Just reading a report over Reuters newswires that the Japanese government have made an increased allowance in its 2010/2011 draft budget for foreign exchange intervention. This strikes me as unusual given that the new government were supposed to be much less interventionist. The new total war chest would then be 145 trillion yen which is a lot of intervention power. The report says that the government hasn’t intervened in the FX market in 6 years but that can only mean ‘through official channels’ as they have lots of other institutions such as Kampo which they use.
