Ray Dalio, founder of Bridgewater Associates, warns that the UK faces a potential “debt death spiral” as rising borrowing costs force the country to take on more debt to service existing obligations. Speaking to the Financial Times, Dalio highlighted the troubling combination of rising gilt yields, which touched 4.90% (highest since 2008), alongside a weakening pound and deteriorating economic data – a pattern that typically shouldn’t occur when monetary policy is expected to ease. The billionaire hedge fund manager points to a fundamental supply-demand problem in the gilt market, suggesting investors are becoming increasingly wary of absorbing UK government debt. This market behavior is particularly concerning as it comes amid cooling inflation and growth data, implying the market’s reaction is driven by debt sustainability concerns rather than economic strength. Dalio extends his warning to the US market, noting similar signs of strain in the Treasury market and urging the incoming Trump administration to prioritize addressing the American debt burden. The parallel challenges in both markets underscore growing global concerns about government debt sustainability in major economies.
