The Greek vote next Sunday now stands front and centre of pretty much all investment thinking, but the problem is that it may still be days and weeks before we get a true picture of what’s happened, whether a government can be formed and what their stance will be. If the new parliament cannot clearly back the existing bailout, even after a bout of horse-trading, then a game of chicken with Europe ensues. Eurogroup meets again on Thursday and there’s a German/French/Italy/Spain summit on Friday. But G20 leaders gather in Mexico as all this is unfolding, so they will certainly be quorate if some sort of global response is required to any initial market shock. What’s more, the FOMC is meeting Tuesday and Wednesday should Bernanke feel the US needs urgent insulation from the fallout regardless of broader action. But it’s certainly not beyond the bounds of reason that coordinated central bank action materializes next week if markets do indeed go skewways after the Greek poll. They have all clearly been consulting on the issue lately via telephone and bilaterals. And the assumption of more QE is there among investors. Three quarters of the 260+ funds polled by BoAMerrill Lynch this month expect another ECB LTRO by the end of Q3 and almost a half expecting more Fed QE over the same time.
