Currency changes - from the Canadian tariff to Brexit & the French election:
Bottom Line: If you have a long list of desired international destinations you'd like to visit, it's been worthwhile to play the currency game in recent years. Once upon a time wild swings in major currency values didn't occur with any regularity (within the developed world economies). In recent years there's pretty much always a currency or two that's a specially good value relative to the US dollar. Today the Euro isn't as good of a value as it had been.
On back of the pro-Euro Macron winning the French Presidential election - the Euro has reached a six month high against the US Dollar. That being said there's currently a better value proposition if you're traveling to England or Canada as those currencies remain weaker against the US Dollar currently.
