i am betting on a grexit, euro trying to stop fed from raising rate. they hope that with grexit, they can impact the the US economy which i think it will. but come to say that the 0.25bps interest rate is considered very little. even americans do not wish the rate to be raised, they are planning job cuts on the way. however, if fed don't raise, they may have further problem dealing with inflation later on. so it's all dilemma!
Actually Grexit has been priced into the markets. Whats happening isnjust emotions trading. Greece going either way is good news. The problem is when they refuse to move either way and stuck in the middle. Actually Greece is a tiny economy and their situation has no real bearing internationally. It is just that everyone is looking at Euro as a whole and what actions ECB and IMF will take that is causing the jitters
