Mr. Peter Boockvar，很有見解和觀點的經濟學家認為日元大跌背後的原因：

Japan's Big Sell-Off, Mr. Peter Boockvar on What's Driving It:

1. The unwind of the Yen carry trade has been massive;

2. Reflects an epic build up in leverage over the past year;

3. The BOJ  waited way too long in raising rates and trimming QE;

4. Would buy Japaness stocks on the market crash.
