Proving once again that when it comes to fudging numbers, Japan (which previously was best known for changing the minimum legal radiation absorption dose on a daily basis following the Fukushima disaster, anyone remember that?) is leaps and bounds ahead of even China and the US, the Nikkei reports that the Japanese government will change the method it uses to calculate GDP, and the result will be an "increase" in the country's economic output by JPY 5-10 trillion. As a reminder, Japanese GDP is currently JPY 540 trillion, so in essence the math fudge could add about 2% to Japanese "growth." Accordingly, the main difference is inclusion of interest rate spread earned by financial institutions: we were wondering how long until blowing out CDS spreads would add to sovereign GDP. We now know. The new method will be applied to figures to be announced Friday. At least Japan has not yet adjusted its GDP pro forma for foreign currency gains vis-a-vis the dollar (there is time). And that's how things are done in a Keynesian world in which everything is now fraud, lies and relentless number fudging. Furthermore, we are 100% certain no analyst will look at the number on an apples to apples basis, and the result will be a miraculous Japanese golden age. Expect this experiment in excel spreadsheet modelling to come to a developed banana republic near you very soon.
