Japan's Ministry of Finance (MOF) said on Monday it intervened three times this
summer to support the yen, confirming earlier reports including a nearly
30-year-first joint action with the United States. MOF's quarterly daily FX
intervention data showed the operations spanned three days, surprising traders
who had expected two. On July 30 authorities bought a record JPY 7.98 trillion
(~$50.4 billion) of yen; purchases on the following days were JPY 5.55 trillion
and JPY 1.87 trillion.
