habanero - Do those American and European mutual funds pay dividends in their respective currencies? Do you have USD and Euros from December dividends?
Yes and no, the funds own the actual shares so they receive dividends in whatever currency the share paying out is listed in and it gets reinvested automatically. For tax reasons historically distributing funds have never really been a thing here and afaik there isn't a single one from the local providers where you actually receive the dividends. So apart from buying and selling there is no cashflow. Until very recently for individuals dividends where taxed as capital income the year you receive dividends, while dividends that got reinvested by the fund was not taxed. You only pay capital gains tax when actually selling and realizing a profit so it obv made no sense to have a fund distribute dividends as reinvestement means deferring taxes for a very long time and adding to the compounding. Now the tax rules have changed, but the funds haven't. I could probably buy a distributing fund from an international provider, but I haven't looked into it as it is of no interest for me personally. So the funds basically track the total return version of the index.
So for both funds I own the value is in domestic currency, when I buy I use domestic currency and if I were to sell I wold receive domestic currency. But as the actual holdings in the funds are international (they track the MSCI World Index) I have FX exsposure in the non-hedged fund.
So for example's sake, say the S&P 500 is unchanged from Jan 1st til 31 dec. 2% dividends where paid out by the index constituents. Assume 0 fees.
1 Jan I invest 100 in my domestic currency in an S&P 500 tracking fund from a local provider, 8 units of domestic currency equals 1 USD at the start of the year, but 9 at the end of the year ( so weaker vs USD)
At the end of the year the hedged fund would be worth 102 in domestic currency (unch index but 2% dividends during the year).
At the end of the year the unhedged fund would be worth 102 * 9 / 8 = 114.75, reflecting the weakening of my domestic currency vs USD so measured in domestic currency my USD-denominated investments are worth more.
In reality it's a bit different as the hedged version has a 0.05% higher management fee, but you get the drift.
As a citizen of a tiny country with a tiny currency you can argue for various degrees of FX hedging as your expenses are local but a lot of stuff is imported, you travel abroad and so on. I'd say that 0% is probably wrong and so is 100%, I have settled for roughly 50/50 with some opportunistic view on which one I buy at any given time. This march/april our local currency got abseloutly hammered, by so much that the non-hedged fund barely fell in value despite world markets tanking hard. At that time, almost all my buying was in the hedged version as I assumed the currency would recover from its very wild ride, which it also did to a large extent. The same happened in 2008/2009 for that matter. As long as I aim to keep the split at around 50/50 I will in practice buy the "cheaper" one most of the time - I don't rebalance by selling one and buying the other so the 50/50 is a rather soft target in that respect.
