What is up with the YEN?

I am trying to find the news that moves all currency pairs with then Yen! It seems like the trend started to get momentum around 12:30 AM. But I don’t see any news for Japan at that time. I like trading with the news. Trying to get familiar with the fundamentals and economics with trading and get a better understanding if anyone can help please let me now thank you

It started off with BOJ’s announcement last Fri for implementing QE. Over the weekend, everyone realized that this must mean that even the Japanese have lost faith in their ability to recover. Right now, it’s a fire sale.

trying my hardest to get better understanding with technical and fundamental analysis. just need to keep at it and ill eventually get it and thank you by the way
