As I watched this morning over a cup of coffee, big drop below 1.22. Looks like some attempts to support it at 1.219 but this is the first drop below 1.22 in two years, and except for that other low, the lowest it's been in 8 years, since the euro build-up. A drop below 1.20 would indicate a significant loss of faith in the thing. It's on the edge.
7/24 Update - continues to trend down, as one might expect in the absence of major intervention. Eventually the flight to other assets could be unsupportable by Fed buying Euros with USD as even the Fed might not want provide that much support for Euro.
