After the global economic crisis of 2008

However, this trend of depreciation reversed after the global economic crisis of 2008. Other major currencies, except the Swiss franc, have been declining relative to the yen.

On April 4, 2013, the Bank of Japan announced that they would expand their asset purchase program by $1.4 trillion in two years. The Bank of Japan hopes to bring Japan from deflation to inflation, aiming for 2% inflation. The number of purchases is so large that it is expected to double the money supply, but this move has sparked concerns that the authorities in Japan are deliberately devaluing the yen to boost exports. However, the commercial sector in Japan worried that the devaluation would trigger an increase in import prices, especially for energy and raw materials.
