(ZeroHedge) On August 11, China devalued its currency, and in the subsequent 3 days the onshore Yuan, the CNY, tumbled by some 4% against the dollar. Then, as if by magic, the CNY stabilized when China started intervening massively, only this time not through the fixing, but in the actual FX market.
This means that while China has previously been dumping reserves as a matter of FX policy, after August 11 it was intervening directly in the FX market, with the intervention said to really pick up after the FOMC Minutes on August 19, the same day the market finally topped out, and has tumbled into a correction since then. The result was the same: massive FX reserve liquidations to defend the currency one way or the other.
And yet something curious emerges when comparing the traditionally tight, and inverse, relationship between the S&P and the Treausry long-end: the drop in yields has not been anywhere near as profound as the tumble in stocks. In fact, the 30 Year is wider now than where it was the day China announced the Yuan devaluation.
