Was just alerted to this on Reddit and thought it worth sharing here.
The SPDR ETF (ticker ACWI) that tracks the MSCI All Country World Index had it's TER cut in August 2024 from 0.40% to 0.12%. Making it now cheaper than the iShares ETF that tracks the same index (ticker SSAC, and 0.20% TER) and the much loved Vanguard ETF that tracks the FTSE All-World (ticker VWRP and TER of 0.22%). All are listed on GBP/GBX.
Compared to the Vanguard ETF, that's 0.1% cheaper, for the MSCI ACWI index vs FTSE All-World index, which you'd struggle to split hairs between performance wise. Sure, it's ONLY 0.1% but hey, some might find this interesting/useful!
