March 2026 update – Review to 31st December 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 10%. International Fixed Interest and UK Equity are the net beneficiaries of reductions in allocations to Cash, Property, UK Fixed Interest and International Equity. These changes are driven by the amendments to the return and volatility assumptions of these asset classes.
Assumption Changes
The allocation changes are driven by a 0.21% reduction in the return assumption of UK Fixed Interest and an increase of 0.05% for International Fixed Interest. This has resulted in a rotation out of UK Fixed Interest into International Fixed Interest.
To balance the impact of the lower volatility of the International Fixed Interest on the portfolios, the optimiser has reduced exposure to Cash and Property. The greater reduction in international equity returns resulted in a reallocation of exposure to UK Equity.
