Currencies are a mystery to me. Regarding, however, your elections within your retirement plan, I think you are too conservative. Your time frame is longterm since you are young. To me that argues for being 100% equities. I also think that it wouldn’t be irrational to put 100% in international stocks. My reasoning is that global growth is likely to be far stronger than US growth over the coming decade and beyond. Just my opnion.
