Hey @citricut,
@ hedging: the long term passive investor typically does not bother for hedging, as hedging only gives a very short term protection <<1year, unless he does it himself. then he is effectively market timing.
proper diversification among currencies is the only real response i can think of. also consider that this fund probably has some 50% US-denominated assets, the rest may be something else (i.e. EUR). Regardless of the whole ETF being in USD, their numerical value in USD would rise according to the devaluation of the Dollar. Therefore only that fraction of the ETF is exposed to USD current risk that is actually USD-based.
I can forward you to my own and other’s portfolios. In my case, even though 80% are traded in USD, only 30% of the underlying assets are US-based. I will add some EUR-exposure once the absolute value of my portfolio increases a bit
