I took this into account when deciding where to invest.
There are some very reliable UK based companies that pay good dividends. Shell, BP, Legal and General, Aviva, National Grid, most utility companies etc to name a few.
I can’t see FT implementing what is said here as there are good alternatives already…
Invest in UK dividend paying stocks, accept the FX fee on US stocks, or open an account with a brokerage in US currency.
