Global equity markets have continued to climb to fresh record levels even as bond markets signal mounting concern over inflation, borrowing costs and the longer-term economic impact of sustained geopolitical tension, according to a report by the Financial Times.
The S&P 500 has surged to successive all-time highs in a tech-led advance driven largely by enthusiasm around artificial intelligence-linked companies, extending a rebound that began in early April following a temporary easing in Middle East conflict tensions. The rally has been particularly concentrated in a small group of large-cap technology and semiconductor stocks, reinforcing concerns about market breadth.
At the same time, government bond markets have moved sharply in the opposite direction. US long-term yields have climbed to their highest levels since 2007, reflecting investor expectations that persistent inflation pressures – exacerbated by elevated energy prices – could force central banks to keep interest rates higher for longer. The divergence between equities and fixed income has become one of the most notable features of recent trading.
Some senior investors now warn that the disconnect between asset classes may not be sustainable. Amundi chief investment officer Vincent Mortier said markets may be vulnerable to a correction, arguing that the speed of the shift in sentiment across equities contrasted sharply with more cautious pricing in bonds.
Bond market indicators are also flashing caution. Long-dated US Treasury yields have risen significantly in recent weeks, while measures of near-term inflation expectations have moved above multi-year highs, underscoring concerns that higher energy costs could become embedded in broader price pressures.
Despite this, equity positioning remains strongly bullish. A widely followed survey from Bank of America shows a sharp rise in fund managers overweight equities, while bond allocations have fallen to their lowest levels in years — a combination analysts say may increase the risk of profit-taking if macro conditions shift.
Market strategists also point to signs of increasingly stretched sentiment in derivatives markets, where options activity suggests investors continue to price in further upside despite rising interest rates and geopolitical uncertainty. Some compare current positioning to earlier episodes of exuberance driven by retail trading and momentum flows.
The divergence is particularly evident between the US and Europe, where energy import exposure and weaker growth expectations have left European equities lagging behind. Analysts say this underscores how concentrated the current global rally has become in US technology leadership.
While some investors argue that strong corporate earnings continue to justify equity valuations, others caution that the combination of elevated rates, high energy prices and geopolitical risk leaves markets vulnerable to a sudden sentiment shift.
For now, equities appear to be pricing in continued resilience, while bond markets are increasingly signalling caution – a tension many investors believe may eventually need to resolve through either a market pullback or a shift in macro expectations.
