Japan’s foreign exchange reserves decreased by more than 2% in the month to the end of March, which was their largest reduction since the publication of such statistics. This was announced on Thursday by the Ministry of Finance of the country.

As of March 31, Japan’s foreign exchange reserves amounted to almost $1.4 trillion. Their reduction is primarily due to the cheapening of U.S. government securities, in which Tokyo holds part of its reserves.

The fall of the euro against the dollar was also affected, the Japanese Finance Ministry said.
