Currency intervention - who is in and out?

The week has shown that there is an increase in active exchange rate intervention and talk about governments moving FX rates. This is just a short list but shows how the markets are being driven by active government action. The currency wars are being fought all over the world but not with the US.

• Aussi Reserve Bank Governor Glenn Stevens - happy with interest rates - no intervention;
• Swedish Riksbank Stefan Ingves - no problem with 16 year high on the trade weighted krona - no intervention, although the markets thinks this is a possible;
• BOE policy maker David Miles - need more stimulus -  intervention through monetary policy;
• Bank of Korea - too much appreciation versus yen - good chance of won intervention;
• Philippine central bank -  may employ "appropriate macroprudential measures to address any financial stability pressures that could results from further surges in capital inflows; 
• Peru Central bank intervening;
• Thai baht - no intervention but talk about relative value versus rest of Asia;
• Brazil - less direct intervention and fight of capital inflows but inflation fighting now underway - issue of whether exchange rates will be a tool in this inflation fight.
