Morgan Stanley are out with their weekly client note on the Greek deal vagaries courtesy of our friends at efxnews.com

In its weekly note to clients, Morgan Stanley sticks to its EUR view in respect to the current Greek crisis.

"Should Greece sign a deal, a short-term EUR rebound should be followed by EUR weakness as investors are likely to move back into EUR-funded carry positions," MS projects

"Should Greece exit, the ECB may have to use its tool kit to keep sovereign spreads under control. Monetary easing should put the EUR under selling pressure. Ultimately, the ECB should be successful in controlling spreads, we believe," MS adds.

However, MS thinks that the calmer markets trade post Grexit, the more negative the long-term EUR outlook may become. Why?

"A Grexit represents a fundamental shift for EMU with the loss of 'irrevocability' potentially turning the union into a club of fixed exchanges rates with the possibility to leave. Peripheral assets will have to trade at a risk premium, unless EMU authorities deepen integration via further banking union and fiscal integration steps. The ECB controlling sovereign spreads successfully could turn into a long-term EUR negative factor as it may not provide the necessary 'wake-up call' to European politicians to make the necessary reforms to avoid future market tension," MS argues.

EURUSD currently back at 1.1180 after 1.1216 highs. EURGBP 0.7201 EURJPY 136.68 after heady highs of 137.30
