I think this is a clue as to why the pound was so weak late in the week. Everyone is heading to the sidelines to get a clear look at the virus and that meant closing out long GBP and short EUR positions; along with hefty, structural EUR/GBP shorts. We'll have a better idea if that was really the case with next week's data.

The rush to sell the yen in this week's data confounds me.
