The Great Yield Reset: Global Yields Reach Post-Crisis Highs

This fortnight, we turn to the bond market, where the global cost of capital has reset to levels last seen in 2008, and where the mechanism driving it says more about the next decade of returns than any single central bank decision.

BGW's FOCUS POINT

The Bloomberg gauge of global sovereign yields rose to 3.72 per cent this week, its highest reading since the middle of 2008.

The move is global, which is the first thing worth noting.  Japan's ten-year touched 3 per cent for the first time since 1996, a milestone for an economy that spent a generation at zero. UK thirty-year yields reached their highest since 1998 and gilts at ten years hit levels last seen in 2008. French government bonds are at post-crisis highs and German bunds at fifteen-year highs. Australia's ten-year climbed 9.5 basis points to 5.18 per cent before extending to 5.22 per cent after Wednesday's GDP release, a level last seen in 2011.

In the United States, the ten-year sits at 4.8 per cent, its highest since January last year, and the thirty-year near 5.3 per cent. The two-year, the maturity most sensitive to the Fed's next move, rose six basis points to 4.4 per cent.

The immediate catalysts were straightforward. Federal Reserve chairman Kevin Warsh used his Jackson Hole address to talk tough on inflation, which markets read as a signal that US rates may rise as soon as this month. Traders now price close to a 70 per cent chance of a quarter-point increase, which would be the first US hike since 2023, and both Barclays and Société Générale revised their forecasts after the speech to include rises they had not previously carried. Days later, renewed US strikes on Iran pushed Brent crude above US$95, up more than 10 per cent in six days, reviving energy-led inflation concerns just as wheat and corn hit multi-year highs.

Why it is happening

Global artificial intelligence spending will approach US$1 trillion this year, and it is being financed with debt rather than corporate cash flow. The hyperscalers alone have raised US$220 billion in bonds in 2026, more than double last year's total, funding data centres and the compute behind the models.

Bond markets allocate a finite pool of capital from investors willing to lend for long periods. When a large new borrower arrives, it must outbid the queue already forming, which in this market includes the US Treasury funding a $40 trillion debt alongside every corporate and mortgage borrower in the economy. The technology sector is willing to outbid because the prize it is chasing justifies almost any coupon. As Matt King of Satori Insights has observed, borrowing on that scale, indifferent to its cost, lifts yields for everyone else and is likely to keep doing so for as long as equity markets keep validating the spend.

This is why it is worth separating the two forces at work. The Fed sets the front end of the curve, and one quarter-point move is close to noise. The long end is set by the balance of supply and demand for duration, and that balance has shifted structurally. The market is not waiting on a policy decision. It is repricing the scarcity of long-term capital.

That distinction also explains why intervention has had limited effect. Treasury Secretary Scott Bessent's August decision to at least double the size of long-dated bond buybacks moved yields for a single session, and the market has since taken the whole move back, with thirty-year yields returning to where they sat before the announcement. Buybacks change liquidity in a thin market. They do not change how much capital the world is trying to borrow.

The important qualifier is that all of this is happening alongside expanding corporate profitability rather than deteriorating fundamentals. S&P 500 earnings per share rose 53 per cent in the June quarter, and equity markets remain within a few per cent of record highs. This is a repricing of capital and there is a reasonable argument that yields are simply returning to historically normal levels for the good reason that global growth is improving. 

Where the borrowers are going

The most useful signal in all of this is what issuers are doing in response, because it tells you where demand for their paper actually sits.

They are diversifying away from the US dollar market. Alphabet raised a record $5.5 billion in Australia in August, the first kangaroo bond from a US technology giant since Apple's foray in 2016. The deal drew more than 200 investors and orders that peaked above $20 billion, and its spreads have tightened 5 to 10 basis points in secondary trading since, which is the market's way of saying it was priced generously. Amazon is widely expected to follow with a transaction of similar size, and market participants expect one or two further deals in the $3 billion to $5 billion range could be comfortably absorbed this year if adequately spaced.

Australia has become the third-largest corporate bond market in the world, behind only the United States and Europe. The reason is our $4.4 trillion superannuation pool, which represents precisely the long-dated, disciplined capital these issuers need, and which is not competing with the crowded queue that has formed in US dollars. The world's largest borrowers are increasingly keen to reduce their reliance on dollar funding, and Australian investors are the beneficiaries of that shift.

Central banks are moving in the same direction. The Reserve Bank has become the first G10 central bank to effectively confirm a reduction in its target US dollar reserve allocation, cutting it to 45 per cent from 55 per cent according to Deutsche Bank's reading of its 2025 annual report, with the balance shifted into euros. The euro now accounts for 30 per cent of Australia's foreign currency reserves. Assistant Governor Christopher Kent has been clear this is not a currency forecast and should not be over-read as one. But the direction is corroborated by IMF data and reserve manager surveys showing a broad intention across central banks to trim dollar exposure over the coming decade rather than accumulate it.

None of this signals the end of the US dollar's role. Its economy, its trading volume and the depth of its bond market are not replicable, and the dollar has still gained against a basket of currencies this year. What it signals is a gradual broadening, where capital seeks depth and discipline in more than one place, and where markets like ours are increasingly on the list.

The conclusion for investors is constructive. Capital is being redirected toward markets with depth and price-disciplined buyers, and Australia is one of them. Domestic investors are being courted, at attractive terms, by the highest-quality issuers in the world, and the yields on offer across fixed income now reflect a genuine return rather than a compromise.

A higher and more volatile risk-free rate changes both what a portfolio should own and what it should be paid to own it. It also opens access to issuers, structures and pricing that were simply not available to Australian investors in the previous cycle.
