Japan intervened in the currency market three times during the spring Golden Week holiday to prop up the yen, adding an extra round to maximize the psychological impact on investors. This effort was part of a coordinated involvement between the U.S. Treasury and the Bank of Japan, representing the first joint intervention between the two countries since 1998.
The coordinated action initially lifted the yen from above 163 to as low as 155 to the dollar. Although dollar weakness pushed the yen up as much as 1.1% on Friday, the currency has since surrendered nearly half of its intervention-driven gains. By August 7, the yen traded around 158.45, falling from the strong point of 155.23 reached on August 3.
U.S. and Japanese officials have warned investors that they remain determined to defend the yen if needed. While most analysts had previously expected the next move higher to occur in December, the recent trend has fueled speculation among traders that authorities may step into the market once again.
