Karine Pacary, Managing Director at Monterey Insight commented:
“We are pleased to share the latest results of the UK fund industry in the 8th edition of the Monterey Insight UK Fund Report 2025. By the end of 2024, UK regulated fund assets reached $2,886.7 billion, driven primarily by a strong 9.8% growth in equity funds. Equities remain the dominant asset class, reinforcing their central role in the market’s expansion following last year’s double-digit growth of 15%. Growth in 2024 was further supported by product innovation, with ACS structures leading organic expansion, posting the strongest growth among product types. Together, the continued strength of equities and the momentum in ACS underline the key forces shaping the UK regulated fund landscape.”
