It appears the US has decided to apply a scorched earth policy to China. While we are seeing flashing headlines that the Senate just passed a China currency bill 79 to 19 (we don't know what is in the bill yet), we doubt it will be something that China will be too pleased with, as most likely there will be some language about currency manipulation and/or some such typical politician propaganda. What is more troubling is that the CME just made sure the tens if not hundreds of billions of Chinese copper collateralized Letters of Credit just lost even more value following yet another margin hike in Copper, which raised initial and maintenance margins by 15%. If China perceives US actions as provocative (and it made very clear that US overtures in Taiwan already are), we may just see an 'oopsie' moment tomorrow when the Mainland decides to offload a few billions in US Treasurys. And the cherry on top was a 28.6% margin hike in Platinum: a direct warning to gold and silver longs once again.
