Global bond yield surge reflects capital competition, Goldman says

Should Goldman be correct that elevated yields point to a structural need for capital rather than a temporary inflation scare, then long-dated bond pressure may persist, keeping term premiums elevated across developed markets. For equities, the implication is that index-level strength hinges heavily on earnings, so any letdown from AI-linked leaders could expose valuations that have already tightened. Rising Japanese yields have implications beyond Japan, because higher domestic returns can pull home investors back from overseas and support the yen. Australian and UK bonds, which already stand above 5%, mark the high-yield end of the developed world, potentially supporting the Australian dollar and sterling on carry grounds. Higher government borrowing tied to energy security also connects the bond narrative to oil, as elevated energy costs feed both fiscal needs and inflation risk.

Governments and AI builders alike are queuing for funding, and Goldman Sachs contends that higher yields are simply the price investors demand to stand in that line.

In summary:

• Goldman Sachs says higher government bond yields have become the global norm, with 10-year yields rising in every major developed market this year.
• Since January, 10-year yields have advanced by around 100 bps in Japan, about 85 bps in the US and near 80 bps in both the euro area and the UK.
• UK and Australian 10-year yields are above 5%, while Japan's is close to 3% after years of negative rates.
• The bank attributes the move to intensifying competition for capital, as governments borrow for defence, energy security and infrastructure and companies raise record sums for AI infrastructure and data centres.
• Goldman says picking well now matters as much as market exposure, with bonds once again a genuine source of return but not always a dependable hedge for stocks.
• The bank says S&P 500 forward valuations have drifted toward April's lows even as the index trades near record highs, with strong earnings, particularly in AI-linked names, masking the pressure.

Goldman Sachs says higher bond yields have become a global norm, arguing that growing competition for capital, rather than a temporary shock, explains why borrowing costs have climbed across every major developed market this year.

In a research note, the bank highlighted the breadth of the shift. Since January, the 10-year government bond yield has climbed by around 100 basis points in Japan, about 85 basis points in the US and close to 80 basis points in both the euro area and the UK. Goldman said five of the six markets it tracks recorded their highest monthly average yield since at least 2019 in September. UK and Australian 10-year yields are now above 5%, while Japan's is approaching 3%, a notable shift for a market where yields sat below zero for years.

The bank's explanation revolves around demand for funding. Many governments are borrowing more to fund defence, energy security and infrastructure, while companies are raising record amounts for AI infrastructure and data centres. Goldman said these combined needs are boosting demand for capital, and investors are demanding greater compensation to lend. In the bank's framing, higher yields are simply what that competition looks like in practice.

That environment, Goldman argues, favours discrimination over broad exposure. The bank describes selectivity as the new source of excess return, saying that picking well now matters as much as simply being invested. Higher starting yields have restored bonds as a genuine source of return, Goldman said, although they may not always offer a dependable hedge when stocks fall. Among equities, the bank sees companies that can fund their own growth, or that earn more than their cost of capital, as potentially better positioned.

Goldman also flagged what it sees as rational behaviour in equity valuations. The forward multiple on the S&P 500 has drifted back toward the lows seen in April, even as the index trades near record highs. In the bank's view, strong earnings growth, particularly among AI-linked companies, may be masking the valuation pressure that higher yields would otherwise put on share prices.

The implication is that equity strength is increasingly reliant on earnings delivery. If yields stay elevated and profit growth slows, the cushion that has protected headline index levels could thin, leaving investors more exposed to the gap between rising financing costs and corporate returns.
