...Must have been a token effort by the fed then, with the DX falling off the bottom of the chart as they are supposed to be selling yen and filling their boots with dollars!
I reckon the BoJ would have been better off getting a big effort out of the PboC rather than the ECB only interested in pushing up the Euro, and the Fed - clearly not interested in pushing up the dollar, and limiting themselves to cross rates.
Already the critical USDYEN rate retraces the move caused by the so-called "G7 intervention".
You don't push yen longs off the pot with a one day move, as in this day and age, one day moves counter-trend are called "corrections" and have a bad habit of giving it all back as soon as possible afterwoulds!
You push people off the pot with a move so broad that both yen longs and USD shorts all get margin calls when the "intervention" causes a "chart break" by continuing day after day - until the market tanks without further intervention. because a trend change is recognised on the charts that so many use.
I don't think "intervention" has ever achieved this in the past though, perhaps because of the half-hearted nature of such actions.
