As markets replay the same identical reaction to the same identical Greek news that we saw back on July 21, 2011 (and we all know where that went), something else entirely and more troubling is going on behind the scenes. Because as the world was transfixed on regurgitated news out of Greece, which will without a shadow of a doubt end up with a far worse 2020 debt/GDP scenario than the IMF's downside case per the sustainability report (first posted in its entirety here on Zero Hedge last night, and which assumes just a 1% decline in Greek 2013 GDP), China just escalated currency wars into outright trade wars. Because as China Daily reports, "Chinese exports are set to get a tax boost." Translated: even as China pushes the CNY higher in infinitesimal and irrelevant increments to appease US Congress, it has just taken out the trade stimulus bazooka. Why? "Export tax rebates will be increased this year in response to an export decline triggered by the European debt crisis. The move, which Commerce Ministry officials said will be implemented when the time is appropriate, will be the first increase since 2009." Still think Europe is fixed? China's answer: nope.[Quote from the China Daily follows]
