Latest asset allocation quarterly reviews

September 2025 update – Review to 30th June 2025

The latest Willis Towers Watson (WTW) parameter review of the economic assumptions underpinning our platform’s optimised portfolios, has resulted in changes to asset allocations this quarter, with an average portfolio turnover of approximately 7%. As asset allocations remained unchanged in the previous quarter, all comparisons are made against the prior review as of 31 December 2024.

Although shifts in return assumptions continue to be the main driver of reallocations, this quarter additional factors—particularly those affecting the Property asset class—are also influencing these adjustments.

Assumption Changes

The assumptions figures are set with a 10-year time horizon and incorporate both short- and long-term (30+ years) perspectives. They are also built on a cash plus a risk premium basis. This quarter, the assumption for Cash decreased contributing to reductions in return assumptions for UK Fixed Interest , UK Equity , and International Equity. The differing degree of change between International Equity and UK Equity have prompted a reallocation from International Equity to UK Equity.

WTW has also raised the volatility assumption for Property due to increases in the beta of REITs to Global Equities, making this asset class less attractive. However, this was partly offset by a lower ongoing cost assumption for property, following an internal review.

With that latest assumptions, International Fixed Interest also sees its first allocation in more than a decade within these models, specifically across Risk Levels 2-5. This reallocation is at the expense of the cash and property asset classes.
