When Bonds Speak, Should Equities Listen?
Global bond markets remained centre-stage, with 30-year US Treasury yields pushing through to a 19-year high. In isolation, yields are not especially elevated from a long-term perspective, but markets rarely react to levels; they react to speed. And the pace of this recent move has been enough to unsettle investors.
That matters because bond yields are, in effect, the price of money. When the price of money moves sharply higher, it doesn’t stay contained to the ‘fixed income world’, but feeds directly into borrowing costs across the economy for businesses and individuals, and, crucially, into valuations underpinning equity markets.
Against that backdrop, the Federal Reserve finds itself in an increasingly uncomfortable position. Minutes from the latest FOMC (Federal Open Market Committee) meeting hinted at a growing willingness to abandon an easing bias altogether, with some policymakers acknowledging that rates may yet need to rise before they can fall.
What stands out from a strategic perspective is the growing disconnect between bonds and equities.
Bond markets are signalling tighter financial conditions, higher discount rates, and greater fragility in the system. Equities, by contrast, are pushing higher, seemingly unfazed. In fact, the latest Bank of America Merrill Lynch global fund manager survey, reflecting approximately $1 trillion of assets being actively managed, showed the largest increase in equity allocations on record in April.
That divergence would be notable at any point in the cycle. It becomes more acute when considering valuation. The cyclically adjusted P/E (price to earnings) ratio for US equities is now approaching levels last seen during the peak of the dot-com bubble. It is, in a historical context, an unusual combination.
Overlaying all of this is a subtle but important shift in investor behaviour. For much of the past decade, markets rewarded companies exhibiting capital discipline through consistent shareholder rewards in the form of dividends, buybacks, and improved operational efficiency. Today, they are increasingly rewarding capital investment, even at the expense of cash flow.
The AI boom is leading this change in sentiment. Large-scale capital expenditure, particularly in data centres and semiconductor infrastructure, is now being viewed not as a risk, but as a necessity. And in doing so, it is altering the balance of risk across the capital structure: what is good for equity holders is not necessarily good for bondholders.
That tension is perhaps best captured in Nvidia’s results midweek.
The company delivered exceptionally strong results, including around 85% sales growth and operating margins of over 60%, yet its share price fell modestly as expectations had already been set extremely high. Even significant announcements such as a substantial share buyback programme failed to fully satisfy investors.
This reaction highlights how demanding current market expectations have become, particularly for companies seen as central to the AI build-out.
More broadly, equity markets continue to be driven by a narrow cohort of winners. Semiconductor stocks remain the epicentre of the rally, pushing both the sector and the wider S&P 500 to fresh all-time highs. The elevation of companies such as Micron and SK Hynix, key players in the AI hardware supply chain, towards trillion-dollar valuations underlines just how concentrated this leadership has become.
If AI delivers on its promise, these valuations may, in time, look justified. But that “if” is doing a lot of heavy lifting.
Running quietly in the background, but with the potential to move quickly to the foreground, is geopolitics.
The lack of resolution around the Strait of Hormuz continues to hang over markets. While commodity prices have not yet fully reflected the risk, the situation remains fragile. Any meaningful escalation would have immediate implications for energy markets and, by extension, inflation expectations.
For now, markets appear willing to look through these risks, and equities continue to lean into the optimism of AI-led growth, while conversely bond markets quietly question whether the foundations beneath that optimism are beginning to shift.
