Asset manager Rathbones has issued a stark warning that the introduction of a wealth tax under a new Labour leadership could precipitate a £100 billion exodus of capital from the UK.
The firm argues that such a fiscal move would be economically damaging, undermining growth, investment, and job creation as high-net-worth individuals seek to relocate their assets abroad.
The caution comes at a critical juncture for the UK market, following British Prime Minister Keir Starmer’s announcement of his resignation from both the premiership and the leadership of the Labour Party.
This departure has triggered a rapid succession process, introducing short-term volatility and uncertainty into the political landscape.
Investors are now assessing the risk that a new leadership team might pursue more aggressive fiscal policies, including the long-debated wealth tax.
Rathbones’ analysis suggests that the threat of a wealth tax is not merely a political talking point but a tangible risk to the UK’s economic stability.
