanese 10-year yield hitting its highest level since 1996. Japanese 20-year and 30-year yields also reached their highest points in more than three decades. On September 18, the Bank of Japan decided to raise its policy rate from about 1.00% to about 1.25%, explicitly noting that high oil prices, a weak yen and AI-related demand are pushing up corporate costs, with some of that pressure beginning to pass through to consumer prices, while wage pass-through and inflation expectations are also strengthening.
Behind this round of rising long-dated government bond yields worldwide is a combination of energy inflation, policy-rate expectations and debt supply pressure closely tied to the AI infrastructure buildout. Trump's rejection of Iran's latest proposal to reopen the Strait of Hormuz has kept supply uncertainty weighing on oil prices; during Asian hours on September 28, Brent crude rose to about $106.31. Expanding financing needs from governments and AI companies have further intensified the competition for global savings. The direct catalyst and driver of this global bond market adjustment is arguably the market's reassessment of when energy supply will recover and how much more the Federal Reserve will need to raise rates. For the 10-year-and-longer US Treasury curve, an even more critical structural force is the competition for the global pool of duration bond capital from "rising fiscal deficits plus AI debt issuance."
Pimco Sees Optimistic Investment Value in Australian Bonds, Says Market Has Overpriced Rate Hikes
Pacific Investment Management Co. is becoming increasingly positive on Australian sovereign bonds, which have suffered depressed price performance in recent years, believing that against a slowing local growth trajectory, the market has gone too far in pricing rate hikes and that aggressive rate-hike pricing is seriously misaligned. Adam Bowe, the senior portfolio manager who heads Pimco's Australian operations in Sydney, says Australia's hiking cycle is already "fully priced in" by the market, and key cracks in the economy are starting to appear. In an interview with media on Monday, he said this makes Australian bonds look uniquely attractive, especially the 5- to 10-year intermediate-to-long segment of the yield curve. "Australian bonds are attractive in and of themselves, and also relative to other markets," Bowe said. The Fed and the RBA "are both trying to get inflation back to target while avoiding damaging the economy, but I think the cracks in the economy here are more obvious," he said in the interview.
Pimco's judgment comes as domestic Australian indicators show growth momentum weakening significantly, most notably with unemployment near a five-year high and the housing market, which is crucial to the economy, slowing. With Australia's benchmark 10-year government bond yield rising to its highest level since 2011, this moment offers investors an entry point to capture a market bottom. As shown in the chart above, the Australian 10-year government bond yield is at its highest level since 2011. Since the middle of this year, Adam Bowe has been bullish on Australian bonds because he expects the RBA will eventually be forced to pivot to rate cuts to support a cooling economy.
Still, short-term monetary tightening risk remains high and could push Australian short-dated government bond yields even higher. Traders broadly expect the RBA to raise rates when it concludes its two-day policy meeting on Tuesday, pushing the cash rate to its highest level since November 2011, with another hike possibly announced in November. The latest interest-rate swap data compiled by Bloomberg Intelligence shows that the market sees a stunning three-in-four probability of two more hikes next year, which would push the benchmark rate above the key 5% milestone for the first time since 2008. However, the top global fund manager from Pimco believes the Australian domestic economy cannot withstand such an aggressive rate path. Bowe warns that while data center capital spending may keep the economy resilient over the next two years, indebted Australian households have a deeper "structural fragility." He stresses that the share of income going to taxes and mortgage repayments is already near record highs, making it hard for consumers to bear a 5% cash rate.
"The more they tighten, especially if rates go to around 5%, I think the risk of a deep domestic recession in Australia is real," Bowe said. Given that yields are already attractive and growth is showing signs of slowing, "I have a positive view on the outlook for Australian bonds," he stressed in the interview.
Poor "Rate Tolerance" Emerges: Computing Power Still Needs to Expand, but Australian Household Cash Flows Are Tested First
Undoubtedly, financing demand linked to AI infrastructure worldwide has not cooled significantly, which is why tech giants such as Google parent Alphabet and Amazon have begun eyeing the Australian dollar-denominated government bond issuance market. Media previously cited LSEG data on September 1 showing that Alphabet, Amazon, Meta, Microsoft and Oracle had issued about $220 billion of debt that year, more than double the full-year 2025 scale; on September 22, it cited a Goldman Sachs forecast that total debt issuance by hyperscale cloud providers could reach a record $420 billion in 2027. The latest example is SoftBank: it has finalized terms for a bond offering of about $11.1 billion, expected to be issued on September 29, including $4.5 billion of 7.5-year dollar bonds with a 9.75% coupon, with proceeds mainly used to pay for follow-on investment in OpenAI and for general corporate purposes. Strong financing appetite and markedly higher funding costs are occurring at the same time.
From an engineering and investment perspective, intelligent agents expand a single question-and-answer exchange into planning, retrieval, tool execution and repeated verification, increasing demand for model calls, CPU task execution, memory state preservation and storage access; when the scale of users and tasks expands faster than per-task efficiency gains, computing infrastructure still needs to be expanded. Yet demand growth does not automatically translate into improved investment returns: the cost of new financing depends on the benchmark rate for the corresponding tenor, credit spreads and financing terms, while construction delays can lengthen the gap between capital outlay and revenue realization. The rise in the 10-year US Treasury yield, the "anchor of global asset pricing," on the one hand raises the benchmark cost of long-term financing and refinancing, and on the other hand raises the return rate required for equity valuations, making the market focus more on whether AI companies' profit growth can be converted into free cash flow.
This divergence can essentially be summarized in Australian financial markets as "poor rate tolerance" — that is, AI investments that secure orders and capital support may continue to bear higher financing costs, while indebted households will first respond to repayment pressure by cutting consumption. Data from the Reserve Bank of Australia in August showed that planned mortgage and consumer credit repayments in the second quarter were already close to 12% of household disposable income, nearing the 2024 peak. Pimco's contrarian allocation logic thus becomes increasingly valid: if consumption and employment weaken further, forcing the actual rate-hike path below market pricing, 5- to 10-year Australian bonds could simultaneously deliver record-strong interest income and dual capital gains from falling yields.
