It is indeed an explanation that the Japanese yen has the same function as the US dollar as a "safe haven currency". However, the relationship between the yen and the Nikkei index and the Japanese economy is indeed quite special. Since the rebound of the world stock market in 29, the rebound of the Japanese stock market is relatively small, but the trend of the yen is very strong, which is an obvious deviation between the two sides recently. However, considering the scale of Japan's public debt, compared with the euro, the position of the yen as a safe haven currency is rather embarrassing.

This deviation is obviously not the first time. At the beginning, the all-powerful Tiger Fund sold short the yen against the background of judging the poor economic situation in Japan. As a result, although the Japanese stock market continued to fall for more than three months, the yen kept rising during this period, and finally the Tiger Fund was emptied. Tiger Fund went bankrupt because of Japanese yen speculation.
