Do you have any evidence that they’re subsidizing US customers? It’s possible the fees are higher in the UK due to it being more expensive to operate the funds.
Investors in the UK are not partners in Vanguards mutual structure, and Vanguards UK platform ("Vanguard Investor") is not run by Vanguard but by a third party (FNZ, a New Zealand fintech).
OCF for VT, a global equity index ETF in the US, is 0.06%
UK equivalent (the Global All Cap Index Fund, or perhaps the VWRP All World ETF) is 0.23% and 0.19% respectively, and the latter excludes small caps and both have fewer holdings than VT
Invesco's All World ETF in the UK, tracking the same index is 0.15% and HSBC have an index fund tracking the same index also at 0.13%
Vanguard UK have a 0.15% platform fee whereas the best UK alternatives are completely free.
Vanguard UK recently introduced a minimum nominal platform fee on top which screwed over small investors.
Vanguard are no longer cheap and not on our side.
Mutual funds are cheap and have no tax disadvantages for us. In fact, outside of tax sheltered accounts, mutual funds are a lot easier to manage for tax purposes.
No, Vanguard just think it's fine to charge us 4x as much
VWRP, which I mentioned, is also an ETF
