Thanks JPD
If you bought into an ETF with a base fund currency in GBP, doesn't that mean you're exposed to currency rates when you sell out later though?
So if the ETF increases in value by 10% but the GBP also increases in value against the Euro by 10% that then cancels out your gains (as you cash out in Euro)?
The buy price at the moment for iShares FTSE 100 on LSE is £5.68 while on Euronext is €6.44 which is at the interbank rate I think, so I'd have thought buying the Euro ETF works out cheaper as you don't pay to buy the Sterling..
