Cutting cash Isa limit will not boost stock market, MPs warn Rachel Reeves

Treasury committee says move in November budget could push up mortgage rates instead

Cutting the annual cash Isa allowance will not encourage many savers to switch to shares but could push up mortgage costs, MPs have warned the chancellor.

Adults can put up to 20,000 a year in a tax-free Isa and spread the money between cash and stock market investments as they choose. In the 2023-24 tax year, 66% of all contributions went into cash savings.
