Isio has published its latest quarterly report on the investment performance and asset allocation of 12 major UK Defined Contribution (DC) Master Trusts providers, revealing that recent tariff-driven market volatility has prompted a growing number of providers to reassess US equity allocations.
The end to US exceptionalism
The Liberation Day tariff announcement at the start of Q2 sparked a sharp equity sell-off as investors moved into safe-haven assets. Markets rebounded quickly when most tariffs were suspended, but volatility highlighted ongoing risks for DC schemes heavily weighted to the US market.
In Q2, more providers reduced their US allocations, reflecting concerns over tariff uncertainty, potential dollar weakness, and concentration in a small number of richly valued mega-cap growth stocks. While the US continues to dominate global indices, its weighting is significantly higher than its share of world GDP, prompting a broader reassessment of strategic equity exposures.
Despite the initial turbulence, growth phase portfolios recovered strongly as equities bounced back. There is value in the discussions emerging this year around growing scrutiny of US exceptionalism and its implications for strategic equity allocations over longer timeframes. But it is important to remember that members who are decades from retirement benefit most from long-term investment discipline and reacting impulsively to short-term shocks risks undermining compounding returns.
At-retirement phase diversification proves its worth
All the retirement-phase strategies Isio assessed delivered positive returns in Q2. Despite material differences in asset allocation, performance was clustered within a narrow range, underlining the resilience of diversified portfolios in volatile conditions. The most diversified at-retirement strategy recorded the strongest performance, demonstrating the value of spreading risk appropriately to protect members’ outcomes.
Sukhdeep Randhawa, Director at Isio said: “This quarter has been a reminder of two key principles for DC investing: don’t panic in the growth phase and diversify appropriately in retirement. While tariff turmoil sparked short-term market shocks, the bigger picture is that providers are now reconsidering how much reliance they place on US equities over the long-term. For members, it is clear that strategies built for discipline and diversification remain best placed to deliver resilience and long-term value.”
