UK equity funds suffer £601m net outflow in August as Budget tax-hike fears drive investors into cash and bonds
Investors pulled a net £601m from UK stock funds during August, according to the latest Fund Flow Index from global funds network Calastone, pushing a broader £315m net outflow across all global equity strategies. The August retreat marks the fourth consecutive month of net selling globally and the fourteenth month of equity outflows in the past fifteen. Since June 2025, investors have collectively pulled £15.16bn from equity funds. European stock funds registered £145m of outflows, while North American funds lost around £3m. Fixed-income instruments benefited from the rotation, attracting inflows as investors sought shelter. Edward Glyn, head of global markets at Calastone, pointed squarely at Budget uncertainty as a compounding factor in the UK specifically. Chancellor John Healey, in a speech on Monday 7 September, declined to rule out tax hikes at the forthcoming October Budget on multiple occasions. Glyn noted that if investors believe capital gains and pension tax breaks are at risk, some have an incentive to act before the Budget rather than wait. Healey is also facing pressure from a global bond sell-off that has sent UK borrowing costs higher. Some economists have forecast that the Chancellor's remaining £23.6bn of fiscal headroom could be slashed in half by pressure from rising gilt yields. The convergence of domestic tax uncertainty and global bond market stress is intensifying caution across retail and institutional investors in UK equities.
Why this matters
Fourteen months of near-continuous outflows from equity funds represent a structural shift in UK retail investor behaviour, not merely a cyclical blip. The explicit link between Budget speculation and accelerating outflows shows that tax policy uncertainty is now a live drag on UK capital markets, compressing valuations and dampening the appeal of London-listed equities at precisely the moment the government wants growth. A sustained withdrawal of equity capital raises medium-term concerns about the health and depth of the UK listed market, making it harder for companies to raise equity at competitive prices relative to US peers. The compounding pressure from rising gilt yields narrows the Chancellor's room for manoeuvre and creates a feedback loop: fiscal uncertainty drives outflows, which depress equity values, which in turn reduce tax receipts from investment gains.
On the Ground
Capital markets and tax practices at City firms both see increased demand here: equity capital markets (ECM) teams face a more challenging fundraising environment for UK issuers, while tax advisory teams are fielding urgent client queries on capital gains tax and pension tax relief exposure ahead of the Budget. Funds lawyers are monitoring the asset allocation shift toward fixed income, which may generate work on bond fund documentation and structured product design. A trainee on a capital markets matter in this environment would assist with prospectus drafting and verification notes for any issuer still pressing ahead with a UK listing, and would be involved in pricing supplement reviews and PDMR (person discharging managerial responsibilities) notification letters where share-based remuneration packages are being reassessed in light of potential CGT changes.
