The Japanese yen just dropped fast to 160 per US dollar, and even seasoned investors are scratching their heads.
Usual clues like interest rates aren't working, as mixed economic signals and money flowing out of Japan keep the currency jumpy.
Even after Japan's government spent a record 27.1 trillion yen trying to steady things, the yen's path is still uncertain.
Yen selling persists amid BoJ hikes
Japan's central bank has raised rates, but they're still lower than in other big economies, so people keep selling off yen.
On top of that, lots of Japanese money is being invested abroad, adding to the chaos.
With all these changes and more foreign investment coming in, many traders are just waiting it out to see what happens next.
