There seems to be a real disconnection between the problems / tensions in China, Ukraine, Turkey, Thailand etc and market sentiment.
Even in the US the market has happily swallowed Yellen’s speech that data weakness is all related to bad weather (US equities rose to record highs overnight while the VIX index has edged lower). Well once the weather improves the data had better improve too otherwise that theory will be shot to pieces and markets will be hit.
In particular there really does appear to be a surprisingly degree of complacency towards events in Ukraine (see earlier comments). On that note even if the Ukraine avoids default via money from US/Europe/IMF tensions with Russia remain a major issue.
In terms of FX reaction JPY and CHF could face more upward pressure while the EUR is looking increasingly exposed. High beta FX EM FX will look increasingly vulnerable against this background.
What is surprising is that both major FX and EM FX implied volatility indices (1m, 3m) are tracking below their historical vol indices. The low level of volatility in both FX and equity markets looks unsustainable.
