When I first created this I just couldn't believe what I was looking at.

Notice all currencies are against the US$, so lines going down mean the US$ buys less of the currency, and lines going up means the US$ buys more of that currency. !!!

Note that these are year averages, so they do not contain sharp changes or recent changes.

And just to show I have the pairs the right way round.
You have to invert some of these to get US$xxx, and compare the red lines changes with my chart. I think they match.

Given the reduction in purchasing power of the US$, to me that seems kinda significant!
