A brief snippet from MS on the euro, I've tagged it under technical analysis (bolded bit below) but its a chunk of fundamentalism that's the preamble

why FX markets may no longer find yield and interest rate differentials as a reliable FX guide

  • The answer lies in the relative size of FX-unhedged flows. About US$10trn of outstanding global bonds have become negative-yielding, suggesting foreign flows into negative-yielding bonds only make sense when the FX hedge turns the negative yield positive.
  • Interest rate differentials determine the size of FX-hedged bond flows - with no immediate impact on FX. It is the equity-related flow determining the performance of lower-yielding currencies such as JPY and EUR.

Better China data should allow especially European equity markets to outperform and EURUSD to catch a bid. A break of 1.1280 is required to turn the EURUSD technical picture constructive.
