Rising long-term US Treasury yields are fundamentally reshaping the global financing landscape. With dollar funding costs climbing, alongside surging demand driven by artificial intelligence investment fever and government fiscal deficits, a growing number of international issuers are exploring alternatives beyond the US dollar.

In recent years, from "kangaroo bonds" to "panda bonds," Asia-Pacific debt markets denominated in currencies like the Australian dollar and Chinese yuan have evolved from relatively peripheral funding channels into crucial platforms for global corporations and sovereign issuers seeking to diversify their funding sources.

A Pivotal Turning Point

US tech giant Alphabet Inc. recently raised A$5.5 billion through its inaugural Australian dollar bond issuance, marking another example of global technology firms broadening their financing avenues. Term sheet data revealed that investor bids for the A$5.5 billion offering exceeded A$18 billion. Alphabet has become the first AI hyperscaler to enter the Australian dollar debt market, and the first major US tech company to issue such bonds since Apple Inc. launched its "kangaroo bond" back in 2016.

It's not just tech behemoths competing for capital worldwide. According to recent reports, foreign borrowers are pouring into what were once relatively niche Asia-Pacific bond markets amid heightened uncertainty and record borrowing volumes. This year alone, Commerzbank AG, French energy firm Engie SA, Henkel AG & Co. KGaA (owner of the Persil brand), Singapore Airlines Ltd, and the Portuguese government have all made debut issuances in Australian dollar or yuan-denominated bonds.

Data from the London Stock Exchange Group (LSEG), tracking international bond transactions through the end of July, shows foreign issuers have sold approximately A$60 billion worth of "kangaroo bonds" this year, representing a roughly 40% increase compared to the same period last year. Additionally, according to Goldman Sachs Group Inc., issuance of Chinese "panda bonds" and "dim sum bonds" (yuan-denominated bonds issued in Hong Kong) reached record levels of approximately RMB 160 billion and RMB 350 billion respectively in the first half of this year, surging over 60% year-on-year, with about half coming from international borrowers.

Carla Good, Head of Asia-Pacific Debt Syndicate at HSBC Holdings plc, noted: "Asia-Pacific bonds have reached a turning point. These markets are hugely significant for local companies and are becoming increasingly indispensable for international firms. Financing options of this scale were simply not available a few years ago."

Magnet for Global Capital

The artificial intelligence investment boom and persistently high government fiscal deficits are driving escalating financing demand across the US and global markets. According to LSEG data, global international bond underwriting sales surpassed a record US$4 trillion by the end of July this year, compared to approximately US$3.5 trillion during the same period last year. This surge in funding needs has intensified competition for capital in traditional bond markets.

Falt, Head of Debt Capital Markets Syndicate for Europe, Middle East and Africa at Mizuho Financial Group Inc., observed that as tech giants flood traditional borrowing markets, competition for capital is intensifying, prompting bankers to advise clients to act early and diversify their funding sources. Against this backdrop, both issuers and investors are seeking alternatives beyond the dollar market. Falt noted that Asian investors and central banks, previously focused on dollar bonds, are now rotating into non-dollar denominated instruments like Australian dollars and Hong Kong dollars, further boosting demand for these markets.

The high-interest-rate environment is accelerating this trend. As long-term interest rates in the US and Europe continue to climb, dollar and euro funding costs are under corresponding pressure. Recently, the US 30-year Treasury yield briefly surpassed 5.3%, hitting its highest level since 2007, while Germany's benchmark 30-year bund yield rose to a 15-year peak.

Pan Xiangdong, Chief Economist at Qilai Research Institute, explained that soaring long-term rates in the US and Europe have significantly pushed up dollar funding costs, prompting global issuers to proactively shift toward Asia-Pacific local currency markets with relatively lower interest rates and more stable exchange rate trajectories, such as the yuan and Australian dollar markets. Meanwhile, the sustained growth of overall financial wealth in the Asia-Pacific region—such as the rapid expansion of domestic institutional assets like Australian superannuation funds—is providing ample local demand for the region's bond markets. Pan also mentioned that economies like China have, through capital account management, effectively blocked the direct transmission of external interest rate volatility, helping maintain relative stability in domestic bond markets and further enhancing their appeal as a "safe haven" for global capital.

Diversification Becomes a Long-Term Trend

Within this broader shift, China's yuan bond market is emerging as a key destination for overseas issuers looking to tap into the Asia-Pacific financing landscape, with the rapid growth of "panda bonds" drawing particular attention. Pan believes foreign companies issuing yuan bonds in China are attracted not only by the cost advantages of yuan financing, but also by a combination of factors including exchange rate stability, business alignment, and expanding their investor base.

Commenting on the global financing trend reflected in this surge, Pan emphasized that this represents a structural diversification of funding methods rather than simple de-dollarization. He stressed that the dollar funding market still maintains a dominant and massive position globally, but the current new trend indicates that global issuers are actively constructing multi-currency financing portfolios encompassing the yuan, Australian dollar, and Hong Kong dollar. The goal is to reduce over-reliance on the interest rate fluctuations and liquidity risks of a single currency, particularly the US dollar.

Pan views this as an adaptive adjustment within the global financing system, set against the backdrop of a structurally higher US Treasury yield curve and persistently increasing geopolitical uncertainty, with risk diversification as the core underlying logic. Looking ahead, Pan predicts the market will move toward a pattern where differentiation and deepening proceed in parallel. Specifically, markets with stable interest rate differentials, ample liquidity, and solid macroeconomic fundamentals—such as the yuan bond market—will further consolidate their financing positions regionally and even globally. Conversely, some smaller markets may experience increased volatility due to rapidly shifting supply-demand dynamics.

Overall, Pan concludes that financing diversification will become a long-term structural trend, though the process will be gradual and punctuated by setbacks.
